                                       SUSPENSION CRANE

   Suspension crane ran under the tracks. Designers can create either a single beam and dual-beam,
               as appropriate, regarding the use of weights. And the width of the building. As mentioned already
               described in the section of the overhead crane that runs on the raceway. But for all the differences
               that need to be brought down overhead crane hanging rails running under it. These cranes are suitable
               for use with industrial buildings, some of which want to use the wide area as much as possible. Building
               such a large aircraft repair garage. And assembling structural parts with large dimensions. To use
               components, the installation of separate pieces can be set up by a pair of rails ran into a pole and 2 
               above or installing multiple. Running rails mounted on the roof. Thus on the above image The roof is
               designed to create a powerfully stretched by the weight of the crane movements.

                    Suspension crane ran under the tracks. Suitable for use weights ranging from 1 to 12.5 tonnes is not
               very hard for the plant design raceway hung on a pole attached to the load-bearing factory direct. And
               weights up to 2 tons in the raceway hung from the roof fixing is very broad. And should have a width
               between raceway operators. Each of the raceway not more than 20 meters and for cranes of this type.
               Crane is widely used to get a particular job. Which is not used much. If the normal use compared to
               overhead crane running on rails, it can be easier. Creating a cheaper budget And are more 
               secure It is not necessary to create this type of crane used to it.
