How to Measure Your Forklift for a Tipping Skip

Before ordering a forklift tipping skip, it is important to check more than the volume of waste you need to handle. The attachment must fit your forklift forks, remain within the truck’s safe lifting capacity and operate properly within the available space on your site.

Forklift tipping skips are designed to slide directly onto the forks, but forklift trucks and skip models are not all identical. Fork width, thickness, length and spacing can vary, while the weight and dimensions of the skip change according to its capacity and construction.

Taking a few measurements before ordering helps prevent fitment problems and gives you the information needed to select a suitable model. This guide explains what to measure, where to find the relevant forklift information and which details to provide when asking for help.

What Should You Check Before Ordering a Forklift Tipping Skip?

The main checks are:

1. The width of each forklift fork.
2. The thickness of each fork.
3. The usable fork length.
4. The spacing between the forks.
5. The forklift’s lifting capacity.
6. The rated load centre.
7. The required tipping height.
8. The weight of the skip and its expected contents.
9. The available width, height and turning space on site.
10. The type of tipping mechanism required.

These checks cover two separate questions. First, will the attachment physically fit the forklift? Second, can the forklift safely lift and operate the attachment when loaded?

Quick Forklift Measurement Checklist

How to Measure Forklift Fork Width

Fork width is the horizontal measurement across one fork blade. Measure across the widest flat section of the blade rather than estimating from a photograph or relying only on the forklift model.

Record the measurement in millimetres. Measure both forks if there is any sign that they have been repaired, replaced or worn differently.

The fork width must be less than the internal width of the tipping skip’s fork pockets. A small amount of clearance is necessary so the forks can enter the pockets without binding, but the fit should still match the manufacturer’s specification.

How to Measure Forklift Fork Thickness

Fork thickness is measured vertically through the fork blade. Take the measurement on the straight section near the fork heel, where the blade is normally thickest, unless the attachment specification instructs otherwise.

A fork may be narrow enough to fit the pocket width but still be too thick to enter the pocket height. This is why width and thickness must be recorded separately.

Forks can also become worn through use. If the forklift is old or heavily used, do not rely entirely on dimensions listed in an old specification sheet. Measure the forks currently fitted to the machine.

How to Measure Forklift Fork Length

Measure fork length from the front face of the fork carriage to the tip of the blade. Record the usable length in millimetres.

Fork length matters because the attachment must be properly supported. The forks should enter the fork pockets to the position specified for the attachment, and the skip must then be secured using its supplied retention system.

Do not operate a tipping skip with inadequate fork engagement or assume that the retaining chain compensates for unsuitable forks. The chain or retention device is an additional securing measure, not a substitute for correct fitment.

How to Measure the Distance Between the Forks

The two forks must line up with the tipping skip’s fork pockets. Measure the fork spacing after positioning the forks in the arrangement you expect to use.

Fork spacing can be described in two ways:

• Inside-to-inside: the clear gap between the inner edges of the two forks.
• Centre-to-centre: the distance between the centreline of one fork and the centreline of the other.

Either measurement can be useful, but always state which one you have taken. Sending a number without identifying the measurement method can create confusion.

It is also worth checking how far the forks can be adjusted across the carriage. A tipping skip may fit the individual fork dimensions but still be unsuitable if the truck cannot position the forks in line with the pockets.

Check the Forklift Data Plate

The forklift’s data plate provides essential information about its rated capacity. It will usually identify the truck model, maximum capacity and the load centre at which that capacity applies.

The headline capacity should not be treated as a guarantee that the truck can lift any load below that weight in every position. Available capacity can change according to:

• The distance of the load from the fork carriage.
• The height to which the load is raised.
• The size and centre of gravity of the attachment.
• Any derating applied for an attachment.
• The forklift’s mast and configuration.

If the truck’s capacity plate does not account for the intended attachment, seek competent guidance before use. The forklift must remain suitable for the complete loaded arrangement, not merely the empty skip.

Calculate the Total Working Load

When checking capacity, include both the empty weight of the tipping skip and the expected weight of its contents.

For example, a large skip filled with light cardboard may weigh far less than the same skip filled with metal offcuts, wet soil or rubble. Physical volume and material weight are not interchangeable.

This is why choosing the biggest skip available is not always the safest or most efficient option. Dense material can reach the forklift’s permitted weight before the skip is full.

For help selecting volume based on waste type and frequency, read our forklift tipping skip capacity guide.

Understand Load Centre and Attachment Reach

A forklift’s rated capacity normally applies at a stated load centre. When a tipping skip is fitted, the load may sit further forward than a conventional pallet load. This can reduce the forklift’s effective lifting capacity.

The larger and longer the skip, the further forward its combined centre of gravity may be positioned. The actual effect depends on the attachment, its contents and the forklift configuration.

