Double girder bridge cranes

Double-girder bridge cranes are in the widest range suitable for any crane need. They can be built up to a span of 40 m and a load capacity of 160 tons using the crane components of StahlCranesystems GmbH.

This type of crane is especially recommended for high-intensity use. If required by the customer, it can be equipped with sidewalks and platforms along the main girder, which ensure access to all points of the crane for inspection and maintenance without need of auxiliary equipment.

Bridge cranes usually run on a runway placed at two sides of the building, on brackets mounted on the walls, or on pillars serving to hold the runway. This arrangement is called top-running crane (ZL).

The drive systems of the cranes can be delivered according to our customer’s needs with two-speeds or even continuously variable speeds.

Dependend on the connection between the endcarriage and the girder we distinguish "top-connected" (ZL-A), "bottom-connected" (ZL-B) and "mounted" (ZL-C) design. The choice of layout helps to flexibly adapt to the requirements of the space to be craned and the possibilities of the building.

• 

  The advantage of the ZL-A construction is the small distance between the rail crown level and the top point of the crane, which makes it possible to install a crane with a higher load capacity in case of a small distance between the crane runway and the roof structure.

• 

  The advantage of the ZL-B construction is the best possible use of the hook's side positions in addition to the low construction height of the crane.

• 

  The ZL-C layout makes it possible to achieve the highest possible lifting height with low crane runway levels and high internal heights.
