Mobile Crawler Drilling Rig Machine for Foundaion Construction XR320D
Technical Characteristics:
* 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 imported 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.
