D/E 003 Double Ended Roof Anchor
Design
The Safetor D/E 003 Height Safety Anchor is designed to be installed where two roof planes falling in different directions do not share a common ridge and may be separated by a wall causing a step.
One end of the Anchor protrudes up through the higher roof plane while the other protrudes down through the soffit. Some building owners may require an anchor point inside the buildings over equipment for maintenance and also outside for roof maintenance, this anchor point covers both. The D/E 003 anchor is designed to be bolted to both timber or steel structures and different configurations may be required. We can provide these if needed.
This anchor can be used for fall-arrest, abseiling, and as an end anchor for lifelines. Manufactured from a 30mm Mild Steel bar and can be suited for any height and configuration. One or two mounting plates can be fitted to the shaft, which is manufactured from a 4mm Mild Steel plate, with 3 x 18mm holes per plate on either side of the main shaft for ease of adjustment.
Each anchor comes with 4mm backing plates to match the mounting plate.
Standards:
All exposed Safetor anchors meet the requirements of the following standards:
- AS/NZS 5532.2013 : Manufacturing requirements for single anchor point device use for harness based work at height;
- AS/NZS 1891.2:2001 : Horizontal Lifeline and Rail Systems;
- AS/NZS 1891.4:2009 : Industrial Fall Arrest Systems and Devices;
- AS/NZS 1891.4:200 Standards: Strength Requirements for anchorages.
Ultimate Strength
- End anchor for horizontal lifeline – 44kN
- 1 Person – Free Fall Arrest – 15kN
- 2 Person – Free Fall Arrest – 21kN
- 1 Person – Limited Free Fall Arrest – 12kN
NB
1. Anchorage strength applicable when using restraint technique, is either 15kN or 12kN depending on whether the ultimate fall is free-fall or limited free-fall.
2.’Ultimate Strength’ means that the anchorage may yield at the stated load but must not fail.
Bolts
Bolts used to attach the anchors are M16mm Construction Bolts. The number of bolts used to attach the anchor to the structure can be 2 to 4 sets of bolts. All the timber testing to date on 4 x 2 framing has been using 2 x sets of bolts
NB:
The only time we recommend the use of 4 bolts is when the anchors are attached to C-Section light gauge steel purlins.
Bracing System
The D/E 003 has a two piece bracing plate which is attached using the mounting plate bolts. This plate allows for bracing to be bolted between the anchor and a bracket on the purlin below for a more solid connection. (see details)
NB:
As there are a number of different sizes of purlins we do not supply the galvanized purlin brackets these can be obtained from the purlin manufacturer.
Blasting
Profile blasted to remove all scale and grease etc.
Coatings
Plascoat PPA 571 ES is resistant to stress cracking, adverse weather conditions, detergents, salt spray and typical airborne pollutants. The coating maintains excellent adhesion to the metal substrate without the need for a separate primer. The material also provides good abrasion and impact resistance.
Installation
The installation should only to be carried out by a competent person as set out in the AS/NZS 1891.4:2009 Standards. Collins Corporation Ltd. provide a warranty on product performance of the anchor and not the structure. It is the responsibility of the installer, building designer, or building owner to ensure that the structure to which the anchor is attached to will support a load of at least 15kN as set out in the AS/NZS 1891.4:2009 Standards. If there is any doubt about the structures adequacy, a structural engineer should be consulted.
