Excavator quick couplers, also commonly known as excavator quick connectors, hydraulic quick couplers, or excavator quick-change devices, are referred to as “quick couplers” in the industry. Their core function is to enable the rapid connection and disconnection of excavator attachments through hydraulic control, eliminating the need for manual bolt removal. This significantly reduces attachment switching time and is compatible with various excavator attachments such as buckets, hydraulic breakers, pile breakers, and excavator hydraulic shears. They are widely used in construction, mining, and municipal engineering projects. Compared to traditional manual connection methods, quick couplers improve switching efficiency by over 80% and offer safer operation, effectively reducing labor intensity. YG specializes in the research and development of construction machinery attachments, and its excavator quick couplers are compatible with multi-ton excavators and available in various models, providing solutions for construction teams to improve operational efficiency and reduce labor costs.

Frequently Asked Questions about YG Excavator Attachment Quick Couplers
A: It fits most mainstream excavator brands on the market. The interface uses a standardized design, and both mini excavator quick couplers and heavy-duty types support customized interfaces, allowing for compatibility without significant modifications.
A: Choose based on the excavator’s tonnage: 1-6 tons for mini type, 10-25 tons for standard type, and 30 tons and above for heavy-duty type; choose between hydraulic automatic type (high efficiency) or mechanical manual type (economical) based on your work requirements.
A: The hydraulic type uses a hydraulic cylinder to drive the locking pin, allowing the operator to operate without getting out of the cab, resulting in higher efficiency and safety, but at a higher cost. The mechanical type requires manual operation of the screw or pin for locking, which is less expensive but takes more time to change and requires manual assistance.
A: You can connect almost all types of excavator attachments, including hydraulic breakers, hydraulic shears, log grapples, rippers, compactors, and even specialized tools like pile breakers, enabling multi-purpose use of a single machine.
A: The three most important points are: 1. The exact excavator model and tonnage; 2. The pin size and spacing of your existing or planned attachments; 3. Your preferred locking method (hydraulic preferred). Provide this information to YG, and we will help you select the precise model.
A: Maintenance is simple. The main tasks include: daily lubrication of all pins and bushings; regular inspection of locking pin wear and hydraulic oil leaks; and replacement of wear-resistant bushings every few hundred hours, depending on usage frequency. We provide detailed maintenance guidelines.
