JOST (GB) of ileywood, Greater Manchester has developed a landing leg installation for semi-trailers equipped with air suspension.
If left for long periods the pressure in the suspension can reduce and cause the platform of the trailer to sink. This in turn can produce a bending moment in the landing legs of sufficient force to cause damage.
To compensate for the change in angle of the trailer platform, each leg strut can be fitted with a cylinder unit designed to allow sonic movement before the maximum permissible bending stress on the legs is reached.
The landing legs can pivot through three degrees about the connection shaft bearing.
Jost claims that the bearing and struts can be supplied separately, for the conversion of existing equipment, at a cost of about VI 5(1.
