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 County Down consider?
Operators in County Down who have added electric pallet trucks to their fleet may find an existing leveller too short, making a longer platform worth considering. Every leveller recommendation we make for a dock in County Down follows a measured survey of the pit, dock height and the trailers you actually receive.
Mixed bays at a site in County Down, where some trailers have tail lifts and others do not, may suit a combination of swing-lip and telescopic levellers.
Our part of the job in County Down is to survey, quote and manage; the fitting itself is done by specialist installation engineers working under our management. The survey and the written quote are free. Once the fixed price is accepted, we agree dates that work around your deliveries and shifts, including out-of-hours working where needed. Every installation is tested before handover, and you receive the documentation for each item fitted.
Do dock levellers have to be inspected by law?
Yes, dock levellers are work equipment and must be kept in a safe condition and inspected where deterioration could lead to danger. The law and the regulator depend on where the site is.
- Great Britain: the Provision and Use of Work Equipment Regulations 1998 (PUWER), enforced by HSE.
- Northern Ireland: PUWER (Northern Ireland) 1999, enforced by HSENI.
- Inspection interval: engineering insurers commonly inspect dock levellers under PUWER at 12-month intervals.
- LOLER: most levellers are treated as work equipment under PUWER, but one designed or used to lift people may fall under LOLER, or LOLER (Northern Ireland) 1999, with 6-monthly thorough examination. It depends on the equipment and how it is used; your insurer or competent person will confirm.
- Standard: BS EN 1398:2009 sets the safety requirements for dock levellers. It is current and under review.
Our inspection guide explains what an examiner looks at.
What wears out on a swing-lip dock leveller?
The lip hinge, hydraulic hoses and seals are usually the first parts to wear on a swing-lip leveller, and planned servicing finds most of these problems before they stop a bay.
- Lip hinge: takes an impact every time the lip lands, and suffers badly if trailers reverse into a lip that has not been stored.
- Hydraulics: hoses, cylinder seals and power pack oil age and can leak.
- Velocity fuse: the safety valve that stops the platform dropping if a trailer pulls away must be tested.
- Toe guards and maintenance strut: must be intact and working. HSE guidance notes guards or skirting may be needed where something could be caught.
- Dock bumpers: worn bumpers let trailers strike the leveller and dock edge.
A leveller with a cracked lip hinge, a bent platform or repeated hydraulic leaks may be better replaced than repaired. Service and repair visits are chargeable and agreed before anyone attends.

Questions
Can you work alongside our main contractor on a new build in County Down?
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.
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 County Down, 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.
Do levellers need a three-phase supply?
Most hydraulic dock levellers use a three-phase supply, although some smaller units run on single phase. When replacing like for like, the existing supply can often be reused if it is in good order. We check the supply at survey and include any electrical work in the quote.
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.
