- No user shall use or permit the use of a lifting machine unless
(a) it has been designed and constructed in accordance with a generally accepted technical standard;
(As amended by Par. 3(a) of G.N.R. 2483 dd.4/9/1992)
(b) it is conspicuously and clearly marked with the maximum mass load which it is designed to carry
with safety; Provided that when this mass load varies with the conditions of use a table showing the
maximum mass load with respect to every variable condition shall be posted up by the user in a
conspicuous place easily visible to the operator, and
(As amended by Par. 3(b) of G.N.R. 2483 dd.4/9/1992)
(c) it has at all times at least three full turns of rope on the drum of each winch which forms part of such
a machine when such a winch has been run to its lowest limit.
(As inserted by Par. 3(c) of G.N.R. 2483 dd.4/9/1992)
- The user shall, where practicable, provide every power driven lifting machine with -
(a) a brake or other device capable of holding the maximum mass load should the power supply fail,
or which is such that it will automatically prevent the uncontrolled downward movement of the load
when the raising effort is interrupted; and
(b) a limiting device which will automatically arrest the driving effort when -
(i) the hook or load attachment point of the power-driven lifting machine reaches its highest safe
position; and
(ii) in the case of a winch-operated lifting machine with a lifting capacity of 5000 kg or more, the
load is greater than the rated mass load of such a machine.
(As substituted by Par. 3(d) of G.N.R. 2483 dd.4/9/1992)
- The user shall cause every chain or rope which forms an integral part of a lifting machine to have a factor
of safety as prescribed by the standard to which such machine was manufactured: Provided that in the
absence of such prescribed factor of safety, chains, steel wire ropes and fibre ropes shall have a factor
of safety of at least four, five and ten respectively, with respect to the rated carrying capacity of the lifting
machine.
- The user shall cause every hook or any other load attaching device which forms an integral part of a lifting
machine to be so designed or proportioned that accidental disconnection of the load under working conditions
cannot take place.
- The user shall cause the whole installation and all working parts of every lifting machine to be thoroughly
examined and subjected to a performance test, as prescribed by the standard to which the lifting machine
was manufactured, by a person who has knowledge and experience of the erection and maintenance of
the type of lifting machine involved or similar machinery and who shall determine the serviceability of the
structures, ropes, machinery and safety devices, before they are put into use following every time they
are dismantled and re-erected, and thereafter at intervals not exceeding 12 months: Provided that in the
absence of such prescribed performance test the whole installation of the lifting machine shall be tested
with 110 per cent of the rated mass load, applied over the complete lifting range of such machine and in
such a manner that every part of the installation is stressed accordingly.
(As amended by Par. 3(e) of G.N.R. 2483 dd.4/9/1992)
- Notwithstanding the provision of subregulation (5), the user shall cause all ropes, chains, hooks or other
attaching devices, sheaves, brakes and safety devices forming an integral part of a lifting machine to
be thoroughly examined by a person contemplated in subregulation (5) at intervals not exceeding six
months.
- Every user of a lifting machine shall at all times keep on his premises a register in which he shall record
or cause to be recorded full particulars of any performance test and examination prescribed by subregulations
(5) and (6) and any modification or repair to the lifting machine, and shall ensure that the
register is available on request for inspection by an inspector.
(As substituted by Par. 3(f) of G.N.R. 2483 dd.4/9/1992)
- No user of machinery shall require or permit any person to be moved or supported by means of a lifting
machine, unless such machine is fitted with a cradle approved for that purpose by an inspector.
(As substituted by Par. 3(g) of G.N.R. 2483 dd.4/9/1992)
- No user shall use or permit any person to use a jib crane with a lifting capacity of 5000kg or more at a
minimum jib radius, unless it is provided with -
(a) a load indicator which will indicate to the operator of the jib crane the mass of the load being lifted:
Provided that such advice shall not require manual adjustment, from application of the load to the
jib crane until the release of that load, using any motion or combination of motions permitted by the
crane manufacturer to ensure safe lifting; or
(b) a limiting device which will automatically arrest the driving effort whenever the load being lifted
is greater than the rated mass load of the jib crane, at the particular radius, using any motion or
combination of motions permitted by the crane manufacturer to ensure safe lifting: Provided that
such a device shall not arrest the driving effort when the jib-crane is being operated into a safer
condition.
(As substituted by Par. 3(h) of G.N.R. 2483 dd.4/9/1992)
- No user shall use or allow the use of any lifting tackle unless the following conditions are complied
with, namely that -
(a) every item of lifting tackle is well constructed of sound material, is strong enough and is free
from patent defects and is in general constructed in accordance with a generally accepted
technical standard;
(b) every lifting assembly consisting of different items of lifting tackle is conspicuously and
clearly marked with identification particulars and the maximum mass load which it is
designed to lift with safety;
(c) ropes of chains have a factor of safety with respect to the maximum mass load they are
designed to lift with safety of –
(i) ten for natural-fibre ropes;
(ii) six for man-made fibre ropes or woven webbing;
(iii) six for steel wire-rope except for double part spliced endless sling legs and double part
endless grommet sling legs made from steel wire rope, in which the factor of safety shall
be at least eight;
(iv) five for steel chains; and
(v) four for high tensile or alloy steel chains: Provided that when the load is equally shared
by two or more ropes or chains the factor of safety may be calculated in accordance with
the sum of the breaking strengths taking into consideration the angle of loading;
(d) steel-wire ropes are discarded and not used again for lifting purposes if the rope shows signs
of excessive wear, too many broken wires, corrosion or other defects that have made its use
in any way dangerous;
(e) such lifting tackle is examined at intervals not exceeding three months by a person contemplated
in subregulation (5) who shall enter and sign the result of each such inspection in
a book kept for this purpose; and
(f) such lifting tackle is stored or protected so as to prevent damage or deterioration when not
in use.
- The user shall ensure that every lifting machine is operated by an operator specifically trained for a
particular type of lifting machine; Provided that in the case of lift trucks with a lifting capacity of 750 kg or
more and jib-cranes with a lifting capacity of 5000 kg or more at minimum jib-radius, the user shall not
require or permit any person to operate such a lifting machine unless the operator is in possession of a certificate
of training, issued by a person or organisation approved for this purpose by the Chief Inspector.
