What is the structure of the middle groove?

The middle groove is welded by the groove collar and the middle plate. In order to reduce the resistance of the return of scraper chain, or to prevent the tank from sinking when the bottom plate is used under soft conditions, the bottom plate is welded under the groove edge to form a back sealing groove. The form of the middle slot has been standardized. At present, there are three forms: single chain, double chain and medium double chain. The length of the middle groove is determined according to the width of the support, most of which are 1.5m and 1.75m.


There are three types of channel side steel: D-shaped, E-shaped and M-shaped. Compared with the M shape, the E shape not only increases the stiffness due to the reduction of the width of the middle plate, but also enhances the weld strength of the middle plate and the channel side steel, which is convenient for welding and the chain does not grind the weld.
