MAGCO - DOUBLE GIRDER BRIDGE
CRANES form a major chunk of orders received by
Magco Cranes annually. As a result, the company
has successfully managed to refine this particular
product over time to reflect changing customer needs and
evolving technology.
The figure above shows a Double Girder Bridge crane with
Auxiliary Hoist. Magco Cranes manufactures
Double Girder Bridge cranes without the auxiliary
hoisting feature also. Depending on the spans of the
factory sheds, the Double Girder Bridge Crane can come
either with a Single Drive system or a Twin Drive
system.
Magco Cranes also makes cranes that have a cabin control
feature as is seen in the picture on the left above.
Depending on the Safe Working Load of the crane, the
Double Girder Bridge Cranes have either a carriage type
travelling mechanism or a bogey type travelling
mechanism.
