Technical Specifications

Applications

The CAEL Spring-Lock Attachment Coupler is suitable for:

• Landscaping
• Utility work
• General excavation
• Property maintenance
• Rental equipment applications
• Site preparation
• Small construction projects
• Frequent changes between compatible attachments

Spring-Assisted Attachment System

The spring-assisted locking mechanism is designed to make attachment changes more convenient by helping engage the mechanical locking components without requiring a hydraulic locking system.

Depending on the excavator and attachment combination, the coupler geometry may also increase the effective digging depth by approximately 6" (150 mm).

Actual digging depth and operating geometry will vary according to the excavator, attachment, coupler configuration, and working conditions.

Durable Construction

The coupler incorporates reinforced pivot and locking components designed for repeated attachment changes during suitable operating conditions. The mechanical design avoids the need for hydraulic lines or hydraulic cylinders for the locking mechanism.

Regularly inspect the spring mechanism, locking components, pins, pivot points, and attachment connection before operation.

Compatibility

The CAEL Spring-Lock Attachment Coupler is intended for compatible 1–1.8 ton mini excavators with:

• 25 mm mounting pins
• 90 mm pin center-to-center spacing
• 92 mm dipper gap
• Compatible mounting geometry

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

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