CROSS-REFERENCE TO RELATED PATENT AND PRIORITY
[001] The present application claims priority to Indian Patent Application No 201921014891 titled “Manual cable tray forming jig” filed on April 12th 2019, the entity of which is hereby incorporated by reference.
TECHNICAL FIELD
[002] The present disclosure in general, relates to a field of a cable tray. More particularly, the present disclosure relates to a system and method facilitating the cable tray bending.
BACKGROUND
[003] Generally, cable tray refers to a structure, used in an electrical connection for holding electrical cables. The cable trays are being used in power stations and large industrial plants to support cables as an alternate to using conduit. Use of cable tray system facilitates upgrading, expanding, reconfiguring, or relocating networks. Normally the cable trays are straight with no bends and curves. To achieve bending of the cable trays the process involves cutting and reattaching the parts of the cable trays at various angles. Thus, the commonly known processes of the cable tray bending demand large work force or complex machineries with skilled operators. Further, the conventionally known systems or infrastructure used for bending cable trays are not cost effective and process executed by such conventionally known systems are time consuming.
[004] Other conventionally known systems include hydraulic bending system with three roller that are motor driven and hydraulically adjustable. However, machines used in the hydraulic bending system are electrically powered and suitable for one of a medium bending or largescale bending, but the machines are prone to higher maintenance and consumes cost and require more time for operation. Since machine is bulky in physical appearance and works on electrical power, relocation of such hydraulic bending from one site to another may be very challenging.
