A form in which the operation is locked, a form in which only the suspensions [71 and +71 at both ends in the longitudinal direction are locked, and a form in which only the suspensions at both ends in the longitudinal direction are locked, O and two pairs of suspensions in the middle in the longitudinal direction 1116 As shown in Figure 1
A configuration in which only the suspensions (7) at both ends in the front and rear directions are locked, and then the two pairs of suspensions (7) between the front and rear directions Φ are lowered and locked.
θ As shown in Fig. 7, after locking the operation of only the two pairs of suspensions (71) in the middle in the longitudinal direction, the suspension suspensions (7) and Φ at both ends in the longitudinal direction are lowered to lock the operation. ■As shown in Figure 8, the suspension jy, +, (only 71 pairs are lowered and locked) on either one of the 11H1 directions, ■As shown in Figure 9, the suspension on either the left or right side ( 7)・
・Various types, such as a form in which only the group is lowered and the operation is locked.
You can freely adopt the traveling type 11'.And when traveling on uneven terrain such as 1lljII,
By adopting the above-mentioned type MT, it is possible to reduce the movement of the vehicle body and prevent cargo from collapsing or falling, regardless of the unevenness of the road surface.It also provides a comfortable ride and is easy to ride on paved roads.

This can be done safely by suppressing the impact on the vehicle body due to load fluctuations that occur during demolition. In addition, when unloading a small load on rough ground, it is better to adopt the above @ shape tt, or to adopt the @ shape. Although the number of steps required for switching to the shape is small, the vehicle body can be stabilized, and when making an accompaniment turn, the above-mentioned O
Alternatively, by adopting the shape mt of ■, the turning can be done in a short half-way, and when traveling on flat land with a small weight loaded, by adopting the form 6 above, the turning resistance can be reduced. However, the vehicle body can be stabilized. Furthermore, in the case of driving on a slope, by adopting the form 11 of (■) above, the loading platform (
