Excavator-Mounted Drilling rig Specifically engineered for pre-drilling operations in foundation piling, this system enables rapid switching between auger drilling and pneumatic impact drilling modes. It adapts to diverse construction requirements including:

• Building foundations (reinforced concrete pile preparation)

• Tunnel boring (rock bolt anchoring and blast hole drilling)

• Solar farm installations (PV pile hole drilling in complex terrain)

• Civil engineering (slope stabilization, micro-piling)

This system precisely adapts construction solutions to diverse geological conditions (rock/soil strata), while meeting mid-sized excavator modification requirements.

With the rapid expansion of the photovoltaic (PV) industry, PV power station construction has extended from flat plains to complex and fragmented sites, including mountains, hills, wastelands, abandoned mines, and agro-PV complementary areas. Traditional professional piling drills are bulky, difficult to transfer, costly, and poorly adaptable to complex terrains, failing to meet diversified construction demands. Against such industry pain points, the excavator-mounted drilling rig has become a core equipment for PV foundation drilling and bracket installation. Featuring multi-functionality, high flexibility, cost-effectiveness and strong working condition adaptability, it is applicable to both centralized and distributed PV projects, effectively helping construction projects improve efficiency, reduce costs and guarantee quality.

Product Definition

As a composite engineering device, the excavator-mounted drill is professionally and modularly refitted on the basis of standard excavators. Equipped with hydraulic power heads, drill rods, drill bits and intelligent control systems, it retains all original excavator functions such as walking and slewing, while adding high-precision drilling and piling capabilities. It requires no main engine replacement or major body modification, compatible with excavators of various tonnages. It perfectly adapts to dense hole arrangement, height differences and complex terrains in PV construction.

Core Advantages & Features

First, superior terrain adaptability. Adopting a crawler chassis and automatic slope leveling system, the drill operates stably on 30° steep slopes, muddy and rugged sites, solving the climbing and transfer limitations of traditional drills. It ensures a verticality error within ±1 cm for drilled holes, fully meeting PV foundation construction standards.

Second, powerful and stable drilling performance. Integrated with an optimized high-pressure hydraulic system, it delivers sufficient and stable torque to cope with common geological conditions such as loam, clay, sandstone and weathered rock. Fitted with DTH drilling tools, it can drill hard rock layers efficiently. It completes one standard hole in 15 minutes and supports continuous dense-hole operation, cutting fuel consumption by 15%-25% for long-term energy-saving benefits.

Third, dual-function and dual-mode design. It freely switches between excavation and drilling modes without dismantling modified parts. It undertakes PV foundation drilling in peak construction periods and handles site leveling, earthwork cleaning and slope anchoring in off-seasons, maximizing equipment utilization. It supports diesel and electric modes: diesel versions suit remote large-scale PV stations with 8+ hours of continuous operation, while electric versions feature low noise and zero emission for suburban and factory rooftop PV projects.

Fourth, flexible and efficient transfer. The integrated and compact structure enables independent on-site shifting, climbing and position adjustment without large trailers. It realizes rapid mobilization, construction and transfer, perfectly matching the scattered and multi-point construction characteristics of PV projects and greatly shortening the overall construction period.
