LOAD MOMENT INDICATORS (LMI)Load Moment Indicator (LMI) is a system which aids the Tower Crane Operator by sensing the changing moment on the Crane structure.
Using various high accuracy sensing devices, the LMI monitors all measurements of Tower Crane load, hoist, jib and slew or boom angle, and provides the operator with a continuous reading of the crane’s positioning. The readings continuously change as the crane moves through the motions needed to make the lift. If hazardous conditions are approached, the LMI is designed to warn the operator by sounding an alarm and illuminating a warning light. LMI does all that calculation for Crane Operator. Therefore, with the effective assistance from the system, it improves the safety & productivity of the construction lifting activities.
System’s function includes:
o Display real-time operating situations with graphical display
o Control and alarm of torque limit
o Radius and height limit
o Working and overloading records
o Configurable situational alert by the system
o 2/3/4 Selectable Parts Line
o Microprocessor & Circuit breaker output control
o Current date and time display
o Setting up of Restriction zone
o Wind speed and alarming system
