Acrow Prop

Acrow Prop Components in Detail
Prop Head: 150 x 150mm plates with holes for securing to timber beams or facilitating the use of accessories.
Prop Inner Tube: 48.3mm O.D. tube (standard scaffolding tube size) with holes at 152.5mm centres. Tube diameter enables standard scaffold tube and couplers to be used for bracing purposes.
Prop Outer Tube: 60.3mm O.D. Bottom plate identical to prop head. Reduction couplers enable standard scaffold tube to be connected to outer tube for bracing purposes.
Thread: On the outer tube the thread provides the ability for each prop to have infinite adjustment within its given range.
Nut: Self-cleaning nut has a hole located at one end for easy turning when prop handle is near walls. Additional nut can be added to convert prop to push-pull strut.

EXAMPLE
PROP HEIGHT 2700        Use No. 1 Prop for safeload of 21KN 
                                       Use No. 2 Prop for safeload of 26KN 
                                       Use No. 3 Prop for safeload of 31KN

NOTES TO TABLE
We advise a prop loading limit of 31KN solely for ease of striking.
Safe working loads are based on props being truly vertical and loaded concentrically.
Safe working loads have been derived from tests and a minimum factor of safety of 3 to 1 applies.
Note that the safe working loads are for unbraced props.
