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 Sunbury-on-Thames?
Fitting out a new warehouse in Sunbury-on-Thames with pre-formed pits makes swing-lip levellers a straightforward choice for most general loading from day one. Ageing levellers in older docks around Sunbury-on-Thames 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 Sunbury-on-Thames follows a measured survey of the pit, dock height and the trailers you actually receive.
How does an installation in Sunbury-on-Thames work? First, a free, no-obligation survey to measure up and understand the operation. Next, a fixed written quote. Then a programme agreed with you, so the work fits around deliveries, with out-of-hours slots if needed. The installation itself is carried out by specialist engineers who answer to us, and it finishes with testing, a walk-through for your staff and a handover pack.
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.
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.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What we look at on site
- Access for deliveries, cranes or lifting equipment during installation
- Wall and steel structure for door, shelter and bumper fixings
- Drainage on recessed or sloping dock approaches
- Age and condition of the equipment already in place
- Wind exposure at the dock, which affects door and shelter choice
- Lighting inside trailers and at the dock face
Options to discuss
Insulated leveller
An insulated platform with perimeter seals around the pit that reduces cold loss through the floor of the bay at chilled and frozen docks.
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.
Which rules apply in England?
Lift tables and dock lifts in Sunbury-on-Thames may fall under LOLER, with thorough examination at least every 12 months, or every 6 months where people are lifted. It depends on the equipment and how it is used, and your insurer or competent person will confirm. Dock levellers are usually treated as work equipment under PUWER. We check what applies at survey.
Questions about swing-lip dock levellers in Sunbury-on-Thames
How do you price swing-lip dock levellers for a site in Sunbury-on-Thames?
Guide budgets for supply and fit are £5,200 to £8,800 per leveller, excluding VAT. The figure moves with size, insulation, the operator, electrics, access, any pit or groundworks and out-of-hours working. Where levellers are involved, the guide assumes an existing, sound pit. After the free survey you receive a fixed written quote, and that is the price for the agreed scope.
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 Surrey 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.
Is the site survey in Sunbury-on-Thames 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 capacity of leveller do we need?
The leveller needs to be rated for the heaviest combined load of forklift and goods that will cross it, allowing for the truck moving over it. General-purpose levellers are typically rated around 60 kN, with heavier ratings for heavy goods or large forklifts. We confirm the rating after looking at your equipment.
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.
