Surface Mounted Anchor
ANCHOR DEVICE: Topfix Surface Mounted Anchor (SMA)
To be used as a tethering anchor only
TWO FIX SYSTEM : BONDED AND RIVETED
ANCHOR TYPES AND CAPABILITIES
FINISH: 316 Stainless Steel.
ULTIMATE YIELD TESTING:
We tested using brand new corrugated galvanised iron 15kN on .40gage roofing iron & 21kN on .55gage roofing iron. The tested attachment was no greater than 5mm from the surface of the roofing iron.
The load testing carried out by MTL, have shown that this type of anchor will not sustain the loading required set out in the standard for fall arrest and to use this type of anchor for fall arrest could cause serous harm or even death to the user.
All types of topfix anchors riverted to the surface of roofing iron in NZ or AU DO NOT
comply to the AS/NZS 1891.4 standards.
AS/NZS 1891.4
Section 3.1.2 (a)
The anchorage and the structure to which it is attached shell be capable of sustaining an ultimate load to that shown in Table 3.1
(15kN = 37.5bags of cement & 21kN = 52.5bags of cement)
Thin tensile steel roofing can not sustain the loading for fall arrest as our destructive tests have shown.
AS/NZS 1891.4:2000
Section 3
Table 3.1
1 persons - Free fall arrest 15kN
2 persons - Free fall arrest 21kN
1 person - Restrained fall arrest 12kN
Note: Total restraint has been removed
from the AS/NZS 1891.4 standards.
Part 4:
Section 1.2 (a)
Any person at risk of a potentially
injury producing fall shell be secured by equipment that is rated for fall arrest.

CCL surface mounted anchors are not only attached to the roofing by rivets like all other top fix systems, CCL have gone the extra mile to ensure a much stronger attachment point by bonding and riveting the anchors to the roofing  |
