REID’s davits need to be anchored to a suitable
structural surface/foundation capable of
withstanding the applicable loading We strongly
recommends that a structural engineer validates
this prior to installation of the product.
This product can be supplied with one of the
sockets specified below (only sockets supplied
by REID Lifting are approved to be used with this
product):
The Top Mount socket is for use on flat
horizontal surfaces. It can be installed onto
concrete using resin bonded anchors or into
steel work using bolts
The Side Mount socket can be installed using
resin bonded anchors or mechanical anchors
The Bridge Mount socket is for mounting into
steel work and walkways
The Cast & Resin Bonded sockets can be
cast into new concrete or resin bonded into
existing concrete
Socket Installation
Socket installation should only be carried out by
a qualified person, with the ability to specify the
anchors, resin, and fasteners necessary to ensure
an installation that is safe for use. If in any doubt
about the calculation of loads, contact your REID
Lifting representative.
Depending upon the socket type, there are a
number of different installation options. If bolts
are being used for this, then these should be
minimum grade 8.8 BZP or if stainless, grade A4
or equivalent.
When installing the socket, it is important to
ensure that the top face is as level as possible,
with misalignment no more than 3 degrees from
the horizontal.
Note: Site specific information regarding the
installation of REID davit sockets CANNOT be
detailed within this operating manual as each
site/structure is different. A qualified engineer
MUST design and approve each installation
based on the minimum mounting requirements,
site information and experience.
Minimum Mounting Requirements
The supporting structure and installed base must
be capable of withstanding the following:
For personnel, 12kN at the device’s maximum
radius in all worst-case loading directions.
For rope access, 15kN at the device’s maximum
radius in all worst-case loading directions.
150% of the goods capacity at the device’s
maximum radius in all anticipated worst-case
loading directions
For more detailed requirements please contact
REID Lifting.
Verifying the Installation
We recommend that the socket installation is
tested before initial use, particularly when using
resin bonded anchors. When verifying the
installation, testing should be to no more than
125% of the goods capacity at its maximum radius
or 6kN at its maximum radius for personnel. All
tests should be carried out in all anticipated
worst-case loading directions, sustained for a
duration of 3 minutes.
If the socket installation can’t be tested, each
anchor should be isolated and tested individually
applying the applicable tension and shear
loading. Please contact REID for more details
Following initial socket installation verification
tests, we recommend periodic visual examination
rather than overload tests for the socket or davit.
If, as a result of the visual examination, a load test
is judged to be required, then we recommend a
100% load test and certainly no more than 125%.
