How to Choose Vehicle Ramps for Safe Servicing

A pair of ramps can turn a routine oil change, underbody inspection or exhaust repair into a quicker job - provided they suit the vehicle and are used correctly. Vehicle ramps are simple equipment, but the wrong load rating, approach angle or surface can create a real risk before the technician has even picked up a tool.

For garages, fleet workshops and mobile operators, selection should start with the vehicles actually coming through the door. A lightweight ramp that works well for a small hatchback may not be appropriate for a long-wheelbase van, a loaded pickup or a commercial vehicle. The aim is not simply to get wheels off the ground. It is to create stable, repeatable access at a safe working height.

Start with load rating, not vehicle kerb weight

The stated capacity is the first specification to check, but it needs reading carefully. Manufacturers may quote a rating per ramp, per pair or for an axle. Those descriptions are not interchangeable. Confirm exactly what the figure represents before putting a vehicle on the ramps.

Use the vehicle's gross vehicle weight where there is any prospect of working on a loaded van, fleet vehicle or vehicle carrying equipment. Kerb weight can be a useful reference for private cars, but it does not account for passengers, fuel, tools, racking, stock or modifications. A service van can be significantly heavier at the front or rear axle than its unloaded kerb figure suggests.

Axle loads matter as much as total vehicle weight. When driving onto front ramps, the front axle and the pair of ramps carry the relevant load. Engine position, diesel powertrains, batteries, toolboxes and load distribution all affect that figure. Do not assume equal weight split across both axles.

For mixed workshop use, specify enough margin for the heaviest vehicles routinely handled, rather than buying to the limit for one particular job. This supports safer day-to-day operation and avoids having unsuitable lifting access sitting beside the bay when a larger vehicle arrives.

Choose vehicle ramps that match clearance and wheel size

Approach angle determines whether a vehicle can drive onto a ramp without grounding its bumper, splitter, undertray or exhaust. Low-profile cars need a long, gradual incline. Standard-height ramps with a steep approach may be perfectly sound but unusable for lowered cars, sports models and some modern vehicles with extended front valances.

The ramp platform must also suit the tyre width and diameter. A tyre should sit squarely on the upper section with adequate support across its contact area. Narrow platforms can be awkward with wide performance tyres, while tyre-centre, fleet and commercial work may demand ramps designed for larger wheels and heavier axle loads.

Working height is a trade-off. More height gives better access for drain plugs, undertrays, exhaust clamps and inspection work, but it can make approach angle steeper and requires more clearance above the vehicle. For quick servicing, a modest lift may be all that is needed. For repeated underbody repairs, inspect whether the available height gives a technician enough room to work without poor posture or improvised extensions.

Also consider wheelbase. Short-wheelbase vehicles can reach the raised platform quickly, while long vehicles may bottom out at the transition depending on the ramp profile. Where the workshop sees a broad vehicle mix, low-profile ramps with a longer run-up are often more versatile, although they take up more floor space.

Material and construction affect where ramps can be used

Steel ramps are commonly chosen for heavier workshop and commercial applications. Their strength and durability are useful where equipment is used regularly, but they are heavier to move and should be checked for corrosion, damaged welds, distortion and worn grip surfaces. A damaged steel ramp should be removed from service, not straightened or repaired casually.

Moulded polymer ramps are lighter, easier to handle and often useful for mobile servicing or lighter-duty vehicle work. Quality designs can provide excellent tyre grip and resist many workshop chemicals, but their capacity, storage condition and intended application must be respected. Cracks, splitting, excessive wear and heat damage are reasons to stop using them.

Aluminium ramps offer a useful strength-to-weight balance for some applications, particularly where equipment is carried between sites. However, light weight is not a substitute for capacity. Check the design, load rating and surface condition in the same way as any other ramp.

Whatever the material, look for a broad, stable base and a positive tyre-stop arrangement. The tyre stop should be clearly defined and substantial enough to prevent the vehicle rolling beyond the platform. Grip is equally important. Raised tread, perforated surfaces or moulded texture help retain tyre contact, particularly when tyres or ramp surfaces are damp.

Set up ramps on a suitable working surface

Even correctly specified ramps become unsafe on the wrong floor. Use them only on firm, level and sound ground. Loose gravel, soft tarmac, broken concrete, wet leaves, workshop drains or heavily contaminated floors can allow movement, sinking or loss of traction.

Before use, sweep away loose debris and clean up oil, coolant, diesel and other spills. Check the underside of each ramp for wear or damage, then position both ramps parallel and evenly spaced for the vehicle track. A ramp sitting slightly turned or offset can encourage the tyre to climb unevenly.

The vehicle should be driven on slowly and in a straight line. Where visibility of the tyre position is limited, use a trained banksman rather than relying on guesswork. The banksman should stand clear of the vehicle's path and use agreed signals. Sudden acceleration, wheelspin and sharp steering inputs can displace a ramp or take the tyre off its intended running surface.

Once the tyres are against the stops, select park or first gear as appropriate, apply the parking brake and follow the vehicle manufacturer's guidance. Chock the wheels that remain on the ground where required by the ramp instructions and the task risk assessment. Do not work under a vehicle that appears uneven, moves when checked or has not fully reached both stops.

Ramps are not a substitute for the right lifting method

Vehicle ramps are suited to jobs where wheels remain loaded and the work is carried out below the raised end of the vehicle. Typical examples include oil and filter changes, visual inspections, exhaust work, underbody protection and some brake-line repairs.

They are not suitable for every repair. Wheel removal, suspension work, tyre replacement and many brake jobs require the vehicle to be supported differently. A trolley jack is for lifting, not for holding a vehicle unsupported while work is carried out. Use correctly rated axle stands at approved support points where the repair procedure calls for them, and never combine equipment in a way the manufacturers have not approved.

This distinction matters with EVs and hybrids as well. Underbody access may be needed around battery enclosures, high-voltage cable routing and cooling systems. Ramps can provide useful access, but they do not replace the vehicle-specific isolation process, lock-out controls, insulated tools or EV workshop safety procedures required for high-voltage work.

Build inspection into normal workshop checks

Ramps tend to be treated as permanent background equipment, which is exactly why inspection gets missed. Add them to routine pre-use and workplace checks. Look for cracked mouldings, bent frames, loose fasteners, corrosion, worn tread, damaged tyre stops and contamination that could reduce grip.

Keep pairs together where possible. Mixing different ramp types or heights can leave a vehicle uneven, even if each individual ramp looks serviceable. Mark the rated capacity clearly, store ramps where they will not be struck by vehicles or buried under scrap, and keep operating instructions available for staff who may not use them every day.

For a workshop buying vehicle ramps, the practical choice comes down to the heaviest likely axle load, the lowest clearance vehicle, the space available and the work being carried out. Buy for those real conditions, inspect the equipment properly and make safe set-up part of the job - not an afterthought once the vehicle is already raised.
