1. Excellent performance engine: 6LTAA8.9-C295 horsepower Cummins diesel engine, strong power and reliable performance. The engine adopts two control modes including hand throttle and foot throttle, which can save energy and provide high efficiency.

3. Easy and convenient operation: hydraulic system of YTQU125 Hydraulic Crawler Crane is equipped with pilot proportional control valve; all operating handles and fool valves have automatic reset function; support leg cylinder and pin cylinder are controlled manually, increasing the security during installation.

4. High safety: YTQU125 Hydraulic Crawler Crane is equipped with safety devices such as swing locking device for rotary table of upper-vehicle, anti-overturn device for boom, limiting device for the lifting of arm frame, over-rolling protection device for winch and lock mechanism for winch ratchet. (The main hoist and auxiliary hoist, as well as luffing device, adopt build-in reductor which is equipped with wet-type and maintenance-free brake)

5. User-friendly design of YTQU125 Hydraulic Crawler Crane: 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.
