Volvo Construction Equipment says that its all-new F-Series ADTs will meet the tough Tier 4 Interim/Stage IIIB emissions legislation as well as delivering performance improvements over previous models.

With the Tier 4 interim/Stage IIIB emissions requirements due next year, further upgrades will be required for all wheeled loaders sold in Europe and North America.

The introduction of the latest emissions standards in North America and Europe are requiring major design rethinks for earthmoving machines such as ADTs, Mike Woof reports. With the introduction of the Tier 4 Interim/Stage IIIB emissions legislation, major changes are being made to off-highway machines. One of the machine types most affected by this legislation will be the articulated dump truck (ADT) and designers have faced major challenges in developing solutions that retain what are now seen as key oper

In the earthmoving sector, much development is being seen in excavators and wheeled loaders used for digging and loading, Mike Woof reports

Although construction projects in Dubai and Abu Dhabi demand large volumes of aggregates, many quarries in those regions are being closed by authorities. Much of the demand is being met by quarries in the Emirate of Fujairah which are fast becoming the regions' 'bread basket' for gabbro aggregates.

Dealing with nuisance dust is an issue for almost every quarry and for those operating in the tropical paradise of the Caribbean, it is no different. One Trinidad-based quarry operator has recently tackled the problem and is seeing benefits for its workers, neighbours and its machine service life too.

Caterpillar's new 390DL excavator is said to delivers higher performance and increased durability over the 385C model it replaces. Power comes from an 18.1litre Cat C18 ACERT diesel, which delivers 390kW and features advanced electronic control, precise fuel delivery and refined air management. Upgrades to the 390DL's implement hydraulics allow the excavator to deliver greater digging and lifting forces than its predecessor. Increased breakout force promotes faster trenching and loading cycles plus stronger

Case Construction Equipment introduces three new F Series wheel loaders to European customers, which are said to offer faster acceleration, reduced cycle times, higher travel speeds, increased productivity and up to a 10% reduction in fuel consumption.

Russian construction equipment manufacturer CHETRA, part of Machinery and Industrial Group (M&IG), has unveiled ambitious plans to establish a production unit in India.

New Holland Construction launched the first two models of its new C Series range of crawler excavators at the recent Samoter event in Italy. With operating weights ranging from 27-31tonnes, the new E265C and E305C models introduce new features that that are said to improve productivity and performance, and these include Tier 4 interim engines delivering more power and up to 10% improvement in fuel efficiency; high efficiency hydraulic system to increase productivity by up to 10%; EVO cab with ROPS/FOPS prot
