Construction machinery in the role or the process of moving, if a sudden failure, should be a simple repair to enable it to reliably travel or effect.
2, plugging
Construction machinery, will produce the oil spill, leakage and leakage phenomenon, emergency plugging, more suitable for long-term construction in the tunnel construction machinery because of the limited working space prone to hydraulic or diesel fuel tank due to collision lead to the failure of the leakage. Loose fittings and oil spills, the available random students equipped with tape at the thread wraps 3-5 laps, it will tighten.
3, change
The field of construction machinery, should be as much as possible with a number of wearing parts spare parts in order to make the emergency replacement. Such as diesel engine cooling water pump seals water seal wear and aging will lead to water pump leaks, replacement of the water to win the title pump will return to normal. Of course, hydraulic cylinders, hydraulic pumps, hydraulic valve, replacement seal repair, are more effective. Also, if replacement parts assembly is even more simple and convenient, such as replacement of diesel filter or hydraulic oil, oil filter.
4, tied
By cable, wire and wooden clubs sticking somewhere bolt breaking or slipping in construction machinery can not tighten the binding, and to temporarily restore the running state. Such as the air pressure of 74 excavator institutions damaged, the front axle has been unable to connect, off-road performance of the machine, so that the suspension hydraulic cylinder cannot latch.
5, demolition
Under the premise that does not affect the running of construction machinery, removable stretch out temporarily not damaged parts.
6, short-circuit
If a component in the construction machinery starting system or control circuit is damaged, can neither repair nor replacement of spare parts, such as the situation permits, they could be considered short-circuit phase, emergency use. But not long-term use, often due to short-circuit phase will increase the heat of the circuit, may be burned to the other circuit elements, to be qualified to be the immediate replacement of damaged components to prevent the emergence of new fault.
7, supplement
Low pressure hydraulic hoses damaged, other pipe can be used to restore the original length in order to facilitate the emergency repairs. Several parallel branch circuit of the hydraulic system, a certain failure, the inlet pipe can be removed and sealed with a plug; such other branch circuit can continue to work until the work is completed promptly repaired.
9, alternative
When certain parts of construction machinery is damaged it cannot work, available on board temporarily affect other parts of the work or make the best of manufactured components to replace, but this maintenance method of construction machinery performance recovery is poor. For example, small excavator or 6135 diesel engine fan belt in a short time available tape backpack instead of braid, etc.
