Drilling holes in complex terrain During the construction of photovoltaic power stations, drilling pile foundations in complex terrains such as quarries and mountains is a big problem. Traditional Drilling Rigs are inconvenient to move and difficult to operate in areas with slopes exceeding 15°; manual drilling is inefficient, and only 3-5 pile holes can be completed per day in hard rock formations, which seriously slows down the progress of power station laying. Are you worried about construction delays and cost overruns caused by terrain restrictions? As a professional Excavator Converted Drilling Rig, the excavator converted photovoltaic drilling rig is flexible and powerful, and is specially designed for photovoltaic pile foundation drilling. Relying on the strong passability of the excavator chassis, it can move freely in complex terrains such as mountains and hills. With a special drill bit, the drilling efficiency of hard rock formations is increased to an average of 20-30 pe…
