5 Sliders

Sliders allow the position of the fifth wheel coupling

to be moved on the semi-trailer tractor unit. This al-

lows the axle load and load distribution to be optimi-

sed, and the total length of the articulated vehicle to

be reduced for ferry crossings or adapted to comply

with national regulations.

JOST’s EV HD slider is suitable for use with heavy-

duty fifth wheel couplings of all conventional makes

with a connecting hole pattern in line with ISO 3842.

JOST’s EV MI slider is suitable for use with fifth

wheel couplings of all conventional makes with a

connecting hole pattern in line with ISO 3842.

The JSK SL sliders can be equipped as an option

with a pneumatic control and are supplied as a

complete unit with integrated fifth wheel coupling.

The SL series is outstanding as a result of its weight

and flexibility. All standard couplings (sheet steel

and cast) can be installed on it.

National regulations and JOST mounting instruc-

tions must be observed for their mounting.

Fitting sliders

The slider is mounted on the mounting angles of the tractorunit. There is no need for an additional mounting plate. Further details for fitting the slider are given in the mountinginstructions.
