Excavator rotating quick couplers are usually called "Rotating Quick Coupler" or "Quick Hitch with Rotation" in the field of construction machinery. Some products are also called "universal quick-change connectors" or "hydraulic wrists" because they have universal rotation functions. The following is a detailed description of its core features and application scenarios:
Core functions and advantages
Quick switching of attachments
The installation and removal of attachments such as buckets, breakers, and hydraulic shears can be completed in seconds through hydraulic or mechanical structures, significantly improving work efficiency. For example, buckets and breakers can be quickly switched in municipal construction to reduce equipment downtime.
360-degree rotation function
After integrating the rotation module, the attachment can be freely rotated in the horizontal direction (usually ±360°) to adapt to narrow space operations or complex material handling requirements. For example, in mining, the angle of the hydraulic shear can be adjusted by rotation to improve cutting efficiency.
Tilt operation capability
Some models support ±40° tilting around the X-axis to further enhance flexibility. For example, when clearing ditches or trimming slopes, the attachment angle can be optimized through tilting operations to reduce the need to move the excavator body.
Safety protection design
Equipped with hydraulic lock, safety spring or mechanical and hydraulic dual protection device to ensure that the attachment will not fall off when the cylinder is depressurized, reducing the risk of high-altitude operations.
