“As escavadeiras liugong são poderosas, fácil de operar, e confortável para dirigir, tornando-os excelentes equipamentos,” disse Aumarico, um operador de escavadeiras LiuGong, num estaleiro de construção num distrito comercial não muito longe de Abidjan, a capital económica da Costa do Marfim. Atrás dele, não muito longe, quatro peças de equipamento LiuGong, incluindo carregadores, escavadeiras, rolos compactadores, e alunos, estavam trabalhando metodicamente, escavação, transferindo, and leveling the foundation in one go.

Equipamento LiuGong recebe elogios de parceiros da Costa do Marfim

Entende-se que Abidjan, na Costa do Marfim, tem um clima de floresta tropical, com altas temperaturas e umidade durante todo o ano, tornando o ambiente de trabalho relativamente severo. “Sob tais condições, muitas marcas europeias e americanas “não estão acostumadas com as condições locais,’ enquanto equipamento LiuGong, com seu bom desempenho, ainda tem um bom desempenho e ganhou elogios dos clientes,” disse Liu Qiaoli, o Gerente de Vendas para a África Ocidental da LiuGong. É relatado que LiuGong exportou mais de 20,000 unidades de diversos produtos para África, com usuários em quase todos os países africanos. Este ano, eles entregaram mil unidades ao governo de Gana de uma só vez. “A África é um dos primeiros mercados estrangeiros para LiuGong. Desde que a LiuGong entrou no mercado africano, vem crescendo e se fortalecendo. A LiuGong estabeleceu subsidiárias e escritórios em vários mercados importantes em África, e valoriza operações localizadas, fornecendo excelentes produtos e serviços aos clientes locais.”

1. Visão geral do projeto

O projeto de instalação de cabos sem escavação da Malásia atravessa o estuário da Baía de Lumut, na Malásia, colocação de um tubo de Φ610mm com uma distância horizontal de construção de 1250m e uma profundidade de cruzamento de 26m abaixo do nível do mar. Devido à distribuição caótica de areia e lodo na área e às complexas condições geológicas, a parte da construção escolheu o XuGong XZ5000 perfuração direcional horizontal rig for construction.

2. Configuração do equipamento de perfuração

O projeto utiliza 168, 140 hastes de perfuração, equipado com um 172 motor de lama para perfuração direcional. Para expansão do furo, a combination of Φ450mm to Φ900mm cutting and bucket-type hole expanders is used for construction.

3. Tecnologia de Construção

Perfuração Direcional: A perfuração direcional é auxiliada por revestimento duplo. Primeiro, um invólucro de 16 polegadas é usado para isolar os estratos fracos e a infiltração de água do mar da seção de inclinação de entrada do solo. Então, de acordo com a curva projetada, a perfuração direcional é realizada para aproximar-se da posição horizontal, empurrando o invólucro de 12 polegadas ao longo da haste de perfuração através do invólucro de 16 polegadas, e continuando até perto da posição horizontal. Depois que o invólucro é abaixado, continue drilling according to the designed trajectory until the drill bit emerges from the ground.

Expansão do furo: A expansão do furo é realizada usando uma combinação de corte e expansores de furo tipo balde. Os expansores de furos tipo corte são divididos em quatro níveis: Φ450mm, Φ600mm, Φ750mm, Φ900mm, with the outer diameter of the bucket-type hole expanders used in combination being slightly smaller by 50mm.

Puxando Tubo: Durante puxar o tubo, a extremidade frontal do tubo é conectada a um expansor de furo tipo balde de Φ700 mm. Devido ao layout limitado do tubo, o tubo precisa ser puxado para trás em cinco seções, requiring four weldings.

4. Perfuração Direcional em Formações Complexas

As medidas de assistência à dupla carcaça, onde o grande invólucro de 16 polegadas é usado principalmente para isolar os estratos complexos e a água do mar na seção de entrada do solo, e o pequeno invólucro é usado principalmente para limitar o espaço de flexão da haste de perfuração para evitar que a haste de perfuração quebre. Large drilling rigs can usually use the power head to drive the casing to rotate and advance.

Ao mesmo tempo, duas especificações de hastes de perfuração são usadas em combinação: 140 hastes de perfuração na frente para melhorar a eficiência da inclinação; 168 drilling rods behind to ensure the strength of the bending section of the drilling rod and prevent accidents of drilling rod breakage.

Plano de preparação de lama

Como o projeto é construído à beira-mar, os estratos contêm mais cálcio, magnésio, e outros componentes iônicos, portanto, os aditivos de lama requerem álcali puro e soda cáustica para remover íons de cálcio e magnésio da água do mar. Ao mesmo tempo, porque os estratos estão entrelaçados com camadas de areia e camadas de lodo, a estabilidade dos estratos é fraca, portanto, os aditivos de lama também precisam de cola eletrostática positiva e agentes de proteção de parede para facilitar a formação de furos e proteger a parede do furo, with the pumped mud viscosity not less than 50S.

