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.

Hook gantry cranes for general purposes are intended for implementation of lifting, cargo handling and storage  of piece cargoes.  Hook gantry cranes for general purposes work in open areas of almost all types of industrial plants, railway stations, warehouses and other industrial facilities.

Grab gantry cranes are intended for bulk cargo handling by means of a special grab gripping device. Depending on particulars of cargo hoisting procedures the grab gantry crane can be equipped with a rope ladle grab, a removable electro-mechanical or an  electric hydraulic grab.

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.

Assembly gantry cranes are used for installation of prefabricated  industrial and civil buildings, for maintenance of erecting sites (of site joints) and equipment of petrochemical plants and enterprises of power industry including hydraulic electric stations and also during sectional installation and assembly work  in shipyards and ship repair facilities.

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.

Log handling gantry cranes are designed for the high-capacity handling of long materials in a timber yard. 
The use of a rail-mounted gantry crane compared to wheel-mounted machinery significantly increases the line capacity, reduces handling costs and shortens the payback period of the investment.

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.
