XCMG Official 70ton QY70K-I Truck Crane for Uzbekistan

1.  Full dimension flat-head cab for chassis, allcovered walking surface, double H-type outriggers and a fifth jack areavailable, as well as 360°ºoperation of boom, power system with various options.
2.  It has the longest boom compared to the sameclass 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 sectionand one box section.
4.  Double cylinder plus ropes for boomtelescoping. Thick cable and bearing are imported parts and have reliableperformance. 
5.  Hydraulic transmission for both superstructureand chassis. Each mechanism speed can be regulated steplessly, so smoothmovement and easy operation can be gained.
6.  Main and auxiliary winch systems can get oilsupplied by single pump or double pump. The high efficiency motor of variabledisplacement has the features of lower speed with heavy load and higher speedwith light load.
7.  Slewing system with planetary reducer andconstant closed-type brake has free sliding function. Straight-tooth slewingbearing activated by a motor and a buffer valve fitted in the hydraulic systemcontribute to free sliding and reliable inching control.
8.  Founding counterweight suspended highly in therear of the machine makes more space for slewing operation (standardcounterweight of 4t +optional counterweight of 1t).
9.  Equipped with perfect safety devices: loadmoment indicator (LMI), hoist limit switch, outrigger pinning device andelectric level gauge. And illuminators facilitate night operations.
10. Streamlined integrated operator’s cab with fullview, equipped with air-conditioner, roll-up sun shield, shock-absorbingadjustable seat, and soundproof and heat insulation.
11. Lower center of gravity, good stability, hightravel speed and manoeuvreability facilitate fast job site transfer.
12. Excellent welding technology for structuralmembers. Welding robot with advance process used for key welding make reliablequality products.
