The demolition must always be very well thought out. In some types of buildings, which are already designed for demolition, first of all, a massive steel ball was used, which is placed behind a very strong chain to the crane. With its weight and strong swing, it is particularly effective against masonry and similar obstacles to fall on the ground.
There are other suitable helpers
With demolition, everyone will surely present powerful machines with powerful power to demolish anything and a mercilious goal, leave nothing behind. However, sometimes specialised businesses will encounter smaller dimensions of buildings or tall chimneys, heading up to the clouds to be demolished. In this case, very effective assistants are all sorts of explosives that never leave a stone on the stone.
