A lock and dam system for a waterway includes a dam extending across the waterway, a channel having a first entry-exit opening on a first side of the dam and a second entry-exit opening on a second side of the dam. The channel includes a lock. The system further includes a fascia proximate first entry-exit opening in the channel, and a fender system to protect the fascia from impact. The fender system includes a plurality of resilient flexible support element, a first panel supported by a first one of the plurality of support elements in front of the fascia and a second panel supported by a second one of the plurality of support elements in front of the fascia. The first and second panels overlap in a first direction parallel to the fascia and a second direction perpendicular to the fascia. In one exemplary embodiment, the first panel has a first shoulder and the second panel has a first step facing and overlapping the first shoulder. In the exemplary embodiment, the first and second panels have front surfaces which are substantially coplanar.

Fender system

A vehicle impact system includes a road accommodating vehicle traffic in a direction along its center line, a support structure and first and second adjacent energy-absorbing fender elements supported by the support structure and extending adjacent to the road. Each of the first and second adjacent energy-absorbing fender elements includes an elastomeric leg extending non-parallel from the support structure and a contact panel extending from the leg. The contact panel has a contact surface extending substantially parallel to the road center line, a forward end and a rearward end. The forward end of the first adjacent fender element faces the rearward end of the second adjacent fender element such that when the contact surface of the first adjacent fender element is engaged by a vehicle, the leg of the first adjacent fender element resiliently flexes to move the forward end of the first adjacent fender element into engagement with the rearward end of the second adjacent fender element.

Energy absorbing impact system

The lock and dam system for waterway includes a dam extending across the waterway, the channel having a first entry-exit opening on a first side of the dam and a second entry-exit opening on the second side of the dam. The channel includes a lock. The system further includes a fascia approximate first entry-exit opening in the channel, and a fender system to protect the fascia from impact with objects generally moving in a first direction. The system includes a first panel, a second panel, a first support element coupled to one of the first and second panels and coupled to the at least one fascia and a second support element coupled to one of the first and second panels and coupled to the at least one fascia. The first support element extends oblique to said one of the first and second support panels with the second support element extends oblique to said one of the first and second panel. The first and second support elements consecutively extend along at least one of the first and second panels and extend parallel to one another.

A liner for a corrugated debarking drum having a continuously undulating outer wall with an interior surface including an axially extending concave portion includes an elastomeric compressible body having an inner surface adapted to be positioned over the concave portion and an outer surface opposite the inner surface and a support secured to the body and adapted to be bonded to the interior surface without perforating the outer wall.

Rubber lining for corrugated debarking drum

A fender for absorbing the impact between converging bodies includes a supporting surface, a plurality of bosses and an energy absorbing member. The plurality of bosses protrude from the supporting surface at spaced locations. Each boss has an outer perimeter. The energy absorbing member surrounds the outer perimeter of each boss so that each boss absorbs vertical and horizontal shear forces within the energy absorbing member.
