• 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.
• Easy Dismantling
  Using only a small wrench and screwdriver, operators can make periodic inspections or replace chains and parts with ease.
• 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.
