Counterweight Cable Reel
The counterweight cable reel is a mechanical device that automatically winds up the cable by using the principle that the weight is lifted to store energy. When the cable is pulled out, the cable reel is driven to rotate, thereby driving the coaxially connected wire rope reel to rotate, and the weight is lifted to store potential energy. The wire rope reel rotates, thereby driving the coaxial cable reel to rotate and coil the cable.
