Product Description

High Quality 2022 New 55t Rough-Terrain Crane Rt55e   

Product Highlights:

Technology from Europe, Performance in Leading Level

The product is developed by China and Germany with delicate design. The product has strong comprehensive lifting power with its 38.2m main doom and 17m auxiliary boom under the same boundary conditions.

Maneuvering and Flexible, Quick and Efficient

The max speed reaches 25km/h (37km/h for option) and the max gradeability is 55% and the min. turning radius is 5.7m. 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 Environment 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 flow distribution management technology makes the system efficient; and the gravity drop luffing system needs no extra power and save the oil consumption.

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.

The product is equipped with humanized climb ladder, maintenance access and control layout. And the product 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.
