Abstract: An aid system for a wrecker adapted to perform a lifting operation of an object having a weight, the wrecker comprising an extendable boom wherein the extendable boom is adapted to perform the lifting operation through which the wrecker either hauls or lifts the object. The aid system comprises: sensors mounted to the wrecker adapted to collect intrinsic information associated with the wrecker and extrinsic information on the interaction of the wrecker with the operating environment or on the environment in which the lifting operation is performed; a processing unit adapted to collect and process data collected from the sensors to generate dynamic load chart data; and a display for displaying a graphical representation based on the dynamic load chart data, comprising a depiction of the wrecker and of a limit of an operating condition of the wrecker.

Abstract: A drag winch assembly for a tow vehicle, such as a wrecker, that includes a slidable boom assembly. The drag winch assembly comprises a slidable support connected to the slidable boom assembly in slidable engagement with the main frame of the wrecker and a drag winch mounted on the slidable support. With this configuration, the slidable support is slidable between a first position corresponding to the frontmost position of the slidable boom assembly and a second position corresponding to the rearmost position of the slidable boom assembly, providing advantages existing winch assembly configurations.
