JVR285HT旋挖钻机-恒天九五重工有限公司手机版

详细介绍

台以Cat345GC底盘生产的旋挖钻机。

The first rotary drilling rig produced by Cat345GC chassis in the world.

节能、智能、HT入岩显魅。

Energy saving, intelligent, HT entering - rock shows charm.

高效电控液压系统，自动调整液压功率各发动机转速来匹配所需工作条件，液压系统效率高、损耗小。

High efficiency electric control hydraulic system, automatically adjust the hydraulic power of each engine speed to match the required working conditions, high efficiency and low loss of the hydraulic system.

动力头多档控制，可满足多种工况的需求，施工高效，油耗低。

Power head multi-step control, can meet the requirements of various working conditions, high construction efficiency, low fuel consumption.

动力头与主卷复合动作，有效防止吸钻，提高施工效率。

The combined action of power head and main winch can effectively prevent absorption and improve working efficiency.

主卷扬防溜杆设计，通过匹配主卷扬换向阀、主卷扬平衡阀、主卷扬制动阀的启闭特性曲线，防止主卷扬装置失效，降低主卷扬溜杆发生概率，极大提高了主卷驱动系统的可靠性。

By matching the opening and closing characteristic curves of the main winch reversing valve, main winch balance valve and main winch brake valve, the design of the main winch anti-slide rod prevents the failure of the main winch device, reduces the probability of the main winch anti-slide rod, and greatly improves the reliability of the main winch drive system.

单层绳主卷扬，提升力大，钢丝绳寿命长。

Single layer rope main winch, with large lifting force and long life of wire rope.
