Product Description
Power System
1. The modular design is adopted to achieve easy assembling and disassembling and simple repairs.
2. The Weichai WP12 engine conforms to the China-II non-road machinery emission regulation, featuring strong power, low fuel consumption, high intelligence and efficiency, high parts universality, and low maintenance cost.
3. The modular units adopt cushioned installation to isolate the vibration and transmission and promote the machine reliability and life.
4. The normally-closed brake system is adopted to apply the braking whenever the engine is stopped, featuring high safety.
5. The four-point semi-suspension shock-absorbing installation reduces the machine vibration and improves the driving comfort.
Drive system
1. The normally-closed brake design is applied so that the machine is braked automatically after the stop of engine to ensure high safety.
2. The shock absorbers in crossing shaft rubber block structure are applied to effectively mitigate the vibration from the engine and protect the engine and drive system.
Driving/Riding Environment
