Common Types of Safety Guards Found on Hydraulic Press Accessories:
1.Point of Operation Guards: These guards are placed at the point where the material is being processed, such as the area where the die sets come together. They prevent operators from reaching into the danger zone while the press is in operation. Point of operation guards may include barriers, shields, or light curtains that detect the presence of objects or people and stop the press if someone enters the danger zone.
2.Barrier Guards: Barrier guards are physical barriers or enclosures that surround the entire press or specific hazardous areas. They prevent access to moving parts, such as the ram, flywheel, or other machinery components, during operation. Barrier guards are typically made of durable materials like steel or polycarbonate and are securely mounted to the press frame.
3.Interlocking Guards: Interlocking guards are equipped with safety switches or sensors that prevent the press from operating unless the guard is securely in place. These guards are designed to ensure that operators cannot bypass or disable them while the press is running. Interlocking guards may use mechanical, electrical, or pneumatic systems to control access to hazardous areas.
4.Two-Hand Controls: Two-hand controls require operators to use both hands simultaneously to initiate the press cycle. This design prevents accidental activation of the press and ensures that operators keep their hands clear of the danger zone during operation. Two-hand controls are often integrated with other safety features like interlocking guards for added protection.
5.Emergency Stop Devices: Emergency stop buttons or switches are installed at various locations around the press, allowing operators to quickly halt the machine in case of an emergency. These devices provide a means for immediate shutdown and are easily accessible to operators in case of danger.
6. Safety Labels and Signs: Safety labels, signs, and markings are placed on the press to provide warnings, instructions, and information about potential hazards. They help educate operators and other personnel about safe operating procedures and remind them to use caution when working with the equipment.
7. Safety guards on hydraulic presses should be designed, installed, and maintained according to relevant safety standards and regulations. Regular inspections, training programs, and risk assessments are essential for ensuring the effectiveness of safety guards and preventing accidents in the workplace.
