    • A load measuring device for a construction machine includes a processing unit for acquiring signals indicative of cylinder pressure of front and rear suspension cylinders via pressure sensors and computing a weight value of a load put on a dump body of the construction machine. When the construction machine is traveling on a curvilinear route, the construction machine makes the output of the weight value ineffective. In particular, when the differential speed value between the rear wheels, received from a speed difference detector, is below a preset value, the arithmetic unit outputs a loading weight W computed by the processing unit, as final loading weight, and so that when the differential speed exceeds the preset value, the arithmetic unit makes ineffective the computed loading weight W as the final loading weight output.
    • 一种用于施工机械的负载测量装置,包括处理单元,用于通过压力传感器获取表示前后悬架气缸的气缸压力的信号,并计算施加在机器的倾卸体上的负载的重量值。 当施工机械以曲线方式行驶时,施工机械使重量值的输出无效。 具体而言,当从速度差检测器接收到的后轮之间的差速值低于预设值时,运算单元输出由处理单元计算出的装载重量W作为最终装载重量, 差速超过预设值时,运算单元将计算出的加载重量W无效作为最终装载重量输出。

    • In the course of largely tilting a vessel (3) backward of a vehicle body (2) by a hoist cylinder (10), occasionally the rear end portion of the vessel (3) runs into an embankment (4A) of dumped earth and sand. In consequence, a load by a vehicle weight to be applied to a rear suspension (8A) suspending the side of a rear wheel (8) of a vehicle is rapidly reduced. Therefore, an inner pressure (P) in the rear suspension (8A) detected by a pressure sensor (25) is rapidly lowered. In this case, a controller (27) controls the hoist cylinder (10) according to the inner pressure (P) in the rear suspension (8A) to stop an extension operation of the hoist cylinder (10). This can suppress occurrence of a state where the side of the rear wheel (8) of the vehicle body (2) is raised upward, that is, a jack-up state.
    • 在通过提升缸(10)使船体(3)向后倾斜的过程中,容器(3)的后端部分偶尔会流入倾倒的土壤和沙子的路堤(4A) 。 因此,施加到悬挂车辆的后轮(8)的侧面的后悬架(8A)的车辆重量的负载迅速减小。 因此,由压力传感器(25)检测到的后悬架(8A)中的内压(P)迅速下降。 在这种情况下,控制器(27)根据后悬架(8A)中的内压(P)控制起重汽缸(10),以停止提升气缸(10)的伸展操作。 这可以抑制车体(2)的后轮(8)的侧面向上升高的状态的发生,即起升状态。
