New style overload clutch:
The overload clutch can be adjusted from the front of the hoist and does not effect brake performance. The overload clutch is factory set to limit Quantum from lifting loads in excess of 150% of
rated hoisting capacity.
Gear case:
Smooth and compact design with a helical/spur gear combination providing "grab free" movement and quiet, reliable operation. Optimum lubrication - Gears are lubricated with a semiliquid grease
instead of oil, which is less likely to leak, eliminates oil level checks, and clings to the gears even after long idle periods. Quantum will even work upside down.
Chain guide and wheel:
A "floating" chain guide precisely feeds chain onto a machined-matched five-pocket chain wheel. This system insures smooth, jam resistant operation, and extends load chain, and chain wheel life.
Optimized load chain:
Load chain is precision formed from alloy steel, case hardened and zinc plated. The plating is an IR proprietary process, which resists corrosion better than any standard plating offered for load
chain. Controlled elongation: Quantum chain is engineered to elongate a minimum of 10%. This ability to stretch reduces the possibility of catastrophic failure under sudden loading.
