In the use of excavator pile drivers as auxiliary construction equipment, relying solely on the equipment often fails to achieve the desired results. In actual construction, mastering some necessary theoretical knowledge can greatly enhance the construction effect and is also an effective method for maintaining excavator pile drivers. In this regard, we share some common theoretical knowledge:

Break-in Period for New Pile Drivers: Newly installed pile drivers have a break-in period. During the first week of operation, it is recommended to change the gear oil within the first half to one full day of work. Then, change the gear oil every three days, resulting in three gear oil changes within the break-in week. After the break-in period, perform regular maintenance based on working hours, changing the gear oil every 200 working hours. This cycle can be adjusted according to different work intensities, and each oil change should include cleaning the magnetic filter.

Balancing Rigidity and Flexibility in Piling: Understanding how to balance rigidity and flexibility is crucial in piling. The more challenging the driving conditions, the more durable the equipment. When the machine reaches the marked position, higher driving speed leads to greater wear and tear. If the piling progress is slow, it is advisable to pull the pile out by about 1-2 meters at an appropriate time. The pile driver and excavator's power can then assist in driving the pile into the ground by 1-2 meters.

Reducing Wear During Piling: During piling, after reaching the marked position, default the template to open for 5 seconds to reduce wear on the template, shoulder rods (links), pins, and pin holes. When the pile driver pedal switch moves away from the marked position, residual vibration occurs due to the machine's inertia. In the clamped state, there is no gap between parts, thus reducing wear and improving the clamping effect. The best time to stop the vibration is when the pile driver ceases vibrating.

Dealing with Different Soil Textures: Since soil texture varies, with some being loose on the surface and harder underneath, encountering hard soil at a certain depth is common. Additionally, if the pile core is too long, the soil exerts increasing pressure on the core as it is driven deeper. Therefore, when driving to a certain depth, slow down the piling process, creating a pile that can be driven bidirectionally. This rational use yields better results.
