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.

Double girder overhead crane for walking on a roof is composed of box type bridge frame, lifting trolley, crane traveling mechanism, and electrical system. It is an excellent choice where high speeds and heavy service are required.

The double girder overhead crane is composed of a beam, a lifting mechanism, a trolley traveling mechanism, a crane traveling mechanism, a cabin or a manual controller and an electrical control system. The trolley can move horizontally on the track. This type of crane has many features, is lightweight, easy to install and maintain, and is typically used in manufacturing or maintenance applications. The cross beam is integral without welding, making the structure more reasonable and reliable.

Last year, SEVENCRANE began to enter the Russian market and went to Russia to participate in exhibitions.

The European double-girder bridge crane is a new type of double-girder bridge crane. Compared with ordinary double-girder bridge cranes, the NLH adopts FEM standards, has a more compact structure, more stable operation, and low noise.

The double-girder bridge crane has superior performance, compact structure, light weight, reliability and operation, and can meet various working conditions.
