Caterpillar Next-Generation Mini Hydraulic Excavators

Caterpillar designed its four Next Generation mini hydraulic excavators—the 301.5 1.5-ton-class, standard tail-swing excavator with a canopy; the 301.7 CR 1.7-ton class, compact-radius excavator with a canopy; the 301.8 1.8-ton-class, standard tail-swing excavator with either a canopy or cab configuration; or the 302 CR 2-ton-class, compact radius excavator with a canopy or cab configuration—to provide performance, versatility, safety and convenience in the smallest possible packages. Features include:

• Approximate minimum operating weights from 3,500 to 4,500 pounds, with weights increasing from 3,900 to 4,900 pounds, depending on the specific machine configuration.
• Dig depths of 7 feet, 8 inches or 7 feet, 9 inches, depending on the model, plus an available long stick to increase depths to 8 feet, 4 inches or 8 feet, 5 inches.
• The hydraulic capacity to generate high digging and lifting forces, as well as to handle powered attachments.
• The Cat C1.1 engine, a three-cylinder diesel rated at 19.2 net horsepower and 21.6 gross horsepower, while meeting Tier 4 Final emissions regulations.
• A fuel-saving, load-sensing hydraulic system with an electronically controlled variable displacement piston pump capable of oil flows to 17.4 GPM.
• A standard auxiliary hydraulic system (complete with quick-disconnect lines) for one-way, two-way and continuous-flow operation.
• An expandable undercarriage that narrows to enter work sites through restricted access points, then extends to provide a stable work platform.
• A dozer blade to handle backfilling and grading tasks, above and below grade, with a float function and dig-to-blade operation for more efficiently handling loose materials.
• The Stick Steer system, which allows the operator to switch with the touch of a button from conventional lever/foot-pedal steering controls to left-hand joystick control for less effort and more operator control.
• Easy-to-read machine information on the LCD monitor and a jog dial for easy, ergonomic interaction with the monitor.
• Protective structures designed to promote a safe working environment for operators. Pressurized and sealed cab models for 1-2 ton models.
• Controls protected via a hydraulic lockout.
• Halogen boom lights to help illuminate the work area.
• A tilt-up cab to allow access to major hydraulic components.
