About Load Moment Indicator

The Klug Avalon Mechatronics Pvt Ltd offers a reliable load moment indicator (LMI) / rated capacity indicators (RCI) solution which is also called a safe load monitoring system, for measuring crane lifting capacity & makes the lifting operation smooth, risk-free & safe for the crane and the crane operator. This crane LMI system is mounted in the cabin area to be accessible for the crane operators. Along with supported sensors like angle boom sensor, load sensor, a2b switch sensor, etc.- the final lifted capacity is displayed in the load moment indicator and assures the crane operator to be work within safe load lifting capacity as compared by the crane rated capacity. It also comes to alert the operator with a huge noise buzzer, if the lifting capacity is overloaded with the rated capacity.

At the time of primary installation, the load moment indicator system is configured as per the load chart provided by the crane manufacturer.

The smart Digital Safe Load Indicator Display comes with the following indication:

  • %LM: Shows the Currently operated Duty boom hook no.
  • Over hoist Section: This shows the working Angle between base and boom.
  • Out Trigger: This shows the length between boom head and base.

The Automatic Safe Load Indicator System Comes with Supportive Switch Buttons for Activities:

  • Emergency Stop Button: Shows the Total Length between Boom head & Base
  • Bypass Button: Shows the Lifted Load of the Crane.

The LMI Control Unit is able to receive the accurate signal from various sensors to calculate and generate the final result over the LMI display. In some condition when the lifting capacity is exceeded the defined rated capacity, then this device just lock the crane machinery until the operator press the bypass button located at the load moment limiter display unit or until the operator back to safe mode by adjusting the situation (angle/boom length/ load)

Following are the conditions when the cut-off situation activates the system and lock the machinery is:

  • Radius / Low boom angle
  • Weight Overload situation
  • A 2 B Limit Crossover signals
  • Min. radius / High boom angle

What is an SLI System?

Safe Load Indicator is a safety control unit mounted in the crane’s cabin to alert the operator if the lift is exceeding the safe operating range of the machinery

Is it Necessary to install SLI System in our Crane?

Yes, Its necessary and important to avoid any future accident while working with materials without knowing the actual load and rated crane capacity.

What if We Have Old Crane dose your SLI System Support our Crane operation?

Yes Off course, As per your Crane capacity chart we will make a custom SLI system that match your Crane and Its Operation

We have pre-installed SLI System, still its need to update?

Yes, sometime pre fitted safety System are inadequate to protect hence we recommend to talk our Crane safety system officer and know the best suited solution for your crane.

What is an Anti-two Block Switch?

Over-hoist Switch measures the distance between the lifting hook block & Head of the boom crane, which avoids the collision between them and alerts the operator by sending signals via the SLI.
