CE Marking In every case the sides of trough shall extend at least two (2) inches beyond the shafting or protuberance. EN ISO 13849-1 29 CFR 1910.219 Mechanical power-transmission apparatus, states that wood guards can be options in woodworking and chemicals industries, and in industries where vapors or gases or other conditions could deteriorate metal guards. The list of possible machinery-related injuries created by moving machine parts is long - amputations, lacerations, crushing injuries, and abrasions, Machine safeguards are essential for protecting worker from these preventable injuries. 0000011098 00000 n A slot opening for jack bar will be permitted. The load type and accumulation are dependent upon the product at hand. This is not stronger as compared to the belt drive. Simply put, conveyor pulleys are responsible for driving the belt. risk reduction Readers with specific questions should refer to the applicable standards or consult with an attorney. The vertical clearance in passageways between the floor and power transmission beams, ceiling, or any other objects, is not less than five feet six inches (5 ft. 6 in.). 1. Screw conveyors commonly used for moving swarf away from the working areas on CNC lathes and used to move all kinds of particulate materials have inherent shear points where the screw passes fixed parts of the conveyor tube. 2002+A1:2010. DEPARTMENT OF LABOR. Conveyor designs range from very small dual-belt conveyors used to move printed circuit boards through electronic board-stuffing machines to pneumatic conveyors moving pelletized plastic from storage silos to injection moulding machines to massive troughed-belt mining conveyors moving hundreds of tons of ore a minute. Thanks for the encouragement! Cutting actions are dangers with bandsaws, circular saws, and boring or drilling machines. High-reliability conveyors, like the mainline and slope conveyors, for underground coal mining operations employ engineered class pulleys, which are attached to large shafts and supported by large diameter pillow-block bearings. Sometimes, hazards are caused by nip points (also called pinch points)points where one or more . Emergency Stop To prevent nips, use fencing between the conveyor belt and the idler pulleys to guard both sides of the conveyor. According to period sales literature from J.B. Hoyt & Co. (New York), "a leather belt will safely and continuously resist a strain of 350 pounds per square inch and a section of 0.4 of a square inch over a turned cast-iron pulley will transmit the equivalent of a horse power at a velocity of 1,000 fps. 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. Bearings. Conveyor pulleys are utilized to move a conveyor belt and the product being carried by the conveyor belt. The basic types of hazardous mechanical motions and actions are: A rotating motion can be dangerous. Item #110753494. Guarding by location locating moving parts away from employees to prevent accidental contact with the hazard point is one option for guarding conveyors. 0000062311 00000 n If more frequent access is required, the guards MUST be interlocked to the power control.

Often, with older machines, they are the only practical solution. Start with writing down the known values. Airtek manufactures conveyor belt dryer machines that adapt to various processes, different types of materials, and humidity ranges. Within the two basic types of conveyors, there are many sub-types, including: Belt Trough Walled Belt Feeder Bucket Chain En Masse Flighted Horizontal reciprocating Vertical reciprocating Pneumatic (these have some special requirements) O-ring Powered and free roller and many more. For emergency stops or shut-offs, you will need these engineering controls: Equip conveyors with interlocking devices that shut them down during an electrical or mechanical overload such as product jams or other stoppages. Couplings. Which of these is required if the worker's body, hands, or clothing may come into contact with moving parts? Degradation of the Fugitive Material. Identifying hazards is the first step toward protecting workers and promoting safety in the workplace. INSTALL fencing around pulleys to isolate hazards. The conveyor belt is a common piece of mechanical handling equipment that moves or transports materials from one location to another. In many circumstances, metal is the best material for guards.
