The innovative pendular counter-ballast system sharply minimises the forces in the tower. Impressive freestanding tower heights are therefore possible: 128 m on a foundation anchor and 97 m on a mobile portal.
The WT 2405L e.tronic Luffing Jib Crane
|Max. radius||78.0 m|
|Load capacity at max. radius||19.5 t|
|Max. load capacity||128.0 t|
|Max. hook height freestanding *||147–205.5 m|
|Number of strands||2 to 8|
|Hoist gear power||140 or 280 kW|
|Connected load||325 or 465 kVA|
* The values correspond to the hook height with the longest jib in the lowest and highest position at the tallest tower height.
Here, the task of the WT 2405L e.tronic was the chimney modernisation in a densely built-up area: The existing filters had to be replaced by new, better performing filters at dizzying heights. The crane was assembled at a low height and then erected by crawling for this purpose.