Extração segmentada de tubo

Na construção de engenharia comum, o tubo é concluído em um puxão para trás. Se o tubo for puxado para trás em segmentos, aumentará o risco de construção, especialmente quando os estratos são complexos e o desempenho da lama não é ideal, it is easy to cause hole collapse and pipe clamping accidents.

No entanto, enfrentando mais de 1200 metros de rios, a parte da construção só pode optar por recuar em segmentos, which requires very high requirements for equipment performance parameters and technological methods.

Este puxar tubo é dividido em cinco seções, exigindo quatro soldas. Para garantir a segurança da construção, durante a soldagem, lama é bombeada para dentro do buraco a cada 20-30 minutos para manter o furo sempre cheio de lama de alta qualidade, effectively preventing the occurrence of hole collapse accidents.

According to official data released by Jamaica, the government’s investment in infrastructure construction has continued to increase in recent years, especially in the construction of roads, bridges and public facilities. The implementation of these projects has not only improved the living standards of the people, but also provided a broad market space for heavy machinery such as excavators. Além disso, the booming tourism industry has also promoted the growth of related construction activities, further promoting the prosperity of the excavator industry.
From the perspective of the supply chain of the excavator industry, Jamaica mainly relies on imports to meet its market demand. Internationally renowned brands such as Caterpillar, Komatsu and Hitachi have a place in the market. These brands of excavators are favored by Jamaican users for their high efficiency, durability and advanced technology. No entanto, the high cost and maintenance costs of imported equipment have also become a factor restricting the development of the industry.

Despite the cost challenges, the outlook for the Jamaican excavator market remains optimistic. With the government’s commitment to improving productivity and promoting economic development, more infrastructure projects are expected to be launched in the next few years. This will directly drive the demand for excavators and related construction machinery. Ao mesmo tempo, with the advancement of technology, the performance of new excavators has been continuously improved, and they are more energy-efficient and environmentally friendly, which will also help reduce operating costs and improve the overall competitiveness of the industry.

In addition to infrastructure projects, Jamaica’s mining industry is also an important source of demand for excavators. Mining is an important part of Jamaica’s economy, especially in bauxite and gold mining. As the global market demand for metals grows, Jamaica’s mining industry is expected to expand further, which will bring more opportunities to the excavator industry.

Faced with such a market environment, participants in the Jamaican excavator industry need to adopt strategies to seize development opportunities. Primeiro, companies should strengthen cooperation with international manufacturers and introduce more advanced technology and equipment. Second, considering the issue of maintenance costs, companies can enhance customer loyalty by providing training and after-sales services. Finally, companies can also explore the second-hand excavator market to meet the needs of cost-sensitive customers.

In summary, although the Jamaican excavator industry faces some challenges, the overall development prospects are still very optimistic, driven by national infrastructure construction and mining development. By continuously introducing new technologies, improving service quality and expanding market channels, Jamaica’s excavator industry is expected to achieve more stable and sustainable development.

It is worth noting that the development of the industry is also inseparable from policy support and regulation. When formulating relevant policies, the Jamaican government should consider how to balance the relationship between industry development and environmental protection, and ensure that the use of construction machinery such as excavators will not cause irreversible damage to the ecological environment. Ao mesmo tempo, the government should also encourage local companies to participate in the manufacturing and maintenance services of excavators to promote the development of local industries and technology accumulation.

In short, the current development status of Jamaica’s excavator industry shows a strong growth momentum, and the future prospects are full of infinite possibilities. With the continued growth of the national economy and the government’s emphasis on infrastructure construction, the excavator industry will play a more important role in Jamaica’s economic development.

At present, the Kenyan excavator market is in a stage of rapid growth. According to relevant data, the annual growth rate of Kenya’s construction industry remains at around 5%, which directly drives the demand for excavation machinery and equipment. The “Vision 2030” plan launched by the Kenyan government aims to comprehensively improve the country’s industrialization level and infrastructure, including large-scale construction projects. The implementation of these projects requires a lot of earthwork operations, which in turn promotes the expansion of the excavator market.

Despite the continued growth in market demand, the Kenyan excavator industry still faces some challenges. Primeiro, there are a large number of second-hand excavators on the market, which has a certain impact on the sales of new machines. Secondly, due to the lack of professional operators and maintenance personnel, the efficiency of some equipment is not high, which limits the development speed of the industry. Além disso, insufficient liquidity is also an important factor restricting the expansion of enterprises.

