Spring-Assisted Locking System

The spring-assisted mechanical system is designed to simplify the process of securing compatible attachments. It eliminates the need for a hydraulic locking circuit while providing a mechanical connection between the excavator and attachment.

Depending on the excavator and attachment geometry, the coupler may also provide approximately 6" (150 mm) additional digging depth. Actual digging depth will vary according to the machine, coupler, attachment, and mounting configuration.

Durable Construction

The coupler features hardened steel locking components and reinforced pivot points designed for repeated attachment changes under suitable operating conditions.

The spring mechanism is designed for use in demanding jobsite environments, but regular inspection and maintenance are recommended. Check the locking mechanism, spring components, pins, pivot points, and attachment connection before operation.

Compatibility

The CAEL Spring-Lock Excavator Coupler is intended for compatible 2–2.5 ton mini excavators with:

• 30 mm mounting pins
• 100 mm pin center-to-center spacing
• 96 mm dipper gap
• Compatible attachment geometry

Important: Excavator weight class and pin diameter alone do not guarantee compatibility. Confirm the complete coupler dimensions, mounting geometry, attachment specifications, and machine configuration before ordering.

Always verify that the attachment is fully secured and locked before operating the excavator. Follow all applicable equipment manufacturer's safety and operating procedures.
