Understand the working intensity of electric hoists

As a critical lifting component within crane systems, the performance and service life of an electric hoist depend not only on its lifting capacity and speed but also on its work duty (work classification) — a key parameter that must be considered during design and selection.

What is the Work Duty of an Electric Hoist?

The work duty of an electric hoist is typically defined according to FEM (European Federation of Materials Handling) or ISO standards. It reflects the hoist’s operational frequency, load conditions, and duration over a given period. Simply put, it indicates the hoist’s “durability level,” determining the environments and operational intensities under which the hoist can reliably perform.

Common Work Duty Classifications for Electric Hoists

Why Work Duty Matters for Electric Hoist Selection

1. Prolong Equipment Life
   Matching the correct work duty prevents premature wear or failure caused by overloading, significantly extending the hoist’s lifespan.

2. Ensure Safe Operation
   Different work duties require different motor power and braking systems to guarantee smooth and safe lifting operations.

3. Reduce Maintenance Costs
   Proper work duty specification lowers maintenance frequency and downtime, improving overall production efficiency.
