“别拉斯”型重型自卸车是比较贵重的汽车,在汽车运输企业的固定基金中占有很大的比例,减少它们在修理和技术保养过程中停留的时间是很大的经济储备。大型企业中,“别拉斯”型汽车停留一个小时损失达18～22卢布,它们用于技术保养中的费用约占运输成本的50％,而随着露天矿深度的增加(超过100米时),这个费用将是总成本的70％。为了进行技术保养和修理,就必须拆卸和安装个别的部件和总成。这些部件和总成有着较大的尺寸和重量,不可能用手工操作把它们拆下来。按着自卸车的总布置状况,采用通用的起重机械也不能拆下和装上它的全部总成。
The “Belas” heavy-duty dump truck is a more expensive car, which accounts for a large proportion of the fixed assets of the automobile transport enterprises. It is a great economic reserve to reduce the time it takes for them to be repaired and maintained. Large enterprises, “BELAS” type cars stop an hour loss of 18-22 rubles, they used for technical maintenance costs account for about 50% of transport costs, and with the depth of the open pit mine (more than 100 meters ), This fee will be 70% of the total cost. For technical maintenance and repair, individual parts and assemblies must be dismantled and installed. These components and assemblies have a large size and weight, it is impossible to remove them by hand. According to the general layout of the dump truck, using a common crane can not remove and install all of its assembly.
