How to Improve Construction Efficiency for Solar PV Projects in the Philippines – Leili Machinery FAQ

Q1: How to solve the piling challenge on steep slopes in Philippine mountain solar projects?

A: On slopes exceeding 40 degrees, traditional heavy piling machinery cannot operate stably. Leili recommends lightweight crawler drilling rigs or handheld piling equipment, which are compact, highly adaptable, and capable of completing pile foundation work safely and precisely on complex slopes.

Q2: Which equipment is most efficient for the tuff and hard rock formations common in the Philippines?

A: For tuff and hard rock formations  common in the Philippines, Leili pneumatic-electric DTH drilling rigs and fully hydraulic crawler drilling rigs are the best choices. The pneumatic-electric DTH rig combines electric rotary drive with compressed air impact at 800-1200 BPM, efficiently drilling through hard rock. The fully hydraulic crawler rig features a high-torque power system with climbing ability of 30°-45°, operating efficiently in rock, gravel, sand, and mixed formations.

Q3: How to cope with the impact of the rainy season on construction progress in the Philippines?

A: During the rainy season in the Philippines, roads become muddy and the construction window is limited. Recommended measures: seize the dry season as the golden construction period and arrange the schedule reasonably to concentrate resources on pile foundation work; choose crawler-mounted equipment for better mobility on muddy roads; deploy multiple sets of equipment for parallel operations to shorten per-point construction time; and stock up on wearing parts in advance to avoid downtime due to parts shortages.

Q4: How can equipment be quickly mobilized to remote mountain areas in the Philippines where material transport is difficult?

A: Leili drilling rigs use lightweight, modular designs. Some models are detachable for split transport, suitable for narrow mountain roads and remote areas. Crawler-mounted equipment can self-propel on rough terrain, reducing dependence on large transport vehicles.
