The Volvo ECR305C Hydraulic Excavator is a robust, mid-sized crawler excavator designed for efficient digging and lifting in confined spaces. It features a Volvo D7EEAE3 six-cylinder, inline, 4-stroke diesel engine with 7.15 liters displacement, delivering a net power output of 92 hp (69 kW) and maximum torque of 1,350 Nm at 1,350 rpm. The engine complies with Tier 3 emission standards, ensuring a balance of power and fuel efficiency, supported by Volvo Advanced Combustion Technology (V-ACT) and common-rail direct fuel injection. The machine operates at a weight of approximately 77,940 lbs (35,320 kg), providing excellent stability through a heavy counterweight and optimized center of gravity.
The ECR305C boasts a short swing radius and class-leading stability, making it ideal for urban construction and tight job sites. Its hydraulic system includes dual variable displacement axial piston pumps delivering up to 526 l/min total flow, enabling simultaneous, smooth boom, arm, and swing operations with hydraulic flow and pressure adjustable from the operator’s cab to maximize performance with various attachments. The swing system offers a maximum speed of 10.8 rpm with 117.6 kNm torque, while the tracked undercarriage features two-speed travel motors, achieving speeds up to 4.5 km/h and a gradeability of 35 degrees.
In terms of excavation performance, the machine provides a maximum digging depth of 22.8 ft and a maximum reach along the ground of 36.0 ft, suitable for a wide range of earthmoving tasks. The excavator’s design includes wide service access for maintenance, a comfortable Volvo Care Cab for the operator, and safety-enhancing 3-point access with handrails. Overall dimensions approximate 32 ft 6 in length, 11 ft 6 in width, and 11 ft 4 in height, supporting versatile job site mobility and transportability.
