CHANGLIN ZG330 crawler excavator adopts Cummins EFI engine that complies III-stage emission regulations, providing strong power, exceptional durability and improved energy efficiency. The advanced negative flow control hydraulic system enables comfortable operation, high work efficiency and outstanding cost effectiveness. There are four power modes to adapt to different jobsite conditions. The fuel injection system with real-time control realizes complete combustion of fuel, thus improving the fuel efficiency. The reliability and stability of the crawler excavators are guaranteed thanks to the use of full three-dimensional modeling and finite element analysis technology.

The engine used in the crawler excavator is a new generation of high-power EFI engines from Cummins, featuring strong power, low fuel consumption and high reliability.

The newly developed hydraulic system coupled with large displacement pump and high flow valve ensures large flow area, minimized pressure loss, reasonable flow distribution, better movement coordination and easy operation.

The hydraulic cylinders are of large diameter and all the key hinge points are optimally arranged to enhance the digging force of the crawler excavator. The automatic supercharging function is available to enable the digging force to be automatically increased as the load increases. The design of large displacement slewing drive and high gear ratio results in a higher starting torque and slewing braking operation.

The crawler excavator is configured with heavy-duty reinforced boom, short stick, large-capacity bucket, widened heavy-duty chassis and optimized box-shaped structure, to adapt to various working environments even in extremely harsh working conditions.

A 5.7-inch glare-free color monitor features high-resolution and high-brightness. The intelligent electronic monitoring system is has functions of maintenance reminding, automatic fault diagnosis and alerting.
