◎运送混凝土途中,搅拌筒不得停转,应该保持罐体转速在每分钟2-3转,以防混凝土产生初凝及离析现象;
During the transportation of concrete, the mixing drum shall not stop running, and the rotation speed of the tank body shall be kept at 2-3 revolutions per minute to prevent the initial setting and segregation of concrete;
◎当搅拌筒的旋向在正转与反转间切换时,须先将操纵手柄放至中间位置,待搅拌筒停转后,在切换搅拌筒的旋向;
When the rotation direction of the mixing drum is switched between forward rotation and reverse rotation, put the control handle to the middle position first, and then switch the rotation direction of the mixing drum after the mixing drum stops rotating;
◎液压系统为车辆的关键零部件,其工作压力不得随意调整,且需要按照使用说明书的要求定期更换液压油,油品牌号应符合相应的规定;
The hydraulic system is the key part of the vehicle, its working pressure shall not be adjusted at will, and the hydraulic oil shall be changed regularly according to the requirements of the operation manual, and the oil brand number shall meet the corresponding regulations;
◎在混凝土搅拌车车辆运输过程中,所装载混凝土的方量不能超过允许载重量。超载不仅会造成车辆的加速磨损,且对行驶安全造成严重影响;

In the process of transportation of concrete mixer vehicles, the volume of concrete loaded shall not exceed the allowable load. Overload will not only cause accelerated wear of vehicles, but also have a serious impact on driving safety;
◎混凝土搅拌车每天工作结束后,司机应负责向搅拌筒内注入清水并高速(12-14转/分)旋转5-10分钟,然后将水排去,以保障筒内清洁。用高压水清洗搅拌筒各个部分时,应注意避开电器元件和润滑部位;
After the concrete mixer works every day, the driver shall be responsible for injecting clear water into the mixing drum and rotating it at high speed (12-14 RPM) for 5-10 minutes, and then draining the water to ensure the cleanness of the drum. When cleaning all parts of the mixing drum with high-pressure water, pay attention to avoid electrical components and lubricating parts;
◎应定期检查减速机与前机架、减速机与罐体、副车架与底盘以及托轮与后机架等部位的连接螺栓松紧情况,务必保持各部位的螺栓拧紧力矩符合规定要求。且需按规定要求在混凝土搅拌车润滑部位添加润滑脂;
Regularly check the tightness of the connecting bolts between the reducer and the front frame, reducer and tank body, subframe and chassis, as well as between the idler and the rear frame, and make sure that the tightening torque of the bolts at each part meets the requirements. The lubricating grease shall be added to the lubricating part of the concrete mixer according to the specified requirements;
◎混凝土搅拌车车辆在露天停放一段时间后,装料前应先将搅拌筒反转,使筒内的积水和杂物排出。装料前,较好先向筒内加注少量水,并加速搅拌后卸出,以防止粘料。装料时可根据混凝土的塌落度的情况适当的增加罐体转速。
After the concrete mixer truck is parked in the open air for a period of time, the mixing drum shall be reversed before loading to drain the water and sundries in the drum. Before loading, it is better to fill a small amount of water into the cylinder, and speed up the mixing before unloading to prevent sticking. When loading, the rotation speed of the tank can be increased appropriately according to the slump of the concrete.
