Abstract: A modular friction drive system and method for use with a palletized conveyor. The drive system includes drive assemblies located at opposite sides of both a load end and unload end of the palletized conveyor. Each drive assembly comprises at least one drive unit and at least one take-up unit, which are connected by a drive belt. One or more idler units may reside between the drive unit(s) and take-up unit(s). Each drive assembly is provided with an actuating means for pressing the drive belt tightly against the side walls of associated conveyor pallets. Each of the drive unit, take-up unit, and idler unit is preferably modular in nature and can, therefore, be added to or removed from a drive assembly independently of the other unit(s).

Abstract: An apparatus and method for simultaneously cutting parallel slots in a pavement surface is provided, especially for dowel bar retrofit load transfer restoration at joints. The apparatus includes a movable frame lockable with a brake, plurality of parallel cutting blades rotatably mounted on twin cutting heads on the frame, vertical travel unit for raising and lowering the blades independently or in unison, and horizontal travel units for moving the blades horizontally. One of the twin cutting heads is mounted on each side of the frame, with hydraulic adjusting rams for independently setting the width therebetween. A slurry control system which is mounted on the frame provides the blades with coolant and vacuums up the slurry produced during cutting.
