In recent years, China's oil and gas pipeline construction has entered a peak period, and the difficulty of pipeline installation and construction in mountainous areas is much greater than that in urban areas. In order to transport a large number of steel pipes and construction equipment to the construction site, construction personnel need to comply with the mountain terrain, while also taking into account the purpose of saving time, effort, and protecting pipelines. Hand pulled hoists have shown obvious advantages in this situation.

Hand pulled hoist is a small mechanical equipment that can lift several tons or even dozens of tons of heavy objects to a high place without relying on a power source. It is small in size, easy to carry, and flexible in use. It can be hung on a fixed point or on mobile gantry cranes or lifting tripods, bringing great convenience to pipeline transportation and installation work.

Directly using steel wire rope to connect the installed and uninstalled pipes, and using a chain block to pull the two pipes together for installation, can ensure installation accuracy and improve work efficiency, ensuring the timely completion of pipeline construction tasks.
