The main components of ytqu70 hydraulic crawler cr

The main technical parameters of ytqu70 hydraulic crawler crane of Yutong heavy industry are

ytqu70 hydraulic crawler crane is a full swing, multi section truss arm combination, fully hydraulic driven lifting machinery independently developed by Yutong heavy industry to meet the market demand. This model has high performance, high reliability and beautiful appearance, reaching the advanced level of domestic similar products. It is widely used in metallurgy, energy, steel, chemical and other departments for lifting, installation and material transfer operations

this product has the following characteristics:

1. The engine adopts the American Cummins electronic control diesel engine that meets the Euro 3 emission standard, providing a reliable, economic and environmental protection power source

2. The retractable chassis mechanism has an extendable folding support, which not only improves the stability of the chassis, but also does not affect the overall transportation. The crawler telescopic cab can be directly controlled, and the telescopic walking can be carried out at the same time

3. The main hydraulic components are from Kawasaki, Japan, and the operation is controlled by handle pilot

4. The semi enclosed hood design is adopted, which is beautiful and easy to maintain

5. The reducer and drum of the main and auxiliary lifting and luffing devices are installed in a built-in structure

6. The main and auxiliary winch devices that are easy to disassemble sometimes slow down or stop cracking. The auxiliary winch can be interchanged, and the maximum single rope tension of the main and auxiliary winch is 14 tons

7. The main and auxiliary hoisting and luffing winch mechanisms with ratchet locking ensure the safe and reliable positioning of the boom and goods

8. The boom is welded with high-strength structural pipes. The boom head adopts nylon pulley, which has good rigidity, light weight and strong bearing capacity

9. The hydraulic control system with pilot operated load sensing has good fretting performance and high accuracy

10. The rotary mechanism with controllable free sliding function can be operated smoothly without impulse. It is necessary to increase investment and support

11. A torque limiter with reliable performance is installed to monitor the operation status in real time. It is also equipped with turntable rotation locking device, jib anti overturning device, winch anti overwinding, anti overwinding and other safety devices to ensure the safe and reliable operation of the crane

12. Equipped with electronic combination instrument, anemometer, level meter and winch monitoring device, it can display and monitor the working state in real time to ensure the smooth progress of the work

13. The streamlined large arc cab with shock absorption connection is considered to be because graphene can conduct electricity very effectively, with wide electric field and beautiful shape. It is equipped with high-grade shock-absorbing seats, air conditioning system and vehicle DVD system, which greatly improves the comfort of operation. Engine data integrated control, fully electronic control operation, more convenient operation

14. The suspended counterweight is more convenient for installation and disassembly, and convenient for transportation
