German rental company Castell Autokran has taken delivery of the first 70 tonne Tadano HK 4.070-1 truck crane after being unveiled last month - see: New Tadano truck mounts.
The first unit has been mounted on a Volvo chassis, the HK 4.070-1 features a five section 41 metre main boom plus a nine metre swingaway extension. Fitted with 10.1 tonnes of counterweight it can handle 55.6 tonnes at a three metre radius and 19.2 tonnes at an eight metre radius.
Its outriggers are regular beam and jack while the extension is variable and asymmetric with automatic monitoring and load chart selection. It has an overall length of 11.8 metres, an overall width of 2.55 metres and is under four metres high. The front and fourth axle steer, while the second and third axles are mounted closer together in the centre of the chassis. The company claims that this not only provides it with the best turning radius in its class but that its turning radius is up to two metres smaller than its HK 70 predecessor.
Managing director Nils Prüfert, said: “Its ease of handling and enormous versatility made the HK 4.070-1 the natural choice for us. The places where we work are often really narrow and steep. And that’s not just at the work sites themselves, but also on the way there, so we need manoeuvrable cranes that can get around without a problem even when space is tight – that’s what the Tadano HK 4.070-1 is.”
Established in 1952, Castell Autokran runs a fleet of cranes ranging from 30 to 250 tonnes from its location Koblenz, western Germany. It also has a fleet of telehandlers, forklifts, loader cranes and transportation vehicles.
