Gantry cranes are the largest and most powerful cranes from the whole range of our production.
It consists of the following main elements:
metal structure of the bridge and legs;
electrical equipment, control system and safety devices of the crane;
hoisting devices - hook, grab, spreader, magnet, etc.
Metal structure is the main load-bearing part realized in two versions: box welded section of sheet steel or space truss of long profile. Based on a variety of criteria, such as sailing, loading mode, etc., our specialists are calculating all elements of the metal structure and selecting the optimal cross-sections.
Our load trolley is an analogue of overhead crane trolley or electric hoist. The main constructive difference is the arrangement of mechanisms for lifting and moving the trolley on the metal structure of the crane which increases the maneuverability and energy efficiency of the crane.
Electrical equipment, control systems and safety of the crane are developed by our specialists individually to ensure reliability of the gantry crane in conditions of all kinds of weather “surprises”. Since the gantry cranes operate in open areas, we provide anticreep system against storm and hurricane wind in the design of cranes.
To provide high speed and dynamics of mechanisms acceleration, our specialists developed a number of solutions in the field of electric drive, based on frequency converters and thyristor control panels.
