Precise and smooth operation
* The operation action is customized with a professional slow function, the minimum stable speed of rotation is 0.1°/s, and the minimum stable speed of lifting is 2.5m/min, which satisfies the precise lifting operation.
SUV Travelling in the crane
* The low-speed and high-torque transmission system for construction machinery has strong power and the maximum speed is 90km/h; Meet the requirements of the G class, the driving pass is better.
Energy-saving and environmental protection
* Intelligent multi-power mode energy-saving system, the average fuel consumption of the operation is 3.0L/h, and the overall fuel economy is 20%.
