This jig is used to lift large commercial HVAC systems off and on of Stadler rail vehicles. It is designed to be used with a gantry crane.
Repairing a faulty HVAC unit on the roof of a vehicle can be timely. It is difficult to service a unit wearing fall protection, carrying tools and supplies up ladders. Quickly swapping a HVAC with a functional one reduces the entire vehicles down time. Then when time permits the unit can be serviced and placed back in the stockroom to be reissued the next time a unit fails.
The rig is attached with quick connect pins and requires no fasteners
