<p><P>PROBLEM TO BE SOLVED: To provide a load attachable/detachable truck that facilitates the release of a toggle mechanism even if a large burden of a load loaded on a subframe is applied to the same. <P>SOLUTION: The load attachable/detachable truck is configured as follows. A front lifting machine 3a and a front toggle support machine 5a of a subframe 4 are arranged in the front of the subframe mounted on a rear frame 2 located at the rear of a vehicle body 1. A rear lifting machine 3b of the subframe is arranged in the rear of the subframe. The front/rear lifting machines 3a, 3b and the front toggle support machine 5a are connected to a synchronous hydraulic circuit and simultaneously operated in order to horizontally elevate and lower the subframe. When a load 6 is unloaded from a state that the load is loaded on the subframe, the load is lifted by the front/rear lifting machines immediately before a front toggle arm 11a and a front toggle link 14a of the front toggle support machine are in a folded state due to the release of a toggle mechanism from a rising state as being one straight line, and then, the toggle mechanism is released to put them in the folded state. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
