Do you know what conditions are required for the use of small concrete mixer? First, let's talk about whether the driver's license of small concrete mixer is required. B2 certificate is required to drive a concrete mixer. If you have a work permit, you can go to the place where your driving permit is located!
混凝土搅拌车车是一种车辆，并不是所有会开车的司机都会开混凝土搅拌车，如果操作不当会引起翻车、液压泵、马达、减速机过快磨损甚出现严重后果。
Concrete mixer truck is a kind of vehicle. Not all drivers who can drive will drive concrete mixer truck. If it is not operated properly, it will cause rollover, excessive wear of hydraulic pump, motor and reducer, and even serious consequences.
小型搅拌车启动前，应把搅拌筒操作手柄放在“停止”位置。混凝土搅拌车起动发动机后，应使搅拌筒在低速下转动10分钟左右，使液压油温升到20℃以上后方可工作。
Before starting the small mixer, put the operating handle of the mixing drum at the "stop" position. After starting the engine of the concrete mixer truck, the mixing drum shall rotate at low speed for about 10 minutes to raise the hydraulic oil temperature to more than 20 ℃.
混凝土搅拌车在露天停放时，装料前应将搅拌筒反转，将积水和杂物排出，以保证混凝土的质量。混凝土搅拌车在运输混凝土时，要保证滑斗放置牢固，防止因松动造成摆动，在行进中打伤行人或影响其它车辆正常运行。
When the concrete mixer truck is parked in the open air, the mixing drum shall be reversed before loading to discharge the ponding and sundries, so as to ensure the quality of concrete. When transporting concrete, the concrete mixer shall ensure that the sliding bucket is firmly placed to prevent swinging due to looseness, injuring pedestrians or affecting the normal operation of other vehicles.
小型土搅拌车装运搅拌好的混凝土时，搅拌筒转速为2-10转/分，在运输过程中，平坦路面上搅拌筒转速保证在2-3转/分，行驶在侧倾坡度大于50的路面，或左右晃动较大的路面时，应停止搅拌旋转，待路况好转后再恢复搅拌旋转。
When the small soil mixer truck loads the mixed concrete, the speed of the mixing drum is 2-10 R / min. during transportation, the speed of the mixing drum on the flat road shall be 2-3 R / min. when driving on the road with a roll gradient greater than 50 or the road with large shaking left and right, the mixing and rotation shall be stopped, and the mixing and rotation shall be resumed after the road conditions improve.
搅拌车的混凝土搅拌时间不能超过搅拌站规定的时间。运送混凝土途中，搅拌筒不得长时间停转，以防混凝土产生离析现象。司机应时常观察混凝土情况，发现异常及时通报调度室，申请做出处理。搅拌车车内装有混凝土时，在现场停滞时间不得超过1小时，如超时应立即要求现场负责人给予及时处理。
The concrete mixing time of the mixer truck shall not exceed the time specified in the mixing plant. During the transportation of concrete, the mixing drum shall not stop for a long time to prevent segregation of concrete. The driver shall always observe the concrete condition, timely report any abnormality to the dispatching room and apply for handling. When the mixer truck is loaded with concrete, the standstill time on the site shall not exceed 1 hour. In case of overtime, the person in charge of the site shall be required to deal with it in time.
搅拌车运送混凝土塌落度不得低于8cm。从混凝土入罐到排出，气温高时不得超过2小时须排出，阴雨天气温度低时，不得超过2.5小时。搅拌车在排出混凝土之前，应使搅拌筒在10-12转/分的转速下转动1分钟，再进行排料。
The slump of concrete transported by mixer truck shall not be less than 8cm. The concrete shall not be discharged for more than 2 hours when the temperature is high, and not more than 2.5 hours when the temperature is low in cloudy and rainy weather. Before discharging concrete, the mixer shall rotate the mixing drum at the speed of 10-12 rpm for 1 minute before discharging.
