concrete mixer truck fault car handling

Caused by the mixing drum mixer can not turn generally have the following two conditions: (1) hydraulic system or engine failure; (2) motor malfunction. The treatment methods are as follows.
1) hydraulic system or engine failure treatment:
(1) Precast concrete plant tube manhole cover, rotating Song Mada on the high pressure hose fittings, the mixing drum rotating mixing drum manholes oblique, the concrete is discharged from the mixing tube manholes;
(2) the failure of the high pressure hose from the motor vehicle is removed, the rescue with a high-pressure hose connected to the other end of the pump on the rescue vehicles and emergency use of the return pipe terminating in a motor drain fault car mouth, back to the other end of the tubing in the rescue vehicle pump oil return port, stationary concrete batching plant vehicles to control the rotation of Drum fault car will concrete discharge.
After field tests we found that all of the tools in the production plants complete the case, using the second method takes about 1h, such as on site may take longer, so we recommend using the first method discharged concrete.
2) motor fails, the processing is relatively simple, can remove the rescue vehicles mounted on a motor vehicle failure, then all tubing connected, start rescue vehicles can be mixed with concrete barrel discharged.
In short, for the mixer, the failure should be promptly determine why the failure occurred, and take effective measures to mix concrete barrel discharged after troubleshooting.
