Overview
Cat® buckets are more than just an add-on, they are an extension of your Cat machines. Each one is perfectly balanced to our excavators so you can take on heaping loads without compromising fuel efficiency or machine health. We built them to fill faster, retain your load, and fit your task. Not all attachments are available in all regions. Consult your Cat dealer for specific attachments available in your region.
Features At A Glance
- Productivity is at its best when you pair your Cat machine with a Cat bucket, which we purpose-design to optimize the breakout force and power of the machine.
- The dual radius shell profile improves material flow into the bucket. The added heel clearance ensures the bottom of the bucket does not drag, reducing maintenance costs.
- Fuel consumption peaks during digging. Cat buckets are designed to cut through material quickly to enhance your machine's overall operating efficiency.
- Load more material in less time. Bucket shape and sidebars keep the most material in your bucket for every load.
- Count on the structural integrity of your bucket long-term. The integrated hinge plate helps distribute force better than a weld-on hinge plate
- Cat buckets are manufactured with high-strength, abrasion-resistant steel, especially in excessive wear areas
- Protect the high wear areas of your bucket coming into contact with materials the most with Cat Ground Engaging Tools (GET)
- Get higher production in demanding applications, easier penetration into piles, and faster cycle times with Cat® Advansys™ GET
- Install and remove tips faster than ever with the Advansys hammerless GET system
- Ensure a secure fit for tips and adapters, using only basic hand tools, with CapSure retention
- Reduce maintenance costs by selecting the right GET for your bucket and application combination. Bucket tips are available in a variety of options to suit your specific application needs.
- Managing multiple buckets and other attachments for a fleet is easier with a coupler system. Couplers allow machines of similar sizes to share and attachments can be changed out in seconds without leaving the safety of the cab.
- Buckets capable of being pinned directly to the machine are also compatible with Cat® Pin Grabber Couplers, except Pin Grabber Performance buckets. Pin Grabber Performance buckets have a recessed pin which optimizes breakout force resulting in faster cycle times for your bucket when using with a Cat Pin Grabber Coupler.
- The Cat Pin Grabber Coupler also gives the operator the ability to pick up a bucket in reverse position to clean out and square corners with ease.
- Ensure your attachments are secure with audible and visible cues from the coupler's secondary latch, always in the operator's line of sight.
- Cat Pin Grabber Couplers are compatible with 311-352 tracked excavators and all wheeled excavators. Trenching width couplers are also available.
- Attachments compatible with the CW Dedicated Coupler system use fixed quick coupler hinges. CW Dedicated Couplers feature a wedge-style locking system to keep attachments secure.
- CW Dedicated Couplers are available for all tracked and wheeled excavators.
- Never waste time looking for your buckets again. Cat asset tracking is available on select buckets.
- Track your entire fleet of attachments and machines from one source. Buckets with asset tracking can be viewed within VisionLink® alongside Product Link ™ subscribed equipment.
- Keep your assets secure. Buckets with an asset tracker send an alert if they leave an easy-to-setup site boundary.
- For situations where your application conditions may change, Heavy Duty buckets are the most practical choice for your operation, with widths ranging from 450-2150 mm (18-85 in.). Their versatility across application types makes them the most popular excavator bucket choice where tip life ranges from 400 to 800 hours.
- Heavy Duty buckets work best in a wide range of impact and abrasion conditions including mixed dirt, clay, and rock.
- Wear plates across the bottom of Heavy Duty buckets range up to 20-40 percent thicker than on General Duty buckets.
- Side wear plates are up to 17-25 percent thicker than their General Duty counterparts
- Heavy Duty buckets for medium to large excavators can expect up to 14-17 percent increase in Side Bar thickness.
- Balance power and efficiency with Heavy Duty Power buckets, Power buckets are best in applications where breakout force and cycle times are critical.
- Dig deeper into rock-type materials with a spade edge. The spade edge helps dig further into these bulky materials and guide them into the bucket.
- You can pin Heavy Duty buckets directly to the machine or use them with a Cat Pin Grabber Coupler or CW Dedicated Coupler.
