Design and components

Fifth wheel couplings from JOST – Trust the market leader

JOST filed a patent for their fifth wheel couplings Million of „JOST Fifth Wheels“ handle every
(JSK) made of cast steel in 1955 and received application all across the globe. Robust, reliable
general type approval in 1960. Since than fifth and versatile, proven and tested – no wonder
wheel couplings from JOST wrote their own that buyers and users from all over the world
success story. trust JOST. The right coupling for every need
can be found in the extensive range. Please
take a closer look at some of the specific
advantages here.

4
 1 Robust wear ring attached with 3 or 4 screws,
easy to repair: easy to replace from above

2 Recess on the patented lock jaw prevents

dangerous false locking

3 The adjusting screw allows the lock to be

subsequently adjusted, resulting in lower wear.

3 4 High quality ductile iron top plate

4
5 The guide bars in the insertion area ensure that
the king pin is guided accurately into the fifth
wheel coupling

6 The locking bar supported on both sides

guarantees an extremely stable safety system

7 Handle with latch for an optimum visibility of

locking state

Bearings

Rubber bearing – Model „C“

Fifth wheel couplings with rubber mountings
are particularly suitable for poor quality road
surfaces. The rubber cushions are shock-­ Shock-absorbent
absorbent and maintenance-free. rubber block
For series JSK37C and JSK38C

Slide bearing – Model „K“

The K-bearing moves especially easy and it is
torsion-proof and maintenance-free. It protects Collar
the chassis due to its longitudinal elasticity
(lateral movement) Rubber
For series JSK42K buffer

Pivot bearing – Model „D“ and „E“

The pivot bearing allows low mounting heights
and is maintenance-free in the “E” version. It is Collar
particularly suitable for use in sliding and dual
height fifth wheel systems. Rubber buffer
For series JSK36D and Slider

Cardan mounting – Model „G“

The cardanic bearing is designed to allow roll
between tractor and semi-trailer under off-road
conditions. Due to the high strains it is designed
as pivot bearing with wear-resistant bearing
bushings. The lateral suspension must be Wear-resistant
disabled for on-road use. bushings
For series JSK38G

Mounting

Plate mounting Fifth wheel coupling Mounting plate

The fifth wheel coupling is fixed to the SCANIA
tractor frame by means of a mounting plate.

Indispensable for construction sites, poor roads

and heavy-duty transport

For series JSK37C/JSK37CW, JSK36D, JSK37CX,

JSK38C, JSK38G Vehicle frame

Frame mounting Fifth wheel coupling

The fifth wheel coupling is built directly onto the without Mounting plate
frame of the SCANIA tractor.

This safes the the weight (40-60 kilograms) of

the mounting plate.

Particularly suitable for long distance

transportation, tank and silo vehicles, and all Vehicle frame
applications where low weight is a priority.

For series JSK42K7/JSK42K7W

Sensor coupling (3S)
A modern vehicle fleet places complex demands on operators and drivers. It is thus essential to make
it as safe as possible to operate the vehicle, to keep down the standing time and to avoid accidents.
A JOST sensor coupling that supports manual procedures can be received quickly and easily integrated
in the SCANIA dashboard when purchasing a new tractor.

1 A sensor permanently monitors the

connection status
2 A second sensor controls the position

of the king pin Now availa
3 An additional third sensor monitors the
contact locking position and displays it in
the driver’s cab

Maintenance level
Regular, thorough maintenance is the most important factor in ensuring a long life span for a fifth
wheel coupling. However, lubrication causes downtimes, costs money and harms the environment.
To improve the situation, there is a range of solutions that make lubrication easier or even entirely
unnecessary for a period of time.

Standard versions (Z)

All fifth wheel couplings in the version Z are prepared for connection to the central lubrication system
on the tractor unit.

Low-maintenance fifth wheel coupling (W)

The series JSK 37 CW / EW fifth wheel couplings or pivot bearing, only one greasing point on
and all the series JSK 42 fifth wheel couplings in the lock jaw needs local lubrication. All wearing
version “W” are equipped with a plastic top plate parts can be replaced quickly and easily. Low-
liner on the mounting surface and a wearing ring maintenance fifth wheel couplings therefore
with plastic insert in the locking mechanism. In save both time and money, as well as conserving
conjunction with the maintenance-free rubber resources.

1 Wear ring made from 2-component

2 polymer construction with optimum
1 sliding properties and strength
2 Robust screw connection with 4 screws
3
3 Maintenance-free plastic top liner made
of Polyethylene (PE)

LubeTronic 1Point versions (LT1P)

Low-maintenance fifth wheel couplings (Series W)
have to be lubricated on the lock jaw only.
The use of LubeTronic 1Point also eliminates
this manual procedure. After activation the
LubeTronic 1Point supplies the lock jaw with the
optimum amount of grease – guaranteed for
3 years. After this period, LubeTronic and the
lock jaw need to be replaced. LubeTronic 1Point
versions are available only on request.
