High overall efficiency XR240 Rotary Drilling Rig

Power and efficiency upgrades

Strengthen the power based on XR220D, and improve the performance of power head and main winch by 20%; Isuzu engine has low oil consumption, many maintenance network points, suitable for soil layer, sandstone, basalt composite formation, and strong drilling capacity in hard rock.

Single-row rope long-term design

All the main and auxiliary winches are single-row ropes, and the service life of the wire rope is 2 – 4 times of that of the multi-layer winding type, greatly reducing rope change shutdown and reducing the cost of consumables.

Stable luffing structure

Double-arm parallelogram variable amplitude, 16% expanded support range, small shaking of the whole machine for large-aperture and deep-hole construction, more stable hole verticality, strong adaptability of high-precision pile foundation in urban area.

High-temperature stable hydraulic system

Independent high-power hydraulic oil radiator, fan automatic temperature control speed regulation, not easy to give high temperature alarm under 50 ℃+high temperature working condition in summer in the Middle East and South China, continuous operation without shutdown.

One-machine multi-power modularization

Quick switching of cylinder pressurization/winch pressurization; Optional pipe rolling machine, long screw and double power head, casing wall protection, CFG long screw pile, housing construction, bridge and municipal use.
