XCMG RT40E Rough-terrain Crane
Product Feature
RT40E is a type of high property price ratio rough-terrain crane of XCMG specially for the European market. RT40E is equipped with the two-axle loading chassis, which has two types of drive modes, four types of steering modes and backward-forward driving functions. It also has four sections of dodecagon main booms, H-type outrigger, fixed balance counterweight, as well as three working modes, including: hoisting with the support of outriggers, hoisting with the support of tire and hoisting when driving. It is widely used in oil field, mine, road and bridge construction, warehousing base and other construction sites.
Product Highlights:
Strong Power of Hoisting, Wide Range of Work
It has 32m main booms, 15m auxiliary booms, with the longest main booms and the highest comprehensive hoisting performance in the product of the same tonner.
Maneuvering and Flexible, Quick and Efficient
The max speed reaches 25km/h (38km/h for option) and the max gradeability is 55% and the min. turning radius is 5.7m. All these three factors make it flexible.
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 11,000km 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 one-way stabilized current control of parallel hydraulic pressure system reduces the loss of flow; 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. And the compounded suspension of leaf spring and hydraulic oil tank, and the self-recognition phased control of rotary cushion technology make the operation stability and comfortable;
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.
