Chassis stacker

摘要

A chassis stacker having a first and a second vertical storage rack displaced from one another by a distance wide enough to accommodate a trailer chassis, and connected at a top end by a trolley rail support beam. A trolley is positioned on the trolley rail support beam, said trolley having an elevation system capable of raising and lowering a first and a second stabilizing beam that are suspended from the trolley and guided in their vertical motion by low-friction, storage-rack contact members attached at respective first and second ends of the elevating structure, said contact members in contact with an inner surface of the respective first and second vertical storage racks. A first and a second stabilizing-beam trolley is attached to the, respective, first and second stabilizing beams while a spreader containing a chassis-clamping mechanism extends between and attaches to the first and the second stabilizing beam trolley.

1. A chassis stacker comprised of:
a first and a second vertical storage rack, said first and second racks displaced from one another by a first distance wide enough to accommodate a trailer chassis and connected at a top end by a trolley rail support beam; a trolley positioned on the trolley rail support beam, said trolley having an elevation system capable of raising and lowering a first and a second stabilizing beam that are suspended from the trolley and guided in their vertical motion along the first and second vertical storage racks by low-friction, storage-rack contact members attached at respective first and second ends of each of the stabilizing beams, said low-friction, storage-rack contact members in contact with an inner surface of the respective first and second vertical storage racks as the low-friction, storage-rack contact members vertically move along the first and second vertical storage racks; a first and a second stabilizing-beam trolley attached to the, respective, first and second stabilizing beams such that the first and second stabilizing-beam trolleys move laterally along the respective first and second stabilizing beams; and a spreader extending between and attached to the first and the second stabilizing-beam trolleys such that the first and second stabilizing-beam trolleys move the spreader laterally between the first and second vertical storage racks, said spreader containing a chassis-clamping mechanism that forms a downward-facing portion of the spreader and the chassis-clamping mechanism is disposed below the first and second stabilizing beams, wherein the first and second stabilizing beams are above the trailer chassis when the chassis-clamping mechanism has engaged the trailer chassis.
