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.
What matters for telescopic-lip dock levellers in Derry/Londonderry?
A container-handling operation in Derry/Londonderry can benefit from a telescopic lip, as container floors and chassis heights vary more than standard trailers. Before recommending a lip extension for a dock in Derry/Londonderry, we record the trailers that actually arrive, including tail lifts and rear overhangs.
Parcel and courier hubs in Derry/Londonderry with varied vehicle types can use the longer lip reach to serve more of their fleet from fewer bays.
We never ask you to commit before you have a fixed price. A free survey at your Derry/Londonderry 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 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.
How are drive-away risks managed while the lip rests on a trailer?
Drive-away risks are managed by stopping the vehicle leaving until loading has finished and the lip has been withdrawn, using traffic lights, vehicle or trailer restraints, or the person in charge keeping the keys or paperwork. HSE workplace transport guidance (HSG136) and the HSE loading factsheet (followed by HSENI in Northern Ireland) call for safeguards against drivers driving away too early.
- Why it matters: a lip resting on the bed is only safe while the trailer stays put, and trailer creep during forklift loading can open a gap at the dock edge.
- Equipment duties: the leveller is work equipment under PUWER 1998 in Great Britain or PUWER (Northern Ireland) 1999, so it must be maintained and inspected where deterioration could lead to danger. Engineering insurers commonly inspect at 12-month intervals.
- Standard: BS EN 1398:2009 sets the safety requirements for dock levellers and is current, under review.
Enforcement is by HSE in Great Britain and HSENI in Northern Ireland. Our guide to preventing drive-away and trailer creep compares the safeguards.
The same published guide range applies across Northern Ireland; access, out-of-hours working and site conditions are confirmed at the free survey.
What we look at on site
- Traffic routes for vehicles and separation of pedestrians
- Power supply at each bay, including three-phase availability
- Gaps around trailers where heated or chilled air escapes
- Lighting inside trailers and at the dock face
- Clear opening width and height for each door
- How drivers are prevented from pulling away too early
Options to discuss
Insulated cold store version
An insulated platform with perimeter seals for chilled and frozen docks, often paired with an inflatable shelter and an insulated dock door.
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.
What do the rules in Northern Ireland mean for the work?
The equipment regulations have separate Northern Ireland versions: PUWER (Northern Ireland) 1999 for work equipment such as dock levellers and doors, and LOLER (Northern Ireland) 1999 for lifting equipment such as scissor lift tables. For sites in Derry/Londonderry, your insurer or competent person will confirm inspection intervals, and we check what applies at survey.
Questions about telescopic-lip dock levellers in Derry/Londonderry
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 Derry/Londonderry, 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.
What details do you need from us to quote for telescopic-lip dock levellers?
To get started, send the site address in Derry/Londonderry, 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 you work alongside our main contractor on a new build in Derry/Londonderry?
Yes. For new warehouses and fit-outs, we can supply and install the dock package as part of a wider project, working to the main contractor's programme, site rules and permits. We will need drawings, dock levels and the programme, and we coordinate pit details, power supplies and door openings with the relevant trades before installation begins.
What overlap should the lip have on the trailer bed?
The lip should rest on the trailer bed with the overlap the manufacturer specifies, so it cannot slip off as the trailer moves under load. Extending further than needed adds no benefit. We show dock staff what a correct overlap looks like at handover.
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.
