Hoist for vehicle with interchangeable body

A hoist system for raising and mounting an interchangeable vehicle body onto a vehicle chassis, comprising:

• a hoist frame comprising first and second parallel frame members, extending along a longitudinal axis of the hoist frame between an elevated end and a pivot end, for slidably, supporting the interchangeable vehicle body;
• a subframe comprising first and second parallel subframe members and having mounting portions on each of the subframe members, the mounting portions including a series of mounting holes for receiving bolts for fixedly connecting to the vehicle chassis;
• a pivotal connection for pivotally connecting the pivot end of the hoist frame to the subframe;
• a linkage for connecting the hoist frame to the subframe, wherein the linkage comprises a hinge joint member having an upper leaf member pivotally connected to a lower leaf member for raising the elevated end of the hoist frame, wherein the linkage further comprises a first pivot bar for moveably connecting the upper leaf member to the first and second parallel frame members of the hoist frame, and a second pivot bar for moveably connecting the lower leaf member to the first and second parallel subframe members;
• a plurality of connection brackets at bracket locations for securely bolting the first and second pivot bars to the subframe and the hoist frame, for engaging and supporting the linkage at respective positions along the subframe and the hoist frame, enabling a respective configuration of the hoist system;
• and
• a winch assembly, retained in the elevated end of the hoist frame and extending beyond the pivot end, for raising the interchangeable body onto the hoist frame.
