No,we use 5-Pocket Chain Wheel: Patented guide structure ensures snag-free operation even in tilted or high-frequency rigging.

Our hoists are rated at IP66 , making them ideal for outdoor festivals and tours.

No, we use sealed gearbox + special lubricant: designed for lifetime lubrication, eliminating the risk of oil leakage and protecting your precision equipment.

We use high-density reinforced nylon chain bags with heavy-duty steel mounting brackets. Designed to with stand the weight of over 30 meters of chain without stretching or tearing, our bags ensure no "surprises" fall from the rig.

For D8+ models, we utilize a 8:1 Safety Factor. Our chains are made from high-strength alloy steel with a Matte Black Phosphate finish, specifically designed to be non-reflective under intense stage lighting.

Absolutely. Our hoists come standard with limit switches(upper and lower limiter). This allows riggers to set precise travel boundaries, preventing truss collisions and ensuring repeatable positioning.

Yes. CMHO hoists are designed for dual-orientation versatility. Whether used in a standard upright position or as a climbing hoist (motor moving with the truss), our internal lubrication and chain-guide systems ensure smooth, snag-free operation in both directions.

D8 : Single brake system:For assembly only; standing underneath is strictly prohibited.

D8+: Dual brake system :People are allowed to stand below while the electric hoist is stationary (requires dual braking and a higher safety factor).
