Technical Specifications

Efficient Attachment Changes

The hydraulic configuration is designed to allow operators to change compatible attachments from the excavator, helping reduce the time associated with manual attachment changes.

It can be used with compatible:

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

For applications where hydraulic attachment locking is not required, the mechanical configuration provides a manually operated alternative.

Heavy-Duty Construction

The coupler is fabricated from high-strength T1 steel, with hardened and greasable lugging pins designed for repeated attachment changes and demanding working conditions.

Routine inspection and lubrication of the pins, locking mechanism, mounting surfaces, and hydraulic components are recommended to support dependable operation.

Compatibility

The CAEL Heavy-Duty Hydraulic Pin Grabber Coupler is intended for compatible 7–10 ton excavators using matching mounting configurations.

The supplied compatibility information includes:

• Caterpillar 307–308 configurations with 50 mm pins
• Yanmar 70–100 configurations with 50 mm pins

Important: Excavator weight class and pin diameter alone do not guarantee compatibility. 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.
