TRIDEC BTRG Mechanical Steering System

Mechanical
Rigid Axle

Mechanical steering designed for silo and bulk trailers
Steers 1 or 2 axles on a 1- to 3-axle trailer
Robust enough for light off-road use, such as remote farms
Steering rods alongside the tank — no tank volume compromised
10 t axle load; 15 / 20 t fifth wheel load; 1,300 mm spring centre
Progressive steering with angles up to 35°

Built for Silo and Bulk Trailers

The mechanical BTRG steering system is specially designed for silo and bulk trailers. The simple steering system is very robust, making it fit for light off-road situations such as on route or at a remote farm. It steers one or two axles, possibly in combination with one or more rigid axles.

Silo and bulk trailers
One or two steered axles, optionally with rigid axles
Light off-road use, on route or at a remote farm
Urban roads, small roundabouts, farms and construction sites

Designed for Better Manoeuvrability

Superior manoeuvrability for bulk transport

Progressive steering makes the trailer very agile
Steers 1 or 2 axles on a 1- to 3-axle trailer
Steering angles up to 35°
Easy negotiation of urban roads, small roundabouts, farms and construction sites
Steering rods alongside the tank, not compromising valuable tank volume

Lower operating costs

Time through better manoeuvrability
Fuel consumption
Tyre wear
Vehicle maintenance
Vehicle damage

Robust, direct mechanical steering

Motion via the fifth wheel plate and TRIDEC steering wedge
Two steering rods transmit the motion to the rear axle mounting frame
A third steering rod transmits the motion to the other axle when two are steered
Fifth wheel loads 15 / 20 t; 10 t axle load (legally approved)
RDW test report per EEC 70/311 for 1–2 steered axles (no. 56210001)
JOST turntable with TRIDEC spline bolts — no re-tightening required
Maintenance-free ball joints; galvanised steering rods

Flexible fit and easy installation

Fifth wheel unit bolted onto the chassis for simple, quick installation
Wings with and without offset, in several lengths and widths to set the optimal steering angle
Axle mounting frame for 1,300 mm spring centre; height 140 mm (optionally 100 mm)
JOST turntable Ø1,200 or 1,300 mm; centralised greasing block
Several hoops for different tyre sizes and ride heights
Gross weight 1,029 kg (1 axle) / 1,365 kg (2 axles); KTL-treated
