由装载机自行作装料称重,虽已属可能,但由于所用多数称重装置通常必须按每一专用装载机类型进行设计,故其成本较高。同时,由于所用方法不能保证长期可靠性,因此维修工作量大、费用高。为克服这些缺点,英国 Volvo BM 公司研制出一种称之为“微型载荷仪”的称重/累计装置。这种装置安装在装载机的液压系统内,它是适用于各种前端式装载机的标准称重和累计装置,主要特点如图所示,操作顺序如下:
It is possible, though it is already possible, for the loader to charge and weigh itself, but most of the weighing devices used have to be designed on a per-loader basis and are therefore more costly. At the same time, due to the method used can not guarantee long-term reliability, so maintenance workload, high cost. To overcome these shortcomings, the British company Volvo BM has developed a so-called “micro-load cell” weighing / totaling device. Installed in the loader’s hydraulic system, this unit is a standard weighing and accumulating unit for a wide range of front-end loaders. The main features are shown in the following figure. The sequence of operations is as follows:
