ES2 and ES2 PLUS - Electronic Steering System

Management of steering axles and suspensions of a trailer

ES2 and ES2 PLUS manage the steering axles and suspensions of a trailer

We set out to create something that would be innovative, simple and improve the efficiency of commercially available trailers and semi-trailers while complying with road traffic regulations. A complete system, easy to install and quick to maintain.

The ES2 system allows, through the ISOBUS connection, to control the steering axles of a trailer. This greatly facilitates manoeuvres, especially in reverse, reducing the stresses to which the structure is subjected, fuel and tyre consumption, as well as trampling of the ground. The PLUS version, combined with the SIDRA hydraulic suspension, allows the user to vary the configuration of the vehicle, adapting its height to their needs.

Compatible with:

SIDRA system

One of the main systems on which the ES2 is installed is SIDRA hydraulic suspension, which enables steering controlled with the help of the ONE cylinder.

SIDRA is a modular hydraulic suspension with independent wheels that distributes the load on each wheel regardless of the formation of the ground.

Applicable on trailers with fixed axles, with forced steering and self-steering: SINGLE-AXLE, TANDEM, TRIDEM AND QUADRIEM (with 9 – 12 – 14-Ton capacities).

Compatible with:

Universal axle

Another of the main systems on which the ES2 is installed is the "UNIVERSAL" axle, designed to include all the functions inherent to steering in a single axle.

The axle is equipped with “ONE” cylinder that manages steering and a shock absorber that is always applied to eliminate “wobbling” during movement.
It is also equipped with an industrial steering bar with conical couplings that guarantees precise steering.

“ONE” cylinder

The ONE cylinder is a steering cylinder that is installed on the axles of SIDRA suspension and on "UNIVERSAL" axles.

It is called ONE because, depending on how it is connected to the hydraulic circuit, it can function in self-steering with a lock in the centre or as controlled steering.

Technical details

The user can manage operation of the steering axles at any time by choosing between: locked, floating or electronically controlled steering. The system also allows the lifting of one or more axles and the crab function.

The presence of SIDRA hydraulic suspension allows travel on particularly rough terrain while maintaining the same load on all axles. In addition, there is the possibility of having the automatic levelling function which, through an inclination sensor, always keeps the vehicle in a horizontal position.

ES2 and ES2 PLUS systems are widely used on various types of machinery, such as:

  • Dumper
  • Tanker
  • Flat bed
  • Other types of machinery
