BOOM HOIST RATCHET AND PAWL 
ADJUSTMENT

See Figure 6-15 for following procedure.

General

This topic applies only to the ratchet and pawl provided on
the right rear drum (Drum 2 used for boom hoist on MAX-ER
2000).

The pawl limit switch must be properly adjusted to ensure
proper operation of the drum.

When DRUM 2 PARK switch is ON, Drum 2 park brake is
applied, the control handle is disabled, and the pawl is
engaged. When the pawl is engaged, the limit switch closes
the electric circuit to the crane’s programmable controller.
This action prevents Drum 2 from being operated in either
direction. Drum 3 is operable when Drum 2 is parked.

When DRUM 2 PARK switch is OFF, Drum 2 park brake is
released, the control handle is enabled, and pawl is
disengaged. When the pawl is disengaged, the limit switch
opens the electric circuit to the crane’s programmable
controller. This action allows Drum 2 to be operated in either
direction as long as Drum 3 is parked.

If the operator attempts to operate either drum (2 or 3) when
the other drum is not parked, the operating limit alert will
come on and FUNCTON NOT PARKED will appear on the
digital display.

The pawl limit switch is factory set and does not require
periodic adjustment. The limit switch must be adjusted if
parts are replaced and checked if the drum is not operating
properly.

Limit Switch Adjustment

1.

Loosen screw so limit switch lever is free to rotate on
shaft.

2.

Disengage Drum 2 pawl by toggling DRUM 2 PARK
switch to OFF. It may be necessary to hoist slightly
before pawl will disengage ratchet.

3.

Rotate lever and hold it so roller is against pawl.

4.

Turn limit switch shaft — not the lever  —
COUNTERCLOCKWISE until limit switch clicks open
and hold.

5.

Make sure roller is against pawl and securely tighten
screw in lever to lock adjustment.

6.

Check for proper operation:

•

Engage Drum 2 pawl by toggling DRUM 2 PARK switch
to ON. Try to operate Drum 2. Drum 2 should not
op era te in e ither d ire ction . Drum 3  should be
operable.

•

Disengage Drum 2 pawl by toggling DRUM 2 PARK
switch to OFF. Toggle DRUM 3 PARK switch to ON. Try
to operate Drum 2. Drum 2 should operate in either
direction. Drum 3 should be inoperable.

7.

Readjust limit switch if required.

Return Spring

Adjust the eyebolt so the return spring has enough tension to
fully engage and hold the pawl against the ratchet.

WARNING

Moving Parts Hazard!

To make adjustments, engine must be running and drums
and pawl must be operated.

Avoid injury from moving machinery. Stay clear of drums
and pawl while either is being operated.

Maintain constant communication between operator and
adjuster so drums and pawl are not operated while
adjuster is in contact with parts.
