Preparing The Wrecker For Optimal Performance - NRC 30CS Operation And Maintenance Manual

3.2

Preparing the wrecker for optimal performance

Position the wrecker on a flat, solid surface with the rear as close as possible to the load. Ensure
that you have sufficient reach and lifting capacity to safely proceed (see Section 1.2.7 Lifting
capacity).
If the load weight is close to the capacity of your wrecker, you can move the load and wrecker
closer together by removing the underlift from the wrecker chassis (see Section 3.8.5 Removing
the underlift from the wrecker). Moving the wrecker closer to the load allows you to retract the
boom and thereby increase the boom's lifting capacity.
Lifting a heavy load places significant weight on each jack leg. Ensure that the ground is solid
enough to prevent the jack legs from sinking.
Risk of tipping the wrecker. Ensure that ONLY the jack leg feet touch the ground. If
any other jack leg parts touch the ground, the wrecker will be unstable.
Decide whether to keep the underlift in place or remove it from the wrecker chassis and put it on
the ground. The boom has a limited field of movement when the underlift is attached. The
boom's hydraulic lift cylinders may come into contact with the top of the underlift stinger when it
is lowered and slid to the rear of the chassis. To learn how to remove the underlift, see Section
3.8.5 Removing the underlift from the wrecker.
Exercise caution when using the crane with the underlift, since any contact
between the boom and underlift can damage the equipment.
