Abstract
Mechanism to be added to existing two-wheeled dolly structures used for tng military shelter units from one geographical location to another. The add-on mechanism includes a motorized wheel unit attachable to the dolly structure to facilitate manipulation of the dolly structure into precise alignment with the shelter; the add-on mechanism further includes motor means for powering a hydraulic pump used to actuate certain lift cylinders on the dolly structure. The add-on mechanisms reduce the time expenditure required to hook the dolly to the shelter and raise same into a condition suitable for towing by a military truck.
