TOP DRIVE SYSTEM air springs, applied on the rear axle interposed between the axle and chassis with the aim of minimise vibrations due to the impact of the end buffer, an unavoidable phenomenon when the vehicle is close to its load limit.
Hydrotech reinforced shock absorbers, specifically designed and manufactured for the’intensive use in vehicles approaching maximum payload. Perfectly interchangeable with the original shock absorbers, but with higher damping up to 30%.
The more than 1000 projects realised in just under 30 years and the more than 200,000 products sold represent the experiential basis adopted to satisfy every off-catalogue request.
Air suspension, shock absorbers, control systems, air distribution systems and much more are the core of the company's know-how.

It guarantees a increased vehicle comfort, together with a height adjustment system to cope with small gradients and rough terrain.
It provides for the’addition of two springs air in the front axle and a interconnected system of four springs air on the rear axle, in addition to the hydraulic shock absorbers not provided on the vehicle.
The support structures had to be entirely designed so that they could bear a load of approximately 4 tonnes at the rear and approximately 2 tonnes at the front. In addition, the mounting housings for the hydraulic shock absorbers were made on both the chassis and the axle.




System of air suspension 4-channel with integrated springs and dampers.
It allows the vehicle to be raised and lowered to dealing with different types of terrain.
The system consists of 6 electronically controlled coaxial spring/damping units.




A “model cell” was produced, the static and dynamic characteristics of which were studied and submitted to the customer for approval.
The CNR's motor institute in Naples needed a suspension platform that would make it possible to realise variable stiffnesses within a certain range of values, easily detachable and adjustable for air spring assemblies.
The special installation conditions led to a careful study of the fastening system to facilitate disassembly when replacing one or more components.
The control system was realised by grouping the air springs in groups of two with electropneumatic valves with differentiated loading and unloading, control gauges and switches to control the individual air spring assemblies integrated in the customer's control panel.
Feasibility study and prototyping for a angular pipe positioning system for air ducts for a customer producing pipes in 6 metre lengths.
Angular positioning was to be realised on a machine about 8 metres long, integrated with the upstream production plant and the downstream finished product handling.
Prototype realised using modular aluminium structures, linear sliding guides and PLC of control.
From a hybrid drive vehicle consisting of a rear suspension system with interlinked wheels intended for transporting people to the opening and closing ceremonies of the London 2012 Olympic Games, the suspension geometry had to be converted and a new one built to electronic control with kneeling function.
The entire system, from design to testing, was implemented and delivered in a few months across the entire fleet, an indication of the configuration flexibility offered by ECAS.
To facilitate the ascent and descent of people, the system had a kneeling function that allows only one side of the vehicle to be lowered to facilitate entry and the exit of passengers.

Year 2014, International Hannover Fair (IAA). Iveco Spa presented an experimental vehicle created on an Iveco Daily platform.
The vehicle had many innovative functions such as: hybrid propulsion (heat engine and electric motor), pressure intensity pedal, 360° vision system of the surrounding environment by means of high-definition cameras and was also equipped with an internal cargo locking system using adjustable air pockets.
The ESI Italia project, which was initially created to electronically control the front and rear air suspension, was extended to provide air and control to the load-lock system. All systems were electronically controlled and monitored via wireless connection with a tablet (iPad).
