产品概述
技术参数

◆ 拥有可靠的系统与强劲的动力及可拓展性履带，加长的履带长度，增加履带展开后宽度，提高钻机的稳定性，上车平台双减速机驱动，解决制动难题，适应各种复杂工况，具有经济、高效、环保、稳定等多重特点。

Possessing reliable system, strong power and expansible tracks. Lengthened tracks improve stability of drill rig. Up structure is driven by dual reduction gears, which eliminates braking problems. The system is capable of adapting all complicated working conditions, with advantages such as economical, efficient, environmental-friendly, stable, etc.

◆ 选择Cummins QSM11-C428柴油发动机。通过改善燃烧过程，使该发动机油耗降低，最大功率428马力，即319KW。主要部件改进：凸轮轴、活塞、喷油器、废气放气阀涡轮增压器、滤清器；改进曲轴箱呼吸系统、机油泵带衬套；改进耐磨性以延长保养周期。

Cummins QSM11-C428 diesel engine is selected. By altering combustion processes, fuel consumption of this engine is reduced, with maximum power of 428 bhp, which is 319KW. Improvement of main components: camshaft, piston, oil atomizer, turbocharger for waste gas release valve, filter; improved crankcase breathing system, fit machine oil pump with lining; improve abrasive resistance to extend maintenance cycle.

◆ 主卷扬被设计在钻机的回转平台内，采用力士乐进口的减速机与马达，可靠性高，维护成本低,钻机的稳定性好；钢丝绳的直径36毫米，钢丝绳工作在卷筒的第一层，成倍地提高钢丝绳的使用寿命，降低客户的维护成本，同时，增加的落地保护功能，最大程度的延长了主卷扬的使用寿命。

Main winching device is built in rotatory platform, adopting imported Rexroth reducer and motor, featuring high stability, low maintenance costs and great stability of drill; steel cable diameter is 36 mm, operating on the first layer of reel drum, multiplying service life of steel cable, reducing customers' maintenance costs. Falling protection feature is also added to improve service life of main winching device.
