The DX300LC-7M is a mid-range crawler excavator designed for construction sites, quarries, and plant hire operations across South Africa. At 31.8 tonnes operating weight with a 192 kW Develon DL08 engine, it handles continuous digging and loading cycles without excessive fuel burn. The 0.8–1.75 m³ bucket range lets you match capacity to material type and site conditions. Whether excavating foundations, loading trucks, or moving stockpiles, this machine balances productivity with operational economy—critical where every litre of fuel and downtime hour counts.Â
The EPOSâ„¢ (Electronic Power Optimising System) continuously matches engine power and hydraulic performance to the demands of the task, ensuring that only the power required is delivered. The optional Electric Transfer Pump (ETP) adjusts front attachment movement according to hydraulic flow demand, providing smoother, more precise control during attachment operation. The result is improved fuel efficiency, lower operating costs and responsive machine performance across a wide range of applications.Â
The VBO (Virtual Bleed Off) system uses electronic control to optimise hydraulic flow, reducing the need for the hydraulic pumps to continuously generate flow when there is no demand. This improves hydraulic efficiency while maintaining the fast, responsive joystick control operators expect. By reducing unnecessary hydraulic flow generation and internal abrasion, VBO contributes to improved fuel efficiency and reliable long-term performance.Â
Structural durability is engineered through X-chassis undercarriage with high-strength track frame, fortified boom and arm pins calculated for load distribution, and sealed track components with floating seals that resist debris ingestion. Advanced pin and disc design minimises wear in dusty quarries and rocky sites where standard machines struggle.Â
Operator comfort and maintenance accessibility: The spacious ROPS-certified cabin provides low noise and vibration levels, excellent all-round visibility and a comfortable working environment for long shifts. Routine maintenance is simplified with grouped boom and arm grease inlets for easy access, a conveniently located fuse box, and service-friendly maintenance features that help maximise uptime.Â
Fuel efficiency protects your margin on contract work. Extended service intervals mean fewer unscheduled maintenance stops. The global Develon parts network ensures genuine components arrive without long delays. Optional telematics monitoring tracks fuel consumption and maintenance schedules in real time, helping you forecast costs and plan preventive work before failure impacts your job.
