Ballast may be secured behind or integrated into the front bumper or wrecker body/subframe/chassis to meet laden front axle load requirements.

The underlift shall be capable of lifting all working loads from ground level to a minimum height of 10”. Vertical adjustment of the underlift shall be possible during other underlift operations. The underlift shall have tilt up / tilt down capabilities of a minimum ±8deg relative to the horizontal.

A means of allowing the operator to identify underlift boom extension and tilt shall be provided. If electronic position feedback is not incorporated, the retractable stages of the boom shall be marked in 6-inch intervals with numbering every 12-inch. If an overload protection system is not provided, a lookup table shall be furnished stating allowable underlift loading as a function of extension.

For Item 971 Remote control operation of the underlift shall include a level stop assist system to aid the driver in deploying the grid into a predetermined loading position by interrupting both the tilt down and boom down functions. The system shall allow further downward travel of the grid with a second activation of either function.

A safety device shall be provided to lock the underlift position while either stowed or in use.

3.3.4 Towing Capability

The towing load capability of the underlift and wrecker shall permit towing of the minimum load listed in the min requirements listing. The towing capability is defined as the maximum un-braked vehicle weight that can be towed without exceeding the wrecker chassis GVWR (for un-braked tow loads, GCWR=GVWR). The maximum allowed towed load limits without operational brakes on the towed vehicle shall be furnished in the supplied operating manuals.

3.3.5 Hydraulic Lifts (Jacks/Outriggers)

For Items 973, 974, 975, and 976, two hydraulically actuated lifts shall be provided and positioned at the outside-rear of the wrecker. For 975R, 976R, and 977R, forward mid, and rear side mounted outriggers shall be furnished. The lifts shall be capable of unloading (supporting) the rear bogie with a combined (gross) load capacity of 150% of the maximum allowable recovery boom load. Outriggers must function to stabilize the vehicle platform for lifting and recovery functions at side angles to the wrecker. Each lift/outrigger shall have a flat foot and a spade attachment rated for a minimum normal load equal to the vehicle’s GVWR. Wreckers with four lifts must be furnished with at least two universal fit spades.

3.3.6 Wrecker Body

The wrecker body shall be of either aluminum or composite construction. The chassis frame rails shall be the load bearing members during use of the recovery boom, underlift, or jacks (as applicable). The fasteners used to secure the body and subframe to the chassis frame shall be of constant torque (locking) type. U-bolts are not acceptable. The securing hardware shall be capable of withstanding 150% of the maximum anticipated load. The method used to attach the subframe to the chassis shall comply with the chassis manufacturer’s Body Builder Instructions for chassis supplied.

The body shall contain storage compartments for all supplied auxiliary equipment and room for operator accessories. All available area on both sides of and underneath the wrecker shall be utilized for storage. The tool compartments shall be isolated from the frame using elastomeric mounts. For all Items, a method of storing and securing the safety chains near the tailboard of the wrecker shall be furnished. The means used for securing each safety chain to the wrecker shall withstand a load in any direction greater than the breaking strength of the supplied chain.

For Items 972 and 973, a means of securing tow bar mounting brackets to the rear of the wrecker body shall be furnished. The mounting device shall be able to withstand a minimum of 150% of the rated working loads for the offered tow sling assembly without failure.

For Items 971 through 973, the wrecker body deck floor shall be polished aluminum diamond plate or equivalent.

For Items 972 through 977R, a tunnel compartment shall be provided in the front…
