CASE 9020B CRAWLER EXCAVATOR

The Case 9020B is a crawler-mounted hydraulic excavator engineered for versatile earthmoving and material handling applications. This compact yet capable machine features a turbocharged and aftercooled 4TA-390 diesel engine delivering 106 horsepower at 2200 rpm with maximum torque of 325 lb-ft, powered by a 36.5 gpm hydraulic pump system pressurized to 4550 psi. Operating at 35,274 pounds, the 9020B presents an 8.5-foot track width and 1.5-foot ground clearance, facilitating accessibility in confined job sites while maintaining ground pressure of just 5.5 psi to minimize surface disturbance. Two boom-stick configurations are available, with Option 1 achieving a 30.2-foot maximum cutting height and 29.3-foot horizontal reach, while Option 2 extends these to 31.5 feet and 30.6 feet respectively, enabling maximum digging depths of 20.1 and 21.2 feet. The machine accommodates variable bucket capacities ranging from 0.5 to 1.2 cubic yards, optimizing performance across diverse material types. The undercarriage employs 43 shoes per side with seven track rollers and two carrier rollers, generating 28,880 pounds of drawbar pull with a maximum travel speed of 3.4 mph. The 63-gallon fuel capacity and hydrostatic transmission ensure extended operational duration, while the 24-volt electrical system with 45-amp alternator supports auxiliary hydraulics. With its robust hydraulic architecture, precise digging depth control to 17.3 to 19.1 feet on vertical walls, and compact 9.6-foot shipping height, the 9020B remains an industry standard for productive mid-size excavation operations.
