L68B1 Mast Section ring collector, a tower crane accessory for safety
The cause of tower crane accident is mostly caused by the lack of safety measures. Now we know a tower crane accessory, ring collector, which plays a safety role.
The ring collector on the tower crane is used to send the power from the fixed part of the tower crane to the rotating part, which is fed by the ring collector. The number of rings depends on the requirements of the tower crane of the electrical system.
The structure of ring collector is similar to the slip ring and brush mechanism of wound induction motor. Installed under the tower body, it can rotate with the tower body. The brush 3 is fixed on the base of the crane. The collector ring 2 and the brush 3 are respectively connected with wires. The brush 3 is closely attached to the collector ring 2 by the tension of the spring 4 to connect the power supply.
During the use of the ring collector, the dust and dirt on the collector ring and the brush shall be removed frequently, and the pressure of the brush and the wear of the brush shall be checked frequently, and the brush shall be replaced if the wear is too large. Keep the brush in good contact with the collector ring.
