RESISTANCE BOXES
The SUSHIL’S make resistance boxes are designed for both AC and DC applications. Stainless steel grid resistance boxes are used in E.O.T Cranes, Rolling Mills, Power Plants, Steel Plants, Cement Plants, Mines etc, These are used for speed controlling of slipring motors and developing of higher starting torque. 

Resistance Boxes are designed to BSS / NEMA / IEEE standards and these boxes are suitable for a maximum temperature rise of 375◦ C as stipulated in BSS standard.

 PUNCHED GRID STEEL RESISTANCE 
These type of resistance boxes are made of stainless steel sheet and grids are completely shock and vibration proof to work in worst operating condition.
Please provide following details with your enquiry :

  • Capacity of motor (KW/HP).
  • Rotor Voltage of motor.
  • Rotor current of motor.
  • No. of steps required.

TWO WAY SHUNT LIMIT SWITCHES 
Two way limit switches is used to prevent over travel or over traverse. The tipped contact of limit switch is normally closed and supply power to contactor coil in control panel and will cut off power and stop the motion when it reaches a predetermined position, when the lever is moved over projecting member fixed to the gantry. Limit switch contacts are automatically reset when the lever return to “ZERO” position due to spring action.

 


GEARED LIMIT SWITCH FOR HOIST DRIVE
Limit switch hare a geared ratio of 36:1, 48:1 or any required ratio. The limit switch has two contacts, one contacts cuts – off power supply to the coil circuit of the hoist and the other contacts cut - off power to the down. Switches are completely dust and water proof.

 

 


HOIST LIMIT SWTCH
These type of limit switch are used to prevent over hoisting. When the snatch block reaches the highest position, the weight pulling the lever down is moved up on the snatch block. The lever is therefore released and the two contacts cut off power two phases of motors there by stopping the hoisting motion.

 


MASTER CONTROLLER 
Master controller are used for operation of contactors equipment for controlling E.O.T cranes and rolling mills drives. The controllers are made in dust proof enclosure.
Technical data:-

  • Body material : steel sheet
  • Degree of protection : IP-41 / confirming to IS – 13847 (1) 1993.
  • Mounting position : horizontal / vertical
  • Contact material : silver / Cadmium
  • Rated voltage insulation : 500 V AC
  • Frequency of operation : 1000 switching per hour

ELECTRO HYDRAULIC THRUSTOR BRAKE 
It is a heavy duty brake designed to withstand the severe duty conditions imposed by heavy duty machinery in various industries.

THRUSTOR : The electro hydraulic thrustor consist of a cylinder fitted with oil and having a centrifugal pump at the bottom of the cylinder. The centrifugal pump is driven by a 3 phase fractional horse power continuously rated motor. The special designed radial impeller permits operation of the pump in either direction  of rotation. The motor is mounted on the top of the oil cylinder.
