1.3. DESIGN OF THE DEVICE
The Trailer is constructed out of cold hollow steel sections. Through this construction the
trailer receives maximum endurance and stiffness regarding both bending as well as twisting. The
trailer is steady both in the tip as well as in the changing movement. The trailer is equipped with a
spring suspension pendulum bogie that has been equipped with brakes on all wheels.

1.4.12. Frame locking
The hydraulic frame lock is used to lock the frame during the exchange function. The manometer is
present to indicate the tensile force on the cylinder. The manometer is set at 100 bar on delivery, but
can subsequently be adjusted either up or down according to the size of the tractor.

1.4.16. Brake system
The trailer is equipped with hydraulic brake system. Also is available pneumatic brake
system as an additional extra. The hydraulic pressure in the brake line is not allowed to raise over
16 Mpa. If using to high of a hydraulic pressure the tappet of the brake arm might go from centum
and lock the brakes.

1.5. SAFETY DEVICES
1.5.1. Security post
Always use the safety support when carrying out service work in the tipped position. The safety
support may not be used under any circumstances when the container bridge is loaded.
Figure 15. Security post
1.5.2. Location of the decals of the trailer
The trailer is equipped with a range of signs relating both to safety and information. Check that all
the signs are in the correct positions.

1.5.3. Presentation of decals
Figure 17. Warning triangle and instruction manual decal.
The trailer is supplied with a warning triangle alongside the instruction manual decal in
order to reinforce the requirement for the user to read the entire instruction manual carefully
before starting to use the trailer. Ignoring this can entail a danger to life.
Figure 18. Decal for the use of safety equipment.
These decals challenge the user to employ appropriate safety equipment in order to avoid
injury when using the trailer.
Figure 19. Risk of clamping injuries
There is a risk of clamping or crushing injuries during work and maintenance.
Figure 20. Hazardous area
Standing between the trailer and the towing vehicle when the trailer is being operated,
moved with frame steering or when other functions are activated between trailer and tractor,
can be potentially fatal. As the driver, you must always ensure that the area around the
machine is free of people.

Figure 21. Risk of slipping
There is a risk of slipping as the surfaces of the trailer can be slippery due to precipitation in
combination with pre-existing oil and/or clay on the surface. The ground around the trailer
can also become slippery, as the tyres can tear up the surface and expose clay and soil.
Figure 22. Hydraulic fluid under pressure
Hot hydraulic fluid at high pressure levels can occur in the hydraulic system. Take care
when connecting, and replace poor quality hoses.
Figure 23. Using the exchange unit
The exchange unit may not be operated unless the frame is folded down. During transport
with the trailer, the hook must be folded down in the parking position.

Figure 24. Use the safety support during all service
Leaning under the raised frame is absolutely prohibited unless it is blocked with
the safety support. Under no circumstances may the trailer be carrying either a
load or a container when using the safety support.
Figure 25. Max. load
It is absolutely prohibited to load more than the amount your model is intended to
handle. This can result in danger to you and your surroundings.
Figure 26. Max. pressure on towing eyelet
Ensure that you do not load in such a way that the pressure on the towing eyelet
exceeds the permitted laws and regulations. The trailer is designed for a
maximum pressure of 3,500 kg on the towing eyelet. The pressure is largely
determined by the way the load is distributed on the container bridge, and it is
the user’s responsibility to ensure that this is not exceeded.

Figure 27. Tyre inspection
The tyres must be tightened and the brakes checked regularly at a minimum interval of
40–50 kilometres.
