Gantry and semi-gantry cranes

Tehnoros” Group of companies designs and manufactures gantry and semi-gantry cranes for handling of piece & bulk cargoes in open warehouses of industrial plants, cranes for equipment installation, assembly facilities and sectional installation in ship-building as well as gantry container cranes for warehouse terminals, ports and railway stations.

Special gantry cranes are equipped with special cargo handling devices – grabs, magnets, spreaders or traverses of different shape for implementation of specific cargo handling procedures.

Gantry cranes can be equipped with one or two trolleys, with longitudinal  or cross location of traverses on  a flexible or rigid suspension. It is possible to manufacture gantry cranes with non-standard parameters.

While making configuration of gantry crane units we take into consideration manufacturing process particulars of Customer’s production facilities as well as individual requirements indicated in Specification of the crane. While manufacturing special gantry cranes we use components of leading manufacturers and reliable suppliers.

Magnet gantry cranes are intended for implementation of main procedures during handling and storage on open platforms of metallurgical plants, large scrap metal companies as well as scrap processing plants. By means of  a permanent or an electric magnet which is suspended on a hook or on a traverse, the gantry crane can catch and handle plates and sections,  blank parts, billets, metal scrap, chip scrap and other ferrous-magnet materials. Along with that magnet cranes can work with piece cargoes in a hook mode when the electric magnet is removed.

Grab magnet gantry cranes, as a rule, are manufactured with two trolleys and are widely used for unloading, loading, assortment and storage  of ferrous metal scrap in charge preparation plants and in slag yards of open-hearth plants as well as in ferrous / non-ferrous scrap processing plants.

Application of magnet grab cranes allows alternate loading of moulds, production process packages, railway transport or trucks by means of magnets and /or a grab as well as handling of piece cargoes.

Gantry cranes with 2 trolleys  are as a rule of the same loading capacity and they are equipped with hooks as cargo gripping devices for lifting, handling of long and large cargoes while two trolleys work simultaneously. In this case  loading capacity of the  gantry crane  is characterized by summarized (total) loading capacity of two trolleys.

The gantry cranes with a traverse are intended for long cargoes operations, as well as for rails, pipes and beams transfer. Besides, using such cranes, it is possible to transfer oversized cargoes and cargoes of irregular shape.

When it is necessary to stack long cargoes with a turn, the traverses can be equipped with expending or rotating mechanisms.

The cranes with a traverse are widely applied in metallurgical industry, ship building industry, on large scrap metal plants, at reinforced concrete manufactures, in timber industry and other industries.

The ore gantries are equipped with a grab and they are intended for bulk cargoes handling, including sintered iron ore, coke, iron-ore pellets and coal. The ore gantries have the increased lifting capacity, bigger hoisting height (in some cases up to 50 meters), sufficiently increased trolley speed and span length up to 120 meters. Depending on handling operations specifics, the ore gantry can be equipped with a rope bucket grab, a removable electromechanical (electro-hydraulic) grab.
