Mechanical Quick Coupler for 120t Excavators | China Factory Suppliers
The Pin Grab Type Mechanical Quick Coupler serves as a high-efficiency "mechanical wrist" for your excavator, enabling the rapid transition between various attachments in a matter of seconds. Designed for versatility and ease of use, this coupler eliminates the time-consuming process of manual pin removal, significantly boosting operational productivity on construction and demolition sites.
Engineered for excavators ranging from 1 to 20 tons, our mechanical quick couplers prioritize cost-efficiency without compromising structural integrity. By integrating a specialized safety pin system, we ensure a secure lock between the arm and the tool, providing a reliable and economical solution for contractors looking to maximize the multi-purpose capabilities of their machinery.

Frequently Asked Questions
The primary advantage is the drastic reduction in tool changeover time. It allows operators to switch attachments in seconds from the cab, reducing downtime and increasing the number of tasks a single machine can perform per day.
We use 45# steel for standard pins, with options for 40Cr and 20CrMuTi for high-stress applications. The body is available in Q355, Q690, NM400, and high-strength Hardox 450 steel.
The safety pin acts as a secondary mechanical lock. In the event that the cylinder fails or the fixed function malfunctions, the safety pin physically blocks the attachment from falling off, protecting personnel and equipment.
This specific model series is optimized for 1-20 ton excavators. Using it on larger machines significantly increases safety risks and may lead to structural failure; we recommend selecting a model matched to your machine's tonnage.
Yes, our couplers are designed to be compatible with various global brands of excavators and backhoe loaders. We provide custom fitting to ensure a perfect match with your specific arm dimensions.
Given the high-stress nature of construction and mining, we recommend a daily visual check of the safety pin and a weekly inspection for wear on the pins and bushings to ensure optimal performance and safety.
