Report TT.0534, Transport Engineering.
In this report it has been tried to study in a systematical way the stability
of rod-mechanisms, which are applied in turnable hoisting-cranes (which can
move their load in a radial direction). This has been done in a statical as
well as a dynamical way.
Firstly some considerations about cranes, rod-mechanisms and drives are
presented. After that the statical stability is considered.
In the second part of this report the movements of the crane are examined to
determine the dynamic consequences.
As an important research tool a computerprogram has been written for
a double-jib crane (four-link pin-joint system). The program can be used to
determine ca. 30 quantities in connection with the position of the head-jib;
some of these quantities are: coördinates, velocities, accelerations
