Sliders allow the position of the fifth wheel coupling to be moved on the semi-trailer tractor unit. This allows the axle load and load distribution to be optimised, and the total length of the articulated vehicle to be reduced for ferry crossings or adapted to comply with national regulations.
The new ProTech Slider for standard fifth wheel coupling offers an enormous weight advantage of up to 25 kg in comparison to similar sliders. The ProTech Slider is also suitable for wide chassis hole patterns.
The JSK SL and ProTech sliders can be equipped as an option with a pneumatic control and are supplied as a complete unit with integrated fifth wheel coupling.
The JOST’s EV HD slider is suitable for use with heavyduty fifth wheel couplings of all conventional makes with a connecting hole pattern in line with ISO 3842.
National regulations and JOST mounting instructions must be observed for their mounting (on www.jost-world.com).
The slider is mounted on the mounting angles of the tractor unit. There is no need for an additional mounting plate. Further details for fitting the slider are given in the mounting instructions.
