General Duty Buckets are for digging in low impact, lower abrasion materials, such as dirt loam, and mixed compositions of dirt and fine gravel. A lighter structure decreases load time and increases the weight that can be lifted. General Duty Buckets are typical for mass excavation in site development.

This bucket is the most popular excavator bucket style. Heavy Duty Buckets are intended for a wide range of impact and abrasion conditions, including mixed dirt, clay and rock. They are a good “center line” choice, or starting point, when application conditions are not well known. They are recommended for trenching in utilities work and for the general contractor working in a variety of different situations.

Severe Duty Buckets are for digging in higher abrasion material, such as well shot granite and caliche. Wear areas are larger and tips are up-sized over General Duty and Heavy Duty Buckets.

These buckets are designed for cleaning ditches, sloping, grading and other finish work. Their shallow depth and compact size make working in confined areas easier. Drainage holes allow liquid to empty, so material dumps more easily. Ditch Cleaning Tilt Buckets are also available.

This bucket is designed with a patented recessed pin to provide maximum digging performance while keeping the versatility and convenience of a coupler. Tip radius is reduced and allows up to 10% improvement in breakout force when compared to a conventional pin-on bucket and coupler combination. Center-Lock Pin Grabber Performance Buckets are available in General Purpose and Heavy Duty durability categories.

Power Buckets are for use in abrasive applications where breakout force and cycle times are critical — and for use in materials such as tightly compacted mixed dirt and rock. Breakout force is maximized due to decreased tip radius and increased pin spread. Machine cycle times in most material is improved over a standard bucket in a similar application. Heavy Duty Power Buckets are available in several different widths.

Wide Tip Buckets are intended to perform best in low-impact materials, such as dirt and loam, where leaving a smoother floor and minimal spillage is necessary. The bucket is engineered to be used exclusively with Cat Wide Tips. Corner adapters face straight forward to create a smooth edge. General Purpose Wide Tip Buckets are available in several widths.

Cat Vibratory Plate Compactors provide superior compaction force in a reliable, low-maintenance package. Four different models produce high-power impulses at a rate of 2200 impacts per minute and drive soil particles close together for solid, stable compactions. They are the right attachment for trenching, sloping and driving sheeting or posts.

Quick couplers increase the machine's versatility on the jobsite by allowing the machine to swap between buckets and attachments with standard pins. Center-Lock features a highly visible red lock, making it clear when the coupler is locked on. An operator can be confident the attachment is engaged, which makes swapping tools faster.

Contractor Grapples are strong, durable tools designed for structural demolition, material handling and sorting, loading and unloading rock, scrap, pipe, waste material and other small or large debris. Their 2-over-3 tine configuration gives these grapples a large enough surface for material handling and demolition work, yet deeply penetrate into scrap piles.

Trash Grapples maximize loading capacity. Their 4-over-5 tine construction and wide jaws are ideal for handling municipal solid waste, wood chips, wood debris and other low-density material. They are powered by using the excavator bucket cylinder, so no additional hydraulics are required.

Cat Hammers are the perfect solution for demolition, quarry and road building work. Thirteen models are available, including the most recent E Series models for mid-size excavators. Cat Hammers are designed and built for a long service life in tough working environments. Optional autolube systems and wear packages are available.

Secondary Pulverizers fine-crush concrete and concrete blocks resulting from site demolition. Wide jaws with pick-up tips and numerous teeth, a large opening, reversible cutting edges and rapid closing time helps reduce the largest possible amount of on-site concrete in the shortest possible time.

One of six purpose-built interchangeable jaw sets, Shear (S) jaws are used primarily for structural demolition. With fully reversible blades, the Multi-Processor with S jaw can be used for cutting angle and channel iron, beams, pipes, rebar and cable and piercing steel. A straight lower jaw blade spreads steel out and prevents it from compacting during the cut. The jaw includes a weld-on piercing tip and wear plate in the upper jaw, a cross blade and guide blades in the lower jaw. Together these features cut effectively and provide protection against wear.

Concrete Cutter (CC) jaws combine the steel cutting capability of a shear with the capability of a concrete crushing pulverizer. Crushing teeth reduce concrete and allow the shear blades to cut through rebar. When concrete is heavily reinforced with large diameter rebar, these jaws are ideal for processing it.

Crusher (CR) jaws are used to take down a concrete structure in fairly large sections for further processing with mobile or stationary off-site crushers. Such crushers are capable of processing concrete with rebar, provided the length is limited to around five feet. Rebar cutters in the throat are used for this purpose.

Primary Pulverizer (PP) jaws are significantly wider and feature almost twice the number of crushing teeth when compared to CR jaws. This makes it possible not only to demolish reinforced concrete structures but also, in the process, to  pulverize the concrete and clean it off the rebar. The concrete can then be used on the jobsite as fill material, and the cleaned rebar can be sold at higher-than-ever steel scrap prices.

Secondary Pulverizer (PS) jaws are designed specifically to process reinforced concrete demolition debris by cleaning the concrete off the rebar. In contrast to other concrete crushing jaws, the lower PS jaw has no opening through which the pulverized concrete can escape. This results in finely pulverized concrete and complete rebar and concrete separation — a must if the contractor has an opportunity to sell rebar to scrap recycling yards.

Tank Shear (TS) jaws are designed to cut steel plate — up to 1.2 inches — as used on barges, ships, railway cars and grain, water, oil and fuel tanks. A total of nine blades around the periphery of the upper and lower jaws leaves cut edges flat and smooth, resulting in high density container loading.

Rakes on an excavator are great for grubbing, piling and loading trucks and grinders in general construction and forestry situations.

Cat Shears are essential tools in scrap yards and on demolition sites. They rotate 360 degrees, allowing the operator to place them into the optimal cutting position for the job at hand. Six shear models are available, with the two larger models featuring a bolt-on piercing tip with fully reversible blades.

Hydraulic Thumbs provide excellent load retention for the bucket and are ideal for use on construction, forestry, demolition and land clearing jobs. They work with both pin-on buckets and buckets using either Cat coupler option. No-Link or Full Rotation styles are available.

The bucket curls in to the Stiff Link Thumb to pick, grab, sort and handle all types of material. Cat Stiff Link Thumbs can deploy or store with no tools or assistance. Removal and replacement of one pin and using the curling of the bucket is all that's required. Patent-pending alignment system visually shows the operator when the positioning pin holes are aligned. The thumb can be put in two working positions (90� and 105�). When not in use, it can be folded up and out of the way against the stick with ease.
