Figure 1-31. M1089 Underlift
d. M1089 Underlift. Vehicle model M1089 is equipped with a hydraulic underlift (1, Figure 1-31) component. The
underlift is used for towing a disabled vehicle. Stifflegs (2) are used to keep the M1089 vehicle stable during recovery
operations. The stinger (3) can be extended to position the crossbar (4) beneath the vehicle being recovered. The
crossbar is equipped with adapters which make it suitable for towing a wide range of vehicles. Two underlift cylinders
(5) control the height of the crossbar to allow the operator to tow a disabled vehicle with the front wheels off the ground.
All underlift functions are hydraulically controlled from the WRECKER CONTROL PANEL (6).
