Our grate bar with lateral locking is patented!

The common roller grate bar has been remanufactured and improved by WVT Breiding. The grate bars are locked to each other. Even if one or even several grate bars are broken, the roller grate will continue to work due to the fact that the grate bars will not fall off the cylindrical rollers!
