Rotary Drilling Rigs Soil Investigation Drilling Rig XR320D for Foundation Construction Work
Rotary Drilling Rig widely used in boring operation of bored concrete pile in foundation engineering of highway, railways, bridges, ports, docks and high-rise buildings. It adopts dedicated hydraulic retractable crawler chassis and heavy slewing bearing and has high stability. It adopts the luffing mechanism of large triangle form to ensure the stability of construction of big holes and deep piles in hard formation. It adopts the front-located single-rope main winch structure to greatly prolong the service life of steel wire rope and lower the use cost. According to specific working conditions, the users can select a corresponding gear of the Cummins turbo-supercharged engine with three gears, getting the drilling rig working as three engines. Unit head can switch between Normal Mode and Rock Cracking Mode which are applicable for soil and rock excavation respectively, improving the efficiency; Winch pressurization and sleeve drive are both available for selection to meet users' various demands. It is equipped with a centralized lubrication system as standard configuration; maintenance is easier. The complete machine has passed CE certification of TüV Rheinland group.
