HOISTING
GEAR
Usually admitted gear:
• Hoisting gear interposing themselves between the lifting hook and the load, such as for example:
clamps, horizontal lifting bars, suckers, magnets, etc.
• Slings made with ropes and/or chains and/or textile or plastic bands.
• Lifting gear must be used according to the instructions provided by their manufacturers.
Usually not admitted gear:
• Gear fed by independent electric lines
• Gear that, during operations, may collide with parts of the lifting machine.
• Gear limiting load handling.
• Gear whose functional characteristics may induce dynamic overstress exceeding acceptable limits or accidental overload..
MACHINE USE AND SAFETY MEASURES
To obtain the best performance from the machine, it is recommended to use it observing the following instructions:
• ALWAYS follow the rules given in the operation and maintenance manual.
• ALWAYS take heed of the rules and warnings written on the machine. Warning plates on the machines are safety notices
and must be perfectly readable at all times.
• ALWAYS stop using the machine if any of the following occurs: machine not working properly, a suspicion that something is
broken, incorrect movements, unusual noises, or any other unusual detectable fault.
• ALWAYS follow the maintenance schedule with great care and record, for each check, any observations with regard to, in
particular, hooks, wire ropes, brakes, limit switches and load limiter.
• ALWAYS keep the brakes, limit switches, load limiter and all other safety devices under constant check.
• ALWAYS check periodically the degree of wear and tear and of efficiency of wire ropes and hooks (see the relevant
paragraphs).
• ALWAYS make sure that slings are well fastened to the hook and pull them tight carefully and slowly, prior to lifting the load.
• ALWAYS use of the machine only after its full efficiency has been assessed and allow its use to specifically trained staff
only.
• ALWAYS all machinery, big or small, indoors or outdoors, while not in operation, must never be left unattended unless all
safety measures have been implemented.
• ALWAYS check the “emergency stop” push button works properly.
• ALWAYS make sure the machine operates in a duly protected from atmospheric agents (rain, wind, snow, etc.) environment
or, if located outdoors, that it has suitable protections.
• ALWAYS make sure movements correspond to the relevant controls.
• ALWAYS warn all people at risk that handling operations are about to start.
• ALWAYS check the machine and its main components (the push button control pendant, for example) are suitably
maintained properly maintained (cleaning, lubrication).
• ALWAYS verify the machine’s performance is suitable to the service it is intended for.
• ALWAYS verify the fitness and functioning of the electrical control panel and the correct functioning of motors in particular.
• ALWAYS verify the fitness and efficiency of the sling (chains, straps, ropes, etc.) checking there are no patent damages
such as deformations, tears etc.
• ALWAYS make sure the machine’s hook is centered with respect to the perpendicular prior to slinging and handling the
load.
• ALWAYS work outside the operating range of the hoisted load.
• ALWAYS work in the best possible conditions as to lighting and visibility of the load and of the relevant operating area.
• ALWAYS use “slow” speeds for approaching and lowering operations.
• ALWAYS avoid using combined movements and swinging the load.
• ALWAYS report any anomalies such as failures, suspected breakages, incorrect movements, excessive noisiness etc., to
the competent person in charge and discontinue use of the machine.
• ALWAYS switch-off power supply to the machine in the event of maintenance, inspections or repairs and when done with
using the machine.
• ALWAYS make sure the load meets no obstacles during handling operations.
• ALWAYS, when the work is finished, bring the machine to a “parking” position with regard to ropes, hooks and push button
control pendants so that they are not at risk of collision.
• ALWAYS wear suitable working clothes and, if necessary, personal protective equipment.
