A 100 × 60 × 4 rectangular tube six metres long weighs 55 kilograms. Two people can carry that. What they cannot do: lift it alone without one end dropping, lay it level on the roller table and hit the stop at the same time. That is why two people are tied up at many saws – for a part one person could lift.
Pull it out of the cantilever rack, turn it, carry it to the roller table, lay it down, set it against the stop. Long stock bends under its own weight: picked up at one point it sags at both ends and lands hard when set down. In the rack the profiles lie close together, often on several levels, and the piece wanted is rarely on top. Then there is the edge: cut ends and tube ends are sharp, and a profile slipping from the hand falls six metres onto the floor.
The whole difference lies in the load pick-up. A beam with two adjustable mounts, set at half the length apart, takes the deflection out. For steel we work with lifting magnets, for aluminium, stainless and coated profiles with clamps or positively locating forks. Where both run, a beam with interchangeable mounts is the answer – the change then takes a minute instead of a conversion.
Store, saw and stacking point almost always lie in a line. That is exactly what a monorail system is built for: it follows the route, needs no slewing space and can be led along the whole length of the store. A column unit would have to cover the route as a circle and would end up either too large or too short. Where several saws are served, an area system with main and cross girders is added.
A unit that lifts the profile but lets it crash down when placed will not be used. We design the lowering speed damped and give the mount enough play for the part to align as it lands rather than being forced. For sensitive surfaces polyurethane pads are added – scratches on a visible profile mean rework, and nobody counts rework into the purchase price.
Weightless handling – floating instead of lifting.

View deviceOn steel the lifting magnet is the fastest pick-up – approach, hold, done. It is ruled out for aluminium, stainless and coated material and needs protection against power failure. Clamps and form mounts are slower but material-independent. Where both run, we plan a beam with interchangeable mounts.
As a rule of thumb about half the part length, symmetrical to the centre of gravity. More precisely we calculate it from the permissible deflection of the profile – with thin-walled tubes and long aluminium sections the best spacing is closer than expected.
Not necessarily. If the roof trusses carry the load we suspend the system directly beneath them; that is the normal case. Otherwise a separate stanchion structure is added that stands independently of the roof. We settle both in advance with the structural engineer – not on site.
One short conversation usually settles more than three quotations. Call or write — you will reach an engineer directly.
Start typing – for example “balancer”, “SAP” or “pipe stress”.
