Craneable Scaffold Structures | How Scaffolders Save Time & Money Using Them

We sometimes get asked, why are your spigots double bolted when one bolt achieves the same thing?

Proscaf spigots are bolted to our standards with two M12x65 bolts meaning they can be used for propping, hanging, cantilevered, and craneable scaffold structures.

Our customers find that one advantage of partnering with Proscaf is its versatility, with each standard able to be used on the simplest residential jobs, right up to the most complex designs. The all-in-one capabilities of these standards are the key to Proscaf’s popularity across all aspects of the scaffold market, reducing the amount of gear scaffolders need to complete a wide range of jobs.

In particular, the double bolted locking properties of Proscaf makes it the ideal system to use in creating craneable or suspended structures. Component load rating data, such as the hanging capacity of the legs and tension on the ledgers and braces, are used to verify craneable or hanging structures. Below are some examples showing how Proscaf structures can be lifted. SafeSmart Access can be contacted for technical data on lifting components at any time.

Utilizing the Craneable advantages of Proscaf means efficiencies around site are maximized. Below is an example:

Nowra Bridge in NSW, Australia

During this project Proscaf was used to save the contractor significant expense. The stair towers that wrapped around the formwork on the bridge columns were able to be assembled on the bank of the river, then craned onto a barge to encapsulate the headstocks. With these structures able to be craned between barges, the time saved not having to dismantle and re-erect the scaffolding on each barge was extensive. Being able to erect the scaffold on the banks of the river was also safer and kept everything out of the way of the contractors on the barges.

Craneable structures are best utilized where there is a lot of repeat access requirements, such as access to headstocks on a bridge. Craning a scaffold around site means that contractors are able to get away with erecting and dismantling once, over against stripping and re-erecting the scaffold each time it needs relocating. These scaffolds are also best utilized where access to site is compromised, such as the job mentioned above.

Being able to assemble a structure where there is space, then crane it into position ensures that tight sites are not compromised during the erection and dismantling phases. Those who have utilized Proscaf’s double bolted standard to achieve this say that they have diversified their approach to the market, saving their customers significant expense, and creating loyalty along the way.

The most common craneable scaffold structures are Z-Stairs and Stretcher Stairs.

Features & Benefits of Proscaf Craneable Z-Stairs

  • With a stair tread width of 600mm, Proscaf Craneable Z Stairs are ideal for construction site foot traffic.
  • The footprint of these stair towers is 1.4m x 1.57m. This makes them ideal for use on even the most space restricted sites.
  • Proscaf Craneable Z Stairs can be used in conjunction with other products such as AdjustaStairs to allow for varying heights of egress.

Features & Benefits of Proscaf Craneable Stretcher Stairs

  • Proscaf Craneable Stretcher Stairs are ideal for scenarios with high levels of foot traffic, or where stretcher access is required; for example, at the early excavation stages of a project.
  • Available with construction compliant or public access compliant treads and fixtures.
  • Also able to be configured as hanging stairs.
