[6] Occupational Safety and Health Administration. 32 in Face Width. Abrasion hazards are created by the moving surfaces of the head and tail pulleys and the idler rollers along the length of the conveyor. 0000062082 00000 n 0000084626 00000 n The Ferrite roller has a typical strength of 1500 - 2000 gauss; the high-intensity Rare Earth magnetic roller, the most powerful available of this type, has a strength of 3500 gauss, giving it the capability of removing smaller particles. In powerplants only the lower run of the belt need be guarded. Any material that falls between the conveyor belt and the pulley poses a potential danger if the material fails, Breaking down into small enough particles to fit between the components. In many circumstances, metal is the best material for guards. Bearings. Iron Ore Port Facility High Tension Bend Pulley - Elastotec Polyurethane Lagging In November 2017 a major iron ore port facility in the Pilbara decided to replace the ceramic lagging on a high tension bend pulley - the ceramic lagging had suffered physical damage on one edge that had exposed the pulley shell. Degradation of the Fugitive Material. Ensure that all conveyor openings, such as wall and floor openings, chutes and hoppers, have guards when the conveyor is not in use. Belt perches. Material trapped in this location can allow the belt to slip against the pulley, causing the non-carrying underside of the . Screw conveyor machine. Cranks and connecting rods, when exposed to contact, shall be guarded in accordance with paragraphs (m) and (n) of this section, or by a guardrail as described in paragraph (o)(5) of this section. Conveyor systems are everywhere, from the baggage handling systems in airports to people movers in airports and malls to package handling, mining, and general industrial applications. Where belt shifters are not directly located over a machine or bench, the handles shall be cut off six feet six inches (6 ft. 6 in.) DEPARTMENT OF LABOR. If the frame of the belt shifter does not adequately guard the nip point of the belt and pulley, the nip point shall be further protected by means of a vertical guard placed in front of the pulley and extending at least to the top of the largest step of the cone. See for yourself one of our conveyor pulleys and get up close with the components in 3D. Create no interference: Any safeguard that impedes a worker from performing a job quickly and comfortably might be bypassed or disregarded. The standard unit comes in five sizes, with pulley diameters from 4 to 10 in. Figure 27. Roll-Forming Machine 33 Figure 34. The in-running nips between the belts and head pulleys require fencing that encloses dangerous parts with rigid guards that prevent reach into the conveyor from any angle, including underneath.

If made of pipe, the post shall be one and one-fourth (114) inches inside diameter, or larger. Create no new hazards: A safeguard defeats its own purpose if it creates a hazard such as a shear point, a jagged edge or an unfinished surface. INSTALL fencing around pulleys to isolate hazards. They may stop a machine if any part of a body is inadvertently placed in the danger area. Damage to the pulleys surface can increase the abrasiveness of these surfaces, while some conveyor systems use knurled surfaces to increase friction between the head pulley and the belt. 0000009708 00000 n 2006/42/EC The air-cooled motorized pulley for conveyor belt has 2 types: forced air cooling & natural air cooling. 33 0 obj<> endobj 0000001416 00000 n Tail pulley: the terminal pulley at the loading end of the conveyor.
