Explained In photovoltaic project construction, the stable operation of PV pile driving equipment directly affects project quality and progress. This article compiles the top 10 frequently asked questions about PV pile driving equipment, with professional answers and practical suggestions from the technical team, helping you efficiently advance construction.

Question 1: What if the verticality deviation of PV pile driving equipment exceeds 3° during piling? 

Answer: A deviation exceeding 3° is usually caused by equipment positioning errors, foundation settlement, or unstable hydraulic pressure.

Practical Suggestions:

(1) Calibrate the sliding guide frame inclination angle to within ±1° using a level;

(2) Check if the hydraulic system pressure meets standards (e.g., 22MPa for Hengwang equipment);

(3) Lay steel plates on soft ground to reduce settlement.

Question 2: What is the maintenance cycle for PV pile driving equipment? What should be checked daily? 

Answer: Regular full maintenance is recommended every 200 hours, with daily checks focusing on key components affecting equipment lifespan.

Practical Suggestions:

(1) Daily checks: Track tightness and hydraulic pipeline leaks;

(2) Every 50 hours: Clean the air filter and inspect drill rod wear;

(3) Every 200 hours: Replace hydraulic oil filters. Wear-resistant parts require heat treatment maintenance (Hengwang’s wear-resistant parts undergo professional heat treatment).

Question 3: Do different pile materials have different requirements for PV pile driving equipment?

Answer: Steel pipe piles and precast piles have different characteristics, requiring PV pile driving equipment to adjust parameters accordingly.

Practical Suggestions:

(1) For steel pipe piles: Use an impact frequency of 500-600 bpm and 75-85mm drill rods;

(2) For precast piles: Reduce frequency to 350-450 bpm and enable hydraulic buffering (Hengwang’s hydraulic system offers better stability);

(3) Pre-adjust pile positions using 360° frame rotation.

Question 4: How to prevent PV pile driving equipment from getting stuck in soft soil foundations? 

Answer: Soft soil has low bearing capacity, requiring optimized grounding and driving methods for PV pile driving equipment.

Practical Suggestions:

(1) Choose equipment with track shoe width ≥350mm (e.g., Hengwang HWL series);

(2) Lay gravel or steel plates to enhance ground bearing capacity;

(3) Keep driving speed ≤3km/h and avoid sudden stops/turns.

Question 5: How to reduce fuel consumption per pile if PV pile driving equipment uses too much fuel? 

Answer: High fuel consumption is often due to mismatched power or inefficient processes, which can be optimized using PV pile driving equipment features.

Practical Suggestions:

(1) Adjust power based on pile height (85kw is sufficient for 3m piles);

(2) Pre-position piles to reduce idling, completing 3-5 consecutive piles per movement;

(3) Hengwang’s hydraulic system consumes 15% less energy than industry averages, making it a priority choice.

Question 6: What to do if PV pile driving equipment gets "stuck" during piling? 

Answer: Sticking is usually caused by uneven geology or mismatched drill rods, solvable with PV pile driving equipment functions.

Practical Suggestions:

(1) Stop impacting and use reverse rotation or 360° frame rotation for adjustment;

(2) Ensure drill rod diameter is 5-10mm smaller than the pile hole;

(3) Switch to spiral drilling mode in hard geology.

Question 7: What is the service life of PV pile driving equipment? How to extend it? 

Answer: High-quality PV pile driving equipment has a design life of 8-10 years, with actual lifespan depending on maintenance and operation.

Practical Suggestions:

(1) Conduct overall stress testing every 500 hours (Hengwang’s frames undergo stress relief treatment);

(2) Avoid operation in extreme temperatures; preheat the hydraulic system in low temperatures;

(3) Replace with original accessories (Hengwang provides a "four-dimensional integration" accessory supply system).

Question 8: How to ensure safe movement of PV pile driving equipment in mountainous projects? 

Answer: Mountainous areas have steep slopes, requiring PV pile driving equipment to have stability and adjustment functions.

Practical Suggestions:

(1) Choose equipment with ±5° adjustable guide frames (supported by all Hengwang models);

(2) Inspect tracks and brakes, limiting climbing angles to ≤15°;

(3) Move in segments, check levelness regularly, and use remote control in dangerous sections.

Question 9: What certifications are required for PV pile driving equipment exported to Europe?

Answer: Europe has strict safety and environmental requirements for PV pile driving equipment.

Practical Suggestions: Certifications such as CE (noise ≤75dB) and German TUV are required. Hengwang’s equipment has obtained multiple international certifications, ensuring compliance for exports.

Question 10: How to handle hydraulic oil leaks in PV pile driving equipment emergently?

Answer: Leaks are often caused by loose joints or aging seals, requiring immediate handling to protect PV pile driving equipment.

Practical Suggestions:

(1) Stop operation, release pressure, tighten joints or replace spare seals (Hengwang’s after-sales service provides common accessories);

(2) Operate under reduced load and contact maintenance promptly.
