沃尔沃 ECR 28

The "ECR" designation indicates that the tail swing of the machine remains incredibly tight to the undercarriage tracks, allowing operators to rotate the upper structure safely next to walls, fences, or active traffic lanes without risking a rear-end collision. Performance & Engine Specifications • Engine: 15.6 kW (21 hp) Volvo D1.1 water-cooled, 3-cylinder diesel engine. • Operating Weight: 2,685 kg to 2,840 kg (approx. 5,920–6,260 lbs) depending on whether it is configured with a canopy or a fully enclosed heated cab. • Maximum Dig Depth: 2,730 mm to 2,980 mm (9' 0" to 9' 9") depending on the choice of standard or long arm/dipper stick. • Bucket Breakout Force: 24.3 kN (approx. 5,463 lbf) providing excellent tearing power through tough roots, clay, and compacted aggregate. Key Design & Operator Features • Short-Swing Versatility: The counterweight overhang is practically zero over the tracks when rotating. This enables operation inside narrow alleys or right up against structural walls where standard conventional excavators cannot fit. • Proportional Auxiliary Hydraulics: Features fingertip-controlled hydraulic roller switches on the joysticks. This setup delivers ultra-precise oil flow control to heavy attachments like hydraulic breakers, augers, or tilting hitches. • Premium Cab Ergonomics: Despite the machine's compact outer dimensions, the Volvo cab layout is widely praised for being exceptionally spacious. It features a wide door for easy entry, intuitive controls, excellent 360-degree visibility, and suspension seating. • Advanced Safety & Durability: Built with heavy-duty cast steel counterweights to wrap and protect the engine compartment from impact damage. It includes Volvo's ROPS, TOPS, and FOPS safety certification to guarantee operator protection in rollover situations.
