Hoists and Lifts
Safeguard measures with regard to the hoists and lifts. These are discussed below:
Good quality and proper maintenance:
In every factory every hoist and lift shall be of good Mechanical construction, sound material and adequate strength. They shall be properly maintained, and thoroughly examined by a competent person at least once in every period of six the prescribed particulars of every months Further, a register such examination shall be kept- containing.
Protection of the hoist way and lift way:
Every hoist way and lift way shall be sufficiently protected by an enclosure fitted with gates. The hoist or lift and every such enclosure shall be so constructed as to prevent any person or thing from being trapped between any part of the hoist of- lift and any fixed structure or moving part.
Marking of load:
The maximum safe working load shall be plainly marked on every hoist or lift, and no load greater than such load shall be carried thereon.
Gate and its safety
The cage of every hoist or lift used for carrying persons shall fitted with a gate on each side from which access afforded to a landing. Moreover, every gate shall be fitted with inter looking or other efficient device to secure that the gate cannot be .opened except when the cage is at the landing and that the cage cannot be moved unless the gate is closed.
Additional safety measures:
The following additional measures shall taken in case the hoists and lifts have installed or reconstructed after commencement of this Act:
Where the cage supported by rope or chain, there shall at least two ropes of chains separately connected with the cage and balance weight. Each rope or chain with its attachments shall capable of carrying the ~ whole weight of the cage together with its maximum load.
Efficient devices shall be provided and maintained capable of supporting the cage together with its maximum load in the event of breakage of the ropes, chains or attachments. An efficient automatic device shall provided and maintained to prevent the cage from over-running.
Permission to use the existing hoists and lifts:
The Chief Inspector may permit the continued commencement of this upon such conditions for ensuring safety as he may think fit to impose.
The State Government may, if in respect of any class or description of hoist or lift, it is of opinion that it would be unreasonable to enforce any of the above requirements; by order direct that such requirement shall not apply to such class or description of hoist or lift.
Lifting Machines, Chains, Ropes and Lifting Tackles:
Section 29 of factories act provides safety measures with regard to lifting machine like hoist and lift, chains and lifting tackles for the purpose of raising or lowering persons or material or goods.
All parts, including the working gear, whether fixed or movable, of every lifting machine and every chain, rope or lifting tackle shall be: Of good construction, sound material and adequate strength and free from defects; Properly maintained and
Thoroughly examined by a competent person at least once in every period of 12 months or at such intervals as the Chief Inspector may specify in writing. A register shall also kept containing the prescribed particulars of every such examination.
A lifting machine or a chain, rope etc. shall be deemed to have been thoroughly examined if a visual examination supplemented, if necessary, by other means and by the dismantling of parts of the gear, has beer} carried out as carefully as the conditions permit in order to arrive at a reliable conclusion as to the safety of the parts examined.
Marking of load on Hoists and Lifts :
No lifting machine and no chain, rope of lifting tackle shall; except for the purpose of test, loaded beyond the safe working load. Working load shall plainly marked on them together with an identification mark; and duly entered in the prescribed register. Where this is not practicable; a table showing the safe working loads of every kind and size of lifting machine or chain; rope or lifting tackle in use shall be displayed in prominent positions on the premises.
Approach of the crane:
While any person employed or working on or near the wheel track of a travelling crane in any place where he would liable to be struck by the crane. Effective measures shall taken to ensure that the crane not approach within six meters of that place.
Power of the Government on Hoists and Lifts :
The State Government may make rules in respect of any lifting machine or any chain; rope or lifting tackle used in factories. The rules may provide for the following.
Further requirements to complied with in addition to those set out in this Section.
For exemption from compliance with all or any of the requirements of this Section; wherein its opinion, such compliance is unnecessary or impracticable.
It should noted that lifting machine means a crane, crab, winch, eagle, pulley block, girl wheel, transporter or runway. Again, lifting tackle means any chain sling, rope sling, hook, shackle, swivel, coupling, socket, clamp, tray or similar appliance. Whether fixed or movable, used in connection; ‘with the raising or lowering of persons, or loads by use of lifting machines.
Section 30of factories act provides measures of safety with regard to revolving machinery. These are as under:
Notice of safe working speed of grindstone or abrasive wheel:-
In every factory in which the process of grinding carried on; there shall permanently affixed to or placed near each machine in use a notice indicating the following:
- The maximum safe working peripheral speed of grindstone or abrasive wheel.
- Speed of the shaft or spindle upon which the wheel mounted.
- The diameter of the pulley upon such shaft or spindle necessary to secure such safe working peripheral speed.
Measures for not to exceed the speed of Hoists and Lifts :-
The speeds indicated in the above stated notices shall not exceeded. Effective measures shall taken in every factory; to ensure that the safe working peripheral speed of every revolving vessel; cage, basket, fly-wheel, pulley, disc or similar appliance driven by power not exceeded.
