Electric hoists represent their own machinery, strength, and toughness, while the stage is elegant, flowing, and soft, with conflicts and collisions between the two.
A hand chain winch is a small lifting device that uses manual chain pulling as its power source. It realizes the lifting or traction of heavy objects through a gear transmission system, and is widely

Product Details
Installation of small livehouse stages: Due to space constraints, small livehouse stages usually have an area of less than 10 square meters and a floor height of only 3-3.5 meters. Restricted by the original building structure, most of them do not have pre-reserved interfaces or load-bearing points for fixed electric lifting equipment, which places higher requirements on the flexibility and adaptability of equipment hoisting. The suspension of equipment during the preparation period requires a hand chain winch as the core tool: first, according to the actual load-bearing conditions of the site, the winch must be fixed on the simple hanging rails above the stage (mostly made of lightweight aluminum alloy, which need to be pre-fixed to the ceiling keels or beams with expansion screws) or wall-mounted load-bearing frames (usually made of angle steel welded structures, which must pass load tests to ensure they can bear a static weight of at least 50kg). During fixation, anti-slip washers and lock nuts must be used for double reinforcement to prevent loosening caused by vibration during equipment operation. In terms of position accuracy control, the chain of the hand chain winch can assist in adjusting the distance between the equipment and the edge of the stage, which is usually maintained at a safe interval of 0.5-1 meter. This distance not only prevents the equipment from protruding beyond the stage edge and causing obstacles in the audience area but also reserves sufficient activity space for actors' interactive performances at the stage edge.
