MIPEG Rated Capacity Indicators

MIPEG has been a world wide market leader for decades. The MIPEG 2000 crane monitoring system brings not only enhanced standards of safety to crane operation, but also records historical lift information to support more cost efficient crane maintenance planning and slewing changeout deferral.

Load sensors at the boom tip measure both the static load and the peak load during each lift and pass the information to the central computer. Both main and auxiliary hoists have load sensors fitted so that lift information is recorded regardless of which hook is used.

The moment sensor on the A-frame measures the crane over turning moment - the stresses on the bearing and the pedestal - with this parameter also being passed to the central computer.

Simultaneously, the Inclinometer at the boom foot measures boom angle and translates this into operating radius before feeding this data to the computer. This allows the computer to constantly monitor the safe working load (SWL) at any given radius.

Outputs from the computer are fed directly to the in-cab display and audio warnings. The operator’s display can also be mounted remotely from the crane where no cab exists. The outputs can interface fully to the crane’s gross overload protection system, activating cut outs as required, typically boom out inhibit.

All this data, which is used in real time to protect the crane, its operator and all those within the vicinity of the lifting operation, can be recorded for subsequent download to a standard laptop.These records provide complete analysis (for each individual lift and cumulatively over the life of the crane) of the dynamic and static hook loads, over turning moments, radius, number of rope falls set, sea condition, lift duration and many other parameters. This information is invaluable in planning cost effective crane maintenance, based on actual crane utilisation and also in gathering information to guide upgrade or replacement strategies later in the crane’s life.

The MIPEG range also includes a rope speed indicator (RSI) which assists the operator when making ‘blind lifts’. The unit displays rope speed visually, with a bar graph, and audibly, using a buzzer, and has a reset button for zeroing height/depth display. The unit can also be configured such that outputs can control rope paid out and anti two block position.
