2. The retractable chassis structure has an extended folding bracket to improve the stability of chassis and at the same time not to influence overall transportation.
3. The hydraulic crawler crane is featured with large driving force, strong gradeability and high reliability by adopting built-in planet gear reducer and high torque running motor.
4. By adopting dual brakes, the main winch, with the function of high speed free lowering, not only greatly improve working efficiency but also guarantee brake reliability.
5. The derricking winch mechanism equipped with ratchet locking device (Main winch can also be equipped in accordance with customer's requirements) guarantee the safe and reliable positioning of boom and goods to avoid accidents.
6. The boom is formed by welding high strength structural pipe; the boom head adopts nylon pulley which is featured with good stiffness, light weight, and high carrying capacity.
7. The hydraulic crawler crane is designed with pilot controlled, load sensing hydraulic control system, with the advantages of high micro-motion performance, high accuracy, convenient and flexible.
8. The crawler crane adopts swing mechanism with a controllable free slipping mechanism to realize stable operation.
9. The vehicle is equipped with a reliable and high performance torque limiter to monitor the working condition in real time. It is also equipped with safety devices such as rotary table swing locking device and boom anti-overturn device to ensure safe and reliable operation.
10. The crawler crane is able to monitor and real-time display working state by adopting combination instrument to realize integrated control of engine data. Anemometer, level gauge and electric megaphone are optional devices for safe and smooth work.
11. The crawler crane is designed with streamline shape grate circle cab with broad vision and artistic outline. The top grade shock absorbing seat, fan, heater and MP3 audio player make it comfortable while operating the vehicle.
