Excavator Quick Coupler - Color: Customized

Hydraulic excavator quick-change couplings utilize hydraulic cylinders for actuation, with hydraulic-controlled check valves ensuring locking and solenoid directional control valves managing disengagement and clamping. The cylinder's stroke length enables continuous adjustment of clamping range, allowing flexible adaptation to various working attachments. This quick-change coupling offers practical convenience, enabling operators to replace attachments without leaving the cab by directly controlling the coupling through pilot valves. Safety Features: AcA A Preventing accidental disengagement: Hydraulic quick-change couplings are equipped with reliable locking mechanisms such as safety pins and latches. These devices prevent unintended detachment during hydraulic system operation caused by vibrations or impacts. Accidental disengagement could lead to hydraulic fluid leakage, equipment damage, or serious injuries, while the locking mechanism effectively prevents such incidents. AcA A Pressure protection: Some quick-change couplings incorporate pressure protection systems. When system pressure exceeds the coupling's rated capacity, internal components automatically adjust or activate protective measures (e.g., safety valves) to prevent damage from excessive pressure, ensuring hydraulic system safety. Key Features:
1. High-strength materials compatible with excavators from 1 to 50 tons, offering both convenience and cost-effectiveness.
2. Electronic drive system in the cab allows operators to control quick-change couplings through electric power.
3. Anti-reverse valve protection: Each cylinder is equipped with an anti-reverse valve to maintain normal operation even when hydraulic and electrical circuits are disconnected.
4. Safety pin protection system: The safety system is configured according to the specific parameters of different excavators to ensure that the quick-change joint can still operate normally even if the cylinder is faulty.
5. Simple structure, easy installation and maintenance.
