Model Number: QY70K-I Brand Name: ORIEMAC Key Specifications/Special Features: Heavy lifting crane truck with 70 tons lifting capacity QY70K-I 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. The torque limiter adopts colorful LCD display, realizing the intelligence of the failure diagnosis. The precision is ahead of the industry. Adopt the new hydraulic motor with big torque starting point, making the secondary lifting safer. The humanity design makes the cab and control cab more spacious, and easy to operate. Six unique manufacturing technologies ensure the high quality. The working condition expands twice. Newly add 5t counterweight.
