DURABLE
Elevated sprocket, rugged structures and proven systems give you long life and durability.
TOP PERFORMANCE
Differential steering and two-pump hydraulics give you the power and precision you need to maximize your productivity.
Caterpillar has body options to meet your material type and application needs. Cat truck bodies will last the life of the truck if properly configured, guarded, and maintained.
Both optional and standard features like those described here can increase the productivity of your operators:
An important differentiator for Cat trucks is their outstanding brake performance. The design principle is one of long-life and excellent performance in quarry, mine, and earthmoving applications.
Cat trucks are known throughout the industry for reliable, long-life frames. Built for off-road maneuvering and haul road conditions, Caterpillar uses castings in high stress areas and box section construction to manage torsion-loading.

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:
