Highlights
1. Full dimension flat-head cab for chassis, all covered walking surface, double H-type outriggers and a fifth jack are available, as well as 360 degree; Operation of boom, power system with various options.
2. It has the longest boom compared to the same class crane boom. Five-section boom of oval cross-section with special sliders, aligning device and high-tension steel plates contribute to smooth telescoping, reliable alignment, light boom weight and strong lifting capacity.
3. Bi-part jib, comprising one lattice section and one box section.
4. Double cylinder plus ropes for boom telescoping. Thick cable and bearing are imported parts and have reliable performance.
5. Hydraulic transmission for both superstructure and chassis. Each mechanism speed can be regulated steplessly, so smooth movement and easy operation can be gained.
6. Main and auxiliary winch systems can get oil supplied by single pump or double pump. The high efficiency motor of variable displacement has the features of lower speed with heavy load and higher speed with light load.
7. Slewing system with planetary reducer and constant closed-type brake has free sliding function. Straight-tooth slewing bearing activated by a motor and a buffer valve fitted in the hydraulic system contribute to free sliding and reliable inching control.
8. Founding counterweight suspended highly in the rear of the machine makes more space for slewing operation (standard counterweight of 4t +optional counterweight of 1t).
9. Equipped with perfect safety devices: Load moment indicator (LMI), hoist limit switch, outrigger pinning device and electric level gauge. And illuminators facilitate night operations.
10. Streamlined integrated operator's cab with full view, equipped with air-conditioner, roll-up sun shield, shock-absorbing adjustable seat, and soundproof and heat insulation.
11. Lower center of gravity, good stability, high travel speed and manoeuvreability facilitate fast job site transfer.
12. Excellent welding technology for structural members. Welding robot with advance process used for key welding make reliable quality products.
