How to Protect Bulldozers in Humid Environments


With the arrival of spring, China's rainfall has increased and the characteristics of high humidity environment are prominent. Long-term operation of bulldozers in a high humidity environment is prone to a series of problems such as performance degradation, rust deterioration and short circuit, leading to frequent equipment failures and even affecting service life.


Based on an in-depth analysis of the impact of high humidity environment on bulldozers, bulldozer supplier HBXG has developed a series of bulldozer protection programs and measures to ensure smooth construction of bulldozers in high humidity areas and minimize the adverse effects brought by the environment.


Strengthen site management

In the high humidity environment, the management of bulldozer operation site should be rain-proof, moisture-proof and lightning-proof. Various electrical switches and distribution cabinets should be protected from rain and moisture. Low-voltage distribution room should be installed in accordance with the provisions of lightning protection devices.

Improve the mechanical parking environment. When choosing temporary parking site, try to stay away from gullies, rivers and steep cliffs. Compact the foundation, dig the surrounding drains, deal with the slope and clean up the surrounding weeds.

Pay attention to equipment safety management and control. Regularly check whether the lubricating oil and hydraulic oil temperature control device is sensitive, whether the monitoring device is effective, whether the torque limiter, limit switch, emergency brake switch and other safety protection devices are reliable, whether the brake and steering are good, and if hidden problems are found, eliminate them in time, and prohibit the equipment from operating with disease.

Pay attention to maintenance

In the high humidity environment, bulldozer operators and maintenance personnel should pay attention to the daily maintenance work, focusing on the maintenance of the hydraulic system and electrical system.


Hydraulic system

Regularly check whether the pipeline and radiator are leaking, whether the fan is working normally, and whether the amount and quality of hydraulic oil meet the requirements. Clean the hydraulic oil tank regularly to reduce internal pollution and maintain the heat dissipation capacity of the hydraulic oil tank.

Pay attention to the use of the same brand of hydraulic oil, timely replacement of contaminated hydraulic oil, regular replacement of the hydraulic oil filter, to ensure that the hydraulic oil pipeline is smooth and the oil is clean.


Electrical system

Regularly check whether the terminals are loose, and whether the wire ends and contacts are oxidized or ablated. Correctly adjust the generator regulator and properly reduce the charging current.


Clean the battery

The battery stakes and positive and negative cables should be firmly connected. The height of electrolyte should meet the requirements. Refill distilled water in time and keep the vent unblocked.

Special protection measures

In high humidity environment, the operator should dehumidify and maintain the bulldozer in time to prevent rain and airborne chemicals from entering the bulldozer. After running the equipment, maintenance work mainly wiping, tightening and lubrication should be carried out.

When dehumidifying the electrical components, focus on wiping the parts that are exposed, wet, and prone to water accumulation.

To overcome the adverse effects of high humidity on the crawler bulldozer, the construction site should be equipped with a rain shed and rain cover for the bulldozer. However, it is strictly forbidden to wrap it with plastic sheeting to avoid affecting its heat dissipation.



In general, the impact of high humidity environment on bulldozers is complex and multifaceted. As long as the implementation of the above protective measures according to the characteristics of high humidity environment, you can improve the adaptability of the bulldozer to high humidity environment, to ensure the normal use of the bulldozer.
