SHT: The hybrid system for cranes up to 40 tm
The Smart Hybrid Technology (SHT) system allows a wide range of cranes (from Micro models to models with a 40-tm lifting capacity) to operate in a fully electrical mode without emissions from exhaust gas but also without noise emissions. Thanks to the SHT system, the crane operates with the truck engine switched off, driven by its electric motor, which is powered by the battery pack. This is a solution that is also safe, as it operates at a low voltage (48V-51V) and therefore does not require any special operator training, as would be necessary with medium-high voltage systems. The dual charging system uses 220V single-phase 16A mains electricity, with a recharging time of nine hours if the batteries are completely discharged, which is unlikely as the batteries are normally recharged by the truck's engine while on the move, meaning that by the evening when the vehicle returns to its home base, the recharging process has already partially taken place. Moreover, this operation can also be carried out with the crane at work and the AC generator in operation. The latter, via the vehicle's PTO (which can be disconnected), recharges the batteries when the vehicle is in motion. Its recharging voltage is 48V and can recharge a fully exhausted battery pack in 4-5 hours.
In terms of flexibility, operational costs, and sustainability, and therefore in operational terms, using the SHT system allows the operator to work in areas characterised by limitations on the emission of both pollutants and noise, such as historic urban centres and lifting in enclosed spaces. Furthermore, the application of this sustainable electric solution has absolutely no negative impact on functionality; the crane can operate in electric mode for up to three hours offering the same levels of performance.
Plug-In: The system that extends the range of zero-emission solutions
The plug-In system allows cranes from 40 tm to 90 tm to operate whilst connected to a mains power supply. The system is made up of a three-phase power pack that is integrated into the set-up, positioned to the side of the truck and connected whenever electric mode is required.
The Plug-In system can be used by operators handling machinery in enclosed spaces, and for those looking to work with mains power. This solution bridges the gap between a hybrid vehicle and a full-electric vehicle. The advantages are two-fold; the first is of an economic nature, as the system has an attractive price, and the second concerns the possibility for cranes up to 90 tm to operate in electric mode, with the only limitation being the need for a mains electricity connection, unlike the SHT system which - as it has its own battery - is completely independent.
Fassi and Volvo Trucks present first “full electric” truck-crane combination
The pairing is comprised of a Fassi F195A.1.25 xe-dynamic and a Volvo FE truck. Not only is the set-up fully electric, but it also offers the advantage of allowing the crane and vehicle to intercommunicate via the Fassi FX-Link system. The truck has its own software that manages motor power, and with the Fassi FX-Link, the two machines exchange information in order to optimise operations. For this set-up, a short-wheel-base version of the Volvo FE has been used, with a configuration suited to situations that favour the “full-electric” solution, such as urban centres and enclosed spaces.
The Fassi F195.1.25 xe-dynamic has a capacity class with a maximum moment of 19.20 tm/188 kNm and a maximum hydraulic outreach of 14.70 m. The Volvo FE has been designed for medium-weight loads, with a GVW of 27 t and a 400-kW drive offering a maximum torque of 530 Nm for an autonomy of up to 200 km, with a charge time ranging from under 2 hours to 11 hours according to mode. The capacity of the batteries varies from 200 to 265 kWh, with packs of either 3 or 4 batteries.
Volvo also offers the flagship FH Electric model in either 8x2 or 8x4 versions with a GVW of 44 tons, which is ideal for the fitting of larger knuckle-boom cranes; on this model, power is provided by two or three electric motors offering up to 490 kWh (666 hp), completed with the i-Shift gearbox.
World preview of Fassi XR310: the new series of single-boom cranes for South-East Asian market
The Fassi XR310 made its world debut at Bauma together with the XR710, a single-boom model with a maximum lifting capacity of 7 tons, both made in collaboration with South-East Asian importers and clients. The two series have been designed specifically for this geographic area and, more generally, for international markets where demand for this type of crane is high. The aim is to develop a range of single-boom cranes, products that are significantly different from the cranes that Fassi has produced up to now.
