Overhead Crane Finished Installation
(The above picture is for reference to crane model only)
The double girder grab overhead crane fetching device is a grab bucket that can grab bulk materials. The double girder grab bridge crane has an opening and closing mechanism and a hoisting mechanism, and the grab is suspended on the opening and closing mechanism and the hoisting mechanism with four wire ropes respectively. The opening and closing mechanism drives the grab bucket to close and grab the material. When the bucket mouth is closed, the hoisting mechanism is started immediately, so that the four steel wire ropes are evenly loaded for hoisting work. When unloading, only the opening and closing mechanism is activated, and the bucket mouth is opened immediately to tilt the material. Except for the different lifting mechanism, the rest of the structure of the grab bridge crane is basically the same as that of the hook bridge crane.
Application of double girder grab bridge crane:
1. Double-girder grab bridge cranes are widely used in power plants, freight yards, workshops, docks, coal stations, etc. for the loading and unloading of bulk materials.
2. Double-girder grab cranes are strictly prohibited to be used in flammable and explosive environments. If there are special needs for use, non-standard design can be customized.
3. All mechanisms of the grab bridge crane are operated in the cab, and the directions for entering the platform door of the cab are: end entry, side entry and top entry.
4. The grapple crane is equipped with a grab bucket, and the style and model specification of the grab bucket can be selected according to the needs of use.
5. The opening direction of the grab is parallel and vertical. The grabbing device is a four-rope grab with double drums, which is simple in structure and reliable in operation. The grab can be opened and closed at any height. When the grabbing material particles are less than 100mm, the effect is good and the production efficiency is high. When the grabbed particles are 200mm large, a toothed grab is required.
