NOTE: The receiving structure must be able to withstand
stresses equivalent to 22.1 MPa or 22.1N/mm2. The
fasteners/structural anchors must be strong enough to handle this
strain. They must be stainless steel/High tensile, size M16.
ŸThickness of concrete block should be minimum
9"(228.6mm)
ŸDrill hole should have a minimum clearance of 11"(279.4mm)
from all the available edges
ŸAll receiving Structure should be verified by a qualified
structural Engineer.
ŸCan be installed on cantilever of concrete beam by
sandwiching two plates on beam & concrete structure should
be verified by a qualified structural Engineer.
ŸSuitable M16 fasteners should be used for fixing the brackets
to the structure.
ŸFor dismantling the product, go through the described steps
in reverse order.
ŸBase Installation must be approved to local regulations by a
qualified engineer.
ŸRefer to Fastener Manufacturer to ensure the correct
fasteners are used.
ŸIf the Base material does not meet the minimum requires to
install, then reinforcement is required. Refer to a qualified
engineer.

INSTALLATION:
Davit Flush Mounting sleeve can be installed at time of concrete structure being made & also can be installed in preformed concrete casting. To
install the sleeve on preformed surface, make a drill hole of 112 mm dia. up to 274 mm deep. Also ensure to remove all the debris from hole & clean
it properly, after that, Use all weather 400 epoxy or equivalent into hole to fix the sleeve.
Installation of mounting sleeve can be done during casting of the concrete by considering below requirements & subject to the condition that
concrete should not ingress into the sleeve and sleeve should be properly flushed -
Structure strength- 14000 NM(Min.)
Thickness of concrete & distance from sleeve to edge should be duly checked & approved by a qualified structural engineer.
Installation of sleeve should be perpendicular to the concrete.
Repeat Step 9-14 to install brackets for winch and Rescue Retrieval SRL (Type 3)
Note- When flushed sleeve is not in use, apply socialized cap provided with assembly to prevent it from unwanted water/dust being stuck inside.
Make the Allen screw loose with help of 6.0 mm Allen key for the opening of sleeve & when sleeve is not in use, insert the cap into sleeve and tighten
the screw with help of 6.0mm allen key. Base Installation must be approved to local regulations by a qualified engineer.
