Trades delivery weight batch grouping calculator

Calculate sequential lift loads and lift cycles with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use sequential lift loads and lift cycles to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Delivery item masses (kg)
200,150,80
User-approved payload per lift (kg)
250
Cycle time (minutes)
10
Sequential lift loads (JSON)
[200,230]
Lift cycles (count)
2
Total cycle time (minutes)
20

Try another scenario

Delivery item masses (kg)
[201, 150, 80]
User-approved payload per lift (kg)
250
Cycle time (minutes)
10
Sequential lift loads (JSON)
[201,230]
Lift cycles (count)
2
Total cycle time (minutes)
20
Calculation method

Calculation method

Sequential lift loads (JSON)

Next-fit loading in delivery order without splitting items; each item must fit the approved payload.

Lift cycles (count)

Next-fit loading in delivery order without splitting items; each item must fit the approved payload.

Total cycle time (minutes)

Next-fit loading in delivery order without splitting items; each item must fit the approved payload.

Symbols and units
a
Delivery item masses (kg)
b
User-approved payload per lift (kg)
c
Cycle time (minutes)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Supplied load grouping and time arithmetic; no crane selection, rigging, ground-bearing or lift safety approval. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
