Description: 
Spring-operated cable reeling drums (CRD) are powered with springs and have an automatic rewind feature which provides an extremely simple way of supplying powerto machines such as cranes and hoists. These cable drums are used for both AC and DC applications. These reels recover and store the cable in multiple layers on the drum. Standard reels are supplied for the cable fed in the clockwise direction, when viewed from the slipring side. The same can be provided for anti-clockwise feed of cable also. These reels are extremely simple to mount, and can be mounted on the structure with the help of a supporting flange. If no suitable structure is available, then a bracket can be connected to the flange and this can be fixed to the floor or tray, etc. The springs used in these reels are manufactured from the highest quality materials and are of clock spring type. A wide range of characteristics can be obtained by assembling these springs singly or in series or in parallel. All the power sliprings are designed for 600 V AC operating voltage. Spring-operated cable reeling drums can also be supplied with geared rotary limit switch arrangement.
