COMPACT EQUIPMENT
Efficiency is key
The eight D Series rubber-tracked loader range in rated
operating capacity from1.2 tonnes to2.09 tonnes.
Mid-size frame models are the 257D multi terrain loader
(MTL) and259D compact track loader. Larger framemodels are
the 277D and287DMTLs and the 279D and289DCTLs.
These six models feature an electronically controlled 3.3-litre
engine complyingwithTier 4Final emissions standards.TheCat
C3.3B engine provides 74 hp (55 kW) with + 8%more torque
and+6% improved fuel economy compared topreviousmodels.
Also for the European andUSmarkets, Cat has released its D
series skid steer loaders –which have also undergone revisions to
the cab andperformance capabilities.
Liebherr has also placed strong emphasis on ensuring its latest
compact wheeled loaders – the L506 and 508 meet latest stage
IIIB/ Tier 4 engine specifications. According to the company,
thesemachines have been designedwith high all-round visibility
andmanoeuvrability.
With an operating weight of 5.1 tonnes and 5.6 tonnes
respectively, the L506 has a 46 kW engine, with its counterpart
508 model having a 50 kW engine. Their bucket capacities are
0.8m
3
and1m

for the higher specificationmachine.
JCB has extended and upgraded its compact articulated
wheeled loader range, with a thirdmodel and the introductionof
Tier 4 engines, offering increased torque and reduced emissions.
The company is adding a robust entry-levelmodel aimed at the
rentalmarket,while the engineupdateswill alsobe seenon JCB’s
TM180 andTM220 telescopic loader armmodels.
All threemachines are powered by a 2.5-litre engine developed
in partnershipwithKohler. Significantly, the have been designed
tooperatewithout the need for aDiesel Particulate Filter (DPF).
The 406 is now an entry-level model with a 50 hp (37 kW)
mechanical engine for the rental sector, while the 407 takes on
the role previously played by the 406, with a 64 hp (48 kW)
water-cooled electronically-controlled engine.The 409 is a 74hp
(55kW) version.
Though providing similar power outputs as the previous
machines, the 407 is +4% up on the old 406, the 407 benefits
from an +58% higher peak torque output, while the 409 gains a
+20% torque boost at a lower engine speedof 1,500 rpm.
A new range of compact wheeled loaders fromCase has been
developed complyingwithTier 4Final emissions requirements.
Comprising six newmachines, the company’s latest F-series of
models spans the 4.4 tonne 21F through to the largest loader, the
6.2 tonne 321F. They have been designed to offer increased lift
capacity of up to400kg each comparedwithpreviousmodels.
As completelynewmachines, the serieshashadamajor redesign
of cabins. The 21F and 121F are under 2.5 m high, aiding
transportationunder bridges if loadedon a truck.
Its FPT Industrial engines span from 58 to 74 hp (43 to 55
kW).They have been designed to operatewithout the need for a
particulate filter tomeet latest emissions standards.
Key features includeenhancedhydraulic systems,withhighflow
options available on the 221F and 321F.This enables the use of
power attachments including snowblowers and asphalt planers.
Compact excavators
Kubota in particular is targeting the two to three tonne weight
categorywith its latestmachine, theU27-4, which the company
says has delivered significant improvements over its previous
models.
The company claimed the equipment delivered among the
largest and well-equipped cabin in its class and have improved
safety and visibility formachine operators.
Kubota says itdeveloped its latest excavator tooperate ina range
of conditions with awell-balanced force allowing it todig swiftly
to a deeper level (2.8m) efficiently.
The U27-4’s engine has been built to exceed present European
emissions standards for the segment and is said tohave improved
fuel economy.
It has been developed for use in congested areas thanks to its
