1. Strong lifting capacity: The rated lifting weight is 70 tons, which can meet the requirements of many large object lifting operations and handle heavy object lifting tasks in various complex working conditions.
2. Good operating range: The main boom length is relatively long (such as 44.5m for the fully extended boom of the QY70K-I), and with the addition of the jib, the operating space and height can be further expanded.
3. Operating speed:
   • The main winch and auxiliary winch have relatively fast speeds (such as the fully loaded main winch of the QY70K-I at 75m/min, empty load at 130m/min, the fully loaded auxiliary winch at 98m/min, and empty load at 108m/min), which is beneficial for improving work efficiency.
   • The time for fully extending and retracting the boom is relatively reasonable (such as 150s for the fully extended boom of the QY70K-I).
   • The slewing speed is relatively fast (generally reaching 2r/min or more), which can quickly adjust the lifting direction.

1. The boom is made of high-strength steel (such as an octagonal or other special design), which ensures strength while reducing its own weight and providing good stability.
2. Chassis design:
   • A specially designed chassis system that matches well with the upper lifting part to ensure overall driving and operating stability.
   • Reasonable axle load distribution (such as the axle loads of the front axle, middle and rear axles, etc.).
3. The outrigger span is reasonable (such as 6.1×7.3 in the longitudinal and transverse directions), which can provide a good support base for operations and ensure smooth lifting operations.

1. Advanced moment limiter system: It has functions such as color LCD display, intelligent fault diagnosis, and leads the industry in accuracy.
2. Unique telescoping technology prevents core tube bending, cylinder bending, and boom fractures caused by incorrect operations, improving operational safety.
3. Cab and control room design:
   • The humanized design provides a spacious and comfortable operating space for easy operation.
   • The field of vision design may be reasonable, facilitating the operator to observe the operating environment.

Adaptability aspects

1. Configured with high-power air conditioning system: Meeting the requirements of T3 working conditions, high-power air conditioning is equipped in both the cab and the control room. The heat exchange area of the condenser is increased by 75%, the displacement of the compressor is increased by 20%, and the cooling effect is improved by more than 25% compared to conventional products.
2. Super powerful hydraulic heat dissipation system: The oil port layout of the radiator is optimized, the heat dissipation area of the heat dissipation core is increased by 50%, the heat dissipation power of the hydraulic oil radiator is increased from 10kW to 18kW, allowing the ambient temperature to exceed 55 ºC to meet the requirements of high-temperature operations.
3. High-temperature resistant and aging-resistant wiring harness: The wiring harness protective layer is produced in accordance with QC/T 29106 – 2004 “Technical Conditions for Low-Voltage Wiring Harnesses of Automobiles”, the heat resistance temperature is increased to 105 ºC, and bellows protection is added. The protection level of the plug is IP 67, and the service life in high-temperature working conditions exceeds 15 years.
4. High-temperature resistant sealing elements: Key hydraulic components such as hydraulic pumps, hydraulic motors, telescopic cylinders, luffing cylinders, steering assist cylinders, lifting cylinders, and telescopic cylinders have upgraded sealing elements made of high-temperature resistant silicone rubber lip seals, and the working efficiency is increased by 10%.
