Product Description

298kW Hydraulic Water Well Rotary Drilling Rig XR320D

XR320D 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.

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 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.
