Anthron is a small company, run by family Lorbek since its foundation in year 1989. Anthron is the Greek name for cave and actually our first products were destined for speleologists. The thread of our activity, however, is rescuing both in the field of sports (speleology, mountaineering, free climbing) and in the field of selected industries (fall protection and rescue equipment). And what was the motive for embarking on this rather specialized activity? The very impulse goes back to the year 1977; at that time our family resided in a twelve storey building. Suddenly the earth began to shake, the first earth quake was followed by several subsequent ones , and the tenants, panic stricken, began in mass leaving their flats, jostling the narrow flight of stairs towards the exit. Among them, carrying his two little daughters was also Joze Lorbek, a young mechanical engineer. Since then he never stopped pondering on how to make in the case of elementary disasters the evacuation of people from such high buildings easier, safer and more effective. And thus an idea occurred to him which was a few months later followed by proto-type of a self rescuing device ST-777, his first innovation.
