Our spider excavators safely operate on slopes steeper than people can walk—typically exceeding 60 degrees in any direction. The stabilised undercarriage, articulated legs, and low centre of gravity provide exceptional stability on challenging terrain. The machines maintain full operational capability on gradients that would be impossible or dangerous for standard excavators.

Absolutely. With Creek to Peak capabilities, our spider excavators operate in water up to 2 meters deep. This allows direct access to drainage canals, retention basins, stormwater systems, and natural waterways without dewatering or temporary dam construction. The machines also traverse saturated ground and soft soils where standard excavators would sink.

Remote operation keeps operators safe from multiple hazards, including steep terrain, unstable ground, poor air quality in confined spaces, and traffic on roadsides. Operators position themselves for optimal visibility and precision while remaining protected from worksite dangers. This technology also eliminates confined space entry requirements for many projects, significantly reducing risk and regulatory complexity.

The compact design fits through standard gates and under low structures (minimum 3 meters clearance when the boom is retracted). The articulated boom provides an 8.5-meter reach, accessing areas far beyond the machine’s footprint while the unit remains in a safe, stable position. This enables work under bridges, in utility corridors, and around obstacles impossible for standard equipment.

From grass and reeds to substantial woody vegetation, our attachments handle diverse vegetation types. The mulcher processes material up to 150mm in diameter. The grapple saw cuts trees up to 400mm in diameter and handles debris removal. Brush cutters efficiently clear dense undergrowth. This versatility enables comprehensive vegetation management in a single mobilisation.

Yes, TDG Environmental provides complete service, including waste removal via our grab truck fleet and environmentally responsible disposal. Material suitable for recycling is processed at our Mainstream Recycling facilities, achieving up to 98% beneficial reuse. This integrated approach eliminates coordination issues and maximises environmental outcomes.

We maintain a 24/7 emergency response capability across New South Wales. Mobilisation time varies by location and equipment availability, but we prioritise urgent situations affecting public safety and critical infrastructure. Our equipment’s rapid deployment capability and all-terrain access ensure we reach sites regardless of conditions.

Very few. Main limitations include vertical barriers exceeding the machine’s climbing capability, overhead clearances below 3 meters when the boom is retracted, and water depths exceeding 2 meters. If you’re uncertain about site access, we offer free site assessments to evaluate feasibility and recommend optimal approaches.

Low ground pressure prevents soil compaction and vegetation damage beyond the work area. Precise remote control reduces disturbance. Vegetation is mulched for erosion control rather than removed as waste. We follow environmental management plans, obtain all necessary permits, and work with ecologists when required for sensitive sites. Our methods protect water quality, riparian zones, and aquatic ecosystems.

Full service includes equipment and operator, all attachments needed for your specific project, comprehensive safety management, environmental compliance and permitting, waste removal and disposal, site restoration where required, and detailed project documentation through our UtilityTrack system. You receive a complete turnkey solution.

Yes. The spider excavator crosses railway tracks without contact, enabling safe work in rail corridors without track possession requirements. Remote operation keeps operators safe from road traffic while maintaining visibility and precision. These capabilities make spider excavators ideal for infrastructure corridor maintenance.

We provide comprehensive documentation, including before and after photos, waste disposal records with EPA-licensed facility receipts, detailed work reports, and digital records through UtilityTrack. For larger projects, we supply spatial data showing exact work locations, quantities removed, and asset condition observations.

Our quick-hitch system enables attachment changes in minutes without tools. This rapid changeover capability means a single machine can handle multiple tasks—cutting, mulching, excavating, and grading—in one mobilisation, dramatically improving project efficiency.

Our operators handle all routine maintenance. The machines undergo daily pre-start inspections and are maintained on rigorous preventative schedules. For extended projects, we schedule maintenance to minimise disruption. Equipment reliability is a core priority.
