Source

The spruce used for the construction of TimberTowers grows in native woods. The timber suppliers guarantee the ecological, economic and socially responsible management of the sources. The forest operators selected replant every felled tree to maintain a constant supply.

Advantages

Timber prices are stable and timber has a long lifetime, enables the construction of large tower feet, promotes local industry and tradesmen, and is easy to transport. The profitability of the total project increases as a result of the low costs for the tower. Environmental friendliness increases as a result of binding large quantities of CO2 and the straightforward recycling.

Processing

The sawmill makes planks of solid wood from spruce. The planks are laid over each other and glued to form cross laminated solid wood panels with a thickness of 30 cm. The panels are 3.75 to 15 m in length and have a width of 1.18 to 2.95 m. In the mill each panel is sealed over its whole surface.

False
work

Function of the falsework

The pre-fabricated falsework helps in the erection and maintenance of the tower and is fitted with all electrical elements. The timber elements are leaned against the falsework and are then bonded to each other.

The 100 metre tower falsework

The timber frame construction consists of pre-fabricated frame elements, which along with 15 m long uprights and eight platform halves are installed on site to form 15 m long segments. The lighting and ladder system, attachment points, power cable holders and electro installations of the total of six elements are manufactured in advance.

Falsework

The 140 metre tower falsework

For the erection of the dodecagonal (12-sided) tower structure this falsework is pre-fabricated on site in 15 m sections before the sections are placed on top of each other. The ring segments of the form adapter and the hexagonal tower structure are also pre-fabricated. Within each segment there is a platform as a support for the form of the segment and as a working level. All fittings for the tower like lift, ladders, power cable and lighting are attached to the falsework and are to a large extent either pre-fabricated or, on site, assembled before erection of the tower starts.

Steel
adap
ter

This adapter connects the tower with the nacelle of the wind energy plant. The round head flange of the adapter is connected to the plant pre-stressed bolts. The central part of the adapter consists of a conical steel tube with a thickness of 18 mm. The bottom flange connects via the steel mesh to which it is welded the plant to the tower.
