The FBS drawbridge leveller covers most loading applications and can be used for height differences of up to 250 mm with a load capacity of 6000 kgs. The five bar tread plate surface gives a high quality antislip surface. Finish is available in either galvanised or paint. Both options protect against corrosion. They are available in static or in sliding version. The sliding model runs in a open base guide rail which prevents the collection of dirt and debris, ensuring  smooth, easy sideways movement.  Every leveller is fitted with underside springing to balance the weight of the platform.
