The German crane specialist has maintained a subsidiary in Dubai for several years now.
The locally based R.STAHL engineers planned the crane systems in cooperation with the architects and were able to compete with international competition.
"The quality of the German components, the versatile solutions and the cost advantages afforded by local manufacture in Dubai were the crucial factors for the customer's decision." commented V.
Raman, R.STAHL's general manager in Dubai.
The bridge cranes are built in Dubai using components from R.STAHL's Kunzelsau factory.
In overseas operations, Stahl supplies the high quality machinery components from Germany, manufacturing long, heavy structural steelwork in specialised local companies.
The drive technology for Burj Dubai comes from the German parent factory, however the bridge girders, weighing almost 3 tonnes are manufactured by Stahl's partner Fabtech in Dubai.
Two of the cranes have already been installed on site in spring 2005.
Both cranes are designed for 7,500 kg S.W.L., 8,750 mm span.
The load hook can traverse the full 100 or 50 m length of the building, lifting loads in the machinery rooms up to 6 m.
On the customer's request, maintenance platforms were built along the crane bridges, so that inspections and maintenance can be performed easily and safely.
All motors are equipped with dual speeds and temperature control.
At the heart of the cranes are the electric wire rope hoists from Stahl's successful SH series.
Two 3m FEM classified SH 60 hoists were used.
The low-maintenance gears, electronic motor management and oversized brakes guarantee maximum availability and minimum wear.
The motors are designed for at least a 60% duty cycle.
The robust cast metal rope guides are particularly wear-resistant.
The hoists' true vertical lift design provides maximum convenience: the drums are equipped with two wire ropes so that the hook does not move horizontally when the loads are lifted and lowered.
The cranes are operated with HBC radio remote controls.
