Abstract
The trailing, load supporting component of a product conveyor is connected to a powered, leading component by a shock absorbing tow bar that employs relatively movable friction elements in a sandwich configuration to absorb the shock by sliding engagement at internal wear surfaces. A brake tongue slides between opposed brake pads of the sandwich which are placed under pressure against the tongue. A two-piece, telescoping tubular housing shields the brake assembly from contaminants and enhances the structural integrity of the unit.
