Tadano Faun a positive choice for green living

With the project, Helfrichsgärtel III, the community of Biblis in southern Hesse aims to generate more energy in every house of the residential area than is consumed per year in an average German household.

The positive energy balance is based on up-to-date photovoltaic systems, the latest systems engineering, and excellent building envelopes—the latter being the reason for Weiland Kran & Transport coming into play.

Weiland Kran & Transport is already working on the ninth house on the 3.7ha construction site. Their job is either mounting pre-fab elements or positioning complete pre-assembled garages. Slewing tower cranes are not an option here, as they do not pay off with these intermittent operating periods.

The ATF 70G-4 had to set down the walls for the first floor—pre-fab elements of an average length of 9m and a weight of 4.2t—exactly in the positions intended for receiving them. The lifting height required for this job was 30m, the maximum boom length 30.1m, the counterweight 12t.

For each element, the lifting procedure lasted five minutes at most. During the necessary procedure to fix the wall element to the floor plate carried out by constructions workers, the crane operator Gunter Lautenbach had a rest period enabling him to save fuel at the same time. The reason being that, owing to the two-engine concept, only the performance-adapted superstructure engine had to run during the entire job on the site.

Sebastian Degenhardt, junior manager of Weiland Kran & Transport, commented on the use of the ATF 70G-4: "For us, the total package made up by product and service must be just right. In this, the 70t crane sets an example in its class. In the taxi version, it also possesses the flexibility required for demanding jobs. Beforehand, we had considered very carefully, by using load plans and crane surveys among other things, how to use the crane optimally to help our customers to save unnecessary costs. In addition, the 70t crane is an operationally reliable crane owing to its rugged design. This is an especially important feature for us. We have to coordinate many jobs. We have no use for downtimes of our cranes."

Nine years ago, Weiland Kran & Transport had already purchased a Tadano ATF 65G-4 for its fleet. Now, following an ATF 70G-4 in March 2018, yet another new Tadano—an ATF 60G-3—will be received in April 2019.
