Gears and pinions are alloy steel, machine cut, heat-treated and mounted on heavy-duty roller bearings. Precision formed alloy steel load chain runs in a reversible 5 or 6 pocket load sheave.
Standard construction features include a lightweight steel frame, heavy duty steel covers, ball bearing supported load shaft and a durable, efficient, grease lubricated planetary gear train
Load and hand chain guides assure smooth, trouble-free operation
A fast acting Weston Style brake provides smooth, positive load handling
Heavy steel housings keep out most foreign material, protecting precision-machined working parts. Sealed enclosure keeps lubrication in, making the Chester Zephyr a lifetime-lubricated hoist under normal conditions. No protruding parts prevent snagging.
Internal gears and pinions are made of nickel-chromemolybdenum 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.
The Zephyr design is easily adaptable to meet the special requirements of most applications
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.
Stamped covers made of heavy-gauge steel, two rolled steel sections in the frame and strong alloy steel suspension provide durability and shock resistance.
Using only a small wrench and screwdriver, operators can make periodic inspections or replace chains and parts with ease.
Completely shrouds load sheave, guides chain into load wheel and efficiently shields these parts from entry of foreign objects.
Center planetary system uses modified involute stub tooth form. Gear teeth are cut from solid alloy steel blanks and heat treated for added strength.
Made of durable steel. Links are precision formed to fit pockets of load wheel. Heat treated for high tensile strength and hardness.
Designed to eliminate fouling and permit angular pull on the hand chain.
Spline fitted to the steel load wheel shaft.
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.
Made of nickel-chrome-molybdenum alloy steel with machine-cut teeth. Operates on heavy-duty bearings.
Consists of forged alloy steel hook operating on thrust bearing with full swiveling action.
