VIDEO: Next Level uses bespoke platform system for high-stack chimney demolition

Two reinforced concrete chimneys, measuring 100 and 150 metres in height, were dismantled at this live industrial site in the northern part of the country.

To take the structures down to the 30-metre mark, Next Level utilised a telescopic platform system from SAEclimber specially manufactured for the task, and two remote-controlled demolition robots from Brokk and Husqvarna.

The SAEclimber consisted of a large-scale elevator platform which provided a stable and secure working environment for both personnel and machinery.

Designed to adapt dynamically, the platform narrows as it moves upward and expands toward the bottom, mimicking the shape of the chimney.

With minor modifications, this system can also be applied to the demolition of skyscrapers in challenging urban conditions.

At 30 metres, a Volvo EC700 high-reach excavator with shears took over to safely and rapidly bring down the remaining parts of the stacks.

To protect the live site, all concrete debris was dropped internally through the centre of the chimneys. The falling material was contained entirely within the structure and regularly scooped out from the bottom using a standard excavator.

“When dismantling at such heights, even a small object can travel several hundred metres when falling and cause unpredictable consequences, so safety requirements were exceptionally high on this project,” commented project manager Andrejs Jenaki.

The project was executed over six months including during the freezing conditions experienced during the Baltic winter, when temperatures dropped to -10°C and averaged just 0°C.

In addition, the company maintained a zero-incident safety record despite the high-altitude risks, sub-zero weather and proximity to active infrastructure.
