Stainless Steel Punch Grid Resistance Box is designed to meet requirements of A.C & D.C. Application for E.O.T. Cranes, Winches, Rubber Mills, Flour Mills, Coal Mines, Cement Mills, Power Plants, Conveyors, Coke Oven, Blowers etc. For Speed control and developing starting torque. Stainless Steel Punch Grid Resistance Box is manufactured by Rolex Industries.
Rolex Industries also manufactures EOT Crane Control Equipments like Thruster Brakes, Resistance Box, Limit Switches, Thrusters, etc. Stainless Steel Punch Grid Resistance Box consist of Grids Punched from Nickel Chromium Steel Alloy Sheet. These grids are shock and vibration proof. These resistors are specially suited for Steel mill duty. Coal mines etc. These resistors are available in a wide range of Current ratings from 7 Amps to 800 Amps continuous. The series connection between adjacent grids is by means of copper jumpers. The resistors, after overloads of moderate duration become red hot but no damage is caused and retains their shape after overload disappears..
