Technical Data
- Allows spans of platform beams up to 5.70m, and can cover a projected area of shaft up to 30 sqm.
- Four main types of telescopic platform beams, with variable (telescopic) length to allow unlimited uses for various projects and any shaft plan.
- Can carry any formwork height, mostly up to 6.0m.
- Allowable load per support (pivot hanging shoe) is 2.5 tons.
- It is possible to lift the formwork panels with the shaft platform as one unit to accelerate the work and reduce labor and crane cost, and save working area by not lifting down the formwork. This is done by adding strong-backs connected to the panels.
- In case of adding strong-backs, the formwork is retractable to allow cleaning of formwork
- Horizontal Push-Pull props are used for adjusting the verticality of panels, and for retraction of panels in case of using strong-backs. It can also be used as an inner concreting platform by supporting timber planks above.
- Suitable for regular shape shafts (rectangular), but can also be fabricated as special frames to work with irregular or circular shaft shapes.
- Has the possibility of adding a suspended platform, to allow finishing of concrete.
Special Features
