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