Case 9010B Hydraulic Excavator Overview and Specifications

[MikePhua]

Machine Introduction
The Case 9010B is a medium-sized hydraulic excavator designed for durability, versatility, and efficient operation in construction and earthmoving applications. With a robust design and powerful hydraulic system, it is suited for tasks requiring reliable digging, lifting, and material handling.
Engine and Power

• Equipped with a Case 4TA-390 four-cylinder, 4-stroke turbocharged and aftercooled diesel engine.
  
• Engine displacement is 239 cubic inches (3.9 liters).
  
• Rated power output approximately 106 hp (79 kW) at 2200 rpm.
  
• Maximum torque about 290 lb-ft (393 Nm) at 1600 rpm.
  
• Fuel capacity is around 63.4 US gallons (240 liters).
  

Hydraulic System

• Dual variable displacement axial-piston pumps provide hydraulic flow capacity ranging from 20 to 32 gallons per minute (76 to 121 L/min).
  
• The system operates at a standard relief pressure of approximately 4550 psi (31,400 kPa) and a power boost up to 4975 psi (34,300 kPa).
  
• The hydraulic circuit includes multiple control valves: a 4-spool section controlling right track travel, auxiliary functions, swing, and arm, plus a 3-spool section for left track travel, boom, and bucket.
  
• Boom holding valves improve safety by preventing uncontrolled boom descent.
  
• The hydraulic system supports a single or dual-pump double-acting auxiliary function for attachments like thumb kits.
  

Dimensions and Performance

• The boom extends 15 feet 5 inches (4.7 meters) with arm options of 8 feet 2 inches (2.5 m) or 9 feet 10 inches (3.0 m).
  
• Operating weight approximately 28,000 pounds (12,700 kg) with standard equipment, full fuel, operator, and an 8’2” arm with 902 lb bucket.
  
• Track system includes 44 triple grouser shoes per side, six bottom rollers, and two top rollers.
  
• Travel speeds vary from 1.4 mph (low) to 3.4 mph (high) with a three-speed axial piston motor driving each track.
  
• Drawbar pull rating is 22,260 lbs (99 kN).
  
• Hydraulic cylinders feature robust bore and rod sizes tailored for boom, arm, and bucket tasks, providing high breakout and lift forces.
  

Operator and Electrical Systems

• Equipped with a 24-volt electrical system powered by a 45-amp alternator and low-maintenance batteries.
  
• Operator comfort includes ergonomic layout and controls for responsive operation.
  
• Instrumentation displays vital hydraulic and engine information to monitor system status.
  

Attachments and Accessories

• Compatible with a 5’ to 10’ radius reach for buckets and hydraulic attachments.
  
• Option for hydraulic or mechanical couplers such as Case’s Slide-Loc™ and compatibility with JRB® attachments.
  
• Optional heavy-duty bucket linkages for demanding digging or materials handling requirements.
  

Terminology

• Variable Displacement Pump: Pump adjusting fluid flow with hydraulic demand.
  
• Double-Acting Cylinder: Hydraulic actuator providing power in both extension and retraction.
  
• Triple Grouser Shoes: Track shoes with three protrusions for improved traction on rough terrain.
  
• Power Boost: Temporary increase in hydraulic pressure for heavy-demand situations.
  
• Drawbar Pull: The pulling force the machine can exert moving forward.
  

Real-World Applications
The Case 9010B excels in urban construction, trenching, utility installation, and medium-scale earthmoving jobs. Its balance of power, maneuverability, and hydraulic precision makes it a favorite for operators requiring consistent performance with versatile attachment use.
Conclusion
The Case 9010B hydraulic excavator combines a powerful turbocharged engine, advanced hydraulic system, and durable undercarriage to deliver reliable performance in construction and excavation applications. Understanding its specifications assists operators and technicians in maximizing efficiency, performing preventive maintenance, and optimizing attachment productivity across job sites.
