A GJJ hoist refers to a construction elevator or lift manufactured by GJJ, a well-known Chinese brand specializing in construction machinery. Also known as a construction hoist, builder’s hoist, or rack and pinion elevator, the GJJ hoist is primarily used to transport workers and materials vertically on construction sites, especially in high-rise building projects.
GJJ hoists are renowned for their safety, reliability, and durability. They typically consist of one or two cages that travel along a mast tower using a rack-and-pinion drive system. With lifting capacities ranging from 1 to 3 tons and lifting heights reaching over 300 meters, GJJ hoists offer flexible solutions for different types of construction tasks.
Common applications include:
l Transporting personnel and tools
l Carrying building materials such as bricks, cement, and steel
l Temporary elevator access during building construction or maintenance
Thanks to features like frequency conversion control, overload protection, and automatic leveling, GJJ hoists help improve efficiency and safety on modern construction sites worldwide.
