State-of-the-art AC motor brakes with all-steel discs.Multiple stacking significantly increases braking suface area, reducing ware and extending life. Quantum brake discs are guaranteed for the life of the hoist.
Advantage Smooth, quite operation - Helical spur gear combination provides grab-free movement and quite, reliable operation. A floting chain guide precisely feeds chain onto a machined-mached, five-pocket chain wheel. This system ensures smooth, jam-resistant operation. Durability - Quantum load chains are precission-formed alloy steel, case hardened and zinc-plated. The plating is an Ingersoll Rand proprietary process that resists corrosion better than any standard plating offered for load chain. Reliability - With high starting torque, Quantum motors utilize a totally enclosed non-ventilated (TENV) squirrel cage design. The H4-duty classification allows for 300 starts and 30 minutes "on-time" per hour. Class F insulation provides a total thermal rating of 145C at a 1.0 service factor, insted of the more common Class B insulation of 120C.
