PROBLEM TO BE SOLVED: To propose a traction object trailer capable of easily making a trailer truck enter a place unable to secure a sufficient turning radius.SOLUTION: This traction object trailer 10 of the trailer truck 1 includes a load burden adjusting mechanism 30 at the rear end of its chassis 13, and a front side wheel shaft 16 and a rear side wheel shaft 17 are supported by the turning type frame 32 of this load burden adjusting mechanism 30. When turning the turning type frame 32 downward by a hydraulic cylinder 34, a burden rate of a trailer load by left-right front side rear wheels 16L and 16R of the front side wheel shaft 16 is increased more than left-right rear side rear wheels 17L and 17R of the rear side wheel shaft 17, and a state for turning a trailer vehicle body 11 in the lateral direction with the front side rear wheels 16L and 16R as the center, can be formed. Thus, the turning radius can be reduced more than a conventional turning radius, simplifying garaging operation to a narrow place. |
