The CAEL Compact Hydraulic Pin Grabber Coupler is designed for 1.8–2.5 ton excavators, providing a convenient way to switch between compatible attachments. Its compact design and hydraulic locking system can help reduce manual attachment changes when operators frequently switch between buckets, augers, breakers, and other tools.

Constructed from T1 steel with hardened, greasable lugging pins, the coupler is designed for demanding compact-excavator applications. A mechanical locking configuration is also available for operators who prefer a simpler attachment-change system.

Technical Specifications

Fast Attachment Changes

The hydraulic configuration allows operators to change compatible attachments from the excavator, reducing the need for repeated manual pin removal.

The coupler is suitable for applications where operators may regularly switch between:

• Excavation buckets
• Grading and cleanup buckets
• Augers
• Hydraulic breakers
• Other compatible mini excavator attachments

For operators who prefer a mechanically operated system, the available mechanical configuration provides a straightforward alternative without hydraulic components.

Durable Construction

The coupler is fabricated from high-strength T1 steel and uses hardened, serviceable lugging pins designed to withstand repeated attachment changes and working loads.

Greasing and routine inspection of pins, locking components, mounting surfaces, and hydraulic connections are recommended to support reliable operation.

Compatibility

The CAEL Compact Hydraulic Pin Grabber Coupler is intended for compatible 1.8–2.5 ton excavators with matching mounting geometry.

The supplied compatibility information includes:

• Caterpillar 301–302 pin configurations
• Machpro MP46 pin configurations
• Bobcat E20 pin configurations
• STE35SR configurations

Important: Excavator model or pin configuration alone does not guarantee fitment. Before ordering, confirm the machine's pin diameter, pin center-to-center spacing, dipper gap, lug dimensions, mounting geometry, and hydraulic requirements.

If your machine uses a different mounting configuration, contact CAEL to confirm compatibility and available mounting options.
