Safety statement
Safety is no small matter. Kalmar always puts safety first. In the maintenance manual for locomotives delivered with new vehicles, it contains the unexpected situations and risks that may occur during the use, maintenance and repair of equipment under normal conditions to remind operators and The maintenance personnel take care to ensure that there is no risk of personal injury and equipment property damage during the work process.
What should be noticed in the operation and maintenance of equipment? First of all, to comply with local laws, safety regulations and regulations and safety instructions. Second, related work training and proper equipment and tool operation training are also indispensable; Again, the staff Always wear protective clothing and labor insurance supplies. Always be cautious. Finally, we should not ignore the chance of a fluke. We need to take appropriate measures to avoid injury. With these safety information, I hope everyone can be foolproof in their work.
Locomotive maintenance status
How can safety be ensured when the locomotive is repaired, maintained and needs to be fixed?
In stacker maintenance operations, we first need to pull up the hand parking brake to completely minimize the gantry and spreader, and ensure that the mast completely tilts forward, extinguish the engine, cut off the system power supply and disconnect the battery switch.
In the front crane maintenance operation, we first need to pull up the hand parking brake to allow the spreader to fully retract the boom and minimize it, extinguish the engine, cut off the system power supply and disconnect the battery switch.
Hydraulic and brake systems, pressure relief
The pressure relief of the locomotive hydraulic system in the maintenance state has the following three steps:
1. Open the battery main switch, and turn the start key to position I;
2. Repeatedly operating the aviation handle before and after;
3. Start the key to position 0, disconnect the battery switch.
The equipment that the spreader needs to be relieved of pressure includes DCT forklift and front crane: when the DCT forklift is depressurized, the main valve of the frame needs to be opened to connect the valve on the oil pipe;
The valve on the servo control valve must be opened when the pressure is discharged from the front. During the operation, the hydraulic oil may be incorrectly guided to other places, which may damage the precision filter element. Therefore, before starting the engine, make sure that the pressure relief valve is closed.
When the brake system releases pressure, open the valve on the pressure relief valve counterclockwise. While maintaining the pressure relief valve open during pressure relief, close the pressure relief valve clockwise until tightened.
The above is the safety information in the maintenance process of locomotives shared by Xie Hansheng and Xiao Bian, the product support division of Kalma South China. Please look forward to sharing safety information on oil products and fire explosions next week. c
