Kubota ubota introduces introduces new
new
mini mini excavators
excavators
The latest mini excavators to become
available from Kubota in Europe are the 4.8
tonne U48-4 zero tail swing and 5.6 tonne
U55-4 tight tail swing models. They join the
5.6 tonne conventional swing KX057-4
introduced in the autumn of last year.
All three excavators are powered by the
new Kubota V2607-DI direct injection, watercooled
diesel engine with auto-idling. The
power ratings are 28.8kW (40.5hp) for the
U48-4 and 33.8kW (46.0hp) for the U55-4 and KX057-4. The U48-4 has a one pump load sensing hydraulic system
whilst the two larger units have three pump load sensing systems.
Both the U series machines have an auto-shift travel system that automatically selects whichever of the two travel
speed ranges is better for each particular combination of tractive effort and terrain. There are also two auxiliary
hydraulic circuits on the M and L versions of the machines with the L version also having air conditioning.
Inside the new style larger cabs, the operators of the latest Kubota minis benefit from a new digital panel. Part of
Kubota’s Intelligent Control System, this user-friendly panel has a wider display to make it easier to read. Amongst
information that can be viewed is fuel level, engine temperature, service intervals, auxiliary circuit oil flow settings,
operational history and warning alerts.
Hillhead Hillhead debut debut for for latest latest Pioneer Pioneer Pump

The Hillhead Quarry Show was an apt event for Pioneer Pump to launch its new 100CH. This 150mm x 100mm
extreme pressure clear liquid pump is particularly suitable for high head water pumping in mines and quarries.
The 100CH on show was a fully bunded, skid-mounted unit with a sound attenuated canopy. The pump set has a
90-175kW (120-235hp) Perkins 1106D – E66TA engine and a vacuum assisted self-priming PP64C17 pump. The unit
has an 800 litre fuel tank and its nominal fuel consumption is between 17 to 65 litre/hr depending on application.
A maximum flow rate of 320m³/hr can be achieved by the 100CH and its maximum head capability is 155.0m. The
unit can handle solids of up to
20mm and its maximum efficiency
is 67%. Another 150mm x 100mm
Pioneer pump with high head
capability is the 100CX with a
Caterpillar C9ACERT engine.
The launch of the 100CH at
Hillhead follows the Bauma
introduction of the generalpurpose
100mm 100SL and
150SL sound attenuated, fully
bunded, Perkins engine driven
portable pump sets.