From the perspective of competition, the Kenyan excavator market is dominated by several internationally renowned brands, such as Caterpillar, Komatsu and Hitachi. These companies have won wide recognition in the market with their advanced technology and reliable product quality. No entanto, local companies are also gradually emerging and attracting customers by providing more affordable products and flexible services.

Looking to the future, the development prospects of the Kenyan excavator industry are generally optimistic. With the continued growth of Kenya’s economy and the further implementation of the “Vision 2030” plan, the market demand for the industry is expected to maintain an upward trend in the next few years. Além disso, with the advancement and innovation of technology, more efficient and environmentally friendly excavator products are expected to enter the market, which will further enhance the competitiveness of the industry.

In order to promote the healthy development of the industry, the Kenyan government and enterprises should take the following measures: Primeiro, increase the training of excavator operation and maintenance personnel to improve the efficiency of equipment use; second, encourage financial institutions to provide more loan support to enterprises and individuals who purchase new machines to ease financial pressure; third, strengthen market supervision, ensure the quality of second-hand equipment, and protect consumer rights.

In summary, although the Kenyan excavator industry faces many challenges, the future of the industry is full of opportunities as the country’s infrastructure projects continue to advance and market demand grows. Through continuous technological innovation, talent training and policy support, the Kenyan excavator market is expected to continue to maintain a steady growth trend.

As an important part of advanced manufacturing, excavator remanufacturing is a series of technical measures or engineering activities that are guided by the design and management of the whole life cycle of the machine, aiming to improve the performance of waste machines, and using advanced technology and industrialization methods to repair and transform excavators that are about to be scrapped.

The quality and characteristics of remanufactured excavators are generally not lower than those of new products, but the cost is only 50% of that of new products, and energy and materials are saved by 60%, 70%, and the emission of atmospheric pollutants can be reduced by more than 80% during the remanufacturing process.

At present, Chinese companies have a large number of second-hand excavator equipment, and there is a strong demand for such second-hand equipment in Africa, Southeast Asia, South America and other places, and the price continues to rise. In order to accelerate the cultivation of new foreign trade momentum, my country’s excavator remanufacturing industry is developing rapidly, and leading domestic excavator manufacturing companies are stepping up their layout. Some companies are committed to building an excavator remanufacturing industry cluster and becoming the leading industry standard setter; some companies are deploying excavator remanufacturing in multiple locations across the country; some companies regard remanufacturing as the core content of “value chain construction”, one of the four strategic options for aftermarket business; some companies focus on improving the excavator remanufacturing service system, and so on.

At present, my country is accelerating the promotion of excavator remanufacturing quality upgrades, giving full play to the advantages of a major excavator manufacturing country, accelerating the promotion of excavator remanufacturing exports, and constantly cultivating new foreign trade momentum in the manufacturing industry such as excavators. Ao mesmo tempo, the world today is undergoing a major change that has not been seen in a century, and the international landscape is undergoing complex and profound changes. Scientific and technological progress is changing with each passing day, the international financial crisis has far-reaching impacts, and new trends have emerged in the world economic landscape and international power comparison. Faced with a complex and sensitive international economic environment, my country’s excavator remanufacturing exports are also facing a series of challenges and risks.

Primeiro, the risk awareness and risk resistance capabilities of excavator remanufacturing export trading companies need to be improved, and guidance is urgently needed. Second, due to the lack of an effective evaluation mechanism, some unqualified excavators have entered the remanufacturing industry. Some of the process flows have not been standardized, and there is a lack of effective quality control. The quality of remanufactured excavator products is not very stable, and there are hidden dangers of trade disputes. Third, the relevant enterprises are not familiar with the market rules and legal systems of relevant overseas countries (regions), the collection of overseas market risk information is not comprehensive and accurate, and the risk assessment and early warning mechanism is not sound, so enterprises are prone to passiveness in the remanufacturing export trade of excavators. Fourth, due to the late start of the remanufacturing export trade of excavators, my country’s voice in this field is limited, and the existing international legal rules for the remanufacturing export trade of excavators are not conducive to the rapid development of my country’s remanufacturing exports of excavators.

Unfamiliar overseas markets, unfamiliar language and culture, different legal systems and trade rules, etc., are all obstacles that excavator remanufacturing enterprises must overcome when going abroad to participate in international competition. In order to help Chinese manufacturing enterprises, including excavator remanufacturing, “go overseas” and quickly connect with overseas market demand, it is necessary to improve the three major overseas risk prevention and control systems.

Improve the overseas risk prevention and control self-protection system

At present, the international environment is complex and severe. In this context, my country’s excavator remanufacturing exports need to further improve their own overseas risk prevention and control guarantee system.

Primeiro, all enterprises should work hard to improve their internal strength, establish and improve standardized remanufacturing process and effective quality control system, and ensure the quality of remanufactured products.

