During the design and manufacturing process, we fully considered the local working environment and climatic conditions of Pakistan, ensuring that the crane can adapt to harsh environments such as high temperature and dustiness, and always maintain stable performance. At the same time, we use high-strength steel and advanced welding technology to ensure the structural strength and durability of the crane.

The crane’s double-girder bridge structure ensures excellent stability and load-bearing capacity while working. Its maximum lifting capacity is 3 tons, which can easily handle the handling tasks of various heavy-duty components in the motorcycle manufacturing process. In addition, the crane is equipped with advanced control systems and safety devices, such as overload protection, limit switches, etc., ensuring safety and reliability during operation.

In terms of installation, since the climate conditions and working environment in Karachi, Pakistan are different from where our manufacturing plant is located, some adaptations need to be made during the installation process. We dispatched a professional technical team to the site and worked closely with local engineers and technicians to complete the installation of the crane. During the installation process, the team also took into account local safety regulations and operating procedures to ensure compliance and safety throughout the installation process.

Due to the large size and weight of the crane, there may be some minor deviations or errors during installation. During the trial operation, we found that some movements of the crane were not smooth enough and there were some minor stucks or vibrations. In order to solve this problem, our technical team conducted a detailed inspection and analysis of the crane’s structure, found out the root cause of the problem, and made precise adjustments and optimizations to ensure the crane’s smooth and smooth operation.

In addition, during the trial operation, we also noticed the impact of the local working environment and climatic conditions on the crane. For example, the high temperatures in Karachi, Pakistan, may have a certain impact on the crane’s lubrication system and cooling system. Therefore, our technical team conducted special inspections and adjustments on the crane’s lubrication and cooling system to ensure that it can operate normally in high-temperature environments.

Finally, we also noted that local operators may not be familiar enough with crane operation and maintenance. In order to ensure the safe and stable operation of the crane, our technical team provides local operators with detailed operational training and maintenance guidance to help them better master the operation and maintenance skills of the crane.

The actual application of the crane in the motorcycle manufacturing plant in Karachi, Pakistan is very ideal and has been highly praised and recognized by customers. This further proves the competitiveness of our product quality and technical strength in the international market.
