Truck crane manufacturer Emminghaus Maschinenbau is planning an export drive outside of its native Germany and is targeting the UK in particular because of favourable exchange rates.
Emminghaus wants to sell its cranes and construction material elevators either direct or through agents, said Volker Schwarz of the company’s sales department.
The 40-year-old company offers four models of truck-mounted straight boom telescopic cranes with telescopic jibs to reach roof tops. Applications are primarily to place building materials, particularly for roofing, where they are needed.
The E30 model, which features aluminium boom sections to save weight, is its best selling and largest crane model. About 80 units have been sold since its 1996 introduction.
Using aluminium saves about 3t over an equivalent steel version, Schwarz said. The aluminium boom, which is ALZN4,5MG1 grade, has a load capacity comparable with steel, he claimed. A steel crane with the same reach and capacity would have to go on a carrier larger than the E30’s 7.49t GVW truck, the maximum that can be driven with a basic full driving licence. As well as needing a goods vehicle driving licence, a larger truck costs more to buy and run, and is less manœuvrable in tight spaces.
Some steel is used in the crane, however. The turntable and chassis are made from hollow profile section ST52 grade.
Hydraulic power comes from a PTO driven pump on the truck, slewing is continuous and maximum reach is 33m, achievable with 26m of fully extended main boom and 6m of offset jib.
The outriggers are adjustable separately to a maximum width of 5m and there is six channel proportional radio control.
Maximum capacity of the E30 is 1t at 3m radius and Schwarz says that a 2t capacity model might be introduced next year.
Schwarz said that since Emminghaus began building cranes in 1995, growing numbers of roofing contractors have switched from using elevators to cranes for lifting their building materials.
