The LX2 elec­tric wheel loader is a sec­ond­gen­er­a­tion pro­to­type that is part of a re­search project and is not com­mer­cially avail­able.

To make the ma­chine elec­tric, the com­bus­tion en­gine has been re­placed with a lithium ion bat­tery. This stores enough elec­tric en­ergy to op­er­ate the ma­chine for eight hours in its most com­mon ap­pli­ca­tions, such as light in­fra­struc­ture con­struc­tion and land­scap­ing. The LX2 also in­cor­po­rates two ded­i­cated elec­tric mo­tors, one for the driv­e­train and one for the hy­draulics.

De­cou­pling the sub­sys­tems has led to higher ef­fi­ciency in both the sys­tems and the en­tire ma­chine, says Volvo.

“The LX2 is a rev­o­lu­tion­ary zero-emis­sions pro­to­type that of­fers im­proved ef­fi­ciency and lower op­er­a­tional costs, without com­pro­mis­ing on ma­chine per­for­mance,” Volvo emerg­ing tech­nolo­gies man­ager Ul­rich Faß says. “It in­cor­po­rates the lat­est ad­vanced chem­istry bat­tery tech­nol­ogy. As it’s elec­tric, no par­tic­u­late mat­ter, ni­tro­gen ox­ide or car­bon diox­ide are re­leased into the en­vi­ron­ment.”

This, to­gether with the fact that it has ex­tremely low noise lev­els, makes it ideal for use in cities and densely pop­u­lated ar­eas, as it can be used without dis­turb­ing peo­ple, says Volvo.

“This is the same for the EX2 100 per cent elec­tric com­pact ex­ca­va­tor, there­fore the ma­chines would be ideally suited to work­ing along­side each other,” adds Faß.

Like the LX2, the EX2 is also part of a re­search project and is not com­mer­cially avail­able. The com­pany says that the pro­to­type ma­chine de­liv­ers zero emis­sions, 10 times higher ef­fi­ciency, 10 times lower noise lev­els and re­duced to­tal cost of own­er­ship com­pared to its con­ven­tional coun­ter­parts.

At the sum­mit, Volvo CE also pre­sented its elec­tric site re­search project, which aims to trans­form the quarry and ag­gre­gates in­dus­try by re­duc­ing car­bon emis­sions by up to 95 per cent and to­tal cost of own­er­ship by up to 25 per cent.

Volvo CE and its cus­tomer Skan­ska Swe­den are cur­rently test­ing the elec­tric site so­lu­tion in a real pro­duc­tion en­vi­ron­ment for 10 weeks at Skan­ska’s Vikan Kross quarry, near

Gothen­burg, Swe­den.

The sys­tem in­cor­po­rates pro­to­type elec­tric and au­ton­o­mous ma­chines, in­clud­ing the HX2 au­ton­o­mous bat­tery-elec­tric load car­rier, the LX1 hy­brid wheel loader and the EX1 ca­ble-con­nected ex­ca­va­tor. These ma­chines are part of a re­search project and are not com­mer­cially avail­able.

“The elec­tri­fi­ca­tion of con­struc­tion equip­ment will pro­duce cleaner, qui­eter and more ef­fi­cient ma­chines – this rep­re­sents the fu­ture of our in­dus­try,” Volvo CE se­nior vice pres­i­dent of tech­nol­ogy Pa­trik Lund­blad says. “We are cur­rently in a pe­riod of ex­po­nen­tial tech­nol­ogy growth and are at the start of a paradigm shift.

“At Volvo CE we are de­vel­op­ing tech­nolo­gies con­nected to elec­tro­mo­bil­ity, au­to­ma­tion and con­nec­tiv­ity that will ben­e­fit our cus­tomers and the en­vi­ron­ment by con­tribut­ing to in­creased ma­chine per­for­mance, pro­duc­tiv­ity, ef­fi­ciency, safety and sus­tain­abil­ity. Our fu­ture prod­ucts and ser­vices will play an im­por­tant part in build­ing a sus­tain­able so­ci­ety.”

Ex­tremely low noise lev­els makes it ideal for use in cities and densely pop­u­lated ar­eas.
