This drilling rig is the lowest tonnage Kelly bar rotary drilling rig. The overall structure of the drilling rig is compact and small, and it is mostly used for small engineering construction. The maximum drilling depth of the drilling rig is 15M with a drilling diameter of 450-1500MM. It can be used with a variety of drills for construction operations. It is suitable for sand and clay drilling and digging, and concrete surface drilling. The rig weighs between 15-17 tons and is equipped with a crawler chassis and a front dozer blade, which has a certain earthmoving construction capacity. Depending on the softness of the construction soil, an optional anti-sagging cylinder can be installed. The drill mast is equipped with an auxiliary hoist to help hoist the construction equipment. The drill rod is driven by a hydraulic power head, and the drilling speed is adjustable, which is suitable for different soil qualities. This rig has obtained CE, ISO, SGS and other quality management system certificates. For more products and company information, you are welcome to consult and negotiate.