Second, strengthen the main responsible department for legal risk prevention and control, improve the overseas legal risk prevention and control work system, and deploy legal staff in the field of foreign-related excavators in a targeted manner.

Third, strengthen the comprehensive research on the relevant market rules and legal systems of the target countries (regions), clarify the legal risk points and actively avoid them, and take the initiative in risk prevention.

Fourth, strengthen the risk assessment of export behavior, guide and train risk prevention and control departments and staff to make correct decisions and respond effectively, do a good job in early warning and prevention, and minimize risks.

Fifth, improve risk response capabilities, be good at learning and using the legal system and rules of international trade in excavators, actively handle risks in an emergency, and do not fight in a chaotic manner and respond in an orderly manner.

Sixth, enhance the awareness of choosing to apply Chinese law and increase the predictability of case results.

Improve the policy support system for overseas risk prevention and control

At present, my country’s excavator remanufacturing industry is developing in different states in various places. To better protect the rights and interests of export enterprises, the policy support system for overseas risk prevention and control can be improved from four aspects.

Primeiro, benchmark international rules to guide the establishment of national (international) standards for excavator remanufacturing. In view of the current situation that enterprises have little technical accumulation and lack relevant standards, promote institutional opening such as rules, management, and standards, and establish a relatively systematic excavator remanufacturing process and quality standards. Ao mesmo tempo, establish and improve the economic and trade cooperation promotion system with Africa and the Regional Comprehensive Economic Partnership Agreement (RCEP) industry docking system, make full use of opportunities such as the joint construction of the “Cinto e estrada”, RCEP, and the African Continental Free Trade Area (AfCFTA), and create a national excavator remanufacturing export platform. Actively lead and supervise relevant enterprises to benchmark and standardize production and operation behaviors, and try to reduce unnecessary risks in foreign trade.

Second, improve the overseas risk information collection mechanism. Relevant institutions can comprehensively and accurately collect overseas market risk information, analyze and organize it in a timely manner, and publish it in a unified manner for export, so that Chinese enterprises can form a pre-understanding and accurate prediction of the risks of target countries (regions) and avoid overseas risks in a timely manner.

Third, improve the overseas legal risk assessment and early warning mechanism. In view of the legal risk factors that Chinese excavator remanufacturing enterprises may face in target countries (regions), establish a scientific legal risk assessment and early warning mechanism. Relevant departments can timely conduct a comprehensive assessment of the laws and policies of the main target countries (regions), and timely warn of countries (regions) where risks are more likely to occur.

Fourth, improve the overseas legal risk response and disposal mechanism. Strengthen training, guidance and support for emergency disposal of legal risks of relevant enterprises, rely on our official communication channels for mediation, use international sister city cooperation relations to smooth dispute prevention and control and communication channels, and improve the working mechanism for relevant departments to take the lead in coordinating with all parties to deal with complex situations. For major risk countries (regions), cultivate and establish an overseas legal risk response and disposal expert database, provide more legal assistance to Chinese companies involved, and improve the scientificity and initiative of disposal.

Improve the international protection system for overseas risk prevention and control

In the process of continuously promoting high-level opening up, we should actively lead and expand the international protection system for overseas risk prevention and control, and maximize the protection of the legitimate rights and interests of relevant Chinese companies under the rules of international law.

Primeiro, make full use of national bilateral treaties. There are many countries that have signed bilateral treaties with my country. We should make full use of this advantage. Under the expanding mutual trust and mutual benefit bilateral treaty trade and investment protection system, we should actively seek special cooperation in excavator remanufacturing export trade with target countries (regions) such as Africa, Southeast Asia, and South America, and promote greater achievements in my country’s excavator remanufacturing export trade.

The second is to actively create an international business environment. We should make full use of international cooperation practice platforms such as the joint construction of the “Cinto e estrada”, RCEP, and the China-Africa Economic and Trade Expo, and take the concept of building a community with a shared future for mankind as the guidance, coordinate and integrate foreign affairs resources, deepen friendly city cooperation, and widely build platforms for good cooperation with countries in the region and the world, so as to create a safer and more harmonious international business environment for my country’s export-oriented enterprises and prevent overseas risks from the source.

The third is to help expand my country’s voice in excavator remanufacturing exports. We will continue to actively participate in promoting the institutional and mechanism building of international platforms such as the Shanghai Cooperation Organization, BRICS, and the G20, put forward China’s concerns and suggestions in the fields of economic trade, investment development, human rights protection, dispute mediation, etc.. within the framework of multilateral (bilateral) treaties, expand my country’s voice in the field of excavator remanufacturing and export, and contribute wisdom to the construction of fair and reasonable new international legal rules.
