Independent innovation, meticulously made, excellent design concept, to makes JVR300Z rotary drilling rig have a reliable system and strong power, which can adapt to various complicated conditions.Also it enjoys such multiple advantages as economic, efficient, environmental friendly and stable.

可拓展性履带，增加了履带的长度和展开后的宽度，提高钻机的稳定性；上车平台双减速机驱动，解决制动难题；优化配重布置并增加其重量，提高整机的稳定性和可靠性。

Self-extendable of the track, increased the track length and unfolded width, improves rig stability. Double reduction gear drives were adopted on the train platform to solve the braking problem. Weight optimization layout and increase the weight so that the stability and reliability of the machine can be improved.

液压元件采用力士乐元器件，保证液压系统的可靠性与稳定性；采用的设计理念，实现了流量的按需分配和精准控制，保障了传动效果；液压系统加入全过滤创新结构，极大地提高液压油的清洁度，使设备运行更可靠、更经济、更高效。

Hydraulic components adopt Rexroth components, ensuring the reliability and stability of hydraulic system. Using the international advanced design concepts realized the flow of distribution according to need and precise control, ensuring guarantying security transmission effect. Hydraulic system instilled full filtering structure innovation, greatly improving the cleanliness of hydraulic oil, making the equipment operation more reliable, more economical and more efficient.

动力头配置三马达、三减速机，满足钻机入岩大扭矩输出；针对入岩的工况，对动力头减震进行改进，引入减震结构和减震技术，经过现场试验，具有明显的减震效果。

The power head collocates with three motors and three reduction gears, satisfying the high torque output while drilling into the rock. According to the rock conditions, the power head shock absorption was improved, the damping structure and cushion technique were introduced, which has obvious damping effect through the field tests.
