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 Hertfordshire consider?
Ageing levellers in older docks around Hertfordshire 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 Hertfordshire follows a measured survey of the pit, dock height and the trailers you actually receive.
Mixed bays at a site in Hertfordshire, where some trailers have tail lifts and others do not, may suit a combination of swing-lip and telescopic levellers.
If you are planning swing-lip dock levellers for a site in Hertfordshire, expect four stages. A free survey and fixed written quote come first. We then agree a programme with you, including any out-of-hours work. Specialist installation engineers carry out the installation under our management, with us as your single point of contact. Finally, the equipment is tested, your staff are shown how it works and everything is handed over with its documentation.
What happens when a swing-lip leveller is fitted into an existing pit?
Fitting a swing-lip leveller into an existing pit normally takes one to two working days per bay, with the bay closed throughout. The work runs in a set order:
- The old leveller is isolated, lifted out and removed from site.
- The pit is cleaned and measured, and the edge steel checked for damage.
- The new leveller is lowered in, set level, and welded or anchored to the pit steel.
- The hydraulic power pack and control panel are connected, and any interlocks wired.
- Toe guards, lip and bumpers are checked, then the leveller is run through its full range.
From your side we need the bay emptied and taken out of service, clear access for lifting equipment inside or outside the building, and a suitable power supply, which for most hydraulic levellers is three-phase. If the pit needs repairs, these are done first and can add time, which we confirm in the quote.
How much does a swing-lip dock leveller cost?
A swing-lip dock leveller typically costs £5,200 to £8,800 per leveller, excluding VAT, supply and fit, assuming it goes into an existing, sound pit. New pits, pit repairs, concrete and groundworks are priced separately after survey.
Within that range, the price is driven by:
- Platform length: longer platforms give a gentler gradient but cost more.
- Width and capacity: wider decks and higher load ratings use heavier steel and cylinders.
- Lip length: a longer lip reaches further onto the trailer bed.
- Insulation and sealing: insulated platforms and pit seals for chilled buildings.
- Controls and interlocks: links to the door, restraint or traffic lights.
- Removal and access: taking out the old unit, lifting equipment for delivery and out-of-hours work.
If the pit edge steel is damaged or the pit is out of square, we tell you at survey and price the repair as a separate item, so the leveller price stays clear. The written quote is then the fixed price for the work described.

Planning, building control and safety law 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 Hertfordshire. Planning and Building Regulations questions are never assumed either way: we check what applies at survey, so you know before work is booked.
Questions
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 Hertfordshire 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.
What details do you need from us to quote for swing-lip dock levellers?
To get started, send the site address in Hertfordshire, 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.
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.
