The tunnel stacker is also called the tunnel stacker crane. The stacker is the most important handling equipment in the automated warehouse. It is a special crane developed with the emergence of automated warehouse, which is specially used in the elevated warehouse.Roadway stacker is generally composed of rack, running mechanism, lifting mechanism, cab, fork telescopic mechanism, electrical control equipment, etc.
1. Tunnel type single column stacker
The frame of stacker with single column structure is composed of a column and a lower beam.Most of the columns are welded with large H-beam, and the guide rail is attached to the column.The whole machine is light in weight and consumes less materials, so the manufacturing cost is relatively low, but the rigidity is slightly poor.The parameters of the device are as follows.
Main performance: warehouse height 6 ~ 24m, maximum 40m;
Running speed: standard type 80m / min, high speed type 200m / min;
Lifting height: standard type Hmax = 20m / min, high speed type Hmax = 50M / min;
Fork expansion speed: Vmax = 12m / min (standard), 50M / min (high speed).
2. Double column tunnel stacker
The frame consists of two columns, an upper crossbeam and a lower crossbeam to form a rectangular frame.There are square tube and round tube in the form of column. The square tube is also used as lifting guide rail, and the round tube needs additional lifting guide rail.
