Abstract
A high production, double lift box baler having a pair of lift box assemblies which rotate between a charging position and a compression position. Each lift box assembly includes a lift box and a displaceable lower platen which has a latched position in which the lower platen forms a floor of the lift box. Each lower platen also has an unlatched position in which the lower platen is independently displaced to rest against a bottom sill during a compression cycle to withstand the compression forces. The lower platens are independently displaceable, so that while one platen is displaced against the bottom sill for compression, the other sill is latched and is utilized as a floor for tramping the fibers during a filling cycle. A latch assembly is provided for unlatching the lower platen at the compression position during a compression cycle, and for latching the lower platen integrally to the lift box for rotation and tramping. A unique bottom sill extends only across a part of a width of the baler and provides open access to the actuators and rotational drive of the baler for servicing.
