Heavy-duty demolition excavator engineered for high-reach wrecking, structural shearing, and concrete processing in extreme environments.
EXECUTIVE SUMMARY The Demolition Digger represents a paradigm shift in controlled dismantling and structural reduction. Designed for the rigorous demands of high-rise demolition, bridge deconstruction, mining overburden removal, and agricultural silage processing, this machine combines raw hydraulic power with surgical precision. Leveraging a heavy-duty undercarriage and a two-piece high-reach boom, the unit delivers exceptional stability and breakout force while minimizing machine footprint on congested job sites. Built for contractors who demand zero-compromise uptime, the Demolition Digger integrates a Tier 4 Final powerplant with a fully independent hydraulic cooling system. This configuration ensures continuous operation during prolonged shearing, pulverizing, or hammering cycles. The machine’s value proposition centers on lowering total cost of ownership through modular guarding, extended service intervals, and factory-integrated telematics for predictive fleet management.

STRUCTURAL INTEGRITY & POWERTRAIN The chassis is fabricated from DOMEX 700 MC high-yield-strength steel, providing 700 MPa tensile resistance while maintaining a 15% weight reduction versus conventional AR400 designs. Full-length track guiding guards, rock guards, and a belly pan with 25mm HARDOX 450 liners protect against falling debris and ground impacts. The upper structure integrates a cast steel pivot joint with taper roller bearings, rated for 40% higher dynamic loading compared to welded designs. Power is delivered by a Cummins X12 Stage V / EPA Tier 4 Final diesel engine, producing 310 kW (416 HP) at 1,900 rpm. The selective catalytic reduction (SCR) and diesel exhaust fluid (DEF) system enables uninterrupted operation in regulated zones. The closed-loop hydraulic system features three variable-displacement axial piston pumps delivering 2 x 430 L/min at 34.3 MPa (4,975 psi). Efficiency peaks at 88% due to independent metering valves and an electro-hydraulic load sensing network that reduces flow losses by 22% versus open-center systems. KEY FEATURES & OPERATOR COMFORT - High-Reach Variable Angle Boom: The two-piece boom articulates from -20° to +75° with a reinforced pivot pin diameter of 180mm. A hydraulic cylinder cushioning system absorbs end-stroke shocks when deploying extension beams up to 28m vertical reach. - Intelligent Attachment Management System (IAMS): Automatically recognizes factory-calibrated hydraulic shears, multi-processors, or hammers. Adjusts oil flow, pressure ramp rates, and anti-cavitation logic in 0.2 seconds. Preset for 17 demolition attachments including rotating grapples. - ROPS/FOPS Level II Cab: Sealed and pressurized to 0.5 kPa above ambient. Dual-pane laminated glass (ISO 12509) withstands 2.2 kJ impact. Vibration-absorbing mounts reduce whole-body vibration to below 0.6 m/s² RMS. A 360° object detection radar with zone-configurable audible alerts. - Smart Control & Telematics: 10-inch high-brightness touchscreen displays real-time slew torque, hydraulic oil temperature, and filter restriction. Integrated LTE modem transmits machine health data to fleet portal. Enables geo-fencing, anti-theft engine lock, and predictive filter change alerts. - Dual-Circuit Cooling System: Segregates hydraulic oil and engine coolant radiators with independent variable-speed fans. Maintains hydraulic oil below 85°C during continuous high-load shearing. Automatic reversing fan clears debris every 15 minutes without operator intervention. COMPLIANCE & SAFETY STANDARDS The Demolition Digger holds CE marking (2006/42/EC) and complies with ISO 20474 for earth-moving machinery. Engine meets EPA Tier 4 Final and EU Stage V emission limits (non-road transient cycle). Structural design follows ISO 12117-2 for excavator tip-over protection and ISO 10265 for falling object protective structures. The machine integrates ISO 19014-1 functional safety for electrical/electronic systems with performance level PLr = d. Component manufacturing adheres to ISO 9001:2015 and ISO 14001:2015 standards. All hydraulic hoses meet EN 857 2SC and ISO 11237 high-impulse specifications. Emergency engine shutdown, secondary pilot-lock lever, and two remote isolation switches are factory-standard. TECHNICAL SPECIFICATIONS All values correspond to standard configuration with heavy-duty bucket and 6.5m boom arm (not including optional high-reach extension). Weights include full fuel, hydraulic oil, operator (75 kg), and standard counterweight.
