U-Tech SPECIAL SYSTEMS
Customer-specific solutions with U-Tech

U-Tech supports companies in all branches of industry in adapting and developing the U-Tech system to local conditions, whether in sawmills, concrete plants or even the humid environments of the malting industry.

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 personal protection system. U-Tech supports companies where system adaptation is concerned.

Operating procedures are presented below, in which the personal protection system is implemented. In some cases, customisation is 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.

The U-Tech personal protection system saves lives at these companies. 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.

Emergency-stopp system

Complex industrial plants with up to 15 conveyor belts are very confusing and difficult to monitor. The personal protection system U-Tech can easily be upgraded to a remote shutdown system. Each employee is equipped with a PSM nano or PSM Pro, which he wears on his wrist. If he recognizes a problem within his sight, be it a danger for himself or a colleague or a technical problem, he can bring the entire system into the emergency stop state by pressing an alarm button on his wristband transponder.

Tape-Laying-System

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.

Calender-Rollers

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.

Computer-Controlled Crane

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.

Bale slitting device

In the non-woven industry, old fabrics are cut up with the aid of bale slitting machines into recyclable fabric material and are pressed into bales for further processing. This is where the U-Tech Personal Protection System can also be employed.
