The main structure of the double girder overhead crane consists of a box steel with two beams or a profiled steel with a mobile electric carriage. The lifting system consists of a winch or a wire rope hoist, running on the beams as required, allowing horizontal movement.

מנופים עיליים כפולים offer higher load capacity with minimal deadweight. The lifting hook can be raised between the two crane beams, allowing maximum lifting height.

Modular cranes design engineers can design double beam bridge cranes with spans up to 40 meters with versatility and flexibility to meet specific requirements. Faster long-travel speeds, maintenance platforms, crane units with access platforms, service platforms and auxiliary hoists are all features that can be easily implemented.

Capacity: Load capacity is often the main reason for selecting a double beam bridge crane. If loads exceeding 15 tons need to be lifted in a constant duty cycle, a double girder overhead crane is a cost and space-efficient solution.

Improved hook height: The 10 ton double girder overhead crane features a trolley that travels on top of the bridge, which improves the hook height. This enables the operator to lift higher and longer objects and materials within the work area compared to a single girder bridge crane with an underslung trolley and hook.

Auxiliary hooks on each girder: Additional hooks can be added to a single girder to add multiple lifting points to your bridge crane. These hooks can bypass each other as they are not on the same girder.

Longer spans: The 10 ton double girder overhead cranes can also span longer distances as the parallel girder design has greater combined strength than a single girder.
