Negative load limits
Because of the design of the boom system of the crane - particularly because of the arrangement of
the sliding elements - negative loads (e.g. pushing with the boom system) are extremely unfavorable
for the crane. The Paltronic 150 contains two load limits that restrict the negative load of the boom
system to a set limit. These are one limit for the boom system of the crane, and one for the outer boom
system of the fly-jib.
Examples of negative load limits:
If a limit is reached, all crane movements that would increase the negative load on the boom system
are blocked.
The crane movements that are still possible are indicated on the Paltronic 150 display unit.
