Acrow props have become indispensable equipment in the construction industry. They are primarily used to provide temporary support to scaffolding and allow workers easy access to the building during construction or repairs. Acrow props that are used for tall scaffolding can pose a risk to workers if they are not erected correctly. Here are some questions that you should ask yourself when setting up this equipment to determine their stability and prevent accidents on the construction site.
Is the ground solid and stable?
Acrow props usually bear the weight of the scaffolding, workers, and some equipment used for construction. For this reason, they should always be erected on level and solid ground. If they are erected on uneven or soft ground, they can lose stability, and the structure will collapse. Place the sole plates at the base of the acrow props on a stable surface with concrete covering. If the ground is not stable, you can use wood blocks and concrete to create a stable surface. Place the props on the wood blocks and have them supported on either side by concrete.
Are the props properly secured?
Ideally, the structure that's being supported by the props should not just be resting on them. It should be secured to the surface of the plates with nails. Before securing the structure, ensure that the acrow props are locked in place with the bolts that come with it. Once this is done, drive long nails through the scaffolding and into the heads of the props. They should hold the structure securely and prevent collapse as a result of movement.
Do you need diagonal reinforcement?
Besides the weight of the scaffolding, acrow props are usually subjected to horizontal forces, such as strong winds, which can cause them to sway and lose their stability. You can prevent this by providing diagonal supporters for reinforcement. The extent of exposure of props to horizontal forces is based on the type of environment. For instance, when used indoors, there are no risks of winds; therefore, you may not need reinforcement. However, when using them for external construction projects, you will need supporters.
Is the weight evenly distributed?
Uneven distribution of weight on the props can cause them to buckle and bring the entire structure to the ground. Ensure that you do not put too much weight on one area but distribute it evenly. If it's not possible to achieve this, you can use another prop to provide additional support and take on the extra weight.
These questions should guide you when erecting acrow props to support scaffolding and ensure the stability of the structure. Make sure that you get props in the right height and weight capacity depending on your construction requirements.
