The Stöcklin Group is currently manufacturing explosion-protected industrial trucks of the type "EXP20" for a longstanding customer in South Korea at its technology center in Laufen, Switzerland. According to the manufacturer, the vehicles are intended for explosive areas of zones 1/21. In addition to the technical requirements for explosion protection, the company must also consider international certification standards and national approval requirements. European ATEX conformity alone is not sufficient for the use of the devices in South Korea.
