Hoist Capacity Calculator
Static · formula-only · worked example computed when this page was built · no live data
The Hoist Capacity Calculator finds the gross load, motor power, and safety margin for a lifting duty. Example: for a 2000 kg lift at 8 m/min on a 2-part rope line, with a 30 kg hook, Gross load = 2045 kg, Motor = 7.5 HP, Motor power = 5.59 kW (per ASME B30.2).
How it works
Computed from your inputs per ASME B30.2. Anything the worked example does not state uses this calculator's standard default; the interactive version shows every input and lets you change it.
Worked example (Vertical Transport)
Inputs: a 2000 kg lift at 8 m/min on a 2-part rope line, with a 30 kg hook.
| Result | Value |
|---|---|
| Gross load | 2045 kg |
| Motor | 7.5 HP |
| Motor power | 5.59 kW |
Computed by WorkHive's calculation engine when this page was built; standard: ASME B30.2.
How to use this calculator
- Read the worked example. It uses a 2000 kg lift at 8 m/min on a 2-part rope line, with a 30 kg hook and shows every number in the method.
- Follow the formula with your own figures: it returns Gross load, Motor, Motor power, computed per ASME B30.2.
- To compute interactively, open the Hoist Capacity Calculator inside WorkHive's free Engineering Design suite (link below). It runs the same method with your inputs.
FAQ
What is a hoist crane capacity calculator?
The Hoist Capacity Calculator is a free online tool that finds the gross load, motor power, and safety margin for a lifting duty. It shows the formula and a fully worked example so you can check the method, not just the number.
How is it calculated?
The result is computed from your inputs following ASME B30.2. The worked example on this page shows a real computation with real numbers.
Is the calculator free?
Yes. WorkHive is free: this worked example is open to everyone, and the interactive calculator runs inside the free Engineering Design suite after a free sign-up (your work is saved to your account). WorkHive is a free, offline-first maintenance platform built for Philippine industrial plants.
