A new generation of asphalt compaction technology is coming to market, reports Mike Woof. The market for rubber tyred compactors has grown in recent years, prompting manufacturers to develop a new generation of machines.

Earthmoving machines remain the backbone of construction operations - writes Mike Woof. ADTs, excavators and wheeled loaders play pivotal roles in most construction jobs with the earthmoving stage providing a key component of most projects.

Montabert is now offering an innovative technology on its new V4500 breaker that offers automatic speed selection. The V4500 hydraulic breaker can be mounted on excavators from 45-80tonnes and is said to offer high productivity, reliability and durability, a high power to weight ratio, easy maintenance, a long life span and a high resale value. Weighing in at 4.5tonnes with top bracket and tool the V4500 works with a maximum input power of 117kW, a hydraulic flow of 380 litres/min and delivers a frequency o

Allen Engineering has developed its new E-Screed for use in confined pour areas. This unit is driven by a high-frequency electric motor that is said to be reliable and durable, with power from a re-chargeable, high-performance 36V battery that can be replaced on-site. The no-maintenance motor is precisely regulated with a variable speed controller and the battery delivers charge-anytime performance over 1500+ life cycles.

Leica Geosystems says that sophisticated PowerDigger 2D guidance system for excavators offers automatic slope control. The system expands on its PowerSnap technology and is said to make excavating easier and more productive. The system uses a standard panel whether fitted to a dozer, excavator or grader, which is also said to save money on training and equipment, as well as reducing down time. Leica PowerDigger 2D system allows multiple elevations and slopes to be constructed at any orientation, witho

Komatsu is rolling out its new PC190-8 excavator, which replaces the previous PC180-7 model. The new machine weighs in at up to 20tonnes and features an engine power increase of 7% over the previous model, boosting performance and productivity. Digging output is increased due to features such as a 200mm longer monoboom, and a maximum bucket capacity of 1.14m3. Lifting capacity is increased and the PC190-8 lifts over a tonne more than the PC180-7, while it offers a bucket digging force of 1.2tonnes, which

Efficient earthmoving is allowing productive road construction in the Egyptian desert, Mike Woof reports. Despite ferocious desert temperatures, efficient earthmoving operations will help build new road links in Southern Egypt. Close to the Egyptian city of Assuit, the contractor Orascom is working on three key desert highway projects that will provide vital transport connections for the country's growing economy.
