Safe Load Indicator

We are one of the leading manufacturers and suppliers of Safe Load Indicators in the market. Our Safe Load Indicator is a rugged instrument specifically designed for operating in the marine, humid and vibration prone conditions of jetty cranes. Simple to use, it accepts signal inputs from a load cell for load and an encoder for radius display. Any number of Load v/s Radius interlocks can also be provided as required, as per crane design. This system weighs and directly displays material weight, when lifted with any type of crane such as EOT, Gantry, Jib, etc. The indicator also has an annunciator test mode to check the proper functioning of the alarm condition audio-visual alarms. We offer Safe Load Indicator in a variety of specifications and can also customize according to clients specifications.

Attributes :

  • Full Software Calibration

How it Works ?

  • Actual load on the hoist exceeds 95% of the SWL or actual boom radius of the hoist exceeds 97% of max. Radius
  • Buzzer starts ringing and the respective ALM lamp starts flashing
  • ACK push button is pressed and the buzzer stops ringing but the lamp remains on
  • Goes off only when the respective actual load or actual radius reduces below the alarm condition values
