Fifth Wheel Couplings (Standard)
A fifth wheel coupling provides the link between a semi-trailer and a towing truck. Applications for fifth wheel couplings by JOST Australia include general, tipper, fridge, road train, highway, freight and tanker uses. Our fifth wheel couplings are an extremely reliable unit when maintained and serviced properly. Below is a list of fifth wheel couplings supplied by JOST Australia.
Proven Reliability: JOST’s standard fifth wheel couplings are built to last, with robust construction that withstands the stresses of daily transport operations. They are known for their reliability, providing peace of mind for fleet operators who need consistent performance.
Enhanced Safety Features: Safety is a top priority in our design process. Our fifth wheel couplings come equipped with features that minimise the risk of unintentional uncoupling and ensure secure connections every time.
Low Maintenance: Designed for ease of use, JOST fifth wheel couplings require minimal maintenance, reducing downtime and associated costs. This makes them a practical choice for fleets looking to optimise operational efficiency.
Versatility Across Applications: Whether you’re operating in long-haul transport, heavy-duty freight, or specialised applications, JOST’s standard fifth wheel couplings provide the versatility needed to handle various trailer types and loads.
