Abstract: A detachable body securing mechanism having first and second clamp arms that rotate toward the inside of longitudinal support members of a detachable body to clamp down on the longitudinal support members is disclosed. The first and second clamp arms are rotatably coupled to respective first and second ends of an elongated frame of the securing mechanism. The securing mechanism further includes an actuable piston with a piston body coupled to the first clamp arm and a piston coupled to the second clamp arm. In certain implementations, extension of the piston rotates the first and second clamp arms away from each other and the elongated frame into a clamping configuration for securing the detachable body. Retraction of the piston rotates the first and second clamp arms toward each other and the elongated frame into a retracted configuration for releasing the detachable body.

Abstract: Disclosed herein is a hoist apparatus having a base frame, an arm, a hydraulic lift cylinder, and a contact fulcrum attached to the base frame. The arm has a base segment rotatably coupled to the base frame at a first joint, a middle segment rotatably coupled to the base segment at a second joint, and a coupling segment extendably coupled to the middle segment at a second arm joint, the coupling segment comprising a hook at a distal end of the coupling segment. The hydraulic lift cylinder is rotatably coupled at a first end to the base frame and rotatably coupled at a second end to the middle segment. In certain embodiments, the middle segment is contactable with the contact fulcrum during operation of the arm. Various implementations provide for a hoist apparatus that is disposable on a vehicle.
