The multi-functional rope grab pulley combines a multi-functional rope grab, a high-efficiency pulley and an integrated sling ring, facilitating traction and ascent. Based on V-slot cams, it is designed to handle rescue loads while providing force-limiting overload protection, and is suitable for 10-12mm ropes. Compact in structure, diverse in function and easy to use, it is suitable for a variety of technical applications in individual and team rescue and rope operation systems. It replaced multiple devices, simplifying training and operation. By integrating multiple functions and the built-in force-limiting function, it provides technicians with a higher degree of traction and ascent safety and efficiency.
