Trailer-mounted platform: use, driving licence and limits

The trailer-mounted platform is the cheapest way to reach double-digit working heights: it hitches to a normal towing vehicle and needs neither a truck nor a low-loader. In return, it works only on outriggers and cannot drive at height.

Technically, it is an aerial work platform on a car trailer chassis. On site it is levelled on four outriggers; only then can the articulating or telescopic boom with the basket be extended. Common rental models reach working heights of 10 to 16 metres with basket loads of around 200 kg and dead weights mostly under 2 tonnes - light enough for many towing vehicles.

This guide answers the most frequent questions, above all the one about the driving licence, and shows when another platform is the better choice.

The driving licence depends on the maximum permissible mass of the combination of towing vehicle and trailer:

Configuration	Required driving licence
Trailer up to 750 kg maximum permissible mass	the standard car licence category under Czech rules
Trailer over 750 kg, combination up to 3,500 kg	the standard car licence category under Czech rules
Combination over 3,500 up to 4,250 kg	an extended licence under Czech rules
Combination up to 7,000 kg, trailer max. 3,500 kg	the licence for combinations with a heavy trailer under Czech rules

As many trailer-mounted platforms weigh 1,500-2,000 kg, the standard licence is only sufficient with a correspondingly light towing vehicle - in practice, the extended licence for combinations under Czech rules is often required. Before renting, check the maximum permissible mass of the trailer as well as the permissible trailer load and the vertical coupling load of your towing vehicle; both can be found in the vehicle registration certificate. If in doubt, we will give you the data of the specific rental platform in advance - or deliver it from Passau straight to the site, and the driving licence question no longer arises at all.

Tree care and landscaping

The classic: quickly moved between several trees or plots, no truck driver needed, low rental costs.

Roof and facade work

Gutter cleaning, repairs and painting on residential and commercial buildings up to about four storeys - wherever there is a level, load-bearing set-up area next to the building.

Building services and maintenance

Lighting, cameras, small installation work: the trailer-mounted platform stays on site for days at a favourable price, without tying up a self-propelled machine.

• No driving in the working position. Every new position means lowering, retracting the outriggers, moving, re-levelling. With many position changes per day, a self-propelled platform is faster - the comparison Articulating boom lift or scissor lift puts the alternatives into context.
• Set-up area required. The four outriggers need level, load-bearing ground with room for the full outrigger width.
• Sensitivity to wind. As with all light platforms, strict wind limits apply; the specification in the operating manual of the respective machine is decisive.
• Limited basket load. Around 200 kg usually means one or two people with light tools. For material at height, the truck-mounted platform or the scissor lift is the better choice.
• Height ends earlier. Above 16 metres, self-propelled and truck-mounted platforms take over.

1. Check the set-up area: level, load-bearing, no manholes, channels or edges of excavations.
2. Align and secure the trailer, place spreader pads under the outriggers - essential on soft ground.
3. Extend the outriggers until the wheels are relieved; level using the spirit level or automatically.
4. Function test and visual check before the first lift - part of the daily inspection by the operator.
5. Secure the work area; on public roads with the necessary permit under Act No. 361/2000 Coll. (road traffic).

Trailer-mounted platforms are no exception: operators need the required operator qualification in line with applicable Czech safety rules and CSN EN standards, as well as written authorisation from the employer. What this involves is explained in the guide Aerial work platform operator authorisation.

In addition, there is the operator briefing on handover by Luibl - it supplements the qualification but does not replace it.

Used trailer-mounted platforms are relatively inexpensive - but buying only pays off with regular utilisation, because periodic inspection under Government Regulation No. 378/2001 Coll., maintenance and the trailer's roadworthiness test continue to apply. For project-based use, renting remains more economical: an inspected machine, no capital tied up, the next height up when needed.

For orientation: trailer-mounted platforms are among the cheapest platform types of all. The current guide price ranges can be found in the cost guide.

Luibl Rental delivers aerial work platforms with periodic inspection under Government Regulation No. 378/2001 Coll. by low-loader from Passau throughout the Czech Republic, right to the site - including delivery on request, so the driving licence question does not arise. We will clarify which type and height suit your project in a short conversation.

In practice, the trailer-mounted platform competes with two other types. The short comparison helps with the preselection:

Criterion	Trailer-mounted platform	Spider lift	Truck-mounted platform
Working height	10-16 m	up to 40 m	16-57 m
Getting there	behind the towing vehicle	by van or on a trailer	under its own power
Ground	level and load-bearing	also soft, narrow, sloping	paved
Driving in working position	no	no	no
Position changes per day	few	few	many
Entry costs	lowest	high	medium to high

Rule of thumb: one or two locations per day and a towing vehicle available - trailer-mounted platform. Narrow passages, courtyards or sensitive surfaces - spider lift. Constantly changing locations in the street space - truck-mounted platform.

Three points determine whether the job runs smoothly - and they are often only checked on site, when it is too late.

The towing vehicle must add up. What counts is the permissible braked trailer load and the vertical load according to the vehicle registration certificate. A van with a permissible braked trailer load of 2,000 kg can tow a 1,800 kg platform, an estate car with 1,200 kg cannot. The vertical load also determines whether the drawbar load on the tow hitch stays within permissible limits at all.

Manoeuvring needs space or a mover drive. Many trailer-mounted platforms have an electric mover drive that allows the trailer to be moved through gateways and around corners without a towing vehicle. On narrow plots, this is the difference between two minutes and half an hour.

The set-up location must bear the outrigger forces. Under the outriggers, the entire load is concentrated on four small areas. Typical weak points are manhole covers, light wells, freshly backfilled trenches and paving over cavities. Spreader pads increase the load distribution area and are a must on soft or unknown ground.

Trailer-mounted platforms are subject to the same operator duties as any other aerial work platform:

• Daily inspection by the operator before first use: visual and functional check of controls, emergency stop, emergency lowering, outriggers and basket protection.
• Periodic inspection under Government Regulation No. 378/2001 Coll. by a competent person, documented in the logbook. With rental machines, the rental company supplies the inspected machine - the records belong with the machine and should be available on handover.
• Risk assessment for the specific job by the employer, including a rescue plan: who gets a person out of the basket if the operator is incapacitated at height? Emergency lowering must be operable from the ground and its handling practised in advance.
• Observe wind limits. They are given for the specific model in the operating manual and apply to the wind speed at working height, not on the ground - in open terrain and between buildings these can be significantly different values.

For work on public roads, site protection and, if necessary, a permit under Act No. 361/2000 Coll. (road traffic) are added; both belong in the planning before renting.

Which driving licence do you need for a trailer-mounted aerial work platform?

For towing, the required Czech driving licence category depending on the total mass of the combination. With typical platform weights of 1.5-2 t, the extended licence for combinations is usually required. For operation, the required operator qualification in line with applicable Czech safety rules also applies.

How high does a trailer-mounted aerial work platform reach?

Common rental models reach working heights of 10 to 16 metres. Above that, self-propelled platforms and truck-mounted platforms take over.

Can a trailer-mounted platform be towed by a car?

Yes, provided the car's towing capacity and nose weight are sufficient and you hold the required Czech driving licence category for the total weight of the combination. Alternatively, we can deliver the platform directly to your site.

How much does it cost to rent a trailer-mounted platform?

It is one of the most affordable platform types. Current guide price ranges by height and rental period are available in our cost guide.

Who is allowed to operate a trailer-mounted platform?

Persons with the required operator qualification in line with applicable Czech safety rules and CSN EN standards, obtained from an external recognised provider, and with written authorisation from their employer.
