Uncompromising Power. Superior Control. Built for New Zealand’s Heaviest Earthmoving.

The DEVELON DX400LC-7M is a high performance 40 tonne crawler excavator engineered to deliver exceptional digging force, advanced hydraulic efficiency, and outstanding durability. Built for large civil construction, quarrying, mining, and high-production earthworks across New Zealand, the DX400LC-7M combines raw power with refined control to maximise productivity in the toughest environments.

Power & Performance.

Powered by the robust Scania DC09 engine, the DX400LC 7M delivers 268 HP with strong torque output for fast response under heavy load. The engine works in harmony with the DEVELON EPOS electronic power optimisation system, ensuring precise communication between hydraulic demands and available power. This results in smoother multi function operation, reduced fuel consumption, and consistently high performance during demanding excavation and loading tasks. The Smart Power Control system further enhances efficiency by automatically adjusting engine speed and pump output based on real time workload.

Hydraulic System.

The machine’s hydraulic system features twin 350-bar main pumps, providing the oil flow required for powerful boom, arm, and bucket forces. Combined with a high efficiency swing drive, operators benefit from fast cycle times, improved controllability, and stable performance during heavy digging and high load movements.

Durability.

Durability is a defining characteristic of the DX400LC-7M. The structure incorporates reinforced boom and arm castings, heavy duty undercarriage components, improved ground clearance, and resilient end disk protection for extended wear life. Engineered to resist external impact and structural stress, the machine is built to withstand the harshest working conditions in New Zealand’s quarry and civil sectors.

The Cabin.

Operator comfort is enhanced through a spacious, low noise cabin featuring an adjustable air-suspension seat, refined control layout, and clear visibility from large glass surfaces. The ergonomically designed interior includes intuitive switch placement, excellent climate control, and smooth joystick response. These features ensure operators can work long hours with reduced fatigue and greater precision.

Maintenance.

Maintenance is streamlined with well positioned service panels, centralised lubrication points, clearly organised fuse and relay panels, an easily accessible cooling system, and ground level access to key components. The design supports quicker daily checks and shorter maintenance cycles, enabling maximum uptime and reduced operating costs.

With powerful performance, refined hydraulics, advanced efficiency systems, and rugged structural strength, the DEVELON DX400LC-7M is built to dominate large scale earthmoving work across New Zealand. Supported by AB Equipment’s nationwide parts, service, and technical network, it is a reliable and productive solution for contractors looking to maximise long term output.
