Induction Furnace Crane Spares

The LAWA Lever Limit Switches are used for prevent over travel or over traverse on power & control circuit upto 500 V.A.C. 50 cycles / second and 40 amps current rating.

LAWA Limit Switch normally remains closed and cuts off power to stop the motor of the crane. The Limit Switch operates when it reaches a predetermined position when the lever is moved over a projecting member fixed on the girder.

The LAWA Master Controller contact body is made of hight grade melamine suited for heavy duty, non tracking and capable of withstanding heavy arcing. The contacts have maximum current capacity of 40 amps at 500 V.A.C. The contact tips are made from high grade silver cadmium alloy. We also provides Induction Furnace, Induction Furnace Spares, Induction Furnace accessories, Induction Furnace Spares & accessories.

The LAWA Resistance Boxes are designed to meet requirements for both A.C, & D.C. for speed control and developing starting torque. The specification complies with BSS 5871: 1957. The basic types are STAINLESS STEEL and PUNCHED STEEL. Resistance boxes are suitable for max. temp, rise of 375 °C as stipulated in BSS standards.

The LAWA Rotary gear type Limit switches are used on control / Power circuit of reversing drives so as to limit their rotation/movement within a predetermined position. The function of the Limit Switch is to stop the mechanism of drive at the extreme forward/reverse positions. The contacts of Lawa Limit Switches are 40 amps rated at 500 volts A.C. The Limit Switch can be provided with 2 NC contacts or 4 NC contacts or (2 NO + 2 NC) contacts as per the requirement.

The LAWA Flexible Geared Couplings are suitable for over Coming the following type of misalignments.

Parallel Offset: Where axis of connected shafts are parallel but not within the same straight line.

Angular: Axes of shafts intersect at the centre of coupling.

Combined Angular : Offset axes of shafts are neither parallel nor do they
intersect.

Hubs of LAWA Make Couplings are machined from EN-9 Steel forgings to close tolerances for accurate alignments and proper balance.

The LAWA Electro Hydraulic Thrustor Brakes are suitable for 400/440 Volts. 3 phase A.C. Supply for a wide range of drum sizes from 100 mm to 600 mm dia. The Braking pressure to the Shoes is transmitted from the springs by means of an extremely rigid and simple lever / tie rod mechanism.
