Other electric concept mini excavators were unveiled by Hitachi and Kobelco. The former showed a 1.9-tonne ZE19 mini (being developed in conjunction with KTEG), whilst the latter highlighted a 1.7-tonne 17SR electric mini, which is the result of a collaboration with engine maker Deutz.
Two new environmentally-friendly compact machines were prominent on the Kubota stand. These included a prototype 1,755kg KX019-4 LPG-powered mini excavator and a 700kg-capacity KC70-4e electric mini crawler dumper (which is a badge-engineered Hinowa product). Both these machines will be first shown in the UK at Plantworx.
Small dumpers
Morooka unveiled this concept electric version of its rotating- top MST-200VDR tracked carrier.
More small electric dumpers were also in evidence. Ausa showed its prototype 1.0-tonne payload D100AHA wheeled site
dumper that is being tested on-site in Paris and is likely to go into production next year. And Morooka unveiled an interesting version of its small rotating-top MST-200VDR tracked carrier. Brought into Europe especially for Bauma, the concept electric version of this small 2,000kg-payload Morooka tracked carrier is equipped with 29kWh Lithium-ion batteries. The machine on show had a guidance track on the ground designed for use on sites with a regular haul route.
In the past, site dumpers with the operator behind the skip have moved up in size to compete against the smallest articulated dump trucks (ADTs), such as the 10-tonne payload Hydrema 912. Now this Danish company has moved the ADT concept down in size with the Bauma launch of the new 6.5-tonne payload 707G.
Developed to capitalise on the move towards dumpers with better forward visibility, the 707G ADT has a front-mounted cab with forward- facing seat and controls. Set to have its UK launch at Plantworx, this newcomer has a Stage V emissions-compliant Cummins F3.8 engine and a Sauer Danfoss hydrostatic transmission. It features a low, easy-entry cab, a low centre of gravity and the ability to ride on 700/40x22.5 low ground pressure tyres to facilitate operation on boggy terrain.
Electric drive is starting to find its way into small telescopic handlers and, at Bauma, Manitou revealed a prototype electric version of its popular MT625. With a maximum capacity of 2,500kg and a 5.85m maximum lift height, the ‘Oxygen Concept’ compact MT625e gains intuitive operator aids, while greater use has been made of natural, sustainable materials such as wood inside the cab. Said to provide plenty of torque, the MT625e is now undertaking an extensive series of site trials.
Other small telescopic handlers with the latest low emission diesel engines were shown at Bauma by Dieci, Genie and Tobroco-GiANT. Of particular interest was the unveiling of what will become Dieci’s smallest model. Slotting in under the existing Apollo 26.6, the forthcoming Apollo 20.4 will provide a maximum capacity of 2,000kg and a maximum lift height of 4.32m.
The new 6.5-tonne payload Hydrema 707G ADT provides a competitor to similarly sized site dumpers.

Having previously pioneered the introduction of three-wheeled electric mini dumpers, Ecovolve from Ireland unveiled its new EL500 battery-powered mini loader at Bauma. This 978mm-wide machine weighs 1,300kg and has a maximum safe load of 500kg. All its three wheels are driven and steering achieved using the tiller control on the rear wheel.
