High efficiency and low consumption
Customized power control system
With dual-pump and dual-circuit constant power control system, the engine outputs strong operating force. Optimized performance of the engine reduces power loss. The engine is designed to work in four modes according to different working conditions.
Optimized main valve
The main valve with movement coordination improves boom and arm operating speed, boom-down regeneration, and bucket confluence performance. This enables higher operating efficiency.
The plates welded on the two main beam of swing platform considerably improve the bending resistance performance. Track rollers, carrier rollers and idlers use seal in lubrication that enhances service life. The tri-grouser track shoe rolled with high-strengthened alloy ensures favorable contact, stability and durability.
Optimized boom, arm and bucket
With optimized design, the boom and arm provide considerable working range and depth on the occasion of ditching, excavating and common construction while maintaining powerful digging force. Standard bucket equipped with highly rigid steel sheet, tips and side cutters can serve a longer period.
Safety and Comfort
Adjustable and safe cab
The height of seat, the inclination of backrest, the height of armrest, the seat position and the headrest can all be adjusted as desired. And the sealing ring protects the inner cab from dust and rain. Equipped with thickened steel sheet, the cab roof is strong enough to handle any impact, which greatly improves safety.
The silicone rubber shock absorber is fixed to the swing platform in six points, which minimizes shock from rough road conditions and unexpected impact. This considerably increases the cab stability and operator comfort.
Longer control levers
Base on humanized design, the control levers and joysticks are easy to be reached from any position.
