BUTT GmbH – yard ramps & industrial doors

Type FBTS tandem spring-loaded
dock leveller made from aluminium

The type Tandem spring-loaded dock leveller is used to bridge large height differences (vehicle is much higher than the existing ramp height). It consists of a dock leveller with spring compensation and a dock leveller split in the centre without spring compensation.

Depending on the application, it is used by folding part one of the dock leveller onto the ramp and part two onto the vehicle. In its rest position, the Tandem dock leveller is automatically secured.
