Oriemac 50 Tons Lifting Machine Hydraulic Mobile Truck Crane QY50KD
QY50KD Truck Crane Highlights:
1.Leading lifting performance and traveling performance
2.Mature and reliable double pump confluence technology, highest hoisting, elevating and telescoping efficiency in the industry
3.Improved reliability of radiation and electric systems, safer lifting and driving operation
4.Air-assisting shift gears bring more comfortable operation
5.New upgraded outline and humanized design, more comfortable driving operation
Overview:
The innovative jib system adopts embedded block, plug-in boom head and international advanced U section jib, which has excellent lifting performance and safe and reliable lifting work.
The unique stretch and retract technique avoids the bend of the core pipe and cylinder and the break of the boom caused by misoperation, improving the safety of the operations.
Eight patent techniques ensure the smooth, high efficiency and energy conservation of the lifting, rotation, and luffing systems.
Adopt the new hydraulic motor with big torque starting point, making the secondary lifting safer.
The torque limiter adopts colorful LCD display, realizing the intelligence of the failure diagnosis. The precision is ahead of the industry.
The humanity design makes the cab and control cab more spacious, and easy to operate.
Six unique manufacturing technologies ensure the high quality.
