MTC Crane SLI

MTC Crane SLI

Safe Load Indicators (SLI) are designed for safe loading operation of Mobile tower cranes.

During the operation of a tower crane without SLI, the operator & signalman to manually estimate approx weight of the load to be lifted and radius at which the load is to be handled. Most of the time these rough estimations result in handling issues or crane can be put into very high risk of overloading.

Safe Load Indicators (SLI) are designed for safe loading operation of Mobile tower cranes.

During the operation of a tower crane without SLI, the operator & signalman to manually estimate approx weight of the load to be lifted and radius at which the load is to be handled. Most of the time these rough estimations result in handling issues or crane can be put into very high risk of overloading.

To manage these issues, cranes are equipped with SLI system which monitors the lifted load in closed loop control and restrict the trolley movement beyond the limits thereby safe operation of crane can be assured even if the operator makes wrong assumption.

The SLI prevents the crane from over loading at any point according to the OEM load chart and warns (audio & visual) the operator when 80% of rated load achieved at the current trolley position. Also the operation speed is brought to slow speed automatically. When the load saturation (100%) reached at the current trolley position then SLI stops further operation of crane in unsafe directions with audio and visual indications.

Our SLI Design directly interface with the crane controls thereby even if there is a failure of the crane trolley & hoisting limits, the SLI will ensure and safe operation of the crane.
