Features

It is sure that XR450E is the class of machine heavily demanded in projects of railways, highways and high-rise buildings, which require deep foundation in hard formation. In the job site, XR450E could take 16 hours to drill a shaft of 2m diameter and 93m depth.
(1)XR450E is installed with a powerful engine of 399KW, the rotary drive of 450 kN.m torque, main winch of 520KN maximum lifting force at 70m/min speed, and crowd piston of 400KN push-down force.
(2)With six elements of Kelly bar, this machine can reach max depth of 114m. This heavy equipment is capable of handling with all drilling difficulties in the field.
(3)To ensure reliable performance and global service backup, most parts and components of the manufacturer sources from top international brands. Also the rotary drive works in the speed range of 7-25rpm.
(4)And lots of intelligent functions are applied to the machine, like cruise-drilling, auto-adjustment of push-down force, self-adjustment of heat exchanger, down-the-hole sensor, and 12-inch touch screen.
(5)Equipped with the smart designs, XR450E is quite operation-friendly, which includes quick-connection parallelogram cylinders, chases pushup cylinders, cat head cylinders and all lift-up locks.

Jobsite Application

In a highway project that connects Ningbo and Hangzhou, XR450E finished drilling a shaft of 2.8m diameter and 90meters within 24hours without stopping.
Also, in a testing field, XR450E achieved an impressive performance by extracting a piece of limestone of 1.5m(59in)OD, 1.75m(69in) height and over 60Mpa (8,702psi) hardness, only within half an hour.
