H.T.S. Hydro Tech Systems S.r.l.

S.T. System Truck wasfounded in 2000 on the initiative of it’s three foundingmembers, each having gainedover twenty years experiencein the field of Industrial vehicle conversions. Theybegan production with a particular approach to the application of steering axleshydraulically controlled by a patented system called“TECHNOLOGY” and producedby a sister company calledH.T.S. Hydro TechSystems, founded in 2001 with the objective to design and produce innovative steering system solutions forindustrial vehicles. In 2007 H.T.S. Hydro Tech

Systems became a whollyowned subsidiary of S.T.System Truck with production facilities located in the samefactory. Today S.T. System Truck is the biggest converterof Industrial vehicles in Europe.

Company

HISTORY

To meet the needs of our customers with regardto modifications (below the chassis) of existingindustrial vehicles through:

• collecting & understanding the needs of the

customer / end-user;

• feasibility analysis (technical & regulatory);

• innovative design;

• installation at our facility, or

• on site training workshops for local installation of

customised kits;

• efficient aftersales service.

our

MISSION

• TRANSPARENCY

• LEGALITY

• PROFESSIONALISM

• SERVICE

our

PRINCIPALS

• Application of fixed, self-steered or full

command hydraulically steered axles, central or rear;

• application of axles with hydraulic assist

mechanical steering on three axle vehicles tobuild four axle chassis which can achieve a GVW of 32 ton;

• application and/or supply of complete

systems (hydraulic, pneumatic, electrical) forvehicles already in circulation;

• industrial vehicles wheelbase modification –

lengthening or shortening;

• lowering chassis (suspension modification

from mechanical to pneumatic or mixed);

• repackaging of chassis auxiliary groups

(tanks, batteries..) to meet customer and bodybuilder needs.

For certain types of conversions installationkits are available, complete with service manualand spare parts catalogue.

PRODUCTS

Our ability to design, produce and our commercial attention to the positive response to the needs of the customer, have enabled the rapid growth of the company, from the initial production area of 900 m2, to a new facility with a total area of 6500 m2 (3200 m2 covered).

This growth was made possible mainly by expanding our market, which since 2002 is no longer just national but now covers all of Europe and some Asian countries.

In recent years the turnover has stabilized at € 5 Million and production capacity has increased to 500 vehicles per year and while processing in excess of 150 conversion kits.

A RAPID CLIMB

Despite the crisis in the industry, we have maintained our targets due to the flexibility and capability of our technical service, which has always distinguished us.

Our vehicles conversions and / or steering systems are present on all major European markets:

and since 2012 also in South Africa and China.

Collaboration with the major industrial vehicle constructorsstarted:

• in 2001 with Iveco (Italy)

• in 2003 with Volvo (Italy)

• in 2004 with Renault (Italy)

• in 2006 with Renault (France)

• in 2008 with Volvo (UK)

• in 2009 with Volvo (Svezia)

since 2007

since 2010

All conversion solutions are engineered by the technical office: all suspension, axles, steering systems, pneumatic and electrical systems etc.. satisfy all OEM requirements and are in line with current legislation (national and European).

The technical department uses 3D CAD (Solid Works) for the design and verification for structural finite element analysis (FEA). Critical components are analysed in

order to reduce the risks of malfunction during operation, for design errors or for deficiencies in the production process, by means of FMEA (Failure Mode, Effect Analysis), especially in the case of new products or changes to products and / or existing processes.

DESIGN & DEVELOPMENT

The design process also includes the following steps of monitoring:• verification of the project inputs,• review of project inputs,• start design planning review,• review of design for development,• review of final design,• validation of the design.

• its movement is synchronized with the front axle and it improves the handling of the vehicle in forward

and reverse directions. It also improves the driving capability in every operational situation, reduces tyrewear and road damage, reduces fuel consumption and stress loading on the chassis while turning;

• the steering and the memory of the angular position of the axle is ensured by a flexible command cable,

which translates exactly the angular movement of the front axle;

• the heart of the system is the hydraulic circuit. This is the circuit of the power steering. The circuit is

powered by a pump added independently and driven by the vehicle engine;

• the original front axle power-assist is not effected in any way or influenced by the steering application, nor

is the electronic system of the vehicle changed in any way;

• the pneumatic circuit ensures self-centering of the system "TECHNOLOGY“ and therefore the axle in the

event of a hydraulic pressure loss. This circuit is connected to the pneumatic original on the vehicle.

CHASSIS CONVERSIONS

The production processes are carried out by qualified and experienced personnel.For the system manufacture we

employ specialist technicians, who are regularly trained and updated (licensed for welding EN 287-1) and certified processes (UNI EN ISO 9001 and UNI EN ISO 15614:1 for welding). Equipment and measuring

instruments (torque wrenches, torque controlled screwdrivers, etc..) are periodically inspected and calibrated. A Josam laser device is used for axle alignment on each vehicle before delivery, in order to ensure the correct alignment of the axes. A spray booth which can contain

vehicles in length up to 12 m is used for finish painting.

S.T. System Truck transformed it’s first vehicle in the year October 2000: a 440E42T IVECO Magirus-3.5, tractor unit with application of a third rear-steer axle.It has exceeded 5000 conversions at the

facility in Verona (up to 2011).To date, there are more than 5500

vehicles operating all across Europe which utilise the “TECHNOLOGY” hydraulic steering system.

The company is qualified by the major vehicle manufacturers for the supply as the primary system,and the Ministry of Transport for the conformity of series production (CoP).The vehicles are regularly tested at

the Ministry of Transport with the performance of all required tests (braking, ABS, steering, etc..). S.T. System Truck is able to deal

with the practice of testing, both for vehicles for the domestic market, which in the foreign market, by the issuance of the Certificate of Approval IVA (for vehicles approved in a single copy) or COC (for approved vehicles with mass production).
