Parameters affecting the mechanical and electronic performance of each hoist include:

1. Load division
the magnitude of the load in relative to the nominal load of the hoist according to the cube law mentioned will determines the life span of the parts. For example, with a two-ton hoist , the life span of the bearings will be increased  eight times if the one ton load is used on the hoist

2. Working time

3. Division of labor
Concentrated work greatly shortens the life of the crane.
For example, the life of a heavy duty machine with a 2M workgroup is rapidly reduced if one hour of concentrated work is done compared to, for example, to a 15 minutes work per hour.
Of course, this rapid reduce of life is mainly on electrical components such as motors and switches, due to the heat exerted on them.

4. Number of Starters – Stops
It directly affects all mechanical power tools such as motors, brakes, etc.

5. Environmental conditions
these conditions are: high temperatures, dust, humidity, corrosive materials and…
