SECTOR REPORT Ӏ TRUCK CRANES
mounted on a Volvo chassis,
one with triple rear axles. The steered trailing axle gives the carrier a very small turning radius. Tadano will also mount them on similarly-axled Scanias. The HK 4.070-1 has an
H-style outrigger system and five outrigger bases, which make the machine extremely versatile at tight work sites; the Tadano Smart Chart intelligent control system gives combined main boom and rooster sheave operation. Though the crane is rated as 70 tonnes capacity, “the system increases the available lifting capacity to the point where we can even use the HK 4.070-1 for lifts in the 80-tonne class,” says Pluimers. Sylvia Fredeweß is dispatch manager at Cloppenburg, Germany-based truck crane
rental firm Härzschel. It, too, runs the Tadano HK 4.070-1. “Its low axle loads mean that we can use the crane without the need for a permit in our region,” she says. “Together with its large lifting capacity and long reach, this makes it way more versatile than the vast majority of cranes out there.” For Härzschel, another crucial advantage is the commercial truck chassis, which makes it possible to get spare parts quickly and cost- effectively if necessary. “This crane will enable us to
cover an incredibly large range of jobs – from machine relocation projects, through roofing and ceiling work in the construction industry, all the way to work in anaerobic digestion plants,” Fredeweß explains. To prepare it for the latter
Netherlands- based Herms is the first crane service provider in the country to secure a delivery of the Tadano HK4.070-1 truck crane
assignments, Härzschel has equipped its HK 4.050-1 with a load view camera that makes it easier for operators to empty anaerobic digester tanks and do these jobs faster and safer. The crane has a 70t capacity and a 41m main boom length with up to 15.8m of extensions. Its smaller brother, the HK
4.050-1, has 35.2 m main boom with nine metres of extension. Bernd Brielmann, managing
director of Mössingen, Germany- based crane service provider of the same names, uses its HK 4.070-1 primarily to assemble prefab homes and basements, as well as to set steel and concrete components in place. His is on a Scania chassis: “It gives the HK 4.070-1 the same fuel efficiency as a normal truck, and it
