Study Notes
Conveyor Safety Training
- Personnel must receive thorough conveyor safety training and review the manual before operating, maintaining, or being near the conveyor.
- Operators must be familiar with the structure and operation of the conveyor, points of danger, safe working and moving near the conveyor, and emergency stop functions.
Points of Danger
- Drive end
- Tensioning end
- Nip points of pulleys
- Nip points of idlers
- Loading and discharging locations
- Material flow
- Electric equipment and cables
- Conveyor folding and raising mechanisms
Safety Precautions
- The conveyor should only be used for its intended purpose and in the conditions agreed upon by the user and manufacturer.
- Unauthorized persons are not allowed to be near the conveyor.
- The conveyor belt should not be used as an access or maintenance walkway.
- No changes are allowed to be made on the conveyor without the manufacturer's written consent.
- All those moving near the conveyor must use marked walkways, service platforms, stairs, and ladders.
- The conveyor area must have sufficient lighting.
- No safety devices are allowed to be removed.
Automation System Safety Instructions
- Equipment safety considerations:
- Take care not to hit the display with sharp or hard objects.
- Use the display with bare fingers only.
- The automation system must be serviced by authorized maintenance personnel only.
- The warranty becomes void if the equipment is opened by an unauthorized person.
- Welding the unit:
- Always take care to protect the control system when welding the unit.
- Stop the engine, disconnect the grounding cable from the batteries, and disconnect the engine wire harness sockets from the engine control board.
- Fasten the grounding cable of the welding device as close to the part to be welded as possible.
- Make sure that no welding current passes through any bearings or electrical equipment.
Emergency Stop Buttons
- The emergency stop buttons connected to the process control system stop the motor and the crushing process after the safety function has been triggered.
- The trip wire switches in the conveyors only stop the conveyor in question.
- To reset an emergency stop button, pull the red button to its outer position.
- Before restarting the machine, ensure the area is clear around the unit and that no one will be endangered by your action.
- CAUTION! The operation of the emergency stop buttons must be checked weekly.
Warning Signs
- The warning signs attached to the equipment must always be kept readable and clean.
- Damaged or loose signs must be replaced at once.
- If a component of the machine with an attached warning sign is replaced, always make sure that the required warning signs are included with the new component.
