TECHNICAL DETAILS
1-14 MSHF • 7295-026A
1.8 Anchorforces
Torque scaffold coupling: 50 Nm / 37 lb ft.
With the calculation of the anchor forces
show in the table the following demands
are considered:
- Anchor distance: 13-15 m /
42.6 - 49.2 ft
- Maximum mastheight above last anchor:
0.4 x anchor distance
- Loading during assembling:
Single: max. 750 kg / 1650 lb
+ 2 persons
Twin: max. 1500 kg / 3300 lb
+ 4 persons
- Maximum, windspeed during
assembling: 6 Beaufort (12,5 m/sec).
(41 ft/sec)
- Distance a (mast centre to facade):
0.9 -1.63 m / 35.4 - 64.2 in
- Distance b (between the anchor points
on the facade): min. 0.7 m / 27.6 in
- Ratio a/b: 0.8 - 2.0
The anchorforces of the MSHF up to 100 meters are given in the undermentioned table.
Above 100 meters the anchor forces will be 20 % higher than the anchor forces in the
given table.
