An impact damping devise for a conveyor traction wheel assembly adapted to support an elongated flexible drive member. The traction wheel assembly includes a periphery having a circumferential support surface. The impact damping device comprises an elongated generally elastomeric impact damping having a base adapted to extend along at least a portion of the circumferential support surface. The impact damping member further includes spaced apart sides, a radially outwardly facing surface adapted to define at least a portion of a circumferential surface for supporting the elongated flexible drive member and a hollow portion.

A method for measuring the weight of material carried by a moving conveyor belt at an angle to the horizontal and passing over a belt scale, and a method for calibrating the belt scale under actual field conditions using previously determined calibration curves.

The guide bushing of a blast hole drill is resiliently mounted to dampen lateral vibrations of the drill string. The mounting arrangement comprises four pads symmetrically placed about the bushing and restrained against all but radial movement. Each pad includes a radially inner bearing section that bears against the exterior of the bushing, an outer backing section that is radially movable with respect to the bearing section, and a resilient cushion between the two sections. A four-lobed cam ring surrounds and faces the backing sections and is rotated to simultaneously load all the cushions to a selected degree. In the preferred embodiment, the mounting components are in an enclosed housing that defines guide channels for the pad and that can easily be fitted into the deck of a machine.
