Overhead Travelling Cranes and gantry cranes

Technical Specifications

Double Girder Overhead Travelling CranesDouble girder overhead travelling cranes are composed of lifting trolleys and end-carriages on two box girders which are obtained from sheet metal with welding processes. With standard production from 2 ton to 50 tons, and process cranes from 50 to 250 tons we count with effective solutions for wide spans and high lift capacities. Thanks to the maintenance platform available in one of the beams, maintenance and fault conditions solving are facilitated. Generally, the main energy supply is provided by the bus-bar system, and the lifting group power line is provided by the c-profile or IPN profile system.
Single Girder Overhead Travelling CranesSingle girder overhead travelling cranes consist of lifting trolleys and end-carriages on a steel construction made of box beams or prefabricated steel beams (HEA, HEB, IPN, etc.). It is generally preferred for low lifting capacities and short bridge spans. Although it is an effective solution for low headroom between the ceilings and crane runway, it is advantageous in terms of initial investment cost. Generally, the main energy supply is provided by the bus-bar system, and the monorail lifting group power line is provided by the c profile or the moving cable channel. This type is preferred in many areas of the industry like: manufacturing, assembly lines, paint booths and over-the-counter material loading.
Gantry and Semi-Gantry CranesGantry and semi-gantry cranes are an optimal solution generally preferred in open areas. According to the need; solutions with one, two or no consoles are available. Semi-gantry solutions are suitable for cases where the gaining of space in the building approach and/or the use of existing building columns as carriers is needed. A foot (articulated foot) is positioned as a movable support to prevent horizontal displacements from stresses under load. For the energy supply system, the closed bus-bar system or cable reel drums are preferred. The gantry and semi-gantry solutions are better for usually open field Iron-steel industry, industrial facilities, mining-marble quarries, manufacturing, storage and shipment.
