Where there is a requirement for total protection of adjacent equipment or property, Bierrum have the experience and know-how to carry out controlled "piece small" demolition in a protected environment.
Bierrum has developed "The Bierrum Spider" specifically for the demolition of chimneys. The system involves just four operators and can achieve demolition speeds of up to 3 metres per shift without the use of cranes or specialist cutting gear.
Demolition of cooling towers is usually undertaken using hydraulic cutting or disc cutting methods and then lowering the cut section by crane. The Bierrum access system forms the solid self-climbing platform all round the structure to support the heavy cutting gear whilst it is operating.
