Chester Zephyr Twin Hook Image

The Chester Zephyr Twin Hook Hoist drives two separate load chains simultaneously from a single hand chain. Long and bulky loads can be more easily and evenly lifted with the Twin Hook Hoist. Available with hooks up to 16 feet between centers and extra length lifts as needed. Suspension hooks can be hung from trolleys or fixed positions.

Features and Benefits

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.
