What's wrong?
The Load Moment and Area Protection system on 2014-2017 Altec AC40-152S cranes is an electronic operator aid. It shows load chart information on the crane display so the operator can compare the planned lift with the chart values for that boom position and setup. The printed load chart remains the controlling operating reference.
On affected cranes, the LMAP software contains incorrect load chart values. That means the display can disagree with the printed chart, giving the operator a value that does not match the crane's approved lifting information. The issue is in the software loaded into the display system, and the display also shows the software revision number used to identify it.
The operator will not get a separate failure warning before the incorrect value appears. The sign to watch for is a mismatch between the printed load chart and the LMAP display. Use the printed chart as the primary operating reference and have Altec update the software.
