JVR400D旋挖钻机-恒天九五重工有限公司手机版

详细介绍

主卷扬采用双马达、双减速、单层大卷筒配置，在保证提升力和速度前提下，钢丝绳的单层缠绕大大提高了钢丝绳使用寿命；导向滑轮架可完成两个自由度的动作，自动调整位置保证主卷钢丝绳通过，增强钢丝绳的使用寿命。

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.

施工钻进采用卷扬加压，加压力、起拔力达到44吨，加压行程可达14米，可实现多种工法施工。

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底盘和上车，履带中心距在2900-4500mm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。

Sourced CAT374D undercarriage and upper structure, the crawler could adjust between 2900mm and 4500mm. The readjusted counterweight improves the stability and reliability.

液压系统关键部分沿用卡特比勒液压系统主控回路、先导控制回路，使用了*的负载反馈技术，可使流量按需分配到系统各个工作装置，实现各种工况下的匹配。先导控制使操作更加灵活、安全、舒适、准确。系统独立散热。泵、马达、阀、油管及管接头采用进口产品，确保高可靠性。

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.
