Scaffold Towers: Equipment For Working At Heights
Scaffold towers, also known as tower scaffolds or mobile access towers, are widely used and can provide an effective and safe means of gaining access to work at height. However, inappropriate erection and misuse of towers are the cause of numerous accidents each year. Aluminium and thin-wall steel towers are light and can easily overturn if used incorrectly. Towers rely on all parts being in place to ensure adequate strength. They can collapse if sections are left out. Before selecting or specifying a tower, you must be satisfied that it is the most suitable item of equipment for the job.

With scaffold towers, you can work on things that are very tall in stature. Towers such as these would be perfect for professional painters, bricklayers and carpenters.
The elements that make up a scaffold have names that are specific to the industry. The vertical tubes in a scaffold are called standards. The horizontal tubes, parallel with the building, are known as ledgers. Each row of ledgers is called a lift. The horizontal tubes supported by the ledgers are known as transoms. Platforms are formed from boards supported by the transoms.
To stop the scaffold from falling sideways a system of diagonal tubes is present as part of the structure: this is known as bracing. Façade bracing is on the face of the scaffold, parallel with the building. Ledger bracing ties from the inner ledger at one level to the outer level of the next level.
