Loadmoment Limiter for Lattice Boom Cranes LBC-1

 

Ideal for:

 

•      Truckmounted Lattice Boom Cranes

      •      Crawler Cranes

     

LBC-1 is the most economic State-of-the-Art system to realize a loadmoment limiter for lattice boom cranes.

 

The LBC-1 system consists of sensors for forces and the boomangle and a control (PLC). The multi-colour graphical display shows the important LMI parameters such as the actual load, boomangle and radius. The loadmoment is shown as a digital number in percent but also with an analogue bargraph in trafficlight colours. On the left side, the green field shows, that everything is in right order. At 90% loadmoment, it turns to yellow as a prewarning. At 100% loadmoment, the red fiel will be lit as an indication that LBC-1 now

stopps the dangerous movements of the boom to avoid any further increase of loadmoment.

 

Both, controller and display are programmed in World-Standard IEC 61131-3 language CoDeSys ®.

 

LBC-1 fulfils its safety function by activating or shutting down crane functions via digital outputs. For instance, when the loadmoment is 100%, booming down or lifting the load is blocked whereas lowering the load and booming up is enabled. 

LBC-1 can be linked directly to the crane controls and other systems by CANBUS or by optional analogue outputs with 4…20 mA output current.

 

LBC-1 comes as a plug-and-play solution and can be calibrated without any special tools simply on the screen in a very short time.
