Atlas Copco attachments tackle sensitive bridge removal.
Brazilian demolition specialist Comprex Ltda has used a range of Atlas Copco attachments to tackle an environmentally-sensitive bridge demolition contract in the city of Vitória, in the state of Espirito Santo.
As demolition debris was not permitted to fall into the waterway beneath, special arrangements had to be made for the removal of the demolition waste.
At the jobsite, three new bridges have been built over the old bridge, which was no longer able to support the increasing volume of traffic crossing between the city districts. The old bridge, comprising 1,300 m3 of reinforced concrete, needed to be removed.
The demolition sequence started by removing the light structures, such as the parapet, and concrete surfacing. This was done using an Atlas Copco SB 452 hydraulic breaker.
This process was followed by the heavier task of removing the concrete layer from the beams and finally the 10 beams themselves. Two Atlas Copco MB 1700 hydraulic breakers and two CC 1700 CombiCutters, mounted on Volvo EC 210 and CAT 416E carriers, made light work of the heavier tasks. The demolition debris was received in a special boat and transported to a recycling plant.
“The MB 1700 and SB 452 hydraulic breakers gave impressive performance on the very hard concrete,” says Comprex owner Ronaldo Zucchi. “The efficient combination of Atlas Copco hydraulic breakers and CombiCutters gave us the confidence to accept the challenge and was a decisive factor for us in winning the contract from the City of Vitória.”
