DESCRIPTION/PURPOSE:
The DBI-SALA Concrete Detent Anchor is composed of a cap (A), label (B), detent pin (C), and a socket (D). See
Figure 1. The connector is designed for use as a component of a personal fall arrest system (PFAS). PFASs are used where a free fall is pos-
sible, before the fall is arrested, and typically including a self retracting lifeline to EN 360 or an energy absorbing lanyard to EN 355, connector
to attach to the anchor to EN362 and a full body harness to EN 361.
IMPORTANT:
Before using this equipment, record the product identi
fi
cation information from the ID label into the Equipment
Identi
fi
cation Sheet at the back of the GIUM.
REQUIREMENTS:
Installation and use of this equipment is restricted by the following limitations:
•
Capacity:
One person. Note: For emergency rescues it may be acceptable to connect more than one system if the anchorage will
support the anticipated loads.
•
Maximum Arresting Force:
PFAS used with this equipment must meet applicable EU CE requirements. The PFAS must be capable of
arresting the user’s fall with a maximum arresting force of 6kN.
WARNING:
Mark or label the detent anchor with the intended application. Use of this equipment for an application that does not meet the
anchorage strength requirement stated above may result in serious injury or death.
•
Making Connections:
When using a hook to connect to the detent anchor, ensure roll-out cannot occur. Connecting hardware must be a
carabiner or a 16 kN (3,600 lb.) self-locking snap hook.
INSTALLATION/USE:
Plan your system. Consider all factors that will affect your safety during use of this equipment.
•
Detent Anchor Location:
Select a location on a suitable strength anchorage that will provide overall safety and proper loading as
shown in Figure 2. The concrete must have a minimum compressive strength of 20.7 MPa. The detent anchor is not intended for use in
lightweight concrete, hollow block, brick, grout, or stone, wood, or other substrate. The concrete base material must be at least 19 cm
thick (F). See Figure 3. Do not use near cracks in concrete.
The mounting hole for the detent anchor must be located at least 20.3 cm from any free edge (C and D) and far enough away from any
obstruction or feature that will keep the D-ring from rotating freely when a personal fall arrest system is attached to it. When mounting
more than one detent anchor, they must be separated by at least 25.4 cm (B and E). Drill bits used to create the mounting holes must
conform to CE requirements. See Figure 3.
IMPORTANT:
The socket will be permanently set into the concrete. It can not be removed.
IMPORTANT:
This anchor must only be used with DBI-SALA sockets. Do not put anything in the socket other than DBI detent anchor or cap.
IMPORTANT:
When used in conjunction with the anchor, the adhesive used should be able to withstand a force of 10kN (2250lbs) in all
directions of loading.
•
Installation steps:
Step 1.
Use a rotary hammer and a 22mm (A) rotary hammer drill bit to drill a hole to a depth of 10.5 cm (G). (Figure 3.)
Step 2.
Clean the hole using a blow-out bulb or compressed air. Next use a hole brush to remove loose particles. Again clean the hole
out using a blow-out bulb or compressed air.
Step 3.
Inject the adhesive in the hole according to the adhesive’s instructions. Fill the hole 1/3 to 1/2 full.
Step 4.
Use a M6 allen wrench and insert it into the socket. Use the wrench to slowly thread the socket into the hole and down into the
adhesive. Continue threading the socket into the adhesive until the top of the socket is 1.6 mm above the concrete surface.
Remove excess adhesive that may have protruded from the hole. Do not touch. Allow time for the adhesive to set and cure
according to the adhesive’s instructions.
Step 5.
Once the adhesive has had time to set and cure, press the detent button (A) and insert the detent anchor (B) into the socket
hole (C). Pull on the detent to make sure it is locked in the socket. (Figure 4.)
•
Removal:
The detent pin (D) may be removed from the socket by pushing the detent button (A) and pulling the detent pin out. Insert
the plastic cap into the socket to keep contaminants out of the hole. The socket can not be removed. (Figure 4.)
•
Reuse:
Before reusing a socket, inspect the socket for signs of damage or wear. Also examine the concrete (E) around the socket for
signs of cracks or damage. See Figure 4. If inspection reveals an unsafe or defective condition, do not use the socket. To reuse any of
the sockets, remove the cap (Figure 1A) from the hole and insert the detent pin into the socket.
INSPECTION:
•
Frequency:
Before each use, visually inspect per the inspection steps below.
•
Inspection Steps:
(See Figure 4)
Step 1.
Inspect the detent pin (D) and the socket for signs of damage or corrosion. Remove the detent pin and inspect for cracks or
wear that may affect the strength. The detent button (A) should work smoothly. Inspect the 4 locking balls (F) for signs of
damage. All 4 locking balls must fully extend and lock. If a locking ball is missing, remove the detent pin from service.
Step 2.
Inspect the detent anchor connector (B) for signs of damage. The detent should be able to rotate freely in the socket and the
detent ring should be able to rotate 180 degrees on the detent pin
Step 3.
Inspect the concrete (E) around the socket (C) for cracking and signs of damage that could affect the strength of the anchor.
Step 4.
Record the inspection results in the Periodic Examination and Repair History Log in the GIUM.
MAINTENANCE:
Clean the detent anchor with a mild soap solution. Excessive build-up of dirt may prevent the D-ring from swiveling and the
locking balls from locking in the socket.
TRANSPORT/STORAGE:
Transport and store the detent anchor in a cool, dry, clean environment. Thoroughly inspect the detent anchor after
extended storage or transport.
