An array of major manufacturers are introducing revamped and improved excavators to meet the latest requirements - Mike Woof writes. With efficiency, emissions and ease of maintenance all high up the agenda for customers, manufacturers have delivered a new generation of machines that offer increased output while using less fuel. The firms have all developed new models that meet the latest stringent emissions requirements. Ranging from 25-40tonnes, Case Construction Equipment has four new D Series craw

Caterpillar has raised the bar for articulated dump truck performance with the introduction of its C Series to replace its B series ADTs. All the new Cat 735C, 740C EJ and 745C ADTs have engines that meet US EPA Tier 4 Final/EU Stage IV emissions standards. The machines also incorporate many new and upgraded features designed to boost the operator’s efficiency, ensure a longer life cycle of the vehicle and save fuel. Rated payload capacities for the new models are 32.7tonnes for the 735C, 38tonnes for the 7

Terex Trucks is appointing Rumaillah Motors WLL as its new dealer for Qatar. This pivotal move is intended to boost dealer support for the haulers from Terex Trucks, which are built in Motherwell, Scotland.

The partnership with Rumaillah Motors follows Terex Truck’s recent acquisition by Volvo Construction Equipment.

A life-cycle assessment has found that an asphalt mix containing a high percentage of reclaimed asphalt pavement (RAP) along with an additive by Arizona Chemical can produce a significantly lower carbon footprint than virgin asphalt mix or a mix containing a low percentage of RAP. The assessment study was carried out by third party Arthur D. Little, an international management consulting firm, using Arizona Chemical’s SYLVAROAD RP 1000 performance additive. The work noted that cradle-to-gate, a road aspha

Earthmoving equipment manufacturer Dressta is launching the first of three new hydraulic crawler dozers later this year, and has ambitious growth plans funded by parent company LiuGong, the Chinese construction equipment manufacturing giant. Guy Woodford reports Dressta’s trio of new hydraulic crawler dozers represent exciting additions to the dozer market and are the first results of parent company LiuGong’s significant R&D investment in the Polish firm, which it bought in 2012. Being launched in Q

A Caterpillar top hammer rig is said to be working well in a tough granite quarry operation in the US. The MD5150C rig is out-performing down-the-hole (DTH) rigs, with higher productivity and lower fuel consumption. Of note though is the fact that the machine is also delivering comparable hole straightness to the DTH machines. Iron Mountain Quarry is located to the south of St Louis, Missouri and the operation says that overall productivity from its Cat rig is almost double that of the earlier gener

Doosan has launched the 30tonne DX300LC-5 Stage IV compliant crawler excavator, providing greatly improved performance over the LC-3 Stage IIIB model. Bucket, arm and swing forces in the DX300LC-5 remain the same as the Stage IIIB model, but the drawbar pull has been sharply increased by 8%. The operating weight of the DX300LC-5 has increased 900kg, resulting in a lifting capacity increase of 1% over the front and 5% over the side. The new machine’s styling allows increased driver comfort and vehicu

Peri’s Variokit heavy-duty truss girder system has been designed specifically for tunnel and bridge construction to reach those hard-to-get places. The heavy-duty truss girder complements the Variokit heavy-duty shoring tower. Peri took into account the load-bearing capacity of the tower as well as the challenging requirements of everyday construction work.
