Overload Device

An overload device is available on winches with the emergency shutoff option. Overload device operation is based on differential pressure between air motor inlet and exhaust. The overload device is factory preset to actuate at 150% (± 25%) of winch rated capacity. When an overload condition is sensed, the valve poppet closes, to cut off supply air to winch, stopping winch operation. If an overload shutoff occurs, winch load must be reduced. Reset the overload valve and operate winch in payout direction to lower load. Refer to ‘Emergency Stop Reset’ section.

Checking Overload Valve Setting

1.Attach load line to a load that is calibrated to maximum load for which winch is rated.

2.Move control lever to haul-in position. If winch does not lift load, adjust the adjustment screw. Refer to ‘Overload Valve Adjustment’ section“Overload Valve Adjustment (optional feature)” on page 26.

Setting the Overload

Refer to MHP2049 on page 16 and MHP2216 on page 27. Attach load line to a load that is calibrated to 150% of winch rated capacity. Shift control lever to haul-in position.

1.If overload valve activates, reset overload valve. Winch is ready for normal operation.

2.If winch lifts load, lower load. Turn adjustment screw counterclockwise in 1/4 turn increments until overload valve activates when control lever is shifted to haul-in position. After each 1/4 turn, retest winch.

Emergency Stop (optional feature)

Refer to Dwgs. MHP1485, MHP0754 on page 16 and MHP1892 on page 17.

The emergency stop device is located at air inlet of winch on local control models, and on pendant on remote control models. When activated, winch drum rotation will immediately cease.

1.To start winch operation depress the ‘ON’ button.

2.To operate winch, depress appropriate ‘Haul-in’ or ‘Payout’ lever.

3.In event of an emergency all winch operation can be stopped by pushing the emergency stop button. This will prevent air from reaching winch motor, engage winch automatic brake(s) and stop winch haul-in or payout movement.

4.If depressed, the ‘OFF’ button will also stop winch operation.

5.To reset Emergency Stop Valve:

a.Locate serrated ring directly below emergency stop button. Rotating serrated ring clockwise, will cause emergency stop button to ‘pop up’.

b.Depress emergency stop valve ‘ON’ button.
