要約
(EN)
A wheel loader (1) is provided with a vehicle body (2), a boom (3), a bucket (4), a boom cylinder (9), a bucket cylinder (10), a boom angle detection sensor (46), a bucket angle detection sensor (47), and a boom-cylinder pressure sensor that detects the force received by the boom as lift force. The wheel loader (1) starts a tilting operation of the bucket (4) when predetermined conditions are met, and ends the tilting operation on the basis of the amount of increase in lift force from the point in time that the tiling operation was started.

(ZH)
轮式装载机(1)具备:车身(2)、动臂(3)、铲斗(4)、动臂油缸(9)、铲斗油缸(10)、动臂角度检测传感器(46)、铲斗角度检测传感器(47)、对作为动臂所受到的力的提升力进行检测的动臂油缸压力传感器。轮式装载机(1)在规定的条件成立时使铲斗(4)的倾转动作开始,并根据从倾转动作开始的时刻起提升力上升的量来使倾转动作结束。
