Hoist Motor and Gear Train
The hoist motor and gear train are designed and built to meet the most severe demands for hoisting service requiring frequent reversal and high starting torque. The motor is work rated, with Class F insulation.
The gear train consists of hardened and polished helical gears and pinions. Compact design with low weight /output ratio provides highly efficient, quiet, and long lasting operation.

|
Trolley Drive
The trolley drive consists of a pole changing squirrel cage gear motor. Integral disc brakes are specially designed for crane service. Low torque, high inertia drives provide smooth acceleration and decelerations without excessive load swing.
Travel motors are provided with DC disc brakes, quick disconnect plugs, and Class F insulation.

|
Brake
A DC rectified magnet actuated disc motor brake is automatically applied in the event of power failure. These self-adjusting and virtually maintenance-free brakes are provided with asbestos-free, non-polluting brake linings. Expected service life is one million operations before requiring the first adjustment.

|
Limit Switches
Easily adjustable dual upper and single lower gear type limit switches bring the load hook to a positive stop at any desire position in both the hoisting and lowering directions.
|
|
Overload Limit
An overload limit monitors load and prevents operator from lifting loads greater than the hoist's capacity.
|
|
Rope Guide
Our heavy-duty rope guide prevents rope from being unbraided and cut and protects the operator from injury.
The guide keeps the rope in contact with the drum grooves, even under slack rope conditions.

|
Tow Arm and Travel Limit Switch
Adjustable tow arm and trolley travel limit switch are available as standard options.
|
|
Quick Disconnects
Pre-tested, multi-pin quick disconnect plugs and socket connections for fast, safe, mistake-proof electrical assembly.
|
|
Wheels and Drive Pinions
Large diameter machine tool steel quality wheels and drive pinions are available for nearly any flange width or beam style.
The wide wheels create less flange bending stress to reduce beam size requirements.

Bottom Block
Heavy-duty bottom block with safety latch and hardened sheaves.
