HEAVY LOAD CARRYING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress meandering or displacement in a lateral direction by generating a friction between a part of a carrying base and a traveling road surface. SOLUTION: A plurality of airbags 12 are disposed at the bottom part side of a carrying base 10 connected to a driving device 14. Air is supplied to respective airbags 12 to inflate them, and the air is exhausted from the airbag 12 to form a thin air film between the airbag 12 and the floor 20. In the process where the carrying base 10 travels straight by a driving force of a driving wheel 22 in such a state that the carrying base is lifted with a storage stand 16 and a metal cask 18, when a torque is generated on the carrying base 10 around the driving wheel 22, straight travelability of an air pallet can be improved by negating the torque with an auxiliary wheel 24.
