Features of the Staxo 40 frames
Only 24.5 kg, 18.0 kg or 15.0 kg, depending on the type of frame.
.
Ergonomic design
Ergonomically shaped – easy to carry, as it can be held at or near the frame's centre of gravity
.
Framework scaffolding with passageway opening created by inverting the frames
Turning the frames upside-down creates ample headroom for safe working inside the scaffold and beneath the towerframe superstructure.

▪ tried-and-tested interconnection system (captive)
▪ secures the diagonal crosses
▪ two defined positions (closed – open)

▪ works in both directions, i.e. on inverted frames as well
▪ also secures the diagonal crosses when towers are assembled in the horizontal, and when the frame is positioned so that the safety-catch bolts are at the bottom (rather than the top) of the frame crossbar
.
Anchorage points for personal fall arrest systems (PFAS)
|
|
WARNING ➤ Make sure that the anchorage point is at or above the required minimum height, as otherwise there will not be sufficient room to arrest a fall. |
|
Permitted anywhere on the diagonal tube of the frame. |

Prohibited on the integrated universal U-bracket. |

Linking the frames
Staxo 40 coupler
The vertically stacked frames are attached to one another by the Staxo 40 coupler with its integrated stop-ring.
Because this coupler extends such a long way (15 cm) into each frame, no extra pin-type safety locks are needed when towerframes are erected and dismantled in the upright.
A crane-handling-safe link, using a Staxo 40 tube connector d48.3mm, is required in the following cases
▪ when the towerframes are assembled in the horizontal
▪ when the towerframes are lifted by crane
▪ if there are forces acting upon the tower which cause tensile stress
|
Permitted tensile force 11.7 kN |
.
Securing the screw-jack heads and feet against pull-out
Staxo 40 anti-dropout lock (E)
A crane-handling-safe link, using a Staxo 40 anti-dropout lock, is required in the following cases:
▪ when the towerframes are assembled in the horizontal
▪ when the towerframes are lifted by crane
▪ if there are forces acting upon the tower which cause tensile stress
|
|
|
Permitted tensile force 5 kN |
.
Erecting quadratic towers
|
|
NOTICE On quadratic (150x150 cm towers), do not mix the frame plane and bracing-strut plane within the same tower! |
