XCMG  Rotary Drilling Rig XR240E (Euro Stage IV)

As a multi-function machine, it can realize the quick switching of functions such as cylinder pressurization, crowd winch pressurization, oscillator, CFA, and dual power head. Meet more different construction needs.

The capacity of rotary drive and main winch is increased by 20% and the work efficiency is higher

The rotary drive can be equipped with a torque multiplier (optional).The casing drive torque is up to 360kN-m and the casing construction ability is stronger.

The main and auxiliary winches both adopt single-layer rope technology. The service life of the wire rope is 24 times longer than that of the multi-layer rope and the cost is lower.

The double jib parallelogram luffing mechanism has a large support angle and a 16% increase in the support range. The operation a more stable.

The hydraulic system adopts negative flow control technology which has a fast response and good control performance.

The independent high-power rate temperature-controlled hydraulic oil cooler is suitable for high-temperature construction and can adjust fan speed with temperature changes.


Intelligent control system can automatically adjust and display the verticality of mast, automatically slew and slag discharge, CFA model automatically lifting concrete pouring and pile type display. The system uses bus panel design to prevent misoperation.
