There are four general types of guards: Safety devices perform several functions. Rotating parts cause hazards such as in-running nip points. In simple two-pulley conveyors with defined running direction it is usually the head pulley that is the driving pulley. Slat Conveyor 28 Figure 31. 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. Overhead conveyors warrant special attention because most of the conveyors drive train is exposed. Where passage is regarded as necessary, there shall be a platform over the lower run guarded on either side by a railing completely filled in with wire mesh or other filler, or by a solid barrier. Let's say that you know the diameter and RPM of the driver pulley (d = 0.4 m and n = 1000 RPM), the diameter of the driven pulley (d = 0.1 m), and the transmitting power (P = 1500 W).You have also measured the distance between the pulley centers to be equal to D = 1 m..

Guards designed and installed by the machine producer are desirable because they conform to the design and function of the machine, and they can be designed to strengthen the machine or to serve some additional functional purpose. Moving machine parts create workplace hazards and potential machinery-related injuries, making machine guards vitally important. Belts which of necessity must be shifted by hand and belts within seven (7) feet of the floor or working platform which are not guarded in accordance with this section shall not be fastened with metal in any case, nor with any other fastening which by construction or wear will constitute an accident hazard. Security check to access the possibility of changing to an employee who inadvertently. Conveyor-related injuries typically involve a workers hands or fingers becoming caught in nip points or shear points on conveyors and may occur in these situations: Other conveyor-related hazards include improperly guarded sprockets and chain drives. Section 12.23 states "A belt conveyor must have accessible nip points of spools and pulleysguarded to prevent contact by a worker." And, section 12.22 states "Unless otherwise permitted by this Regulation, a conveyor must meet the requirements of ANSI Standard ANSI/ASME B20.1-1993,Safety Standards for Conveyors and Related Equipment". Conveyor pulley standard Background The traditional conveyor pulley typically has a through shaft on bearings supporting a lagged drum.
