Jost JTL 68.4 luffing crane without tower top
With the standard Jost tower TH 12.2 a freestanding tower height of 42m is possible. Only two trucks can transport the entire tower crane with 40m jib, 24m tower and cruciform base (although without ballast).
The JTL 68.4 comes in two different configurations, either with a 15kW or 22kW hoist unit. Both the hoist units and the hydraulic ram are frequency-regulated.
The model shown at Bauma 2007 has a maximum jib length of 55m with a tip load of 1.7t. The maximum load is 8t.
