On March 23, good news came from Yuchai Piling Industry (Changzhou) Co., Ltd., a subsidiary of Yuchai Heavy Industry Company Limited, that the first YCR260 full-electric-control rotary drilling rig independently developed by Yuchai Piling had succeeded in commissioning. For the first time, the technology of electrohydraulic proportional control was applied to a rotary drilling rig, filling a technical gap in the piling machinery industry and being up to advanced international standards.

YCR260 has innovatively accomplished the functions of adjusting performance by merely changing parameters and judging whether the working status of the machine is normal by acquiring electronic signals, thus changing pollution problems caused by repair of traditional hydraulic handles. Characteristics such as intelligentization, easy repair, environment friendliness and energy conservation can boost the operating efficiency, stability and reliability of the machine.
