Capacity calculator

What your truck still lifts.

Every attachment puts weight in front of the mast and moves the load away from the front axle. Both cost capacity. Estimate the residual capacity of your truck with an e-l-m attachment, integrated or hook-on, before you order.

Start calculating
Integrated e-l-m fork positioner on a STILL forklift truck, seen at an angle from the front, with the frame, the forks and the front wheel
An integrated e-l-m fork positioner on a STILL truck. Its frame takes the place of the truck’s own fork carriage.

Your truck, your attachment, your load.

Fill in the figures from your truck’s data sheet. We start you with the 2.5 t example from our catalogue: the integrated 6IFPF 25 1450 against the hook-on 6HFPF 25 1450, at the same width.

Indicative
This is a simple estimate. Even our advanced calculator, with the full truck data, works to about ±5 %.
The plate rules
The capacity plate on your truck always rules. Let e-l-m verify the figure for your truck before you rely on it.
Not included
The truck’s own fork carriage, which an integrated unit replaces, is not credited here. Equipment mounted differently, such as fork shoes, cannot be calculated.

What the letters mean.

The same symbols as in our catalogue and in our advanced calculator.

The same unit from the side. x runs from the centre of the front wheel to the fork face.

How this estimate works: the moments about the front axle

P1 =P · (x + a) − Q · (x + E)x + C + a1

Rounded down to the nearest 10 kg, as on a capacity plate, and never above P.

P:

Rated capacity

What the truck may lift at load centre a, from its capacity plate or data sheet.

a:

Load centre

Fork face to the centre of gravity of the load that P is rated at. 500 or 600 mm on most trucks (ISO 2328 classes 2–5).

x:

Front axle to fork face

From the centre line of the front wheels to the fork face.

Q:

Attachment weight

From the model’s table in the catalogue.

E:

Centre of gravity (EH)

How far in front of the fork carriage the attachment’s centre of gravity sits, horizontally. From the catalogue table.

C:

Lost load centre

How far the attachment moves the fork face forward. The smaller, the better.

a1:

New load centre

Fork face to the centre of gravity of the load you actually carry.

P1:

Residual capacity

What the truck may lift with the attachment fitted, at a1.

The further out the load, the less the truck lifts.

Our advanced calculator knows the trucks. Pick the brand and model of your truck and the e-l-m attachment, and it fills in the data. Calculate up to ten load centres and send the result by email.