Do not assess suitability using the skip’s safe working load alone. The attachment’s rating tells you what the attachment is designed to handle, while the forklift’s capacity determines what the truck can safely lift in the intended configuration. Both limits must be respected.

Measure the Required Tipping Height

If the skip will discharge into a larger waste container, measure the height of the container wall. The forklift must raise the tipping skip high enough for the body and discharged material to clear the edge safely.

When measuring, consider:

• The height of the receiving container.
• The position of the tipping skip on the forks.
• The movement of the body during discharge.
• The clearance required to avoid striking the container.
• The forklift’s capacity at the required lift height.
• Overhead beams, doors, lighting and other obstructions.

Maximum mast lift height is not the only consideration. The forklift must retain sufficient capacity and stability at the height at which the load will actually be tipped.

Check the Operating Space Around the Forklift

A tipping skip can be considerably wider and longer than the forklift forks themselves. Measure the areas through which it will travel rather than checking only whether it fits the truck.

Inspect:

• Warehouse aisles.
• Door openings.
• Pedestrian barriers.
• Turning areas.
• Ramps and changes in floor level.
• The approach to the discharge point.
• Overhead restrictions.
• The space needed for the skip body to tip forward.

A high-capacity skip may reduce the number of journeys required, but it can be less practical where access is restricted. The most efficient capacity is the one that safely fits the forklift, load and site—not simply the largest available size.

Choose the Correct Tipping Mechanism

Once fitment and capacity have been checked, consider how the skip will be emptied.

A standard roll-forward forklift tipping skip provides a straightforward solution for general waste handling and controlled discharge.

An auto-release forklift tipping skip is designed for operations where the skip is emptied frequently or tipped at height. Its automatic release system allows normal tipping without the operator leaving the forklift cab.

For abrasive materials, tougher industrial waste or demanding environments, consider whether a heavy-duty forklift tipping skip is more appropriate.

For a detailed comparison, read our guide to auto-release vs standard roll-forward tipping skips.

Measurements to Send Before Asking for a Quote

If you are unsure which tipping skip is suitable, provide as much of the following information as possible:

• Forklift manufacturer and model.
• A clear photograph of the forklift data plate.
• Fork width in millimetres.
• Fork thickness in millimetres.
• Usable fork length in millimetres.
• Inside or centre-to-centre fork spacing.
• Maximum adjustment available across the carriage.
• The material you intend to carry.
• The approximate maximum material weight.
• The volume of waste produced.
• The height of the receiving container.
• The number of tipping cycles expected each day.
• Any restricted doorways, aisles or turning areas.

Photographs of the forks, forklift data plate and discharge area can also help clarify the application.

Common Forklift Measurement Mistakes

Only checking the forklift’s headline capacity

The rated figure on the truck may apply at a particular load centre and height. The effect of the attachment and its forward projection must also be considered.

Measuring the gap but not the individual forks

Fork spacing alone does not confirm fitment. Each fork must fit within the width and height of the relevant fork pocket.

Assuming all forks are standard

Fork dimensions vary between forklift models and applications. Forks may also have been replaced during the machine’s working life.

Choosing capacity based only on volume

A large skip filled with dense material can exceed the permitted load even when it appears only partly full.

Ignoring the discharge container

The skip may fit the forklift but still be unable to clear the container wall or operate within the available tipping space.

Forgetting to check fork adjustment

The forks may be individually suitable but unable to move into the spacing required by the attachment pockets.

Using photographs instead of measurements

Photographs are helpful supporting information, but perspective makes it difficult to confirm dimensions accurately. Always include measurements.

A Simple Five-Step Fitment Check

Frequently Asked Questions

Are forklift tipping skips universal?

No attachment should be assumed to fit every forklift automatically. Fork dimensions, spacing, truck capacity and the attachment specification must be checked before ordering and use.

What fork measurements do I need?

Measure the width, thickness and usable length of each fork, together with the spacing between them. State whether the spacing measurement is inside-to-inside or centre-to-centre.

Where do I find my forklift’s lifting capacity?

Check the forklift data plate and operating documentation. The capacity must be considered at the relevant load centre and lifting height.

Does the tipping skip reduce forklift capacity?

A fork-mounted attachment adds weight and can move the combined centre of gravity forward. This may reduce the load the forklift can safely handle compared with a conventional pallet positioned closer to the carriage.

Should I include the skip’s own weight?

Yes. Capacity calculations must include the empty attachment and the maximum expected weight of the material inside it.

Can I choose a skip using only the forklift model?

The model is useful, but current fork measurements and data-plate information should still be provided. Forks may vary or may have been replaced since the truck was manufactured.

How do I know whether I need auto release?

Auto release is most useful where the skip is tipped frequently, discharged at height or used in an operation where keeping the driver in the cab during normal tipping improves efficiency.

What should I do if I am unsure about compatibility?

Provide the forklift model, data-plate photograph, fork measurements, waste details and tipping height before ordering so the application can be reviewed.
