The invention discloses a crawler-type truck. The crawler-type truck comprises a truck body, a crawler walking mechanism, an auxiliary arm, walking auxiliary wheels and a blocking component. On one hand, the inclination angle of the truck body is adjusted on the basis that the stair angle is equal to the crawler belt angle during ladder climbing, so that the gravity center position is changed, meanwhile, the reverse force along the crawler belt is reduced to the maximum degree, a person can complete ladder climbing through cooperation with the crawler belt with small pulling force, labor is saved, and ladder climbing is safe; and on the other hand, when the truck walks on the ground, the inclined truck body is formed by the ground walking wheel sets and is in a balanced state in the horizontal direction, so that once an emergency or sudden working condition occurs, after a user slips out of the hand, the probability of truck sliding or turning over caused by truck pulling is low, the truck is safer, and meanwhile, only small pulling force is needed in the forward moving process.
本发明公开了履带式拉货车,其包括货车本体、履带行走机构、辅助臂、行走辅助轮、阻隔部件。本发明一方面爬梯时,基于楼梯角度和履带角度相等,进行调节货车本体倾斜角度,以改变重心位置,同时最大化的减少沿着履带反向的力,使得者只需要较小的拉力即可配合履带完成爬梯,非常省力且爬梯安全;另一方面地面行走时,由地面行走轮组形成倾斜货车本体在水平方向处于平衡状态,因此,一旦出现应急或突发工况,使用者脱手后,造成拉货车溜车或翻车的概率低,更安全,同时,前行中也只需要较小的拉力即可。
