產(chǎn)品介紹
主卷揚采用雙馬達、雙減速、單層大卷筒配置，在保證提升力和速度前提下，鋼絲繩的單層纏繞大大提高了鋼絲繩使用壽命；導向滑輪架可完成兩個自由度的動作，自動調(diào)整位置保證主卷鋼絲繩通過，增強鋼絲繩的使用壽命。
Main winch adopts duel motors, duel reducers, single roll big drum. Pilot pulley could guild the rope to the right position to make sure the ropes are rolling in single roll. All this could prolong the life of the rope while ensures the pulling force and pulling speed.
施工鉆進采用卷揚加壓，大加壓力、起拔力達到44噸，加壓行程大可達14米，可實現(xiàn)多種工法施工。
Winch press technique makes the crowd pull force reach 44T and its crowd stroke reach 14m. This design can meet many kinds of construction methods.
原CAT374D底盤和上車，履帶中心距在2900-4500mm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。
Sourced CAT374D undercarriage and upper structure, the crawler could adjust between 2900mm and 4500mm. The readjusted counterweight improves the stability and reliability.
液壓系統(tǒng)關(guān)鍵部分沿用卡特比勒液壓系統(tǒng)主控回路、先導控制回路，使用了*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。先導控制使操作更加靈活、安全、舒適、準確。系統(tǒng)獨立散熱。泵、馬達、閥、油管及管接頭采用進口產(chǎn)品，確保高可靠性。
Hydraulic system key parts are still using CAT main control returning and CAT pilot control returning system; it adopts loading reflex technique, this could configure the flow press to each device according to the demand, ensures the machine works perfect with the job. Pilot control makes the operation agility, safe, comfortable, precisely. The whole system adopted a individual coolant system. Pumps, motors, valves, hoses and joint are using the imported famous brand.
