Description

technical field

[0001] The invention relates to the technical field of railway maintenance equipment, in particular to a combined emergency reset system for large-scale railway maintenance machinery. Background technique

[0002] As an efficient railway maintenance equipment, large-scale railway maintenance machinery is widely used in railway maintenance operations. However, due to its complex structure and harsh operating conditions, it is inevitable that there will be failures during construction or operation. Sudden failures of the engine, electrical system, or hydraulic system make the operating device unable to return to the operating position, resulting in the inability of the large machine to operate commercially. If these faults are not dealt with in time, it may affect the operation of subsequent vehicles, and even lead to accidents. If the machine cannot be reset in time after falling off the road, it will also cause serious consequences. At present, auxiliary powe...
