Technical Specifications

Efficient Attachment Changes

The hydraulic configuration allows operators to engage and release compatible attachments from the excavator, helping streamline operations when different tools are needed throughout the workday.

Suitable applications may include switching between:

• Excavation buckets
• Grading buckets
• Hydraulic breakers
• Rippers
• Other compatible excavator attachments

The mechanical configuration offers a straightforward alternative for operators who prefer a manually operated attachment-locking system.

Durable Construction

The coupler is constructed from high-strength T1 steel with hardened and greasable lugging pins designed for repeated attachment changes and heavy-use excavation environments.

Regular inspection and lubrication of pins, locking components, mounting surfaces, and hydraulic connections are recommended to support reliable operation and service life.

Compatibility

The CAEL Heavy-Duty Hydraulic Pin Grabber Coupler is intended for compatible 5–6 ton excavators using matching mounting configurations.

The supplied compatibility information includes:

• Caterpillar 305–306 configurations with 45 mm pins
• Komatsu 50–60 configurations with 45 mm pins
• Yanmar 50–60 configurations with 45 mm pins

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

If your excavator uses a different mounting arrangement, contact CAEL to confirm fitment and available mounting options.
