Lifting systems comprise all machinery and equipment that are needed for lifting loads. They are part of the handling equipment.
Their classification may be operated according to the way lifting force applies:
Lifting from below, for example by means of a forklift
Lifting from above, for example using slings
But also for elevator platforms, winches, hoists, articulated arms…
These lifting systems are present in all processing industries, notably for the transfer of pellets or powders. We can cite for example the food industry, textile industry, chemical and pharmaceutical industries.
The handling devices allow for the lifting of pellets or powders in order to reach a certain point and to empty it all into other containers.
These goods need to reach an exact position. The transfer from one container to another requires precision in the execution of the task. The operator needs to block the lift once the position has been reached and hold the equipment in this position.
These handling operations are often conducted using electrical appliances. These have proven effective but also show limitations.
In case of overheating of the electric motor for example, either because of a blockage (anomaly in the process), or because of a dusty atmosphere or an ambient temperature that is too high, there is a risk of fire as dust is flammable.
