![]() ![]() Also, our install is actually “semi stayed”, this is because it was done in a bit of a rush (the wind was whipping the pole around like nobody’s business) which resulted in, to be frank, a bit of a bodge. Most cable stayed transmitters are not firmly fixed at the bottom, they’re mounted on a ball (tubular masts like Winter Hill for instance, are not). Actually, in one very important respect, they’re rather different. Scaffolds are temporary structures built to help reach work areas that are well above ground level.Guy / stay wire supported masts, your aerial pole or a TV transmitter, exactly the same principle ! See ATV's aerial array and Ridge Hill transmitter (in the picture below). ![]() Scaffolds can also be constructed as access platforms. According to the Occupational Health and Safety Administration ( OSHA) a scaffold is “an elevated, temporary work platform” (n.d). Supported Scaffolds – these are platforms that are built with strong rigid ground supports such as brackets, poles, posts, legs, frames, outriggers, etc.Suspended Scaffolds – these are platforms that are hung from a permanent solid structure such as a roof and are supported by the use of strong rope, wire, or other similar flexible materials.There are two major categories of scaffolds as explained below. These types of scaffolds can hold substantial weight. However, when designed and built, it important to ensure the structural supports are braced to avoid tilting, wobbling, or other movements. Modern times have revolutionized and added to the types of supported scaffolds. Thus, specialized equipment such as aerial lifts and scissor lifts are now considered to be types of supported scaffolds. Most of us have seen supported scaffolds in use, as these are commonly utilized by the construction industry to reach very high work areas and beyond the reach of construction workers standing at ground level. Think of the window cleaner, or those workers cleaning the exterior of high-rise towers and buildings in any part of the world! What is Scaffolding? And, with the numerous high-rise buildings around, the sighting of the two-point suspended scaffold is not an unusual occurrence. Isn’t a scaffold and scaffolding the same? Yes, it is often used interchangeably and as befitting the context requirements of a sentence. However, scaffolding also refers to the different parts such as platforms, poles, ropes, wires, ties, guys, connectors, etc. that are put together to make a scaffold. ![]() Hence, when we speak of scaffolding, it can also mean all the components of a scaffold. People who work at heights will often talk about and hear about scaffolding safety. This is because OSHA has developed regulations and recommendations that employers (who expect employees to work on scaffolds) must follow. The aim is to provide detailed guidance on the safe and secure use of scaffolds to minimize the hazards associated with scaffold use. It must also be noted that the regulations aim to protect the safety and health of employees involved in erecting, disassembling, moving, operating, repairing, maintaining, or inspecting scaffolds. The major hazards associated with scaffolds are falling, being struck by, electrocution, and scaffold collapse. Using guardrail systems, toe boards, fall arrest systems, ensuring scaffolds used are designed and build according to specifications, using recommended lumber and other platform materials, ensuring to maintain load capacity limits, undertaking regular inspections, and adopting other recommended safety measures will aid in protecting workers who use scaffolds to complete their work tasks, especially in the construction industry. However, the subject of scaffolding hazards and safety measures to be adopted is a topic for another article. The rest of this article will focus on the different types of suspended and supported scaffolds available for use in various work environments and unique purposes.įor a complete understanding of the scaffolding safety requirements, enroll in our OSHA Scaffolding Safety Training online course developed to meet the criteria set out by OSHA’s scaffolding standard 29 CFR Subpart L. Here are some of the more popular types of suspended scaffolds used today. The scaffold platform is suspended by two cables that are connected to hangers at both ends. The hangers are usually attached to a permanent structure such as a tall building, and the scaffold can be adjusted for different heights. ![]()
