Hydraulic Crawler Crane BHQU55
Maximum hoisting capacity capacity 55 t
| Features:1. The Cummins diesel engine with excellent performance makes available reliable, economical and environment-friendly power source so as to make the crane applicable to various working conditions. 2. The chassis with large outer contour enjoys a small ground pressure to ensure the reliability of complete machine and make the crane applicable to the bad ground. 3. The imported speed reducer, motor, pump, valve and hydraulic element enjoy excellent performance and high reliability. 4. The application of the track shoe made of high-strength material ensures strong bearing capacity, and the internal-mounted planetary speed reducer and large-torque motor with mature technology provide large driving force and high reliability. 5. The lifting mechanism, auxiliary lifting mechanism and luffing winch mechanism with ratchet wheel locking function ensure safe and reliable positioning of jib and goods. 6. The truss-type crane jib is formed by welding the high-strength pipes and the jib head is fitted with nylon pulley to ensure favorable rigidity, light weight and strong bearing capacity. 7. The hydraulic system with pilot control load sensor is provided with micromotion function to ensure high precision and easy operation. 8. The rotary mechanism with controllable mid-position floating function ensures stable operation Main Technical Parameter | ||||
