1. It adopts the dedicated hydraulic retractable crawler chassis and large diameter slewing bearing to provide extraordinary
stability and transport convenience. 2. It adopts the electric control turbo-supercharged engine to provide strong power
and conformity with Euro III emission standard.
3. With the hydraulic pressure system adopted threshold power control and negative flow control, the system acquired high
efficiency and higher energy conservation.
