AIR WINCHES

Air Tugger Winch, Air Lifting Winch

(Model numbers below)

Winch Drums
Drums are steel fabricated and designed to specific loading capacity. Drums are sized according to ASME B30.7.94 to provide a minimum pitch diameter of 15 times the nominal rope diameter on Air Tuggers and 18 times on our Air Lifting Winches.

Direct Drive
A simple, direct-drive design increases the efficiency of the winch and eliminates drive chains or bull gears to maximize power output.

Any Position
An open-base design permits mounting in horizontal or vertical positions. Loads can be pulled through the base itself, which is particularly useful in limited-space installations.

Ball & Roller Bearings Throughout
Friction load loss is reduced to a minimum through the use of ball and roller bearings. No bushings means higher efficiency and more power for pulling.

Power In — Power Out
For added safety, all winches are fully reversible. This gives the operator complete control of the winch load in both directions at all times.

High Service Factors
Jeamar winches are designed and manufactured for continuous, heavy-duty operation with a minimum service factor of 1 (one).

Gear Reducers
All Jeamar air winches have high-efficiency helical reducers plus high-capacity, anti-friction bearings for long life, low noise and high output torque. Totally enclosed reducers make them weatherproof.

Air Motors
Jeamar air motors are fully reversible vane type. Positive starting and precise control are central features of the motors, which have been designed for long life and low-cost operation. They can be stalled indefinitely under load without harm to the motor.

Control Valve
Control valves feature proportional flow with spring return to neutral for “deadman” operation. Valves control the winch speed by varying air flow to the motor. With the control released, air flow is cut off, stopping the winch. Controls are supplied loose to allow for mounting that is appropriate to the application.

Air Brake
Standard on all heavy duty lifting winches, the air brake is a disc type that is activated automatically in the event of a power interruption. The brake will stop the winch and hold the load securely. When the Air Tugger is used to move loads on an incline, it is essential that a brake be used.
