What is a Semi-Gantry Crane? A semi-gantry crane is a type of overhead crane that combines elements of both gantry and bridge crane designs. Unlike a full gantry crane, which typically has both legs mounted on tracks, a semi-gantry crane has one end supported by a track system while the other end is fixed to a building structure or another support. This design allows for a versatile range of lifting and moving tasks while offering the advantage of reduced space requirements compared to a full gantry system.
Definition and Unique Features of Semi Gantry Cranes
Semi-gantry cranes are characterized by their asymmetric support structure. The crane's frame consists of a single side rail or track system, which supports the crane's hoist and trolley. The other side of the crane is typically supported by a wall-mounted rail or an overhead structure, allowing it to cover a significant span with a more compact footprint. This design is particularly advantageous in environments where space is limited or where a full gantry system would be impractical.
Key features of semi-gantry cranes include:
- High Lifting Capacity: Capable of handling a wide range of weights, from light loads to heavy materials.
- Versatility: Suitable for various lifting and moving tasks in diverse environments.
- Cost-Effectiveness: Generally more economical than full gantry cranes due to reduced structural requirements.
