With transverse motion movement in a straight continuous line moving parts can catch or strike a worker in a pinch point or shear point. Materials carried by overhead conveyors and broken components can fall from the conveyor system. If the belt is of the endless type or laced with rawhide laces, and a belt shifter is not desired, the belt will be considered guarded if the nip point of the belt and pulley is protected by a nip point guard located in front of the cone extending at least to the top of the largest step of the cone, and formed to show the contour of the cone in order to give the nip point of the belt and pulley the maximum protection. These pulleys can be provided with the same shaft as your existing conveyor has. by bacel yahyaoui. The sides of the trough shall come within at least six (6) inches of the underside of table, or if shafting is located near floor within six (6) inches of floor. Brexit 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. For the Textile Industry, because of the presence of excessive deposits of lint, which constitute a serious fire hazard, the sides and face sections only of nip-point belt and pulley guards are required, provided the guard shall extend at least six (6) inches beyond the rim of the pulley on the in-running and off-running sides of the belt and at least two (2) inches away from the rim and face of the pulley in all other directions. Bearings shall be kept in alignment and properly adjusted. User-built guards are sometimes necessary and have some advantages. CONVEYOR EQUIPMENT MANUFACTURERS ASSOCIATION, and AMERICAN NATIONAL STANDARDS INSTITUTE. Identify all the potential hazards in your workplace that require machine safeguarding and ensure they adhere to OSHA regulations. In-running nip points are frequent sites of injuries from machinery.

The OSHA standards on general guarding of machinery and mechanical power transmission apparatus (29 CFR 1910.212 and 1910.219) are very broad and general minimum guarding standards, one of which was predicated on the 1970's version of the ANSI/ASME B15.1 standard, which itself had undergone several revisions (with 2000 as the most recent . 2019. Flywheels located so that any part is seven (7) feet or less above floor or platform shall be guarded in accordance with the requirements of this subparagraph: Cranks and connecting rods. The rotation of the driver pulley increases the tension on one side of the belt, creating a tight side. trailer 0000062082 00000 n Crown Face Type. In the process of doing some work, a pulley is a simple machine that changes the direction and magnitude of the applied force. A: The point of operation is where work is performed on the material, such as cutting, shaping, boring, or forming of stock. The roller is constructed out of stainless steel, 304 SS quality, which gives strong corrosion resistance. 81 298 1. If belt is eight (8) inches or more in width. A conveyor system will always consist of a head pulley and a tail pulley. Standard design features include: They are often used to transport material with minimal effort within a short distance. Determine the angular velocity of the driven pulley using the formula 1: If a machine has an exposed pulley and conveyor but the portion of it that is exposed as well underneath the machine, the employer must post warning signs advising employees not to go near the exposed section.

All mechanical power transmission apparatus located in basements, towers, and rooms used exclusively for power transmission equipment shall be guarded in accordance with this section, except that the requirements for safeguarding belts, pulleys, and shafting need not be complied with when the following requirements are met: The intensity of illumination conforms to the requirements of ANSI A11.1-1965 (R-1970), which is incorporated by reference as specified in 1910.6. Application Guidelines for Vertical Reciprocating Conveyors. Available: https://www.pflow.com/wp-content/uploads/2016/10/vrc-application-guidelines.pdf. Wherever flywheels are above working areas, guards shall be installed having sufficient strength to hold the weight of the flywheel in the event of a shaft or wheel mounting failure. This belt is also made of various types of materials to suit what items will be transported. 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. PROVIDE non-slip surfaces for treads and steps. If a machine has an exposed pulley and conveyor but the portion of it that is exposed is well underneath the machine , the employer must do what Must ensure that all that exposed and accessible sections of the machine are guarded Providing worker training on the safe use of the equipment being operated is the responsibility of who the employer The conveyor belt is a common piece of mechanical handling equipment that moves or transports materials from one location to another. Where guard is exposed to contact with moving equipment additional strength may be necessary. The primary standards sources related to conveyors and used in this article include: [1] Safety Standard for Conveyors and Related Equipment, ASME B20.1. Your email address will not be published. There are three types of pulleys: One has a fixed axle; One has a moveable axle; A compound, which is a mixture of the two; Pulleys can be found everywhere to help make tasks easier. Sprockets for Conveyor Chain Belts. 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. Where guard is exposed to contact with moving equipment, additional strength may be necessary. The guards must not have openings larger than one-half inch (29 CFR 1910.212(a)(5)). Guards for horizontal overhead belts shall run the entire length of the belt and follow the line of the pulley to the ceiling or be carried to the nearest wall, thus enclosing the belt effectively.
