Maintenance of the telescopic arm of the hook arm garbage truck

Hook arm garbage truck telescopic arm maintenance: key details to extend service life

As the core equipment of the urban sanitation system, the telescopic arm of the hook arm garbage truck bears the heavy responsibility of lifting and transporting garbage bins. Its performance stability directly affects work efficiency and safety. Industry experts point out that through scientific maintenance and standardized operation, the service life of telescopic arms can be significantly improved and the failure rate can be reduced.

1、 Cleaning and maintenance: preventing and controlling hidden dangers from the source

The telescopic arm is exposed to complex environments for a long time, and its surface is prone to attachment of garbage residues, oil stains, and corrosive substances. If not cleaned in a timely manner, it may cause rust, blockage, and even hydraulic system failure. It is recommended to use the "three-stage cleaning method": first rinse the surface dirt with a high-pressure water gun, then use a soft bristled brush dipped in neutral cleaning agent to treat the welds and joints, and finally wipe them with a dry cloth and apply anti rust oil. Special attention should be paid to thoroughly removing snow and residual melting agents after winter homework.

2、 Lubrication management: precise guarantee of mechanical performance

Lubrication is the core part of the maintenance of telescopic arms. High temperature lithium based grease should be used to lubricate the slide, pin shaft, and bearings periodically in strict accordance with the equipment manual requirements. In winter, it is necessary to switch to low-temperature lubricating grease to avoid slow movement due to increased viscosity. Before each assignment, it is necessary to check the lubrication status. If the grease changes color or clumps, it should be replaced immediately. Suggest establishing a "lubrication calendar" to record the time and location of each maintenance, forming a traceable maintenance record.

3、 Dynamic monitoring: preventive maintenance system

Before driving every day, it is necessary to implement the "Five Check System":

（1）. Structural inspection: Observe whether the arm body of the detachable container garbage collector is bent or deformed, and whether there are cracks in the welding points;

（2）. Hydraulic inspection: Confirm that there is no leakage in the oil pipe and the oil level is at the standard scale;

（3）. Limit test: Verify the automatic locking function of the telescopic arm at the extreme position;

（4）. Electrical testing: Check if the sensor is securely connected to the control circuit;

（5）. Operation test: No load expansion and contraction for 3 times, monitor for any abnormal noise or jamming.

4、 Operation standard: Eliminate human damage

Improper operation is the main cause of telescopic arm failure. When doing homework, it is necessary to follow the "three no's principle":

-No overloading: Strictly operate according to the rated load, overloading will cause permanent deformation of the arm body;

-Do not act recklessly: Do not forcefully drag frozen or stuck boxes with telescopic arms;

-Negligence: After severe weather, it is necessary to conduct a comprehensive inspection of the surface of the arm for any accumulated water or ice.

5、 Professional Maintenance: Building a Technical Support Line

When the hook arm garbage truck experiences hydraulic oil leakage, inaccurate movement, or abnormal heating, it must be stopped immediately and the manufacturer's authorized repair point must be contacted. Unauthorized disassembly of hydraulic components or use of non original accessories is prohibited. It is recommended to conduct a comprehensive physical examination of the telescopic arm every quarter, including non-destructive testing and hydraulic system pressure testing, and promptly replace seals and pin shafts that have reached the wear limit.

conclusion

The health status of the telescopic arm is the cornerstone of efficient operation of environmental sanitation operations. By establishing standardized maintenance procedures, strengthening dynamic monitoring mechanisms, and enhancing awareness of operational norms, equipment downtime can be significantly reduced, and the service life can be extended by more than 30%. Each environmental sanitation unit should include the maintenance of the telescopic arm of the detachable garbage truck in the safety production assessment system, in order to finely manage and protect the "lifeline" of the urban environment.
