產(chǎn)品介紹
主卷揚布置在桅桿的下部，十分便于觀察走繩；采用雙折線繩槽卷筒，使各層之間的負荷均勻分布，大大延長了鋼絲繩的使用壽命，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.
液壓系統(tǒng)使用*的負載反饋技術(shù)，可使流量按需分配到系統(tǒng)各個工作裝置，實現(xiàn)各種工況下的匹配，泵、馬達、閥、油管及管接頭均采用進口產(chǎn)品，確保高可靠性。
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底盤和上車，履帶間距在3000-4300mm之間調(diào)整，將卡特配重后移，增加配重重量，提高整機的穩(wěn)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.
采用新材料加強型桅桿結(jié)構(gòu)，結(jié)合合理施工工法，可強勁高效入巖。
Using new materials to enhance the mast structure, it can drill into rock efficiently by adopting a reasonable construction method.
