QY overhead isolation crane is basically the same as bridge crane with a hook in terms of structural style. To avoid the charged equipment which may conduct electricity to the crane by hoisted articles from endangering the driver’s life, insulation equipment set on the hook group, crab frame, crab wheel (or under the crab rails). The insulation material is usually epoxy phenol aldehyde glass cloth laminated board. The crane is applicable to aluminum and magnesium smelting factories.
It is mainly used in the environment of high-temperature molten salt, high current, strong magnetic field, dust and hydrogen fluoride atmosphere in the electrolysis workshop.
The insulated feeding crane is composed of a bridge frame, cart operating mechanism, tool trolley, aluminum tapping trolley, feeding trolley, electrical control system, air compressor, and gas circuit control system, hydraulic station and oil circuit control system.
The bridge frame adopts a three-beam and three-trolley structure. The main girder is covered with a track for the trolley to run. The off-track arrangement. The lifting trolley and the aluminum tapping trolley run on the same track, and the feeding trolley runs on the other track.
The operating mechanism of the cart adopts an 8-wheel 2-drive, equipped with a shaft-mounted three-in-one reducer, and is equipped with horizontal guide wheels,
The driver’s cab and electrical room are equipped with industrial heating and cooling air-conditioning.
