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.
Where does this fit at a dock in Potters Bar?
Distribution warehouses in Potters Bar loading curtain-siders and box trailers every day are typical users of swing-lip levellers, which handle routine pallet loading well. Every leveller recommendation we make for a dock in Potters Bar follows a measured survey of the pit, dock height and the trailers you actually receive.
Mixed bays at a site in Potters Bar, where some trailers have tail lifts and others do not, may suit a combination of swing-lip and telescopic levellers.
We never ask you to commit before you have a fixed price. A free survey at your Potters Bar site comes first, followed by a written quote. When the order goes ahead, we plan the installation around your operation, book any out-of-hours working you need and manage the specialist installation engineers on site. The job ends with a full test, a run-through for the people who will use the equipment and a set of handover documents.
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.
Do dock levellers have to be inspected by law?
Yes, dock levellers are work equipment and must be kept in a safe condition and inspected where deterioration could lead to danger. The law and the regulator depend on where the site is.
- Great Britain: the Provision and Use of Work Equipment Regulations 1998 (PUWER), enforced by HSE.
- Northern Ireland: PUWER (Northern Ireland) 1999, enforced by HSENI.
- Inspection interval: engineering insurers commonly inspect dock levellers under PUWER at 12-month intervals.
- LOLER: most levellers are treated as work equipment under PUWER, but one designed or used to lift people may fall under LOLER, or LOLER (Northern Ireland) 1999, with 6-monthly thorough examination. It depends on the equipment and how it is used; your insurer or competent person will confirm.
- Standard: BS EN 1398:2009 sets the safety requirements for dock levellers. It is current and under review.

- Yard gradient and the slope of the approach to the dock
- Access for deliveries, cranes or lifting equipment during installation
- Headroom above the opening and which track type will suit it

Which rules apply in England?
Sites in Potters Bar fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about swing-lip dock levellers in Potters Bar
Do you cover Potters Bar for swing-lip dock levellers?
Yes. We take on swing-lip dock levellers for businesses in Potters Bar and across Hertfordshire. 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.
Can you work outside our normal operating hours in Potters Bar?
Yes, by arrangement. Evening, night and weekend working can be planned so the installation causes as little disruption as possible to your loading schedule. Out-of-hours work can affect the price, so mention it at the survey and we will include it in the written quote. The agreed times are confirmed in the programme before the job starts.
What details do you need from us to quote for swing-lip dock levellers?
To get started, send the site address in Potters Bar, 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.
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.
Do levellers need a three-phase supply?
Most hydraulic dock levellers use a three-phase supply, although some smaller units run on single phase. When replacing like for like, the existing supply can often be reused if it is in good order. We check the supply at survey and include any electrical work in the quote.
