Product Overview

The Double Safety Lock Quick Coupler is developed for excavators that require safer attachment changes and reliable connection performance during daily operations. It allows operators to quickly install or remove buckets, breakers, and other excavator attachments without manually removing pins, helping reduce attachment replacement time on construction sites.

Unlike standard quick couplers, this model uses a double locking structure to add an extra layer of protection between the coupler and attachment. The primary lock secures the attachment during operation, while the secondary safety mechanism helps prevent accidental release caused by improper engagement or harsh working conditions.

Our products are CE certified and can be widely used in construction, earthmoving operations, and other professional excavation applications where reliable attachment connection safety is required.

Safety Design & Performance

Double Lock Protection System

The dual safety locking system creates two independent locking points between the excavator and attachment. This design reduces the risk of unexpected attachment movement and provides additional security when working in demanding environments.

Durable Steel Construction

Made with Q355 manganese steel, the coupler delivers a strong load-bearing structure while maintaining long-term durability. The material selection helps the quick coupler withstand frequent attachment changes, impact loads, and outdoor working conditions.

Efficient Attachment Replacement

The hydraulic quick connection system allows operators to switch between different attachments more conveniently. By reducing manual pin removal and installation time, it improves excavator utilization and minimizes downtime on the jobsite.

Wide Excavator Compatibility

Available for excavators from 1 to 35 tons, the double safety lock quick coupler can be matched with different machine sizes according to attachment dimensions and operating requirements, making it suitable for various construction applications.
