What is a Overhead Stacker Crane

overhead stacking crane

On the basis of bridge crane, combined with the characteristics of forklift truck developed. On the rigid column that is suspended from the lifting trolley, there is a lifting fork. The column can rotate around the vertical center line, so the width of the roadway between the shelves is smaller than that needed for the operation of the forklift. The crane is supported on both sides of the elevated track and can carry long objects in addition to the ordinary unit cargo. When the weight and span are small, it can also be run on the track hanging below the roof truss. At this time, its hoisting trolley can transit to another suspended crane on the adjacent span. The column may be a single or multi section telescopic type. The single column structure is simple and light, but it can not cross the cargo stack and other obstacles. It is mainly applicable to the warehouse with shelves. Multi section telescopic generally have 2 to 4 day post, can cross the goods, no shelf warehouse and therefore can be used for the goods directly into the stack stacking unit. The crane can be controlled on the ground or in the driver's room with the fork. Rated lifting capacity is generally 0.5 to 5 tons, and some can reach 20 tons, mainly used in height below 12 meters, span within 20 meters of the warehouse.
