The Case CX36 compact hydraulic excavator weighs approximately 8,046 lbs (3,650 kg) and is designed for versatile operation in confined construction and landscaping sites. It features a robust hydraulic system optimized for responsive performance.
- The machine uses two variable displacement axial piston pumps, each delivering about 9.2 gallons per minute (34.8 liters/min), combined with a fixed displacement gear pump supplying about 6.7 gallons per minute (25.2 liters/min) for auxiliary functions.
- The hydraulic system’s standard relief pressure is rated at approximately 3,270 psi (29.4 MPa), providing high system efficiency while ensuring component protection.
- Pilot controls drive the left and right track travel, boom, arm, bucket, and swing functions through a 10-spool control valve assembly, delivering precise operator control.
- Auxiliary hydraulics support attachments including breakers and backfill blades.
- The swing motor is a fixed displacement axial piston design offering up to 8.6 revolutions per minute, with spring-applied, hydraulically released brakes featuring dual cushion relief to manage and smooth boom swing.
- Travel motors use two-speed axial piston designs paired with planetary final drives, enabling travel speeds of about 1.6 mph in low and 2.8 mph in high gear and supporting a gradeability of 30° (58%).
- Boom cylinders measure roughly 3.35 inches (bore) by 1.97 inches (rod) with a 20.91-inch stroke (canopy model), or 3.15 inches by 1.77 inches with a 20.39-inch stroke (cab model).
- Arm cylinders have a 3.15-inch bore, 1.77-inch rod diameter, and 22.05-inch stroke, providing solid digging force.
- Bucket cylinders with 2.56-inch bore and 1.38-inch rod offer 19.18-inch stroke, achieving bucket digging forces around 5,745 lbs (2,606 kg).
- Boom swing allows 70° left and 60° right rotation, with zero tail swing radius enhancing maneuverability in tight spaces.
- The hydrostatic drive and well matched hydraulic system provide smooth control and strong dig forces.
- Hydraulic oil tank capacity is about 9.8 gallons (37 liters), with total system capacity 12.7 gallons (48 liters), facilitating consistent fluid supply and cooling.
- Engine is a Yanmar 3TNE82A-YBD 3-cylinder diesel, Tier 4 Final certified, producing about 23.1 hp (17.2 kW) at 2400 rpm.
- Fuel tank holds approximately 10 gallons (38 liters), and the machine runs on 12-volt electrical system powered by a 40-amp alternator.
- Operator cabin options include ROPS/FOPS certified four-post canopy or enclosed cab with heater and climate controls.
- Piloted hand controls and foot pedals offer intuitive operation.
- Multiple caution lamps and gauges monitor engine oil pressure, water temperature, battery charge, fuel level, and glow plug status.
- Improved visibility, compact tail swing, and compact overall dimensions add to job site efficiency and safety.
- Axial Piston Pump: A variable displacement pump delivering hydraulic fluid in accordance with demand.
- Pilot Controls: Low pressure hydraulic input device controlling fluid flow and direction.
- Hydraulic Relief Valve: Ensures system pressure does not exceed safe limits.
- Travel Motor: Hydraulic motors powering track movement.
- ROPS/FOPS: Roll-Over Protective Structure and Falling Object Protective Structure ensuring operator safety.
