As is customary during Eima Internationa, the Technical Innovations Contest was once again held at Eima Digital Preview 2020, organised by FederUnacoma to reward and promote the most innovative products offered by manufacturers in the sector.
Walvoil and Dieci have scooped both the prestigious Technical Innovation 2020-21 award and the Blue Award 2020-21 (dedicated to solutions that stand out in terms of environmental aspects) for having developed Adaptive Load Sensing (ALS), a system that minimises energy dispersion in the hydraulic system of telescopic handlers, considerably improving the vehicle’s efficiency and consequently achieving a reduction in wear and fuel consumption.
Walvoil, a historic brand in Emilia-Romagna’s hydraulic industry and now part of the Interpump Group, brings together the experience of the Hydrocontrol and Galtech brands, and has established itself as one of the world’s leading manufacturers of hydraulic, electronic and mechatronic products. Since 1982, Dieci has been a world leader in the design and construction of telescopic handlers, with a range of 110 models for agriculture, construction and heavy industry that are characterised by continuous innovation, thanks to constant research and the application of new solutions to meet market needs.
The innovation developed by the synergy between Walvoil and Dieci stems from an important consideration: hydraulic systems are an essential part of the most modern and widely used agricultural machinery. In these systems, to ensure simultaneous control of movements, the hydraulic pump generates a greater pressure than is really needed, a set value called the stand-by margin. This value accounts for a considerable loss of energy that limits the vehicle’s overall performance and unnecessarily increases wear and fuel consumption, thereby reducing efficiency and impacting the environment. In response to this problem, Walvoil devised Adaptive Load Sensing, a system capable of modulating the stand-by margin value depending on the vehicle’s actual work needs, automatically changing it only depending on when and how much power is required.
In partnership with Dieci, the ALS system was successfully tested on an AGRI PLUS 42.7 GD telehandler, one of the flagship vehicles in the Dieci range for Agriculture. During tests on the Agri Plus, the Walvoil-Dieci Technical Team detected a decrease in energy loss of 28% during boom operations and up to 45% during vehicle manoeuvres, with a noticeable performance improvement at various travel speeds. In addition, the tests highlighted further advantages, primarily in terms of safety: acting directly on the hydraulic signal, ALS avoids the functional complexity associated with the digital signal. Furthermore, in the event of faults, the original operation is automatically restored, avoiding vehicle downtime. Also in terms of stability: control of the pressure value enables the vehicle’s stability to be improved, resulting in greater comfort during use. And finally, in terms of modernisation: the ALS kit comprises only a small number of components, which can be easily installed even on older telehandlers, extending their operating life and improving their performance. More energy efficiency, more productivity, greater control, customisation potential, greater safety and stability, and the possibility of modernising older vehicles: all these are benefits of the Adaptive Load Sensing system, further proof of what can be achieved by the alliance of two outstanding companies, a partnership also validated by the prestigious awards obtained at EIMA 2020.
Profile of DIECI Srl
DIECI s.r.l. has been designing and manufacturing telehandlers since 1982. It boasts considerable experience in the construction and agriculture sector and is expanding its foothold in the markets, thanks to the company’s ability to understand and meet the diverse needs of its customers. The DIECI production is divided into 4 main categories: telehandlers (with fixed and rotating boom), truck mixers, dumpers and special-purpose machines. Currently, production is geared towards telehandlers: DIECI produces over 110 models combined with 30 chassis types, continuously offering the market new ideas and solutions for agriculture. Each vehicle is designed to best address the particular needs of the sector, thanks to materials, equipment, design features and accessories that are specific to each work situation. DIECI telescopic handlers have delivered excellent performance on public and private construction sites, in the construction of major engineering works, handling sizeable loads (such as shipping containers in port areas), and working inside marble quarries and on waste cycle-related activities. Drawing on over 30 years in the business, its extensive experience and the ability to interpret customers’ multi-faceted needs, DIECI continues to grow in Italy and is expanding into international markets. DIECI is engaged in the design, production and distribution of construction and agricultural vehicles, and in the last 10 years has established itself as one of the sector’s leading international players. The company’s international credentials can be summed up in one stat: in 2011, over 70% of DIECI vehicles produced were sold abroad.
After-sales service
Our after-sales service is a point of pride for DIECI. The maximum professionalism and efficiency stems from the rigorous training of internal staff, as well as our dealers and authorised workshops. DIECI organises an average of two training sessions per month: over a year, the company trains 200 people, of whom around 70% come from abroad. The after-sales service also takes care of technical assistance in every country where there is a DIECI vehicle: to its customers, the company provides maintenance, spare parts and specialised personnel in just 48 hours, thanks to an extensive and effective dealer network. In order to offer the best service possible, DIECI offers dealers incentives to create a warehouse stock programme, so that they can respond in a very short time to the most immediate needs of the customer.
