Hoist Motor Load with hoist motor connected load of 6 kW: a worked example

Suppose hoist motor connected load falls to 6 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate hoist motor load for port, crane and terminal equipment using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • Hoist motor connected load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Hoist duty runtime per shift: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Containers or lifts handled during runtime: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total hoist motor load energy cost = hoist motor load connected load × hoist motor load runtime × blended electricity rate.
  • Hoist motor load energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total hoist motor load energy cost works out to 5.76 $ at these inputs.
  • Energy cost per kWh works out to 0.01 $ / piece at these inputs.
  • Hourly hoist motor load energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where hoist motor connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • It multiplies hoist connected load by runtime to get kWh, applies the electricity rate for total cost, then divides by units handled for cost per lift. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
