French OEM Manitou Group is including to its vary of electrical telehandlers with a zero-emission model of one among its best-selling diesel autos for agriculture. Right here we get a primary take a look at the machine and discover out extra in regards to the pondering behind its progressive powertrain
Manitou Group is continuous the drive in direction of electrifying the off-highway sector with its model new MLT 625e, its first battery electrical fastened telehandler for the agricultural sector.
The automobile, which is predicated on the MLT 625 H diesel equal, is powered by a lithium-ion battery accompanied by two electrical motors. The agricultural model has a 9kW built-in battery charger as customary which implies quick charging is extra simply achieved than earlier electrical fashions. Like its diesel counterpart, the MLT 625e is effectively tailored to the agricultural trade with an oscillating rear axle, agricultural tyres, a excessive floor clearance of 38cm and 4 wheel drive. It additionally comes with a full vary of ag attachments together with a bucket, grapple bucket, large bag handler, sweeper and bale clamp.
This progressive automobile provides additional advantages for farmers, with zero fumes making it very best for work in shut proximity with animals and different employees. The low noise additionally minimises disruption. When the Group seemed on the design of the MLT 625e, it concerned rather more than simply merely swapping the engine for a battery pack. Probably the most progressive options is the central positioning of the battery pack, which not solely protects the battery from potential injury throughout operation, but additionally enhances the machine’s stability by centralising the burden which is essential throughout lifting operations.
Reasonably than merely retrofitting an present diesel mannequin, Manitou redesigned the chassis to accommodate the battery pack. This ground-up strategy to design ensures the electrical telehandler can totally capitalise on the advantages of its energy supply.
On the core of the MLT 625e is a lithium-ion battery which is designed to offer 4 hours of steady work time. The machine’s energy administration system always screens and adjusts output to maximise effectivity and battery life.
“Within the diesel model, we had the hydraulic pump mounted straight on the engine itself so the engine was at all times operating,” says Damien Rolland, head of the engineering division on the tremendous compact telehandlers product unit. “Within the electrical model, we now have a devoted motor for the hydraulic system. Which means when the operator will not be requesting something, the machine doesn’t run.”
“When hydraulic motion is required, the electrical motor begins operating and it’s linked on to the operator’s wants. For instance, when the operator desires to make a sluggish motion, the motor runs slower and when the person wants full energy, the motor will function at prime velocity. The vitality consumption actually is determined by the operator’s requests.”
Battery recharging is assisted by the on-board 9kW charger, which implies the machine may be totally charged in round three hours utilizing a 380V plug. For added comfort, the telehandler comes outfitted with adapters for each 380V and 220V plugs, making certain compatibility with numerous farm setups.
The fast-charging functionality reduces downtime and will increase total productiveness. The pliability in charging additionally permits farmers to combine the MLT 625e seamlessly into their day by day operations with out the necessity for main infrastructure adjustments. “Alternative charging means we are able to cost the machine at any time when we wish and it additionally signifies that we shouldn’t have to completely cost the machine every time,” says Camille Rouvrais, a product supervisor at Manitou Group. “There isn’t a particular charging room wanted or extra upkeep.”
“We have now a devoted motor for the hydraulic system. Which means when the operator will not be requesting something, the machine doesn’t run”
The MLT 625e has been designed to match the capabilities of its diesel counterpart with a lifting capability of two,500kg and most lifting top of 5.9m, in addition to its total hydraulic efficiency.
“In comparison with the diesel model, the traction energy is barely diminished,” says Rolland. “However, the electrical model is rather more reactive, so we don’t really feel we now have a big lack of energy. The facility is greater than sufficient for agricultural functions.”
Security options
The MLT 625e incorporates superior options to guard each the operator and the machine. The combination of a battery administration system (BMS) is on the coronary heart of those security measures.
The true-time communication between the BMS and the machine’s central management system makes energy output changes primarily based on battery circumstances and operator calls for. If the battery cost is low or if temperature circumstances are suboptimal, the system can restrict energy output to forestall injury and guarantee continued operation.
“The BMS sends data to the machine’s system. The system then assesses the operator’s request and the battery capability and adapts the request accordingly. If the request is in stability with the battery capability, the motion shall be as requested. If the battery can not ship the facility wanted, the motion shall be diminished,” says Rolland.
The MLT 625e additionally options thermal administration methods to keep up optimum battery temperature. A small radiator and fan system assist regulate the temperature of the traction motor and hydraulic oil, whereas additionally offering cooling for electrical elements within the automobile.
“Alternative charging means we are able to cost the machine at any time when we wish and shouldn’t have to completely cost it every time”
Moreover, Manitou Group has carried out measures to guard {the electrical} elements from mud, particles and moisture which might doubtlessly trigger put on and injury and are fixed hazards in agricultural. “All {the electrical} elements have an IP65 ranking and most of them are positioned underneath the engine bonnet to guard them from rain, filth, mud and particles. We have now additionally designed a canopy for
the motor which provides safety in opposition to adversarial climate circumstances,” says Rolland.
The electrical powertrain within the MLT 625e means a lot much less upkeep is required when in comparison with a conventional diesel machine, without having for engine oil adjustments or gasoline filter replacements. This not solely reduces downtime, but additionally lowers the overall price of possession
for the farmers.
The change to electrical has resulted in a considerably quieter operation. This discount in noise makes the telehandler well-suited for indoor operations, equivalent to in barns or different enclosed agricultural areas.
The introduction of the MLT 625e aligns with Manitou Group’s goal to have 43% of its product vary bought as low emission by 2030. “By way of sustainability, we’re already making strikes within the building sector, and we purpose to do precisely the identical within the agricultural sector,” says Franck Lethorey, who’s exterior communication supervisor for the Manitou Group. “We have now a devoted low-carbon pathway which has been validated by the SBTI organisation. It’s actually essential for us to speed up the deployment of our electrical ranges and we’re presently within the technique of engaged on hydrogen prototypes. We even have a well-established CSR coverage. This can be our first agricultural telehandler launch, however we’re centered on our whole world technique.”
