Lifting systems<br />
A STICKY SITUATION?<br />
With a modular design and capable of handling weights of up to 800kg, the LiftMaster<br />
Quadro from Bohle is said to deliver a step change in safety. Total Fabricator hears about<br />
this new automatic vacuum lifting system and how it can handle the weight of expectation...<br />
Weight is a killer. Glass has become a<br />
key structural element in contemporary<br />
architectural design and on that basis,<br />
the glass the processors and manufacturers have<br />
to handle in the factory, and installation teams on<br />
site, is getting bigger and heavier.<br />
And that means risk in handling both in<br />
production and installation is also greater. “The<br />
weight per sq metre of, say, a laminated doubleglazed<br />
unit in a fairly standard 6/16/8.8mm<br />
configuration is probably around 35kg. You can<br />
add on at least another 10kg per m 2 for a triple<br />
glazed unit,” explained Dave Broxton, Managing<br />
Director of Bohle.<br />
“With 4m 2 plus units almost a standard product,<br />
there is a growing pressure to handle bigger units<br />
and heavier glass in the production environment but<br />
Dave Broxton<br />
also on site. The ability to do so safely is critical,” he<br />
continued.<br />
Cue the Liftmaster Quadro automatic vacuum<br />
lifting system, from Bohle. The first battery<br />
powered lifting system to be tested to the ultrastringent<br />
German TÜV GS mark – providing an<br />
independent guarantee of performance.<br />
It’s built around a dual-circuit vacuum system,<br />
which means the Liftmaster Quadro doubles up<br />
on safety, so if vacuum is lost on one circuit, the<br />
second will support the load.<br />
This echoes the design principles which<br />
underpin Bohle’s Veribor range, which is<br />
designed to have a minimum 2:1 safety margin<br />
to reflect real world usage.<br />
“We’re talking about the capacity to handle<br />
some really big weights here in a production<br />
environment – or out on site. You can’t afford for<br />
things to go wrong,” explained Dave.<br />
“The GS Mark, which stands for ‘Geprüfte<br />
Sicherheit’, or ‘Certified Safety’, is recognised<br />
Europe-wide. It’s peace of mind that you’re<br />
using the best equipment and a standard which<br />
we already use across our manual handling<br />
ranges”, he added.<br />
The lifting system can handle<br />
weights of up to 800kg<br />
