Crane on a city portal!
FB GRU presents at MECI 2008 show the new models of TOPLESS series, the GHS451 and the GHS501 – with jib length respectively 45 m and 50 m, maximum height achievable at the hook of 41 m, jib end capacity of 1000 kg and maximum capacity 2000 kg.
These new models are standard equipped with Inverters with three speeds on all movements, all the structural components are realized with elements of maximum length of 6 m and with certified high strength materials for the weight reduction.
In particular, these new models, other than summarize all the characteristics of the GHS series, are suitable to be installed and used in building site in which the accessibility doesn’t permit the using of the traditional cranes, like in historical centers, and therefore they represent the best solution for the restructuration in the urban area since their configuration on portal permits the transit, both vehicular and pedestrian, in order to reduce the occupation of the public ground and gain space in the building yard which otherwise is not utilizable.
Here follow some principal advantages of the utilization of a crane installed on a portal:
• The width of the passage between 2,40 m and 3,80 m and the maximum height of 4,50 m permit the transit from the small cars to the buses for the public service
• The realization of support slabs in reinforced concrete, in order to reduce the pressure exerted by the crane on particular grounds of squares and streets of historical centre, minimizes the eventual costs for the restoring.
• The adjustable stabilizers placed between the columns of the portal and the concrete slabs permit the positioning and the leveling of the crane base in every difference in height of the ground.
