A track hitching structure is for a wheeled crane and the wheeled crane, and includes a vehicle frame and a connecting cross beam. The first end of the connecting cross beam is connected with a track. The second end of the connecting cross beam is connected with the vehicle frame. The second end of the connecting cross beam is higher than the first end of the connecting cross beam. The vehicle frame is connected with the track by the connecting cross beam with one high end and one low end, so the long-distance force transfer from the track to the race of the vehicle frame can be handled, then the shortcomings of tedious structure, large size, large weight and the like of the connecting device caused by a horizontal connecting cross beam are avoided, and the reliability and the working performance of the entire crane are improved.

A boom of a wheeled loader or digger is pivoted about a horizontal axis in a fork. Yaw adjustment is provided by opposed taper plugs which constitute a spindle of the boom. The taper portions of the plugs are eccentric with respect to the bearing portions and may be rotationally adjusted to correct misalignment of the boom in yaw. A threaded fastener locks the taper plugs to the boom.

A utility vehicle is configured for use in emergency situations. The utility vehicle includes a base, a set of tracks, and a set of outriggers. The set of tracks is secured to the base configured to move the base through rough terrain. The set of outrigger is configured to be disposed in a stowed configuration and a deployed configuration. The outrigger is disposed above the deck level in the stowed configuration. The outrigger also remains outside the set of tracks in both the stowed configuration and the deployed configuration. The outrigger comprises an upper leg, a lower leg, and an actuator.

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.
