Further, in the above-mentioned case,
each telescopic cylinder can slightly swing up and down around the hinged trunnion or the hinged shaft connected with the movable tail car, so that additional bending moment brought to the oil cylinder due to uneven track is released.
Each telescopic cylinder can slightly rotate around the hinge shaft along with the coaxial rotating support, so that additional bending moment brought to the oil cylinder by the fact that one tail car is not parallel to the movable tail car is released.
Compared with the prior art, the utility model has the following advantages:
1. can be extended and retracted, so that the movable tail car can be positioned at two working positions.
