A telescopic-lip dock leveller is a hydraulic pit leveller whose front lip slides forward out of the platform, rather than swinging on a hinge, and can be extended by a controlled amount onto the trailer bed. Telescopic lips commonly extend 500 to 1,000 mm, which lets operators reach over tail lifts, place the lip between pallets and load the last row in a trailer.
Why do sites in Barnet choose this?
Replacing worn swing-lip levellers at a site in Barnet is a good moment to ask whether the current trailer mix now calls for telescopic lips. Retail distribution sites in Barnet receiving both artics and tail-lift rigids at the same bays can handle the whole mix with a telescopic-lip leveller.
A container-handling operation in Barnet can benefit from a telescopic lip, as container floors and chassis heights vary more than standard trailers.
Keeping the dock running is usually the first concern, so we plan around it. After a free survey of your Barnet 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 far should a telescopic lip extend?
A telescopic lip should extend far enough to reach clear bed space on every trailer you load, including over tail lifts, while still leaving a secure overlap on the bed. Telescopic lips commonly extend 500 to 1,000 mm.
- Around 500 mm: suits fleets without tail lifts that need precise placement and end loading.
- Up to around 1,000 mm: reaches over folded tail lifts and across the larger gap left where deep bumpers hold trailers back from the dock edge.
- Platform length: should match the lip, as a long reach on a short platform can leave steep gradients.
- Lip width: full-width lips suit most work, while narrower or tapered lips help with smaller vehicles.
We record the rear details of the trailers you receive, including tail lift depth and bumper projection, then recommend the shortest extension that covers them all. A longer lip than you need adds cost and weight without benefit.
Can a telescopic leveller replace a swing-lip unit in the same pit?
Often yes, a telescopic-lip leveller can replace a swing-lip unit in the same pit, provided the pit is square and deep enough and the edge steel is in good condition. Some telescopic units need a little more depth for the lip mechanism, so we measure carefully at survey.
A typical installation:
- The bay is closed and the old leveller isolated, lifted out and removed.
- The pit is cleaned and measured, and any edge steel repairs carried out.
- The new unit is set in, levelled and fixed to the pit steel.
- The power pack, control panel and lip controls are connected and interlocks wired.
- The platform and lip are tested through their full travel.
You will need to provide a clear bay, access for lifting equipment and a suitable power supply, typically three-phase. Installation commonly takes one to two working days per bay once the pit is ready.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Gaps around trailers where heated or chilled air escapes
- Yard gradient and the slope of the approach to the dock
- Drainage on recessed or sloping dock approaches
- Control positions, isolators and any existing interlocks
- Forklift and pallet truck loads crossing the leveller platform
- Dock height and the mix of trailers you load
Options to discuss
1,000 mm lip extension
A longer reach that clears folded tail lifts and deep bumper projections, so rigids and tail-lift trailers can be loaded at the same bay.
Automatic return control
A single button that withdraws the lip and lowers the platform to its stored position, reducing the risk of a trailer leaving with the lip still out.
Planning, building control and safety law in England
Workplace safety in England is regulated by HSE. For a loading bay in Barnet, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.
Questions about telescopic-lip dock levellers in Barnet
Is the site survey in Barnet 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 details do you need from us to quote for telescopic-lip dock levellers?
To get started, send the site address in Barnet, 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.
How do you price telescopic-lip dock levellers for a site in Barnet?
Guide budgets for supply and fit are £6,800 to £11,800 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.
Do telescopic levellers need more maintenance?
They have more moving parts than a swing-lip leveller, including the lip guides and lip cylinder, so these need checking and lubricating at each service. With planned servicing the extra work is modest. Servicing is chargeable, with the visit price agreed in advance.
Can telescopic and swing-lip levellers be mixed on one dock?
Yes, and many sites do. Fitting telescopic levellers on the bays that receive tail-lift vehicles or need end loading, and swing-lip units on the rest, keeps costs down while covering every vehicle type. Clear bay signage helps drivers reverse onto the right one.
