YUTONG YTQU70 Hydraulic Crawler Crane

1. Main Technical Parameters of YTQU70

Performance characteristics of YTQU70

1. Excellent performance of engine: 6CTAA8.3-C215 horsepower Cummins diesel engine, strong power, reliable performance, economic and environmentally friendly.

2. High strength, reliability and stability of chassis. The retractable chassis structure has an extended folding bracket. The length and width of crawler during the working period are respectively 5955 and 4830, while the width of crawler plate during the working period is 800. The ground pressure is small and the stability of complete vehicle is good. The pitch diameter of the slewing bearing reaches 1602 mm with large bearing capacity and strong impact resistance. The built-in planet gear reductor and high torque running motor have a large driving force and strong gradeability.

3. The single rope of the lift winch has large pull force and quick lifting speed: 107 main pump (double-pump) drives 160 motor. Due to large pull force, the working efficiency becomes high. (The multiplying power of main lift with 70t weight is 10, while the multiplying power provided by some manufacturers is 12)

4. Convenient and flexible operation: hydraulic control system adopts pilot handle operation and fine motion function; it is convenient and flexible; the slewing mechanism possesses controlled free skating function; the operation is stable and shock-free. (The operator can sit inside the cab to extend or withdraw the crawler when he is operating the crawler crane manufactured by Yutong Heavy Industries. However, the operator should go to the lower-vehicle platform and manually extend or withdraw the crawler when he is operating the crawler crane manufactured by some other manufactures. In this condition, the security becomes poor.)

5. Capable of long-time large-power working: the independent radiating system equipped on hydraulic system can guarantee the hydraulic system to work for long time and with large power.

6. High safety: It is equipped with safety devices such as swing locking device for rotary table of upper-vehicle, anti-overturn device for boom, and over-rolling protection device for winch. Moreover, it is also equipped with limiting device for the lifting of arm frame and lock mechanism for winch ratchet.

7. User-friendly design: A-shaped frame, lift cylinder, air-conditioning, adjustable seat (which can be adjusted forwards, downwards, leftwards and rightwards) and pilot main switch for cutting off the power source when driver gets off the vehicle, etc. Efficient, convenient and safe electric pump is provided. The maximum counterweight weight is 6 tons, so 8 tons truck crane can be used for assembly. This can reduce installation costs for users.
