Grab magnet gantry crane
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.
Mechanism configuration of magnet grab gantry cranes with 1 trolley can be with location of actuating devices both along the crane span and across it. It is convenient during handling of prepared scrap in large special transport vehicles: transfer cars or scrap transporting vehicles.
According to its structure magnet grab gantry crane is of double cantilever type with a double bridge of sheet structure. The crane is equipped with supporting trolleys and a fixed control cabin which is fastened from external side of rigid support. Control of all mechanisms is carried out from the panel located in control cabin.
Metal structure of the crane is its base on which the rest of crane parts are mounted and it is intended for perception and transmission of all loads to a crane track which occur during cargo hoisting and handling.
Grab trolley is intended for location of lifting mechanism, grab blocking mechanism and travelling mechanism (which ensures its travelling along the crane bridge) and electric equipment. Depending on particulars of cargo lifting procedures the magnet grab gantry crane can be equipped with a rope ladle grab, a removable electro-mechanic or electro-hydraulic grab. Application of the hinged driven grab allows to transport piece cargoes by means of a hook.
Magnet trolley is intended for location of a lifting mechanism, mechanism of electric cable connection to the magnet, travelling mechanism (which ensures its travelling along the crane bridge) and electric equipment. A plug connector for connection of the cable (which feeds a cargo lifting electric magnet) is fastened to a hook suspension. The hook itself is equipped with a safety lock. The magnet grab crane can work with piece cargoes in a hook mode when electromagnet is removed.
To protect cargo from falling off the magnet a wiring scheme of the magnet grab crane is made in such a way that (while actuating appliance and security devices) magnetic strength is not removed from the magnet.
Crane travelling mechanism consists of 4 pcs. of 2-wheel driven trolleys , 2 anti-creepage devices with operation from the cabin.
While making crane configuration we take into consideration Customer’s production process particulars and individual requirements indicated in crane technical specification.
While manufacturing magnet grab gantry cranes we use components of leading manufacturers and reliable suppliers.
