6.2 Weighing the truck crane
Weighing error The most precise method for determining the total weight of the GMK5150L
is to use calibrated scales of appropriate capacity and a weighbridge on
which all the wheels of the truck crane can stand at the same time.
All other weighing procedures are subject to various factors which can lead
to weighing errors. This Operating manual describes a procedure by which
the greatest number of sources of weighing errors can be avoided. Also
observe all the instructions provided by the manufacturer of the scales.
If multiple individual scales are used, allowance must be made for the fact
that the axle groups are hydraulically coupled. For this purpose, you will
need wheel load scales of sufficient capacity and size.
– Determining the total weight
The weights of all the axle groups belonging
to the crane must be recorded at the same
time in a single weighing procedure. In addi-
tion, only one set of scales may be used per
axle group on each side of the vehicle.
The GMK5150L has two coupled axle
groups (
A1 to A2 ) and you will require
four wheel load scales ( W1 to W4 ).

Defective measurement of the axle loads and total weight.
When determining the axle loads and total weight, do not use individual
dial scales. If individual dial scales are used to weigh a truck crane, this will
lead to incorrect, unreliable measurement results.
