PORTA
GANTRY
500-3000
Intended Use
This product is intended to be used for the lifting of
goods, the lifting of personnel, rope access or for
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
This 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 assembly of the product
and all load-bearing components should be
checked for visual defects. This includes checking
the integrity of all profiles for denting, making sure
there is no wear or elongation on the bolt holes
and ensuring that the trolley moves freely along
the beam.
Correct Operation
Only raise and lower loads when castor brakes
are engaged
Do not allow the load to swing
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 on the trolley.
(Refer to figure A)
We recommend the use of load-sensing or
overload protection devices on all lifts
The risk assessment and method statement
must take into account any factors that might
apply additional loading to the system during
lifting operations
Take care when transporting and storing the
system to avoid damage
To ensure stability of the structure, the
operating span of the beam must be equal
to or greater than the distance between the
castors on the A-Frame.
Warning
The equipment should not be used outside
of its limitations, or for any purpose other than
that for which it is intended
Do not lift or transport loads while personnel
are in the danger zone
Do not allow personnel to pass under a
suspended load
Never leave a suspended load unattended
Do not start moving the load along the beam
until you have checked that it has been
attached correctly
Don’t allow the load to hit the system frame
When winching, only use one winch with each
sheave and make sure they never cross paths
with each other
Be aware of any adverse weather conditions
such as strong or gusty winds which could
impose additional horizontal loads and affect
the stability of the structure. Stop using if
weather is impacting on lifting, and either
disassemble the gantry or tie it to a rigid
structure to ensure it can’t overturn
Be aware of hazards when setting up/folding
down, such as trapping fingers in rotating
parts
Traversing the Load
Due to a high modulus of elasticity in aluminium,
when loaded the gantry beams will deflect.
This is perfectly normal for our products. Using
aluminium enables us to achieve the highest
levels of strength to weight ratio, which is an
important feature of portable gantries. The level of
deflection will be determined by the span length
and the beam profile that is being used, as well as
the weight of the load being lifted.
Before traversing loads on the
PORTA
GANTRY, it
is important to take in to account the following;
Only use appropriate REID trolleys to move the
load on the beam.
When moving a loaded trolley along the
beam, move the load steadily and in a
controlled manner. Do not apply an excessive
force to try and move the load if it does not
move easily.
Depending upon the beam section (A, B or
D), beams will deflect when loaded.
This is
normal.
The greater the load, the greater the
deflection. Please refer to our beam deflection
table for more information. Deflection must be
taken into consideration when planning the lift.
Any traversing of loads along the beam must
be performed in a controlled manner to ensure
complete stability of the structure throughout
the operation.
Maximum Capacity
Goods Lifting:
This product is designed to lift
and lower loads up to its rated capacity. Do not
exceed the working load limit 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 this product also needs to be
considered.
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.
Notes for Correct Operation
Assemble only as instructed (ensure all
bolts are present and fitted correctly as per
instructions)
Suitable, appropriately rated winches and
connection plates must be used for all
applications
The product should be set up at a safe
distance from the hazard or lift area, before
moving the structure into place
The supporting ground/structure where
the gantry is to be used must be stable
and capable of withstanding the maximum
expected load applied during use
We recommend that gloves are worn when
using the equipment
The beam must be horizontal prior to any lift
and A-Frames vertical and parallel to each
other
Do not use the product if the trolley does
not run freely along the beam. (For certain
applications, such as when the system is being
used as a restraint point, the trolleys can be
locked into position)
Attach the hoist to the lifting point on the
trolley only, making sure it is attached in a way
that does not expose the user to danger by
the hoist, chain or load
