The apparatus includes a hook block welded in position to the first structural member as well as a plate fastened to the second structural member with fasteners. The apparatus also includes a least one knuckle, wherein, the knuckle is pre-welded to the plate and overlaps and engages the hook block restricting movement of the first structural member relative to the second structural member.

Abstract: An electric power take-off system for mounting to a truck body to complement an existing power-take-off system powered by an internal combustion engine. The system includes a motor, a battery for providing electrical power to the motor, a fluid reservoir, a pump for pumping fluid through at least one hose from the fluid reservoir to at least one truck function and for return of the fluid to the reservoir. The system also includes a system interlock rendering inoperable the electric power-take-off system when the internal combustion engine is in operation and a motor controller in communication with the motor for controlling the power output of the motor. The system also includes a charging unit for charging of the battery and a data management system operable to collect data.
