PERMISSIBLE VALUES FOR SHORING
Between Old & New Brochure
Variables and assumptions:
1. Base plate type.
2. Bay dimensions.
3. Height.
4. Spindle extension.
5. Horizontal force.
6. Standard place (Middle/External).
7. Lift height.
8. Bracing configuration.
Technical Brochure 2010
Assumptions and consideration:
1. Base plate types:
Adjustable base plate 60.
Adjustable base plate 80.
2. Lift height: 2 meter considered only.
3. Bay dimension (bay width): where the optimum values correspond to bay width 2.072 (the
diagonals almost at 45 degree).
4. Spindle extension:
Spindle Ext. ≤ 5 cm.
Spindle Ext. ≤ 25 cm with scaffold brace of spindle base in the diagonal bays.
5. Bracing configuration:
Every Second bay.
Every third bay.
Technical Brochure 2015
1. Base plate types:
Adjustable base plate 60.
Adjustable base plate 60 Solid.
Adjustable base plate 60 Swivelling- reinforced.
Adjustable base plate 80 reinforced.
2. Lift height: 2, 1.5 meter considered, and 1.0 meter lift considered also for base plate 80
reinforced
3. Bay dimension: Only 2.57X2.57 in birdcage considered.
4. Spindle extension:
Base plate 60 : each 5 cm specified up to 39 cm.
Base plate 60-swivelling: each 5 cm up to 31.5 cm.
Base plate 80- reinforced: each 5 cm up to 51 cm.
5. Bracing configuration: Not specified
6. Horizontal force:
Combination of vertical and horizontal forces.
Horizontal force (perm.) in case of zero vertical.
Value for 2.57 X 2.57 – 2 m lift :
Spindle 5 cm
Base plate 60
Zero horizontal force
Old Brochure: Exterior Standard 38.8 kN (Bracing every 2nd bay
New Brochure: 39 kN
Conclusion:
The new brochure will be used in case of considering the horizontal forces or when we are using 1.5
or 1.0 lift where the capacity can reach 69 kN using base plate 80 reinforced.
