Abstract
Abstract In a compactor in which a ram is mounted for reciprocating movement to compact material deposited in the compactor, supporting structure is provided for resisting forces placed upon the base of the compactor during compacting strokes of the ram. The supporting structure includes a flat base member having a supporting structural channel attached thereto by welding and a sheet member which extends over the channel and is attached to the base member on opposite sides of the channel. This construction places the sheet member under tension in resisting the compacting forces exerted by the ram and prevents buckling of the base member. Preferably the sheet member and the channel are assembled first and this unit is then attached to the base member by, for example, spot welding the upper flange of the channel and edges of the sheet member to the base member. To permit the upper flange of the channel to be attached to the base member in this manner, the sheet member covering the channel is provided with openings through which a welding electrode may be inserted to attach the channel to the base member.
