Description
Chester Hoist Zephyr™ Hook Suspended Hoist, 3 ton, 8 ft Lifting Height, 21-1/4 in Minimum Between Hooks, 1-11/32 in Hook Opening, 60 lb Pull to Lift, 18 ft to 6 in Load/15 ft to 6 in Chain Length, Steel Chain, Weston Brake
Features:
- Sealed enclosure keeps lubrication in, making the Chester Zephyr™ a lifetime lubricated hoist under normal conditions, no protruding parts prevent snagging
- Shock resistant, stamped covers made of heavy gauge steel, two rolled steel sections in the frame and strong alloy steel suspension provide durability and shock resistance
- Easy dismantling, using only a small wrench and screwdriver, operators can make periodic inspections or replace chains and parts with ease
- Gear train, center planetary system uses modified involute stub tooth form, gear teeth are cut from solid alloy steel blanks and heat treated for added strength
- Durable internal gears, pinions and pinion shafts, internal gears and pinions are made of nickel chrome molybdenum alloy steel, internal gear is heat treated for durability and strength
- Machine cut teeth are heat treated and mounted on heavy duty roller bearings, gear and pinion shafts are made of rigidly mounted alloy steel and are surface hardened and ground
- Pinion cage, spline fitted to the steel load wheel shaft
- Driving spindle, made of nickel chrome molybdenum alloy steel with machine cut teeth, operates on heavy duty bearings
- Load wheel, heat treated cast steel with spline fit to load shaft, chain pockets are accurately formed, and load wheel can be reversed when new chain is installed to effect double life
- Ductile iron chain stripper
- Load brake, positive action, Weston type load brake with uniform composition lining and quiet action, forged alloy dual pawls
- Load chain guide completely shrouds load sheave, guides chain into load wheel and efficiently shields these parts from entry of foreign objects
- Load chain made of durable steel, links are precision formed to fit pockets of load wheel, heat treated for high tensile strength and hardness
- Hand chain guide, designed to eliminate fouling and permit angular pull on the hand chain
- Top hook assembly, permits hoist to rock and swivel under load, alloy crosshead rocks in rolled steel straps welded to frame, alloy hook is heat treated, drop forged alloy steel hook will open before fracturing
