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 matters for swing-lip dock levellers in Trowbridge?
Mixed bays at a site in Trowbridge, where some trailers have tail lifts and others do not, may suit a combination of swing-lip and telescopic levellers. Ageing levellers in older docks around Trowbridge can often be replaced like for like in the existing pit, avoiding new concrete work if the pit is sound.
Every leveller recommendation we make for a dock in Trowbridge follows a measured survey of the pit, dock height and the trailers you actually receive.
Keeping the dock running is usually the first concern, so we plan around it. After a free survey of your Trowbridge site and a written quote at a fixed price, we agree when each bay can be released and whether any work should happen out of hours. Specialist installation engineers working under our management then fit the equipment, and we test it and hand over the documentation before the bay goes back into use.
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.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Yard gradient and the slope of the approach to the dock
- Whether planning, building control or a building warrant may be needed
- Wall and steel structure for door, shelter and bumper fixings
- Gaps around trailers where heated or chilled air escapes
- Scope to convert ground-level doors into docks or add lift tables
- Wind exposure at the dock, which affects door and shelter choice
Options to discuss
Interlocked controls
Control panels linked to the dock door, vehicle restraint or traffic lights so the leveller can only be operated when the dock is safe.
Long-platform leveller
A longer platform that keeps gradients gentle where trailer heights vary widely or low-clearance electric pallet trucks are used across the bay.
Which rules apply in England?
Powered doors and dock equipment installed in England may carry the UKCA or the CE mark, and doors are covered by the product standard BS EN 13241. We hand over the relevant documentation for each item fitted in Trowbridge. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions about swing-lip dock levellers in Trowbridge
What details do you need from us to quote for swing-lip dock levellers?
To get started, send the site address in Trowbridge, the number of bays or openings, approximate sizes, and photos of the dock from inside and outside. Tell us what vehicles you load, what goods you handle and any temperature requirements. Drawings help on new builds. We then arrange the free survey and confirm the details before the written quote is issued.
Is VAT included in your guide prices for swing-lip dock levellers?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in Wiltshire as everywhere else: for swing-lip dock levellers, it is £5,200 to £8,800 per leveller, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
Can you work alongside our main contractor on a new build in Trowbridge?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
Can a swing-lip leveller be used as a ramp to the yard?
No, a leveller should only be used to bridge a docked trailer. The lip and toe guards are designed to work with a trailer bed in place, and the platform is not built as a ramp down to yard level. Where you need ground-level access, a separate door or a lift table is the safer answer.
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.
