A swing-lip dock leveller is a hydraulic ramp set into a pit at the dock edge, with a hinged steel lip along its front. When a trailer is docked the platform rises, the lip swings out, and the platform lowers until the lip rests on the trailer bed, forming a bridge for forklifts and pallet trucks. The lip is typically about 400 to 500 mm long.
What should sites in Northamptonshire consider?
Fitting out a new warehouse in Northamptonshire with pre-formed pits makes swing-lip levellers a straightforward choice for most general loading from day one. Ageing levellers in older docks around Northamptonshire can often be replaced like for like in the existing pit, avoiding new concrete work if the pit is sound.
Mixed bays at a site in Northamptonshire, where some trailers have tail lifts and others do not, may suit a combination of swing-lip and telescopic levellers.
Our part of the job in Northamptonshire is to survey, quote and manage; the fitting itself is done by specialist installation engineers working under our management. The survey and the written quote are free. Once the fixed price is accepted, we agree dates that work around your deliveries and shifts, including out-of-hours working where needed. Every installation is tested before handover, and you receive the documentation for each item fitted.
How long should a dock leveller platform be?
A leveller platform should be long enough to keep the slope gentle across the full range of trailer heights you load, because the steepest gradient decides which handling equipment can use it safely. A longer platform spreads the same height difference over a greater distance.
- Know your trailer mix: with a dock typically around 1,200 mm high and trailer beds ranging from roughly 900 to 1,600 mm, the height difference can be considerable.
- Check your equipment: low-clearance electric pallet trucks cope with less gradient than a counterbalance forklift with good ground clearance.
- Common lengths: platforms are commonly made from around 2 to 3.5 m long, with longer units where trailers sit very low or very high.
- Width: a wider platform gives more room when pallets sit close to the trailer sides.
When replacing a unit, the pit size limits what can be fitted, so we measure the pit and record your trailer heights at survey before recommending a length.
Which trailers and loads suit a swing-lip leveller?
A swing-lip leveller suits everyday loading of standard trailers, where pallets sit a little way back from the rear of the trailer and the lip has room to land on the bed. It is a common choice for general distribution.
- Good fit: curtain-siders and box trailers loaded by forklift or pallet truck, with the lip landing behind the first row of pallets.
- Less suited: trailers loaded right up to the rear doors, because the lip needs clear bed space to rest on.
- Tail-lift vehicles: a folded tail lift can stop the lip reaching the bed.
- End loading: loading the last row of pallets at the very rear is awkward with a fixed-length lip.
Where these situations are common, a telescopic-lip dock leveller places its lip exactly where it is needed. Many sites fit both types across their bays, matching each bay to the vehicles it receives.

Which rules apply in England?
Sites in Northamptonshire fall under the rules for England.

We check what applies at survey and build any approvals into the plan.
Questions
Do you cover Northamptonshire for swing-lip dock levellers?
Yes. We take on swing-lip dock levellers for businesses in Northamptonshire and across Northamptonshire. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
Will you deal with building control and planning for a project in Northamptonshire?
We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.
How long does a replacement leveller take to arrive?
Lead times depend on size, specification and the manufacturer, and we confirm them in the written quote. The existing leveller can usually stay in use until the replacement is on site, so the bay is only closed for the installation itself.
What happens if a trailer pulls away with the lip on its bed?
The platform drops until its safety system stops it. Hydraulic levellers have a velocity fuse that arrests the fall, but the event can still damage the leveller and endanger anyone on it, which is why dock traffic lights, restraints and key control are used to prevent early drive-away.
