Double Girder Gantry Crane

The Double Girder Gantry Crane is composed of two parallel main beams supported by four legs, which are structurally connected to the end carriages (headboards) responsible for the longitudinal travel of the gantry along the runway or rail system. The hoisting and traversing assembly—typically a trolley-mounted hoist—operates on the upper flanges of the two main beams, enabling precise lifting and lateral movement.

Multiple hoisting mechanisms can be integrated into the same gantry structure when operational requirements demand it. These units may operate in synchronized mode with the primary hoist to increase lifting capacity or function independently as auxiliary systems to enhance operational versatility and efficiency.

Single Girder Gantry Crane

The Single Girder Gantry Crane consists of a single main beam supported by either two or four legs, which are connected at their base to end carriages (endpieces) that facilitate the longitudinal travel of the gantry along the rail system. The hoisting unit—comprising the lifting and traversing mechanisms—operates beneath the main beam, typically via a trolley running along the lower flange.

Multiple hoisting devices may be incorporated into the same gantry structure when required. These units can function simultaneously with the primary hoist to support coordinated lifting operations or serve as auxiliary systems to enhance operational flexibility and efficiency.
