Hydraulic Cylinder Test Load with test-stand connected load of 30 kW: a worked example

This scenario runs the hydraulic cylinder test load calculation on the strong side: test-stand connected load of 30 kW, with every other input held at its documented default. Use it when hydraulic cylinder test load in mining vehicle and underground equipment is being quoted and energy is a real chunk of the mining vehicle and underground equipment cost stack.

The inputs for this scenario

  • Test-stand connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Cylinder test runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Cylinders tested during runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total hydraulic cylinder test load energy cost = hydraulic cylinder test load connected load × hydraulic cylinder test load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for hydraulic cylinder test load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total hydraulic cylinder test load energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly hydraulic cylinder test load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where test-stand connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • Use it when costing a rebuild or test operation, sizing a test bay's energy budget, or comparing the running cost of two test stands. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Hydraulic cylinder test load energy used: 240 kWh (headline result)
