Product Description
Zephyr Clevis Type
The Chester Zephyr Clevis Type Hoists are steel framed hook suspended hoists built and tested to rigid specifications of quality and performance, to exceed industry standards. Offers headroom advantage, retains rock-and-swivel flexibility of standard trolley suspension.
Alloy Steel for Added Durability
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.
Rugged, Lightweight Design
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
Smooth, Trouble-Free Operation
Load and hand chain guides assure smooth, trouble-free operation
Precision Load Handling
A fast acting Weston Style brake provides smooth, positive load handling
Mechanically-Sealed, Grease-Tight Enclosure
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.
Durable Internal Gears, Pinions & Pinion Shafts
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.
Flexible and Adaptable
The Zephyr design is easily adaptable to meet the special requirements of most applications
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.
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.
Chain Stripper
Ductile Iron.
Easy Dismantling
Using only a small wrench and screwdriver, operators can make periodic inspections or replace chains and parts with ease.
Load Chain Guide
Completely shrouds load sheave, guides chain into load wheel and efficiently shields these parts from entry of foreign objects.
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.
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.
Pinion Cage
Spline fitted to the steel load wheel shaft.
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.
Driving Spindle
Made of nickel-chrome-molybdenum alloy steel with machine-cut teeth. Operates on heavy-duty bearings.
Bottom Hook Assembly
Consists of forged alloy steel hook operating on thrust bearing with full swiveling action.
