详细介绍

充分开发利用卡特底盘*的增压功能，对于极限工况条件下将系统压力提升到36MPa，从而使动力头扭矩和主卷扬提升力增大，实现比其他厂家同档位机型入岩能力更强，提升力更大；动力头多档控制，可满足多种工况的需求，提高施工效率的同时也达到节能减排的目的；增加动力头与主卷复合动作，有效提高施工效率。

Fully developing and taking advantage of turbocharged feature of Caterpillar Undercarriage which in limited conditions can increase the system pressure up to 36MPA, so that makes power head maximum torque and main winch maximum lifting capacity increased which also makes embedding and lifting ability more powerful compared with other companiessame-level drilling rig; Power head can be controlled well with multifold gears which can satisfy different construction condition, also improve construction efficiency, conserve energy and reduce emission; Increasing composite action for power head and main winch, effectively improving the efficiency of construction.

主卷后置，大滚筒单层钢丝绳，有效提高钢丝绳使用寿命;液压系统增加二级缓冲（蓄能器），减小减速机和马达的冲击,从而提高减速和马达使用寿命及节能环保。

Main winch installing backwards and large roller with single steel wire rope improving the wire rope service life; Hydraulic system with increased the secondary buffer(accumulator) to reduce the impact of speed reducer and motor, thus improve the service life of speed reducer and motor and also can achieve the goal of energy conservation and environmental protection.
