![]() ![]() These types are rarely used due to their relatively special application range.Adjustable suspension scaffold means a suspension scaffold equipped with a hoist(s) that can be operated by an employee(s) on the scaffold.īearer (putlog) means a horizontal transverse scaffold member (which may be supported by ledgers or runners) upon which the scaffold platform rests and which joins scaffold uprights, posts, poles, and similar members.īoatswains' chair means a single-point adjustable suspension scaffold consisting of a seat or sling designed to support one employee in a sitting position.īody belt (safety belt) means a strap with means both for securing it about the waist and for attaching it to a lanyard, lifeline, or deceleration device.īody harness means a design of straps which may be secured about the employee in a manner to distribute the fall arrest forces over at least the thighs, pelvis, waist, chest and shoulders, with means for attaching it to other components of a personal fall arrest system. They are also a cheaper option than mast climbers, making them an economical option for when you want a moving platform scaffold. They are relatively easy to set up and highly customizable. The brackets can be raised or lowered in a way similar to a jack used to lift up a car. This design is a moveable platform on vertical poles. Mast climbers have many uses, but they are significantly more expensive than other scaffolding types. Finally, mast climbers can also be easily customized and loaded with various machinery. It also helps reduce fatigue, as contractors don’t have to stretch as much to reach various heights. This helps reduce back and neck strain on workers. Due to their adjustable platforms, they can be finely positioned. They also have guard rails, which help reduce worker injury and falling equipment. Because they have smaller bases, they can be used in situations where ground space is limited. Mast climbers are surprisingly versatile scaffolds. For lower heights, mast climbers can be based on mobile platforms. They can be freestanding, but will often be tied to a structure to achieve better heights. Mast climbers are moving platforms that can be raised or lowered along with a strong scaffold structure (the mast). Of course, given their minimalism, they are best used for lower-weight applications. ![]() This makes them extremely mobile, cheap, and usable in different situations, hence their widespread use. These are simply constructed by resting a platform on brackets attached to a ladder. Just about every commercial contractor has seen this type of scaffold. However, this also means that they can be difficult to correctly - and safely - assemble. Finally, tube and coupler scaffolds are highly versatile, because they can be assembled in various directions and shapes. They are heavy-duty scaffolds that can carry extremely high load weights. These scaffolds are built from tubes connected by coupling devices. They are used most often when the loads they need to support are lighter and when other scaffolding is not feasible or available. Because these scaffold types are made from scratch, and out of wood, they are not used as frequently in modern buildings. Double-pole scaffolds are supported by two poles that go vertically and are independent of any structure. Single-pole scaffolds receive support on their interior side from a structure or wall. There are two main types of pole scaffolds: single and double. Scaffolds in which the entire structure, supports, platforms, and all, is made of wood. They are also used for plastering and renovating purposes like wallpapering or removing materials from walls. They are used in situations where the workers must frequently change positions. These are scaffolds often used by painters, that rest on wheels or casters. On commercial work, such as offices or industrial facilities, they may go much higher. Typically, construction contractors will use these for 1 or 2 story heights for residential work. Thanks to their modular design, they can be multiple stories tall. These legs go up to the first tier, which has a platform that workers can move freely on. They have a base section, often composed of feet that touch the ground. Fabricated frame scaffolds are the most common type because they are cheap to purchase/construct, easy to use, and versatile. ![]()
