Technical specifications


A) Operative part:

It is composed of a mobile frame, including:

- Chemical oil cleaning station,

- Rinsing station,

- Acid dipping station,

- Acid zinc plating station,

- Horizontal translation motor,

- Vertical translation motor,

- Jib crane,

- Retention tank,

- Filtering block ,

- Electrical cabinet,

- Transparent safety guard of the working area,

- Ventilation hood

  • The handling of the jib cranes in the 2 axes Y and Z (horizontal and vertical) is made with a speed of displacement of about 0,2 m/s.

  • Temperature control of the chemical oil cleaning bath by waves-train and static relays,

  • The feeding of the electrolytic zinc plating bath is made by a current generator of 0-10 A with controlled direct current.

  • Supply of the current generator from the single phase network

  • Display of tension and current.


B) Operative part:

  • An electrical cabinet integrating:

  • A compact PLC with analogical inputs/outputs and TOR, PID regulation, 2 interfaces of communication.

  • A interactive exploitation dialog terminal with 2 display lines. 20 characters. communication with the PLC on the serial line, UNI-TELWAY protocol, 12 keys function keyboard,

  • 10 service keys and 12 numerical keys.

  • Programming made on several application pages and alarms pages.

The power supply and people protection devices : differential circuit-breaker, contactors. fuses, transformer.

Current generator for the electrolytic zinc plating bath.



The PLC assures the following functions:

- Management of 5 positions on the Y axis in order to ensure the operations of chemical oil cleaning, rinsing, acid dipping, rinsing and zinc coating.

- Management of 2 positions on axis (high and low).

- Temperature control of the chemical oil cleaning bath.

- Manual run.



- Aspiration of steams above all the tanks,

- No waste to the sewage, the wasted baths will be reconditioned in delivery cans of and sent to approved centres for the treatment,

- The sounding environment is distinctly lower to 70db.

- People security by the transparent surrounding wall locked wit a key.

- Auto-control of the door sensor by a security box.
