Key Features

Die-cast body and lost wax components ensure durability and precision.
Waterproof body design for enhanced reliability in harsh environments.
Fully automatic safety lock compliant with EC standards for operator safety.
Permanent and automatic gap compensation maintains optimal attachment fit.
No modification required to the genuine digging power of the excavator.
Compatibility with former bucket ranges allows easy adaptation.
Mini bucket width options available for precise fitting.

Hydraulic Quick Hitch System

The hydraulic quick hitch (QA H series) includes an optional hydraulic control kit. It offers significant operational advantages:

Quick change capability increases speed by approximately 50%.
Safety improvements of about 60%.
Operator convenience as the driver does not need to leave the excavator to change attachments.

Mechanical Quick Hitch System

The mechanical quick hitch (QA M series) features:

Unlocking by power amplifier for ease of use.
Similar durability and safety features as the hydraulic version.
Note: Ears (attachment points) do not have adjustable bearings.

Recommendations and Best Practices

Ensure compatibility of quick hitch model with excavator specifications and bucket sizes.
Use the hydraulic control kit option for enhanced operational efficiency and safety.
Regularly inspect the automatic safety lock and gap compensation mechanisms to maintain performance.
Follow EC safety standards during installation and operation.
