• ELECTRICAL SUPPLY
  
  • Operates at 415V, 3-phase, 50/60 Hz by default.
  • Compatible with other voltages up to 440 VAC, 3-phase upon request.
• CONNECTIONS
  • Thrusters function equally well in either direction of rotation.
  • Supply lines can be connected in any R-Y-B phase sequence.
• OIL REQUIREMENTS
  • Thrusters are delivered without oil to prevent spillage during transit.
  • Use Transformer Oil (IS:335) for optimal performance.

Resistance boxes are critical for modifying the performance of Slip Ring Electric Motors used in EOT cranes, steel rolling mills, cement plants, and more. They regulate speed and starting torque while limiting starting currents. They are also employed as Dynamic Braking Resistors in VVVF AC drives.

The Rotary Geared Limit Switch (GRLS) from Elite Cranes is designed to cut off the power supply when moving loads reach the extreme end positions within their working zone, ensuring safety and precise control.

Operation

• The switch operates through contact elements activated by rotating cams.
• These cams, mounted on a cam shaft, rotate at a fixed speed ratio with the drive motor shaft.
• The cams can be precisely adjusted to trip the motor supply and halt motion at the desired point in the travel range.

Application

Rotary Geared Limit Switches are ideal for reversing drives in various industrial mechanisms, including:

• Hoists and Winches
• Rolling Mills
• Steel Plant machinery such as Coke Ovens and Feeding Systems

Elite Cranes’ Lever (and Counterweight) Operated Limit Switches (LLS / CWLS) are designed to control the change-over contacts of motors on moving equipment. The limit switch is actuated when a cam, moving with the load, triggers the lever, rotating the cams on a square shaft and operating the NO/NC contact elements for precise control.

Operation

• The switch utilizes one or two contact elements, which are activated by rotating cams fixed on a square cam shaft.
• The cam shaft is turned by a lever or counterweight, ensuring smooth operation
• Contacts operate from a central neutral position, providing reliable switching at both ends of the travel range.

Technical Data

Elite Cranes Flexible Geared Couplings efficiently address the following misalignments:

• Parallel Offset: Parallel but misaligned shafts
• Angular: Shafts intersect at the coupling center
• Combined Angular: Neither parallel nor intersecting shafts

Machined from EN-9 Steel forgings, our couplings ensure precise alignment and balance for superior performance.

Festoon cable trolleys support and guide cables along runways or bridges, enabling smooth and efficient cable management for long runs.

Features:

• Four wheels with a pivoting saddle support
• Suitable for flat or round cables
