1. ZTC250R truck crane, which integrates Zoomlion's decades' experience in designing and manufacturing mobile cranes with advanced technologies, is a new generation of high-performance product developed to meet oversea market demands. Its performances such as lifting height, main boom length, working speed and lifting capacity, etc., have achieved advanced international level.
2. This product is a truck crane capable of full range slewing, installed with 5 telescopic boom sections and a manual hydraulic control system. The crane adopts a 3-axle special purpose chassis (6×4 drive) independently designed by Zoomlion. The full-width cab provides wide vision and simple decoration. The engine complies with the Euro III emission standard.
3. The latest directional control valve and hydraulic control device installed in the crane's hydraulic system ensure that each executive mechanism makes full use of its working capability, therefore system reliability and safety are improved. The safety devices such as relief valve, balance valve, hydraulic lock and brake valve fitted in hydraulic system prevent the accidents caused by overloaded oil lines and oil pipe ruptures.
4. Safety devices, including a load moment limiter installed in the crane, together with the complete lighting system, ensure driver's safety during operation and are convenient for crane operations at night.
5. This crane has a novel style which makes it beautiful in contour, in lines and in color.
