Stainless steel hand chain hoists include hand-pulled chains and wrench hoists. Hand-pulled chains lift heavy objects by pulling on the chain, with a compact structure and convenient portability. Wrench hoists are mechanical manual traction tools, also known as tensioners. Their up and down hooks use rotating hook design for high operational flexibility, making them suitable for use in narrow spaces. They can not only be used for towing and tightening but also for lifting. Hand-pulled chains operate by pulling on the side of the object through the hand chain to drive the lifting chain, achieving ascent.
