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:
l
Extend the boom to tilt the underlift stinger toward the ground. This will position the stinger
under the vehicle to be towed.
l
Retract the boom to tilt the underlift stinger away from the ground. This will lift the vehicle
to be towed.
l
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.

Towing another vehicle
If using the NRC Heavy duty tire lifts (bus brackets), use caution when installing
them onto the T-bar to prevent injury. Position yourself correctly while lifting heavy
objects.
