Using The Underlift - NRC 30CS Operation And Maintenance Manual

3.8

Using the underlift

The underlift is used to tow another vehicle.
For safety purposes, the underlift must be hooked to the boom for transportation.
The following sections describe all underlift operations.
Do not drive the wrecker while the underlift is in the storage position (resting on the
storage pin).
3.8.1 Understanding the underlift movements
The underlift is attached to and supported from above by the boom. The underlift also has two
attached rollers, one on each side, that roll inside the rails of the wrecker. The rollers act as the
underlift's fulcrum. Move the underlift and stinger by moving the boom as follows:
Extend the boom to tilt the underlift stinger toward the ground. This will position the stinger
l
under the vehicle to be towed.
Retract the boom to tilt the underlift stinger away from the ground. This will lift the vehicle
l
to be towed.
Raise the boom to raise the whole underlift. This will raise the vehicle that you are towing.
l
Lower the boom to lower the whole underlift. This will lower the vehicle that you are towing.
