Gantry grab crane

Gantry grab cranes are designed for handling bulk cargo using a special grab gripping device. Depending on the specifics of the lifting operations, a gantry grab crane can be equipped with a rope bucket grab, a removable electromechanical or electrohydraulic grab. Ore grab handlers are widely used in the coal, energy and metallurgical industries, in particular in batch rooms and slag yards of open-hearth shops, as well as at enterprises processing ferrous and non-ferrous scrap metal and at cement plants when working with raw materials. If it is necessary to increase the area of the unloading platform, for example, when unloading ships or vehicles, the span structure of the gantry crane is supplemented with one or two consoles. Grab handlers are equipped with a special grab winch, which, along with the lifting mechanism, has a grab locking mechanism. In this case, it is possible to reeving the grab with opening along or across the bridge span. Since gantry cranes imply work on an open site, a casing house is provided to protect the cargo trolley from precipitation. Being a high structure with a large windward area, the ore grab handler is protected from arbitrary movement by anti-theft grips installed on the running trolleys. In addition, a system for limiting the tilt of the crane is provided on the idle wheels of the running trolleys. Depending on the technological tasks, a mounted or rope grab is installed on the coal handler, which has a single-rope, two-rope, and four-rope design. Rope grabs can open along or across the crane runways and are widely used at sites with a high cargo turnover. At the same time, the use of a mounted drive grab allows transporting piece goods using a hook. When assembling crane units, we take into account the technological specifics of the customer's production, as well as individual requirements reflected in the technical specifications for the crane. In the production of an ore grab handler, we use components from leading manufacturers and trusted suppliers.
