You’ve probably seen them before – the temporary work podiums that construction workers use when they’re completing work above ground level or on uncompleted building floors. These temporary podiums are useful for all types of construction work and come in a variety of styles to suit many different purposes and needs. From heavy-duty to simple jobs they are versatile and used by all types of industries. One type of this platform is known as the ‘mobile scaffold’.
What is a mobile scaffold?
A mobile scaffold is a temporary platform that is usually set up on casters wheels and used for certain types of construction works. The structure is movable and often used in projects where the worker needs to regularly change their position, such as when painting or plastering a building. They are often safer and more stable than simply using a ladder, which helps to ensure the safety of employees. They are very portable and easy to take from job site to job site which makes them an effective and efficient tool for a variety of businesses and needs.
What are the types of mobile scaffold
The most common choice of mobile scaffold is known as the single bay tower, a platform that is supported by casters. These varieties can be easily and quickly assembled with coupler and tubes, modular piping and a frame. These handy platforms can be easily and quickly customised according to your specific needs and preferences. These mobile scaffolds are designed for heavy construction work and so it’s very important that a number of safety procedures are followed to ensure the safety of workers.
Safety measures to follow with mobile scaffold
- Avoid the structure collapsing or ‘racking’ by securing the frame of the structure with diagonal or horizontal braces, or a cross brace as this gives more support and opposing force to the structure, which helps it to carry the weight of the worker.
- Ensure any brace connections are attached properly and that the structure and connections are flat and precise.
- Your structure will be movable on casters, which means safety is very dependent on the casters. Check that caster have the correct swivel locks and are sturdy enough to prevent unwanted movement whilst on the trolley
- If you are planning to move the temporary structure, ensure you do not apply force or attempt to shift it above 1.5 metres as this can cause accidents.
- If the structure is being moved, workers should not step onto it as this can cause falls.
- If the structure does not have supportive outrigger frames then the podium should be smaller than the base of the structure
- Before workers begin work, the casters and wheel stem should be carefully checked. The casters should be screwed in tightly and have secure connections to the legs of the structure to prevent unwanted movement or racking.
Design of the structure
Any mobile scaffold should have a height that is no taller than four times the base width of the structure as if it’s over the structure cannot be tied for additional support. Outriggers can be added to the structure for wider area support.
Horizontal and diagonal braces on the temporary structure can be added at about every 6 meters, they should be carefully pinned in to avoid racking. If there are not enough horizontal and diagonal braces added then a forged base with hooks can be used in its place. Side brackets cannot be used on these structures and the platform should not be wider or go further than the footprint of the base.
