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 strong pendulum bogie that has

been equipped with brakes on all wheels.
