Safety is a number one priority when it comes to CoastOne Electric Press Brakes both before and after your purchase.

This blog post focuses on CoastOne electric press brake safety features, operator tips and frequently asked questions involving the maintenance and operation of your press brake. 

What safety features does the CoastOne Press Brake system have to prevent operator injuries?

The CoastOne system has the following protections against operator injuries:

  • A light curtain, laser actuated Lazersafe Laser Active Optic Protective Device (AOPD), hold-to-run control, and scanner system to stop the beam from closing and keep it stopped when an object is detected in the closing space. When a safety device is disabled or access is prevented only by a hold-to-run control, the press brake beams’ closing speed is limited to <=10 mm/s.
    This optical protection system includes a laser transmitter and receiver that continuously protects the area around the punch tip, so the operator can hold the workpiece while the brake beams close, giving the operator increased productivity.
    Unlike traditional light curtains, this system reduces operator fatigue by reducing the need to move in and out of the operating area.
  • A safety foot pedal for hold-to-run control with 3 positions, where the 1st and the 3rd position stop the closing of the press, and the 2nd position allows the closing.
  • Programmable reduced bending speed for protection against injury caused by the deflection of a protruding workpiece.
  • Side guards to prevent lateral reach from the sides of the machine into the danger zone.
  • An interlocked back guard to prevent access from the rear of the machine to the danger zone.
  • An emergency stop for all actuators to stop and to be isolated from the power source.

What warning signs are shown to the operator?

The following signs are posted at strategic points, warning the operator of dangers:

Warning sign in electric cabinet door for the danger of electric shock
Warning sign in front of the machine for the danger caused by deflection of protruding workpieces
Warning sign in front of the machine for the danger of getting crushed between bending tools
Warning sign in front of the machine for the danger of getting crushed between a work-piece and parts of machine

What ways are there to prevent accidents during normal operation?

When using this machine, operators should be careful and exact, because this machine is classified as a dangerous construction machine. The manufacturer does not take responsibility for any  damage to the machine or accidents that are caused by machine abuses. The warnings below should be taken into consideration when using the machine.

  • Watch out for the moving tools that fingers can be caught in. If safety devices like AOPD are disabled, or the machine is designed to close only at the safety speed, the closing speed is limited to 10mm/s, and closing movement will always be stopped by releasing the pedal or pressing the pedal over the force limit to position 3. Make sure that releasing of any trapped person, described in the “Release of trapped person” section in the User Manual, is clear.
  • Watch out for any deflection of protruding workpieces. In the case of a long, protruding workpiece, adjust the bending speed to 1 mm/s and increase it little by little until the bending process feels comfortable and the end of the long workpiece is not moving dangerously fast.
  • Be careful when bending box-shaped parts, as fingers can be crushed between the existing, upwards protruding side of the part and the frame of the machine. Pay attention to how you hold the part; never hold the part from the end where the upwards protruding side is.
  • Back gauge manual adjustments must be done through the back door. Never place hands between tools; this must be a basic rule even if power is turned off.
  • Only a professional electrician is allowed to open the control cabinet door.
  • After a tool change, pay attention to the programmed tool values and AOPD Incorrectly programmed tool values may lead to breaking the tools. If the AOPD is adjusted in an incorrect way, the adjustment might prevent the machine from operating correctly. See the User Manual for instructions on programming tool info and adjusting the AOPD.
  • Machine toppling during transportation can cause serious injuries and break the See the “Transportation” section of the User Manual for instructions on transporting the machine safely.
