There are many reasons for the failure of the hydraulic braking system of the push rod in the corrugated guardrail pile driver. A single factor may lead to multiple failures, what failures will occur, and how to solve them will be introduced one by one. The hydraulic push rod brake failure of the corrugated guardrail pile driver requires regular lubrication and maintenance. Failure of the hydraulic brake of the pile driver's push rod. The failure of the hydraulic brake of the push rod in the corrugated guardrail pile driver requires consideration of the environmental conditions used when selecting the push rod's hardness and stiffness before installation and use. It can be assumed that the failure of the hydraulic brake of the push rod in the corrugated guardrail pile driver is likely due to the smaller set screws in the couplings, making them more prone to loosening. Measures should be taken by everyone to prevent them from loosening and falling off to avoid such failures.

Other hydraulic braking failures of the pile driver's push rod, such as the friction between the belt and the brake wheel, severe wear can reduce the braking torque or lead to failure in the absence of braking torque. However, if the corrugated guardrail pile driver can be installed, operated, and maintained according to regulations, the possibility of failures can be minimized.
