Guide to Mobile Scaffolding

A mobile scaffolding system has been devised for builders who require a simple and extremely efficient temporary structure that is mobile and that ensures complete safety when working for heights.

A tower scaffold is an system that consists of four vertical frameworks that have been connected to create one scaffolding bay. This bay holds up a platform in which workers can have a stable base to work from.  

Suspend Scaffolding

Construction and site supervisors consider all erected scaffolds as temporary structures. Scaffolding systems allow for a fast construction and disassembly of all components, including the cross-members, braces, ladders and the platforms themselves. A mobile scaffolding system is a structure that may renounce some of these other standard elements of a traditional scaffold to allow it to become mobile.

One of the most important and crucial factors and the highest safety feature of a mobile scaffolding system is its ability to be stable. The type of stability that is required must accommodate the casters and other various forms of wheels, and their aids to ensure that the framework can be safely moved from one workplace or site, to the next.

Our guide to safe mobile scaffolding:

It is important to ensure that a licensed and qualified mobile scaffolder handles the erection, adjustment and dismantling of a mobile scaffolding system. This is especially the case where there may be a risk that any person or object could potentially fall 4 or more meters from either the platform or the structure. Although this means that is a scaffolding system has a height of less than 4 meters, does not require a licensed scaffolder, they may still be required to ensure that stability and safety of the structure, or the work should be carried out by a competent and experienced person.

For tower and mobile scaffolding systems, the following control measures should be taken to ensure optimum safety of all workers and personnel on site:

  • Begin by constructing a standard tower scaffold that has been assembled with modular, frame and coupler scaffolding.
  • Establish the scaffold on level, stable ground that is firm and ensure that the feet or wheels of the structure are properly supported. It is important that you do not use loose items, such as bricks or building blocks, to take the weight off the scaffold and secure it in place. If you are using adjustable wheels, ensure that the surface does not exceed a slope of 5 degrees.
  • The scaffold height should not be higher than the multiple of the dimension of the base.  
  • Use an internal ladder that is secure and contains a protected opening. This internal ladder should independant of the supporting surface.
  • Be assured that the correct sized wheels have been chosen and installed correctly to the proper size and capacity in order to support the mass of the dead and live loads on the scaffolding system. When the structure is at uneven heights or unlevel ground, wheels that have adjustable legs should be adjusted and secured accordingly to keep the scaffold even and safe to use.  Keep the brakes on the wheels locked at all times, unless transporting the scaffolding system from one site to another.
  • Ensure that all guardrails, midrails and toeboards have been properly installed and secured on all working platforms.
  • All work should never be completed from an adjacent locations, such as balconies or other raised areas, unless the scaffolding system is securely fixed to the external structure to prevent movement and reduce the chance of injury.

Before moving or relocating the mobile scaffolding system:

  • Be sure to check that there are no workers, other personnel on site or materials are on the scaffolding system. It is also important to inspect that where are no interfering electric lines or any other obstructions from overhead or below the scaffold in the projected line of travel. Even contact with a minor obstruction, from the ground or above the structure, can cause the scaffold to overturn or topple over.
  • Check that all electrical equipment has been properly stowed or moved to ensure that no lead can become tangled in the scaffolding system.
  • Do not attempt to move the mobile scaffold in windy, or unpleasant weather conditions. As these mobile scaffolds contain components that are not permanently fixed, this structure should only be moved in the frames that have been designed to lift individual components.

We have created a simple step-by-step guide to ensure a safe erection of a mobile scaffolding system:

  1. Fit the castor wheels into the base of the scaffolding frame.
  2. Attach the horizontal braces into the vertical tube that is found at the base of the frame.
  3. Attach the free end of the brace to the other base frame. Attach the second horizontal brace in the same position on the other side of the frame.
  4. Secure the plan brace diagonally in a horizontal direction in the base frame. Repeat this step with the opposite corners with a separate second plan brace. These should now form an X shape when analysing it from a bird’s eye view.
  5. Ensure that the unit is level and secure diagonal braces and the base of the structure is now complete.
  6. Next, insert the rinser frames to the base frame. Continue this process until it carries up to the level of the working platform.
  7. Insert and secure the working platform.  
  8. Two horizontals are then clipped to the transom above the level of the working platform. Repeat this step on the transoms 3,2 and 1 rungs above the working platform.
  9. Repeat steps 6 & 8 until you have reached the uppermost platform.
  10. Fit two diagonals above the top working platform.   
  11. Ensure that you securely fit toeboards.
  12. Fit an internal ladder to each scaffolding level.
  13. Check and securely ensure that all 4 wheels have been locked into place.
  14. To dismantle the scaffolding system, reverse the method of that of the erection process.
