Abrégé

An asymmetrical gusseted clamp assembly configured to be coupled to a lift truck and comprising a frame, two clamp jaws and two actuators. The clamp jaws each have gussets of different size to allow the two actuators to be separated vertically by a central gap, which is defined on the sides by two frame vertical beams. The central gap is of significant width so that the operator of the lift truck has a useable widow through which to view. As the configuration of the asymmetrical gusseted clamp assembly changes from open to closed, at no time is a majority of the view through the central gap obscured by the clamp jaws.
