主卷扬布置在桅杆的最下部,十分便于观察走绳;采用双折线绳槽卷筒,使各层之间的负荷均匀分布,大大延长了钢丝绳的使用寿命,提高施工安全性。
Main winch located at the bottom of the drilling mast which offer good angle foe checking line’s work. Unique design in the line roll could prolong the use life of the steel line and also enhance the construction safety.
液压系统使用先进的负载反馈技术,可使流量按需分配到系统各个工作装置,实现各种工况下的最佳匹配,泵、马达、阀、油管及管接头均采用进口产品,确保高可靠性。
Hydraulic system adopts advanced load-feedback technology. Realizing hydraulic liquidity allocate to different parts according to the operation demand. Top key parts guarantee high reliability, such as pump, motor, valve, pipe and joint come from international top brands.
CAT336D底盘和上车,履带间距在3000-4300mm之间调整,将卡特配重后移,增加配重重量,提高整机的稳定性和可靠性。
Configuring CAT336D undercarriage and up structure. The crawler could adjust between 3000mm and 4300mm. The customers could backward the counterweight and increase its weight also for improving the stability and reliability.
采用新材料加强型桅杆结构,结合合理施工工法,可强劲高效入岩。
Using new materials to enhance the mast structure, it can drill into rock efficiently by adopting a reasonable construction method.
