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.
Why do sites in Perth and Kinross choose this?
Ageing levellers in older docks around Perth and Kinross can often be replaced like for like in the existing pit, avoiding new concrete work if the pit is sound. Distribution warehouses in Perth and Kinross loading curtain-siders and box trailers every day are typical users of swing-lip levellers, which handle routine pallet loading well.
Every leveller recommendation we make for a dock in Perth and Kinross follows a measured survey of the pit, dock height and the trailers you actually receive.
The survey is free, the quote is written and the price is fixed: that is how every installation in Perth and Kinross begins. We then manage the work from start to finish. Fitting is carried out by specialist installers under our management, phased so the operation keeps moving, and nights or weekends can be booked by arrangement. On the final day we test the equipment with you and hand over the operating and maintenance information.
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.
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.

What do the rules in Scotland mean for the work?
Lift tables at Scottish sites are lifting equipment under LOLER, which means thorough examination at least every 12 months, or every 6 months if people are lifted, depending on the equipment and its use. For a site in Perth and Kinross, your insurer or competent person will confirm the interval, and we check what applies at survey.
Questions
Can you work alongside our main contractor on a new build in Perth and Kinross?
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.
How long does installation take at a site in Perth and Kinross?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
Can a swing-lip leveller be used as a ramp to the yard?
No, a leveller should only be used to bridge a docked trailer. The lip and toe guards are designed to work with a trailer bed in place, and the platform is not built as a ramp down to yard level. Where you need ground-level access, a separate door or a lift table is the safer answer.
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.
