Product Feature
RT120E is a high-end model developed by XCMG and an experienced R&D institute in Europe, which has been approved by CE in Europe. The product is equipped with two-axle loading chassis and has two types of driving model, four types of turning models and back-and-forward driving function. The product has five sections of quadrangular great circle main doom, H-type outrigger as well as combined self-removal and installation counterweight. It has three types of operation models such as operation with the support of outrigger, operation with the support of tire and hanging when driving. It is widely used in oil field, mine, road and bridge construction, warehousing base and other construction sites.
Product Highlights:
Technology from Europe, Performance in Leading Level
The product is developed by China and Germany with delicate design. The product has strong lifting power with its 48m main doom and 20.6m auxiliary boom.
Maneuvering and Flexible, Quick and Efficient
The max speed reaches 25km/h (33km/h for option) and the max gradeability is 60% and the min. turning radius is 7.5m. All these three factors make it flexible.
The product is equipped with great power system, specialized cross-country pattern tire and skid resisting differential locking gear. All these three factors make it drive over all kinds of road easily.
Safe and Reliable, No Worry to Handle
The product is equipped with lifting protection control system in case of overload, over-retracting and over-stretching as well as exclusive technology in this field like rear axle-wheel automatic return-control system and safety-driving automatic protection system. All these elevate its safety performance largely.
The product is equipped with top features in this field, professional matching upgrading and systematic evaluation test. And it has passed test like driving 4,000km and 10,000 times hanging. Both ensure its reliability.
Economic and Environmental Protection, with Cost Saving
The product is equipped with optical matching power transmission system and torque converter with lockout function, which decrease the oil consumption over 20% at high speed.
The downward-gravity luffing system makes the product need no extra power. And the electrical variable power control decreases the comprehensive oil consumption by 15%.
Comfortable to Handle, Convenient to Operate
The product is equipped with full hydro-steering control system and automatic manual gear box, which make it easy to handle. It is equipped with turnover handling room, which presents a border view and makes it more comfortable to operate.
The product is equipped with humanized climb ladder, maintenance access and control layout. And it is equipped with professional man-machine engineering simulation analysis, exquisite man-machine interface and stand-alone fault diagnose function. It is comfortable to handle and convenient to operate.
