PFAFF-silberblau has introduced new lifting equipment for ATEX areas in zones 1 and 2 or respectively category 2 and 3: the wall-mounted rack and pinion jack ZWW Ex, and the hand wire rope winch Omega Ex for use in potentially explosive areas.
The wall-mounted rack and pinion jack owes the expansion in its range of applications to the use of carefully selected materials and top quality coating.
These prevent any mechanically induced sparks from being generated. All the individual components are designed from an electrical engineering point of view in such a way that the surfaces can not heat up unduly.
Equalisation of potential and surface restriction prevent the wall-mounted rack and pinion jack from becoming statically charged.
The ZWW Ex can lift, lower, pull and push, move horizontally, support, adjust or fix loads of up to 250 kg — such as heavy components or whole instruments and machines.
A lubricated, self-locking worm gear is set in motion by turning the crank handle, thus not only moving the load with ease, but also reliably securing it in any position.
The wall-mounted rack and pinion jack ZWW Ex is suitable for ATEX areas in category 2 (= Zone 1/21) and category 3 (= Zone 2/22) and is labelled Ex II 2 DG c 195°C (IIB T3).
Category 2 includes equipment that provides a high level of safety even where disruptions are expected. Category 3 covers equipment which provides a standard level of safety when used normally.
Hand wire rope winch
The hand wire rope winch Omega Ex is also Ex-protected.
It has been especially developed for the high safety requirements in potentially explosive atmospheres (ATEX protective zones 1 and 2) and is available with three different loads — 400kg, 630kg and 900kg — and a lifting height of 10m.
It is particularly used in critical environments in which there is a potentially explosive atmosphere, such as in the chemical or petrochemical industry.
