Prepare the emergency drive hose, turn off the faulty concrete mixer, and remove the high-pressure oil pipe connector on the hydraulic motor.
Turn off the rescue vehicle, remove the high-pressure oil pipe of its hydraulic motor, and connect it with the corresponding connector on the faulty vehicle with emergency drive hose.
Start the rescue vehicle and turn its control handle to the discharging position, then the concrete in the failure vehicle will be discharged.
After the emergency drive, remove the drive hose and restore the two vehicles to their original state.
In order to control the rotation of the mixing drum, a wooden wedge is placed between the supporting wheel and the raceway of the concrete mixer truck;
Turn off the engine and loosen a high-pressure oil pipe of the hydraulic motor. The mixing drum can rotate freely. Control the rotation of the mixing drum to turn the maintenance hole to the lower part. Then open the maintenance hole and clean up the concrete in the drum.
After the concrete is discharged, the concrete mixer truck shall be restored to its original state.
As a sharp tool of new rural construction, small concrete mixing pump truck is widely praised for its flexibility and high efficiency. More and more people choose small concrete mixing pump truck to replace the traditional backward operation mode.
The service performance of the product, the smoothness and flexibility of each part of the action, chassis driving, turning diameter, approach angle, departure angle, minimum ground clearance, etc. meet the trafficability requirements, the fuel consumption rate and other economic indicators of the engine are reasonable, and the remote control operation is reliable and stable. For the weight of underframe and outrigger of Huilong machinery, the steel should be carbon steel (quenched and tempered steel sheet) with high strength and fine grain structure. The welding process requirements are very strict, otherwise there will be serious problems such as weld cracking. Small concrete mixing pump truck adopts full hydraulic technology, so it is necessary to consider whether all the hydraulic technology is advanced and how the hydraulic quality is. Because its power comes from the engine, in addition to the performance and quality of the engine, the performance, bearing capacity and quality of the chassis should also be considered.
