Common protective devices used in processing workshops include protective covers, protective baffles, protective railings and protective nets. Protective devices must be installed on mechanical equipment with exposed gears close to the ground, couplings, shafts, pulleys, flywheels, grinding wheels and drive belts of chain saws.
Presses, rollers, calenders, electric planers, shears and other spinning parts of presses must have safety devices. Protective covers are used to isolate exposed rotating parts such as pulleys, gears, sprockets, shafts, etc. Protective baffles and protective nets are available in fixed and mobile forms, which play a role in isolating and shielding metal chips from splashing.
Guardrails are used to prevent people from falling or to demarcate safe areas. Generally speaking, the main forms of protective devices are fixed protective devices, interlocking protective devices and automatic protective devices.
