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 Colchester?
Should a recent insurance inspection at a site in Colchester have flagged leveller defects, a survey can show whether repair or replacement makes more sense. Every leveller recommendation we make for a dock in Colchester follows a measured survey of the pit, dock height and the trailers you actually receive.
Fitting out a new warehouse in Colchester with pre-formed pits makes swing-lip levellers a straightforward choice for most general loading from day one.
A single contact at Loading Bay Doors handles your project in Colchester from start to finish. The free site survey and fixed written quote come first, with no obligation to proceed. We then book the installation for times that suit the operation, including out of hours by arrangement, and manage the specialist engineers on site. At the end we commission and test the equipment, walk your team through it and provide the documentation.
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.
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.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
Survey checklist for your dock
- Power supply at each bay, including three-phase availability
- Gaps around trailers where heated or chilled air escapes
- Wind exposure at the dock, which affects door and shelter choice
- Scope to convert ground-level doors into docks or add lift tables
- Access for deliveries, cranes or lifting equipment during installation
- Condition of any existing leveller pit, kerb angles and pit drainage

Regulations and approvals 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 Colchester. 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 Colchester
Do you remove and dispose of the old equipment?
Yes, where it is part of the scope. When we replace doors, levellers, shelters or seals at a site in Colchester, removal and disposal of the old equipment can be included and is itemised in the quote, so it is clear what is covered. If anything should be kept, such as a frame or motor that is still serviceable, we agree that at survey.
Which building and safety rules apply to a site in Colchester?
It depends on which UK nation the site is in. England and Wales use Building Regulations approval, Scotland uses building warrants and Northern Ireland uses building control approval from the council. Workplace safety is regulated by HSE in Great Britain and HSENI in Northern Ireland, and energy rules differ between nations. For your site in Colchester, we check what applies at survey and design to it.
Is the site survey in Colchester free?
Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.
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.
Can a new leveller fit our old pit?
Usually, yes. Levellers are made in standard sizes and many can be supplied to suit an existing pit, but the pit must be square, sound and deep enough. We measure the pit and check the edge steel at survey, and if adjustment or repair is needed we price it separately.
