Access steps provide safe, repeatable entry into trailers and rigid bodies for load checks, securing goods and routine inspection. The correct design depends on deck height, rear frame layout, available stowage space and how often the step is used. Typical options include pull-out drop-down ladders, platform steps, scissor cartridges and heavy-duty slide-out assemblies.
Select the simplest design that provides comfortable first-step height, stable footing and reliable locking. Higher decks or frequent entry usually benefit from three rungs or an integral platform. Side access applications must maintain side guard integrity and avoid obstruction when stowed.
Where access steps are used
- Rear access for loading, unloading and internal inspection.
- Side access for kerbside entry on curtain-sided vehicles and bodies with side doors or hatches.
- Low deck / step-frame applications where geometry and underrun structures limit space.
Selection criteria
- Deck height: influences rung count and first-step comfort.
- Rear frame and underrun layout: defines cartridge and slide clearance.
- Frequency of use: higher utilisation favours platforms or heavy-duty assemblies.
- Stowage and locking: steps should secure positively and remain protected in transit.
- Surface grip: anti-slip treads and drainage reduce slip risk.
Maintenance
- Weekly visual check of locks, pivots and slides.
- Monthly movement test and fastener inspection.
- Keep treads clean and renew anti-slip surfaces if grip reduces.

2 Rung Pull-Out Drop-Down Step
A compact, slide-out ladder that drops into position to provide two footholds. Suitable for moderate deck heights and occasional entry where space is limited. The mechanism stows flush within the rear structure when not in use.
3 Rung Pull-Out Drop-Down Step
A pull-out, drop-down ladder providing three rungs for improved first-step height and comfort on higher decks or frequently accessed bodies. Offers simple deployment and secure stowage.
2 Rung Pull-Out Drop-Down Step With Platform
Two-rung ladder with an integral standing platform to improve stability when transitioning into the body. Suited to repeated access where additional footing is beneficial.
3 Rung Pull-Out Drop-Down Step With Platform
Three rungs combined with a platform to provide a stable transition point and improved ergonomics on taller bodies or high-use fleets. Suitable where operators carry loads or enter frequently.
Pull-Out Scissor Steps (3 rungs)
A cartridge-style assembly that extends and drops down to form three flat steps. The compact housing allows installation at the rear or at side access points where a self-contained unit is preferred.
Heavy Duty Over-And-Under Slide Out Step
A reinforced slide-out platform designed to work around the underrun bar. Provides a wide, stable standing surface and is typically specified on low rear decks such as step-frame double decks.
Slide Out Heavy Duty Step
A robust slide-out platform intended for frequent use and higher loads. Offers a solid standing area and straightforward maintenance access.
Drop Down Side Access Step
A heavy-duty drop-down step used where side entry is required. Common on rigids and multi-drop operations. When stowed, the assembly forms part of the side guard and locks securely in place.
FAQs
When should I choose a 3-rung step instead of a 2-rung?
A 3-rung system is useful where the rear deck is higher or when operators enter the body frequently. The lower first tread improves ergonomics. Two-rung steps are generally suitable for moderate deck heights or occasional access.
What is the benefit of an integral platform?
A platform provides a stable transition point before stepping inside the vehicle. It reduces slips and improves balance during repeated entry and exit.
How do slide-out heavy-duty steps interact with underrun bars?
These assemblies are shaped to work around the underrun structure, offering a stable standing surface without reducing ground clearance. Confirm bar geometry and locking positions during specification.
Are side access steps suitable for curtain-siders and urban delivery vehicles?
Yes. Side access steps are widely used in multi-drop and kerbside delivery operations. When stowed, the step should lock securely and form part of the side guard.
Do I need a grab handle when using access steps?
A grab handle is recommended wherever practicable. It supports three-point contact and reduces slip risk, especially in wet or contaminated conditions.
What routine checks should be carried out?
Check that locks engage fully, inspect hinges, pivots and slides for wear, confirm fasteners remain tight and ensure treads stay clean with effective anti-slip surfaces. Increase inspection frequency for high-use fleets.
