THE TRIMBLE TSC3 handheld controller for construction is said to offer powerful and rugged control capabilities. This hand-held unit is aimed at duties with heavy and highway contractors and features builtin GPS, 3G, Wi-Fi and a 5 megapixel digital camera. The unit is said to allow site workers to stay connected and also provides accurate positioning and digital design information. Using this unit allows engineers to locate, measure and record information anywhere on the construction site with a single devi

One of the most notable developments in the loading and hauling sector though again comes from Liebherr, with the long awaited launch of its ADT range.

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.

Danish company DELTA has unveiled its new LTL-M mobile retroreflectometer, which it says has taken about four years to develop. The unit, seen at the recent Traffex show in Birmingham, UK, measures all types of road markings at a simulated distance of 30m "with the highest level of accuracy." The company says that the LTL-M is to be used mounted on a vehicle measuring retroreflection at normal traffic speed providing full overview of the condition of the road markings. DELTA says the instrument operat

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
