Temperature Range
This product can be operated in ambient dry
temperatures between –20°C and +55°C (-4°F
and 131°F). Consult your supplier in case of
extreme working conditions. If used in sub-
zero and wet conditions, fall arrest appliances
characteristics may change.
Notes for Correct Operation
For winched variants, each of the product’s
three sheaves have been designed to work
specifically with the rope materials and
diameters detailed below:
It is important to ensure that the correct
sheave is being used to prevent pinching or
squashing of the rope
We recommend the use of load-sensing or
overload protection devices on all lifts
The risk assessment and method statement
must consider any factors that might apply
additional loading to the system during lifting
operations
Suitable, appropriately rated winches and
connection plates must be used for all
applications
Take care when transporting and storing the
system to avoid damage
Assemble only as instructed (ensure all
bolts are present and fitted correctly as per
instructions
We recommend that gloves are worn when
using the equipment
Attach the hoist to the dedicated lifting point
only, making sure it is attached in a way that
does not expose the user to danger by the
hoist, chain or load
Do not allow the load to swing
Only attach the load to the lifting points on the
head or winch line
Contact your supplier before using the davit
in (special atmospheres) extreme conditions
To avoid side pull, lowering and lifting should
only be carried out when the load chain forms
a straight and vertical line between the load
and lifting attachment point. (Refer to figure A)
Do not assemble the davit in any non-
approved socket
Make sure that the kingpin shaft is correctly
seated in the socket before use
Do not use this product if it does not rotate
freely in the bearing or if the bottom flange
is fouled in any way that prevents that free
rotation
Do not knot or shorten the tension strap to
reduce the operating radius
Always ensure that the product is set up in
its mounting socket in a safe location where
there is no risk of falling into the hazard or lift
area
Intended Use
This product is intended to be used for; the lifting
of goods, the lifting of personnel, rope access, or
providing a safety anchor for the prevention of falls.
It is expected that all users of this product have the
necessary medical and physical capabilities, are fully
trained and competent in its safe assembly and use.
Inspection Prior to Initial Operation
Each product must be inspected prior to initial
operation by a competent person to ensure that the
structure is safe and that it has not been damaged
by incorrect assembly, transport or storage.
Inspection Before Starting Work
Before starting work, the product assembly and
all load-bearing components should be checked
for visual defects as per the inspection checklist on
page 8.
Correct Operation
Maximum Capacity
Goods Lifting:
This product is designed to lift
and lower loads up to its rated capacity. Do not
exceed the capacity indicated on the product.
Personnel Lifting:
When lifting people, the
overall load limit is reduced by half to provide an
increased safety factor. The maximum capacity
permitted by the personnel winch/accessory used
in conjunction with the product also needs to be
taken into account.
Only chain hoists with a capacity of up to 1000kg
are suitable for this davit. The structure has been
designed to take into account the weight of
a standard chain block but, if a device with a
significant additional weight is being used, then
this needs to be included within the overall
capacity. Care should also be taken when using
any lifting device other than a manual chain
hoist in case the dynamic effects of this reduce
the overall capacity of the davit. REID Lifting’s
representatives can provide additional advice on
this if required.
The table below gives the maximum WLL and
radius for each of the standard models.
Please be aware that the maximum radius
is achieved when the davit is being used at
approximately 75% of its maximum capacity.
