Potential hazards for employees exist wherever people meet machines. Where a danger zone can be precisely defined, it is possible to protect employees with the GSG Personal Protection System. U-Tech supports companies where system adaptation is concerned.
Operating procedures are presented below, in which the GSG Personal Protection System is implemented. In some cases, adjustments are required. Depending on how the danger zone is depicted, adjustments are made to the antenna, e.g. a circular antenna is used for a tape laying system.
For these companies, the U-Tech protection system GSG202 saves lives. It automatically triggers an emergency shutdown of the machine, when an employee enters the danger zone. In addition, a mobile, radio-controlled emergency stop device is available for these applications.
The Personal Protection System GSG202A, based on RFID, from U-Tech, was certified in 2015 by the IFA, the Institute for Occupational Safety and Health, in accordance with the European standards DIN EN 61496-1 and DIN EN ISO 13849-1 and is thus the only approved safety system of its kind on the market.
The French company Forest-Liné has equipped its tape laying machines used in the manufacture of wings for Boeing 787s (Dreamliners) in Nagoya, Japan, with the U-Tech safety system. A computer-controlled head moves along all three axes when applying tape to wing sections. Engineers are required to visually monitor that the process is carried out correctly while the machine is in motion, meaning there is a risk of engineers being hit by the head of the machine which is ca. one metre in size. A toroidal antenna has been fitted around the adhesive head, generating a magnetic field six metres in diameter. As soon as an engineer equipped with a transponder enters the magnetic field, the head stops automatically.
Employees are required to feed sheets of metal into the opening between the two rollers where there is great danger of fingers and hands being injured. With the introduction of the U-Tech system, all employees were equipped with a wristwatch transponder. As soon as any part of the body enters the defined danger zone, the calender rollers automatically stop.
The antenna has been fitted on the top of the crane so that a protective magnetic field is generated around the moving crane. The crane pushes this protective field forwards as it moves. As soon as this reaches an employee equipped with a transponder, the motion of the crane is halted before the employee is hit by the concrete pipe.
