PRODUCT REPORT | LIGHT CRANES
so changing and adding sections is easy. Workstation cranes can have many different configurations – as monorails, single- or double-girder bridge cranes and so on – and steel and aluminium systems can be combined. You could, for example, have steel profile overhead track for long, unsupported runs, giving way to aluminium nearer the site of operations. The aluminium system is also available in versions for hazardous environments. As we have said, a huge variety of
different lifting systems can be mounted on these tracks. As well as its C-series Konecranes particularly suggest its CLX and SLX electric chain hoists as particularly compatible. The SLX has a capacity of up to 2,500kg with a stepless inverter; the CLX can double that load, raising up to 5,000kg with two- speed controls.
Konecranes also has its XM light crane
system, which can lift up to 2.0t. It handles loads of up to 2.0t. The overhead rail has a dip galvanised hollow profile to protect components from dust and dirt. The modular design bolts together without welding, so can be expanded easily. The rails are of steel, which allows long spans between supports, so reducing costs and optimising the working area below the crane. The rails can be configured as monorails or as single- or double-girder cranes
PROFILES Erikkila, part of the Kito Crosby Group, have its Kito Erikkila light cranes, with track profiles available in steel or aluminium as hoist tracks or in single or double girder cranes. The maximum rated capacity of its single girder steel crane is

1,500kg, and of aluminium it is 1,000kg. In double girder form, the figures are 2,000kg for steel and 1,000 kg for aluminium. The two can be combined to cater to individual needs. Double girder construction increases the lift height and the crane’s rated capacity. All of the standard light cranes can be manually operated or equipped with electrical movements for the trolley and bridge. The aluminium profiles 4/180 ICR and 5/220 ICR and steel profiles S200 ICR and S260 ICR are equipped with an internal conductor rail to maximise the crane’s coverage. The trolleys for the steel profiles are designed to minimise rolling resistance and have a maximum load of 800kg for one trolley, with a steel body and integrated buffers. Trolleys for aluminium profiles carry a maximum load of 600 kg. In use, the trolleys centralise the load
automatically to the correct lifting position, which minimises the swing of the load. Switches and turntables are available for hoist tracks – they can be mounted on free-standing pillars if ceiling support is impossible. Jib cranes are another option for light lifting. The jib cranes come in wall-mounted, column-mounted and low-headroom versions. Wall-mounted versions tend to be cost-effective since they need no support other than the wall of the building. They are also economical regarding space, so they are typically used when floor area is at a premium. Erikkila’s wall cranes have a load capacity of 1,500kg.
