A full 50-litre steel cylinder weighs around 75 kilograms and stands over one and a half metres tall. It sits packed tight in the pallet, has to be taken out, moved and secured again. The usual route – tip it, roll it on its rim, heave it upright – is also the most dangerous.
Take it out of the cage pallet, bring it to the point of use or the cylinder store, stand it up there and secure it against falling. The cylinder is narrow, tall and top-heavy; its centre of gravity sits at around forty per cent of its height. Recovering a tipped cylinder takes a person's whole body. And there is what makes the mistake expensive: a valve knocked off a full cylinder releases two hundred bar. That is why the cap is mandatory – and why taking the weight is not enough; the handling has to guide the cylinder as well.
A cylinder mount encloses the body positively below the centre of gravity and keeps it upright while lifting. That removes exactly the movement in which most accidents happen: tipping and recovering by hand. On a mobile articulated-arm unit the cylinder can be lifted out of the pallet, guided over the rim and set down upright at its destination – in one continuous movement, without an intermediate stop.
Unlike series assembly the route here differs every time: to the store, to the welding bay, down the laboratory corridor. A stationary unit does not cover that. A mobile articulated-arm unit with generously sized wheels and no anchoring is the fitting design – stability without outriggers matters, because otherwise every station would begin with setting up.
Where acetylene, hydrogen or propane are handled there is as a rule an explosive atmosphere. The unit then has to match: pneumatic instead of electric, defined resistance to earth for wheels and mount, no spark-generating material in the contact area, marking and declaration of conformity. With argon, oxygen or nitrogen that falls away – there the question is not the zone but stability.
Yes, with a suitable mount. What is not permitted: slinging rope or chain around the valve, cap or neck ring. The mount has to enclose the cylinder body positively and be secured against slipping out. Rolling on the rim over short distances remains permitted but is the movement with the highest risk.
An explosive atmosphere has to be assumed; the operator classifies it in the risk assessment. We supply the unit to match the zone: pneumatic drive, conductive wheels, suitable materials, marking and declaration of conformity. With inert gases and oxygen that requirement does not arise.
For transport on level ground the trolley is enough. It does not help with what causes the strain, though: taking the cylinder out of the pallet and standing it up. Where several cylinders are moved daily the lifting unit pays for itself – through the absences avoided rather than through time.
