Efficiency is key
technical innovations designed to improve work efficiency and
reduce operating costs.
It has been equippedwith anewdozer bladedesign tominimise
over-spill during levelling operations, reducing the work time
and fuel usually associatedwith levelling passes. It has a compact
short-tail with amaximumoverhang of just 190mm.
Hitachi has targeted high-performance for its latest mini
excavators, theZX17U-5 andZX19U-5.
Designed tobeuser-friendly,offeringhigh levelsofperformance,
comfort anddurability, the company said itsZaxis-5models have
been developed for narrow or confined spaces. Lightweight and
compact, these compact machines are said to be suitable for
utilities, foundationwork, landscaping and indoor demolition or
constructionprojects.

tracks.These can be retracted or widened
– depending on the requirements of the
job site – from 980 mm, for working in
small spaces or being loadedon to a truck,
to1,280mm for greater stability.

boom cylinder cover featuring two bolts
for addeddurability.
In addition, the rubber crawlers have
been upgraded and the undercover of
the revolving platform frame has been
lengthened. The design of both models
has changed to a revised D-frame to
enhance its performance.
Following the development of the SV26, Yanmar has launched
a new range of 1.5 to 2.5 tonnemini-excavators with ultra-short
rear swing radius.The new range includes the SV16, SV18 and
SV22, is said by the company to bemore powerful and easier to
use than the company’s previousmodels.
Someof theirkey features includecompactdimensions andvery
short rear overhang – inorder towork effectively in tight spaces.
All the machine’s operating movements are now joystick
controlled. Its instrument panel holds all control buttons,
including the blade control and the second-gear speed control.
The machines are fitted as standard with an LED light on the
lower part of the boom. Three additional lamps and a flashing
revolving light on the cab are optional.
US-basedmanufacturer Gehl has also released its latest mini-
excavator, the Z25, which delivers enhanced performance and
efficiency over the outgoingmodel, the Z27. Its mini excavators
are manufactured for the company by Yanmar, in the type of
OEM supply agreement that is becoming increasingly common
in the compact equipment sector.
Gehl said the machine had greater
efficiency through greater capability with
8 inches (203mm) deeper dig depth and
8.3 inches (211mm) and additional reach
at ground level compared to the previous
model.
Launched initiallywithin theUSmarket,
it is equipped with a 20.4 hp (15.2 kW)
electronically-controlled Yanmar Tier 4
emissions-certifieddiesel engine.
Creating an improved environment for
machine operators has been of central
importance, particularly with its joystick controls that reduce
operator fatigue through ease-of-use. The cab is fitted with a
4-way adjustable seat offering custom settings and optional
heaters are available.
The machines digital controls feature recordable maintenance
historywith adjustable time intervals and reminders, fluid levels,
fluid temperature, aswell as loggingmachine activity hours.
Featuring a Kubota V2607DI-T 2.6 litre four-cylinder engine,

It also has electronic selection of its three steering modes, with
a warning light on the dashboard enabling verification of the
correct alignment of thewheels of the rear axle.
It has been designed to work and drive easily in narrow places
withobstacle or corners.
The M-70W has a double effect power take off with max
delivery75 l/minat apressureof240bar andadditional hydraulic
pipes in order to use it as a multifunctional machine (roto-tilt,
grabbucket).
In addition to its largermodel, the companyhas also introduced
the 2.5 tonneM-25U zero swing mini-excavator.The company
said its fully servo-controlled systems during driving and have
resulted inbetter control andhighperformance.
Skid-steer

which it says has been developed to compete as among themost
productive anddurablemachines in its class.
Equippedwith a37hp (27.6-kW),Tier4Yanmardiesel engine,
