What's New in Plant & Equipment

Caterpillar says that there is no difference to perfor-

mance when running either the diesel engine or via the

power pack. Net power is 9.6 kW and bucket force

8.9 kN for the 1,088 kg.

Although manufactured by Wacker Neuson, warran-

ty, support and parts are via the Caterpillar dealer

network.

Within the Wacker Neuson product range, the equiv-

alent model is the 803 dual power conventional tracked

excavator.

Alternatives to

Conventional Excavators

Over the years, much has been written about the need

to reduce emissions. This has been mainly focused on

improving diesel engine technology to clean emissions.

However, there have been advances in parallel technol-

ogy such as hybrid, batter, or electric powered

equipment.

This is most evident in the smaller, compact equip-

ment sector where such equipment is often a viable tool

in internal or underground projects where emissions are

not allowed or are expensive to minimise through ven-

tilation, etc.

Two Electrics from IHI

The Japanese equipment manufacturer,

IHI Construction

Equipment

, is one of the leaders in compact excavators.

Within their range are two electric powered models - the

9VXE-3 9VXE-3 and the 17VXE elect r i c

mini-excavators.

Both model come standard with all the features

of the diesel powered models but also allows exca-

vating in confined areas with fume regulations.

Combine a no emission motor with other standard

features such as the ability to change front end at-

tachments hydraulic piping to front of the unit and

you have total flexibility within the confines of the

30.5 m (100 ft) power cord.

Although this does restrict working area, being mains

power the excavators can work continuously.

Excavators

Over recent years, companies have

introduced variations to standard

compact excavators to be powered by

electricity - either using a power cord

(with its restrictions) or by battery

(which has a working limit).

The USA company,

CB Electric

Excavator

is carving out a niche for
