DEVELON/DOOSAN Hydraulic Quick Coupler for Excavators
DESCRIPTION
TECHNICAL PARAMETER
The DEVELON/DOOSAN Hydraulic Quick Coupler is tailored for excavator operations, built to withstand demanding working environments. It is constructed from extra high strength (EHS) steel and abrasion-resistant (AR) steel to ensure maximum durability, with manufacturing processes strictly compliant with ISO 9002 standards for reliable quality. To enhance operational safety, it features a dual-stage release circuit design, and a pressure signal system that restricts attachment release only to secure positions, preventing accidental hazards. The operator control panel integrates seamlessly without requiring any modifications to the excavator cab interior, simplifying installation procedures. Additionally, it supports flexible operational conversion—operators can easily switch from hydraulic to manual mode—and its reverse configuration function enables compatible use with reverse-configured attachments, meeting diverse work needs.
