Explosion proof electrical stacker trucks for AkzoNobel
On several production sites, AkzoNobel uses Sichelschmidt explosion proof electrical stacker trucks with a customized built-in RAVAS scale.
For ATEX environments
Customized solution
Fork construction re-designed
AkzoNobel's weighing stacker trucks have custom made forks, designed to pick up 1,000 kg stainless steel drums. The stacker transports the drum to a mixer that pumps the component out of the drum. During dosing, the scale continuously monitors the weight of the content of the drum. When the dosing is completed, the operator records the weight of the raw materials pumped into the mixer and returns the drum to the warehouse. The process is repeated with different components until the product mix is finished.
ATEX certified
For this application, the 4100 EX scale indicator needs a constant power supply. This version goes outside the existing RAVAS certificates and therefore had to go through a recertification procedure. Both stacker and scale were modified according to the client’s wishes and underwent a conformity inspection. Inspection authority DEKRA performed the required tests and issued the EX certificate for the systems.
