The method used for crane demolition may vary depending on the building materials, the purpose of demolition, the way its debris will be disposed and the area where the process will take place. Every reliable contractor must be aware of the different methods to help you choose the right technique to use when you need something to be demolished. They must also understand the pros and cons of each technique.
When the structure is smaller, hand demolitions may do. Most part of the tearing down process is performed with hand tools. However, shear legs or crane operation may be used at times to lower down and hold the beams while cutting them. The problem with this method is that this is slower than any other tactics because most of the jobs are done by an individual. This may be more dangerous as well.
Demolition by hand is only preferable on buildings with fewer stories. In line with safety regulations, the demolisher must only take down one story at a time. They have to start from the top going all the way down to the ground level. Disposing of the debris may also be more difficult.
A more advanced technique uses different mechanisms to demolish a certain structure. The ball is one of the most commonly used equipment. This is ideal for larger buildings that need to be taken down immediately. This can remove a large chunk of the building with just a blow. However, this may also be hazardous due to the vibration it causes to nearby structures, flying debris, dust and noise among others. This technique may only be performed by a real professional.
Another is the use of pusher arms. These are hydraulically-operated excavators that use different attachment for various demolition jobs. They also have loaders to collect the debris and dispose them later on.
There are some contractors who are experts in collapse methods. This is a highly crucial technique with the imminent danger it brings. In this tactic, the expertise and competence in engineering is indispensable. One has to identify the key points that must be taken off for a gentle and safe collapse. Usually, this is used when demolishing bridges, silos or chimneys in isolated or heavily secured sites.
A closely related method for the previous one uses rope and cable pulling. In this process, the certain parts of the structure are tied up to crane services. Then, the ropes are carefully pulled down to bring the building down.
The last is the use of explosives. Several providers prefer this method for crane demolition because it is cost-efficient, safe and quick. This can significantly reduce the costs and duration of the process by up to 80 percent. This includes the preparation and cleanup process. However, only experts may perform this very dangerous stint.
