Double Girder Electric Overhead Travelling Crane Overhead Bridge Crane 5t-500ton

Overhead Bridge Crane 5ton ~ 500tonProduct DescriptionTraditional Double Girder Overhead Crane with Wire Rope HoistThe electric hoist bridge crane is composed of a box-shaped bridge frame, a cart operating mechanism, a trolley, and electrical equipment. The fixed electric hoist is installed on the trolley frame as a lifting mechanism. The trolley operation adopts LD transmission, and the cart operation is divided into There are two types of LD drive and QD drive. The structure is simple and lightweight, with the characteristics of small overall height and light weight. It is suitable for workplaces such as factories and mines, workshops and warehouses within the range of small and medium lifting weights. There are three operation modes: ground handle, wireless remote control and driver's cab. There are two types of cabs: open and closed.Slewing Overhead Crane It is used to transport ferrous metals such as long slabs and bars. Rotation is realized in two ways. One is the hanging beam rotation, that is, the hanging beam has a double-layer structure. The upper hanging beam is wound with steel ropes through a pulley block, and the lower hanging beam is equipped with multiple electromagnetic chucks or clamps, which can rotate with the drive mechanism to a certain angle. . Another form is trolley rotation, that is, the trolley has a double-layer structure, the upper trolley is equipped with a lifting mechanism, the lower trolley is a running trolley, and the ring track is laid on it, and the upper trolley can rotate along the ring track.Electromagnetic Overhead Crane This crane uses hanging beams to lift long billets, plates, bars, coils and other items, and is equipped with electromagnetic chucks or clamps or special group hooks for hoisting. It is mainly composed of box bridges, cranes, cart operating mechanisms, and drivers. It is composed of room and electrical control system, equipped with power outage magnetism protection system. The hoisting mechanism mostly adopts single motor, double reducer, double drum arrangement, in the form of double lifting points. The hanging beams are arranged in two ways: perpendicular to the main beam or parallel to the main beam. The other forms are the same as QD cranes.Double Hook Overhead Bridge Crane The difference between a double trolley bridge crane and a hook bridge crane is that two trolleys are set on the main beam. The double trolleys can be lifted or run independently; when long items need to be lifted, use the switch on the console , Realize synchronous lifting and synchronous operation.Electromagnetic Overhead Bridge Crane The basic structure of the electromagnetic bridge crane is the same as that of the hook bridge crane. The difference is that a DC lifting electromagnetic chuck is hung on the hook, which is used to lift the magnetically conductive ferrous metal and its products. The AC power supply is converted into a DC power supply through a thyristor DC box installed in the driver's cab, and then the DC power supply cable is sent to the electromagnetic chuck through a special cable reel set on the trolley. Grab Overhead Bridge Crane The grab bridge crane is mainly composed of a box bridge, a grab trolley, a cart operating mechanism, a driver's cab and an electrical control system. The fetching device is a grab bucket. A lifting mechanism and an opening and closing mechanism are arranged on the grab trolley, and the grab is respectively wound on the lifting and opening and closing reels with four steel wire ropes. The opening and closing mechanism drives the grab bucket to close and grabs the material. When the bucket mouth is closed, the lifting mechanism is activated immediately, so that the four steel wire ropes are evenly loaded for lifting work. When unloading, only the opening and closing mechanism is activated, and the hopper opens immediately, tilting the material. Except for the different lifting mechanism, the rest of the structure of the crane is basically the same as that of the hook bridge crane. Traditional Double Girder Overhead Crane Hook bridge cranes are currently widely used hoisting machinery, which are mainly composed of box bridges, crane trolleys, cart operating mechanisms and electrical control systems. The retrieval device is a hook. A track is laid on the main beam for the crane trolley to move laterally along the direction of the main beam. The main girder is welded to the box-shaped end girder, and there are joints arranged in the middle of the end girder, which are connected by bolts or pins, for the bridge frame to be disassembled and transported. There are three operation modes: ground handle, wireless remote control and driver's cab.Detailed Photos Product Parameters   Features:1) Reasonable structure2) Favorable performance3) Smooth starting and stopping4) Safe and reliable traveling5) Low noise, commodious cabin and good view6) Convenient maintenance, excellent exchangeability for parts and components7) Saves electricity   No
