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 Forth Valley?
Should a recent insurance inspection at a site in Forth Valley have flagged leveller defects, a survey can show whether repair or replacement makes more sense. Mixed bays at a site in Forth Valley, where some trailers have tail lifts and others do not, may suit a combination of swing-lip and telescopic levellers.
Distribution warehouses in Forth Valley loading curtain-siders and box trailers every day are typical users of swing-lip levellers, which handle routine pallet loading well.
We keep the process simple for sites in Forth Valley. A free survey tells us what the dock needs; a fixed written quote tells you what it will cost and what is included. We then organise the installation, with specialist engineers under our management and a programme agreed around your shifts. Night and weekend work is available by arrangement. Before we leave, the new equipment is tested, demonstrated and handed over with its documentation.
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.
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.

Questions
Do you cover Forth Valley for swing-lip dock levellers?
Yes. We take on swing-lip dock levellers for businesses in Forth Valley and across Forth Valley. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
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 Forth Valley, 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 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.
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.
