if a machine has an exposed pulley and conveyor

CE Mark . European Committee for Standardization (CEN). Moving machine parts create workplace hazards and potential machinery-related injuries, making machine guards vitally important. Workers have been injured or They may stop a machine if any part of a body is inadvertently placed in the danger area. With transverse motion movement in a straight continuous line moving parts can catch or strike a worker in a pinch point or shear point. In every case the sides of trough shall extend at least two (2) inches beyond the shafting or protuberance. It takes at least two to travel and are categorized as drive or head, return or tail, bend tensioning, snub tensioning or take-up pulleys. PXT30 Bushing Series. Consenting to these technologies will allow us to process data such as browsing behaviour or unique IDs on this site. Allow safe lubrication: If possible, the machine should be able to be lubricated without removing the safeguard. The surface finish of the belt itself and the characteristics of the belt material, combined with the motion of the belt, create the abrasion hazard. The primary standards sources related to conveyors and used in this article include: [1] Safety Standard for Conveyors and Related Equipment, ASME B20.1. Tail pulley: the terminal pulley at the loading end of the conveyor. We precisely cut the tube by using the flame cutting machine, and weld the inner pulley disc by using the professional pulley welding machine, and weld the pulley sleeve & disc by using the positioner. We engineer conveyor pulleys in a wide range of diameters and lengths to suit all applications. 0000008142 00000 n OSHA Machine Guarding E-Tool. 2018. conveyor: a horizontal, inclined, or vertical device for moving or transporting bulk material, packages, or objects in a path predetermined by the design of the device and having points of loading and discharge, fixed or selective. 29 CFR 1910.212 (a) (1) states that one or more methods of machine guarding must be used to protect operators and other employees from hazards, including those created by point of operation, in-running nip points, rotating parts, flying chips and sparks. safety label Pulleys with grooved rims are called sheaves. This subparagraph does not apply to keys or setscrews within gear or sprocket casings or other enclosures, nor to keys, setscrews, or oilcups in hubs of pulleys less than twenty (20) inches in diameter where they are within the plane of the rim of the pulley. Bolts, nuts, and setscrews will, however, be permitted where they are covered with safety sleeves or where they are used parallel with the shafting and are countersunk or else do not extend beyond the flange of the coupling. VIA PRVENTION. Often, with older machines, they are the only practical solution. For flywheels with smooth rims five (5) feet or less in diameter, where the preceding methods cannot be applied, the following may be used: A disk attached to the flywheel in such manner as to cover the spokes of the wheel on the exposed side and present a smooth surface and edge, at the same time providing means for periodic inspection.
