Gantry cranes in their design resemble bridge cranes installed on their own supports. Gantry crane has the following device:
- the metal structure of the bridge itself and its supports;
- cargo trolley;
- a set of electrical equipment, control systems and safety devices;
- devices for grabbing goods - hooks, spreaders, magnets, etc.
Steel structure of the bridge
It carries the bulk of the load. The load-carrying parts are designed in several versions: sheet steel with a box-shaped welded section or a profiled section of a spatial shape. Based on many criteria, for example, windage, degree of load and more, specialists calculate all components of the metal structure and select the optimal cross-sections.
Cargo trolley
is similar in design to those used on overhead cranes or electric hoists. The main design difference is the location of the lifting mechanisms and the movement of the cargo trolley on the metal structure. The trolley is maneuverable and energy efficient.
Electrical equipment
All control and safety systems for a gantry crane are best designed individually to ensure that the crane remains in good working order in almost all weather conditions. Electric gantry cranes mainly operate in open areas, so it is worthwhile to provide anti-theft systems in their design against hurricane and gale winds.
In order for the mechanisms to work at maximum speed and dynamically accelerate, specialists develop innovative solutions in the field of electrical technologies. The electric drive is developed on the basis of a frequency converter and special control panels that are installed directly on the gantry crane.
