A suspended scaffolding system involves a working platform that hangs from an overhead structure. These suspended scaffolds are normally supported on all four sides with ropes. However, other means can also be adopted, such as metal chains. A suspended scaffolding system is ideal in situations where tall structures are involved. It is difficult to set up a regular scaffolding system when working on a very tall structure. Moreover, it is also costly in terms of time, money, and energy. In such a case, setting up a suspended platform, such as the swing stage scaffolding, is a wise and cost-effective solution.

If you require quick and easy access to tall buildings and structures, then an electric powered suspended scaffold is just what you need. It is a flexible scaffold that can be extended from 3 feet to 72, even more if required. Moreover, it is a lightweight platform that can be suspended easily from an overhead structure. Although it is lightweight, it can carry loads of up to 1500 lbs. Speed is another important advantage of a powered swing stage scaffold – it can quickly move personnel and materials at a speed of 35 feet per minute. Furthermore, workers can use the stirrups on the edges of a swing stage scaffold for walking therefore increasing the actual length of the platform.

Suspended Scaffolding / Swing Stage Scaffolding

They have expanded their umbrella by manufacturing and adapting their suspended scaffolding products to suit the needs of the ever-changing market. Hence, they continue to lead the suspended scaffolding market. Spider keeps its customers satisfied by offering them both sale and rental options from 25 locations across North and South America.

The suspended scaffolding system has eight types of which an adjustable two point swing stage scaffold is the most popular. Suspension scaffold is another commonly used term for this popular scaffolding system which is a very cost-effective and flexible option in rooftop projects and industrial installation. Although this article is going to look into the different types and components of suspended scaffolding systems, it will focus primarily on swing stage scaffold.

A swing stage scaffold has cables/wires connected to hangers/stirrups on each end of its platform. These cables support the suspended scaffold. An electric motor is used to raise or lower the platform according to the requirement of the situation. Although they can be configured in various ways for different purposes, swing stage suspended scaffolds are normally employed by companies that are involved in facade restoration of high rise structures.

Types of Suspended Scaffolds

Two-point (Swing Stage)

A swing stage is the most common type of suspended scaffolds. It is suspended from an overhead structure by cables or ropes that are attached to stirrups on each side of the platform. Although it is typically employed by window washers, it plays a major role in high-rise construction. A swing stage attached to the exterior of a building is a common sight for pedestrians and drivers in an urban city.

Catenary scaffold is a type of suspended scaffold that consists of a working platform supported by two parallel and horizontal ropes. These ropes are connected to structural members of a building, such as beams and columns. Employees working on the catenary must be equipped with a personal fall-arrest system to avoid dangerous accidents.

Float (ship)

A float or ship is a suspended scaffold that consists of a platform positioned on a couple parallel bearers. A ship hangs from an overhead structure with the help of fixed-length ropes. Some safety requirements must be kept in mind when working with a float: the bearers supporting a platform must extend at least six inches beyond it on either side. Employees working on the float must be equipped with a personal fall-arrest system to avoid dangerous accidents.

Interior Hung

These are similar to a float scaffold. The only difference is that a float hangs from a single beam or column, whereas an interior hung is suspended from two separate structural members.

As obvious from its name, this kind of scaffold consists of multiple levels in the scaffold structure. Each of the platforms on each of the levels is positioned on common stirrups. This kind of scaffold is useful in terms of saving time and money. Many workers can work on different levels of a structure at the same time on the same scaffold.

Multi-point Adjustable

This suspended scaffold consists of platform(s) that are suspended from the overhead structure at more than two points. A multi-point adjustable scaffold is equipped such that the height can be adjusted according to the requirement of the project. A few safety requirements must be kept in mind when working with a multi-point adjustable scaffold: they must be hung from hooks, metal outriggers, wire rope slings, brackets, or other durable means; two or more scaffolds must not be bridged together unless their design allows bridging; if not using bridges, platforms can be connected through bridges only if they are at the same height.

Single-point Adjustable

This kind of suspended scaffold consists of a platform that hangs from an overhead structure by just one rope. A single-point adjustable scaffold is designed so the height can be increased or decreased, as needed. These kinds of scaffolds can often be seen outside a high-rise building by workers who wash and clean windows. A common single-point adjustable scaffold is the Boatswain’s Chair.

Components and Accessories of Suspended Scaffolds


The most important component of a suspended scaffolding system is a motor that helps adjust the height of the hanging working platform. There are different motors by different companies that can be employed for this purpose. When selecting a hoist, the weight of the unit itself as well as the weight of personnel and materials are important factors to keep in mind.

Tractel Tirak Hoist

Born in 1941, Tractel revolutionized the industry when it manufactured hoists, both manual and electric, which enable the use of a suspended scaffold.

Tirak hoists consist of four components: rope/cable driving mechanism, gear box, electric motor, and a secondary brake. The wire rope/cable passes completely through the machine so there is no trouble of dealing with long cables. Tirak hoists can be used for any height ranging from 30 to 1200 feet, even more if required. They are equipped with either an air-powered motor, or an electric one.

These hoists are designed to make work at great heights as safe and easy as possible. That is why they are equipped with a secondary brake. In case there is a power failure, the secondary brake can be used for controlled descent, therefore completely eliminating the dependency on and need for electrical components. Tirak hoists are designed and intended for vertical hanging rope

The primary positives of a Tirak hoist include powerful but lightweight, simple but reliable, constant speed regardless of height, and emergency descent with the provision of a mechanical emergency descent device. Moreover, they lack the hassle of lengthy cables and electricity that might result in power failure or sparks.

These are incredible motors that are sure to give you years of hassle-free and rewarding service. Tirak hoists are designed such as to allow for use with all suspended scaffolding systems, including bosun’s chair, work cages, and swing stage that is the star of this article.

Safety Precautions

Swing stage scaffolds, and other suspended scaffolding systems, are employed at great height, which is why safety precautions are of utmost important.

  1. Ensure that the building or structure on which a swing stage is positioned is strong enough to carry the weight of the unit itself, as well as of the personnel and materials on the platform.
  2. Make a detailed design plan, keeping the swing stage scaffold’s design specifications, limitations of the structure, wind and other such external forces in consideration.
  3. Inspect each component prior to assembly.
  4. Components from different manufacturers must not be mixed up with each other. Make sure to stick to one company and invest in its products and accessories related to a swing stage scaffolding system.
  5. Restrain outrigger beams properly so as to prevent movement.
  6. Equip workers with fall-arrest systems whenever working on a suspended scaffold.
  7. Keep power lines in consideration when working with powered scaffolds.
  8. Follow instructions and guidelines on manufacturer’s manual or handbook.
  9. Most importantly, make sure that all components and accessories are in perfect condition and compatible with each other. Any repaired components, such as suspension ropes, can be very dangerous to re-use when employing a swing stage scaffold.

Swing Stage Scaffold for Sale/Hire

Most companies require their customers to contact for an estimate. Swing stage scaffolding equipment is available for both sale and hire by many different suppliers. However, before investing in swing stage equipment, carefully research all the manufacturers and make a wise decision. This is because scaffolding components from different manufacturers are often not compatible with each other. So, the cost effective way is to choose one manufacturer and then invest in its products.
