CASE CX75C MSR CRAWLER EXCAVATOR

Technical Description

The CASE CX75C MSR excavator is a mid-sized hydraulic excavator designed for efficient digging and material handling in compact and semi-confined work environments. It features a powerful 55 hp (41 kW) turbocharged four-cylinder engine with a common rail fuel injection system compliant with Tier 4 Final emissions standards, ensuring reduced fuel consumption and lower emissions. The machine has an operating weight of approximately 17,300 lbs (7,850 kg), balancing stability and maneuverability. Its boom and stick configuration provides a maximum digging depth of about 13.5 feet (4.1 meters) and a maximum reach along the ground of 33 feet (10 meters), enabling versatile excavation capabilities. Hydraulics are optimized for productivity, delivering up to 39.1 gallons per minute combined flow with system pressures up to 4,260 psi on boom, arm, and bucket circuits, ensuring strong digging forces (bucket breakout force approximately 12,800 lbf). The excavator's swing system offers speeds up to 10.4 rpm and a swing torque of 12,500 lb·ft, allowing precise maneuvering. Travel speed reaches up to 3.2 mph with an automatic downshift feature and a drawbar pull of 13,400 lb, suitable for various terrains. Operator comfort is prioritized with a spacious cab featuring increased glass area for enhanced visibility, climate control, ergonomic controls, and a full-color LCD monitor. Safety features include a FOPS Level 1 or 2 cab top guard and a rearview camera for 360° site awareness. The undercarriage includes durable 450 mm grouser shoes with a track length on ground of approximately 9.4 ft and a track gauge of 6 ft 2 in. Fuel efficiency is supported by a 500-hour engine oil change interval and advanced engine cooling for reliable performance. This model integrates advanced hydraulic controls with three operating modes—auto, heavy, and speed priority—tailoring power output for task-specific efficiency.
