Conversion according to customer requirements
For the second 2x10t gantry crane that was delivered to the German concrete manufacturer, an existing gantry crane in tubular construction was refurbished and rebuilt to meet the customer's specifications. Among other things, the span of the crane was reduced from 62m to 42m and the load capacity of the crane was increased from 10t to 20t. In addition, the lifting height of the crane was increased from 10.5m to 14.5m.
For the transport by truck, the almost 70m long crane bridge was split into two parts and welded back together on site.
Optimization of the wheel loads
On explicit customer request and in order to not damage the concrete foundation of the storage area, the maximum vertical wheel loads per impeller could not exceed 16t (160 kN). In order to comply with this requirement, new crane chassis with 4 wheels per chassis corner were designed to distribute the resulting forces accordingly.
Complete overhaul at TEICHMANN CRANES in Essen
Both gantry cranes that were delivered to Leonard Moll in Biebesheim have been completely refurbished and overhauled electrically and mechanically. Both cranes were equipped with each cabin controls as well as a radio remote controls which allows the cranes to be controlled both from the cabin and from the ground. The two 28m high TEICHMANN cranes can travel at a maximum speed of up to 80m/min and can lift up to 20t each.
