Features of the QY50K-II Truck Crane
1. The truck crane uses ergonomically designed cab and control cab which are spacious and easy to operate.
2. The precise torque limiter adopts color LCD display to facilitate failure diagnosis.
3. The innovative jib system adopts embedded block, plug-in boom head and U section jib for safe and reliable lifting work.
4. The use of specialized stretch and retraction technique avoids the bending of the core pipe and cylinder and the break of the boom caused by misoperation, improving operation safety.
5. Eight patent techniques are applied to ensure the smooth operation, high efficiency and energy conservation of the lifting, rotation, and luffing systems.
6. The truck crane uses new hydraulic motor with big torque starting point, making the secondary lifting safer.
