Work it out.
Calculators for the forklift trade: find the load's centre of gravity, assess stability as a moment balance and interpolate the residual capacity on the load chart. Enter your own measurements — the result updates live.
Important
The calculators only illustrate the physical principles. The actual permitted load for a given load centre and lift height is ALWAYS read from the individual truck's own load chart (capacity plate).
Step A — Load & load centre
Find the load's centre of gravity: estimate the load centre from the length, combine several items into a single centre of gravity and see the residual capacity at a larger load centre.
Residual capacity at load centre
How much does capacity drop with a larger load centre?
Load centre from load length
Quick estimate of the centre of gravity distance
Centre of gravity of combined load
Combined load centre for multiple items
Fork extensions — the 50 % rule
Are the extensions too long — and where does the load centre move to?
Step B — Stability
Assess stability as a moment balance about the front axle: does the load moment stay within the permissible moment from the load chart?
Step C — Load chart
Read off the load chart: interpolate the permitted load between two lift heights you have read off — never beyond the chart's end points.
Step D — Geometry over loose numbers
Geometrical Product Specifications — the complete system for dimension, form and surface specifications
Step E — Rules & certificate
The rules worked out: may the forklift be used for lifting people under the order's Annex 2, and is the certificate test passed under TUR's test guidelines?
Step V — Directory
Guided lifting planning: answer questions about load and truck, and the wizard compiles geometry and standards to the correct reading point on your load diagram.
