GREASE LUBRICATED UNDERCARRIAGE

Undercarriage rollers are rebuildable and sealed to prevent dirt and debris from causing internal wear. Grease lubricated links minimize internal bushing wear reducing noise and increasing life up to 25%. Two robust undercarriage options providing optimized stability based on bucket selection

DURABLE FRONT STRUCTURES

We designed the heavy-duty stick and boom structures using high tensile steel fabricated into a large box section using internal baffles to absorbtional stress for longer life in quarry applications.

TIME-PROVEN CARBODY

The X-shaped, box-section carbody provides excellent resistance to torsional bending dissipating stress throughout the base of the machine.

  • Heavy Duty Boom and stick.
  • Different choice of undercarrriage to suit your application.
  • Heavy duty frames that stands to the toughest application.

INCREASE EFFICIENCY WITH AN ELECTRO-HYDRAULIC SYSTEM

Maximize uptime and extended service intervals, thanks to advanced hydraulic oil filter design and no pilot and case drain filters. A two-stage fuel filter and anti-rust fuel tank help protect the engine against low-quality fuel.

  • Entire Pilot system replaced by Electro Hydraulic technology.
  • Electro-hydraulic valve provides required flexibility to limit restriction so energy waste.
  • Significant reductions in hydraulic hose length and number of connections reduces potential for leaks
  • Lower fuel consumption while maintaining controllability
  • Customization to operator preference / style
  • Lower maintenance cost
GROUND LEVEL MAINTENANCE

Most service locations are easily accessible at ground level to allow service and maintenance to get completed quickly and efficiently. A service door on the right side of the upper structure allows ground-level access to the hydraulic pumps, hydraulic filters, engine oil filter, and fuel filters.

BUCKETS

Cat buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine to ensure optimal performance and fuel efficiency.

CENTER-LOCK™ PIN GRABBER COUPLER

Center-Lock is a pin grabber coupler and features a patent-pending locking system. A highly visible secondary lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool..

H120GC

Cat® Hammers make short work of your demolition, construction, and quarry needs. Combine the simple, lightweight design of the GC Hammer series with the reliability, durability, and value you expect from Cat products. The result is a low cost per hour solution providing the consistent power and performance you need.

RIPPERS

Constructed from high-strength steels and built to last, Cat rippers endure in the toughest conditions. The box-section structure is reinforced for maximum rigidity, transmitting the full machine power to the material being ripped. Rippers feature a replaceable wear tip, and most models also come equipped with a replaceable shank protector.

GRAPPLES

Cat grapples make Cat excavators the ideal machine for handling loose material, sorting trash, and demolition site cleanup. An array of styles and sizes is available to match excavators to the task at hand.

MULTI-PROCESSORS

Multi-processors do the work of many types of demolition tools by use of interchangeable jaw sets. Changing jaws allows a single unit to crush, pulverize, and perform a variety of specialized tasks such as cutting steel rebar and tanks.

SHEARS

Cat shears are designed to take full advantage of the hydraulic flows and pressures produced by Cat excavators – all to enhance productivity without compromising safety or causing premature wear of the shear or carrier.

PULVERIZERS

Mechanical pulverizers are cost-effective tools for recycling demolished concrete debris. The bucket cylinder on the excavator powers the pulverizer, eliminating the need for a dedicated cylinder, associated hydraulics, and additional installation cost.

VIBRATORY PLATE COMPACTOR

Cat compactors make job site compaction quick, efficient, and cost effective.

CRUSHER

The hydraulic concrete crusher is well suited for demolition in residential areas. The tool combines several demolition operations in one piece of equipment:
