Technical data

Product description

Construction trailer for transporting machinery and bulk materials

This tandem construction trailer combines a robust tipping body made from 4 mm S355 steel with standard aluminium loading ramps. It transports construction machinery as well as gravel, soil and construction waste.

Two machines in one: machinery transporter and tipper

That is the idea behind this trailer.

• As a machinery transporter: The 3.5 m-long aluminium ramps are supplied as standard, the body has eight internal lashing points, and the 980 mm platform height keeps the loading angle shallow.
• As a tipper: The body tips backwards to 50°, and the hydraulic tailgate opens at the same time.

What this means in practice: Take a mini excavator to the site, remove the excavated material, deliver gravel – all with one trailer instead of two. For landscapers, local authorities and smaller construction companies, this is the right combination.

8.320 kg payload with an unladen weight of 2.680 kg

The ratio is remarkable: the trailer carries more than three times its own weight.

What it can transport: Mini excavators weighing up to around 8 tonnes, wheel loaders, vibrating plates, site materials – and around 7 to 8 tonnes of gravel with a body volume of 4,5 m³, without exceeding the payload.

A technically permissible weight of 11.000 kg applies for on-site use – on the business premises and in the field.

Aluminium ramps: 3.5 m long and stored ready to hand

The ramps measure 3.500 × 465 mm and are stored between the running gear and the load body.

Why this is the right solution: Ramps stored beneath the body are always with you and do not take up any loading space. Ramps left in the accompanying vehicle's boot will have been forgotten by the third job.

Why aluminium: Steel ramps of this length are so heavy that a second person is needed to hook them on. One person can handle the aluminium ramps alone.

About the ramp length: At a platform height of 980 mm, 3.5 m ramps give a shallow loading angle – important for machines with low ground clearance and for tracked vehicles.

Eight internal lashing points

Two at the front on the floor, four on the floor, and two at the rear on the side wall.

Why their position matters: A machine must be secured in every direction – forwards against braking forces, backwards against acceleration, and sideways against centrifugal forces. Lashing points inside the body allow diagonal lashing, securing the load in all three directions at once.

S355 body with 4 mm wall thickness

S355 is a higher-strength structural steel – at the same sheet thickness, it can withstand considerably more load than standard structural steel. The floor and sides are made to the same thickness, because the sides can also be struck when transporting machinery.

As optional equipment the entire body is available in HARDOX 450HB – wear-resistant steel for businesses that mainly transport sharp-edged construction waste and recycling materials.

Rounded front wall

The full-height curve has a practical purpose: material slides out completely when tipping, rather than getting stuck in the corner. With damp soil and clay, this is the difference between an empty and a half-full body.

ALB supplied as standard

The automatic load-sensing brake force regulator is included as standard equipment – on a trailer whose weight more than triples between empty and loaded, this is the right specification. ALB Premium is available as an option.

Universal drawbar

The rigid drawbar is designed for overrun and underrun hitching, with a rigid towing eye Ø 40 for overrun hitching. A K80 ball hitch is available as optional equipment.

Turn the tipper into a load carrier

With the optional 800 mm extensions with a Plexiglas viewing window and rear swinging tailgate, the volume increases considerably – making the trailer suitable for green waste, wood chips and light bulk materials.

Additional equipment

• Hydraulic tailgate with HARDOX surface, tilting downwards
• Swinging split tailgate
• Hydraulic angled support leg (no extra charge)
• Side underrun protection to 89/297/EEC
• Toolbox, front wall cover
• Plastic mudguards on the front axle

Applications

Landscaping, construction and civil engineering companies, local authorities and public works departments, equipment hire, agriculture involving machinery transport, forestry businesses, waste disposal companies.

Operating notes

• Check the towing vehicle's nose weight: up to 2.000 kg.
• When loading, hook the ramps on securely and check that they cannot slip.
• Secure machinery against slipping and tipping during transport – the lashing points allow diagonal lashing.
• Keep everyone clear of the space between the ramp and machine while loading.
• When tipping, ensure the ground is level and firm.
• Before tipping, check that the tailgate can open freely.
• The body support is intended exclusively for maintenance work.
• The technically permissible 11.000 kg applies only for on-site use, not on public roads.
• Retighten the wheel nuts after the first few hours of operation and regularly thereafter.

Frequently asked questions

Can I use it to transport construction machinery?

Yes. The 3.500 mm-long aluminium loading ramps are supplied as standard and stored between the running gear and load body. Eight lashing points inside the body secure the load.

How much can the trailer carry?

8.320 kg with a permissible gross weight of 9.000 kg. A technically permissible weight of 11.000 kg applies for on-site use.

Why are the ramps made from aluminium?

Steel ramps of this length are so heavy that two people are needed to hook them on. One person can handle the aluminium ramps alone.

Does the body tip?

Yes, backwards to 50°. The hydraulic tailgate opens at the same time; the tipping system has an automatic shut-off valve.

What is HARDOX and when is it worthwhile?

HARDOX 450HB is wear-resistant steel. The complete body is available in this material as optional equipment – ideal for businesses that mainly transport sharp-edged construction waste and recycling materials.

What tractor do I need?

62,6 PS or 46 kW and a hitch suitable for a 2.000 kg nose weight. Tipping requires 16 litres of oil at 200 bar.

Can I get more volume?

Yes, with the optional 800 mm extensions, complete with Plexiglas viewing window and rear swinging tailgate – making the trailer suitable for green waste and light bulk materials.

Why is the front wall rounded?

So that material slides out completely when tipping, rather than getting stuck in the corner. With damp soil and clay, it makes all the difference.
