30ton double girder overhead crane electric overhead travelling
system
General description of double girder overhead crane
Double girder overhead crane is mainly used in inside workshop. It
is diveded into two working classes: A5 and A6 according to the use
grade and load-up condition.There are three kinds of method for
entering the platform of cab from the side, from the end and from
the top. The figure is the side entrance.The cab can be either
fixed at the left end or at the right end; the figure shows tat the
cab is fixed at the left end.Safe side wire or angle iron can be
used for electric conduction of the crane;
