The biggest ever Doosan articulated dump truck order in Scandinavia has been completed by Hæhre & Isachsen Maskinutleie, one of Norway’s largest machine rental companies. The company bought the 20 new Doosan DA40 articulated dump trucks (ADTs), which are Stage IV/Tier 4 Final compliant, from Rosendal Maskin, the Doosan dealer for Norway, based in Askim.

The new DA40s replace existing DA40 models in the Hæhre fleet and several more ADTs, and form part of a package, which includes a comprehensive service agreement between Rosendal and the Hæhre Group, encompassing 24/7 service with very quick response times. 

Hæhre & Isachsen Maskinutleie (part of BetonmastHæhre Anlegg, formerly called Hæhre), is also one of Norway’s largest road and civil engineering contractors, and is an established user of Doosan/Moxy ADTs. It has grown rapidly in recent years, and now has a fleet of over 100 dump trucks, including ADTs, RDTs, small dumpers and tracked dumpers.

The company will continue to use the new DoosanConnnect state-of-the-art, wireless fleet and asset management system to monitor productivity, utilisation rate and fuel consumption. 

Designed to meet increasing demand for fleet monitoring, machine-to-machine communication, machine intelligence and remote equipment monitoring, the DoosanConnect system offers a web-based fleet management solution, said to be very useful for monitoring the performance and security of machines and promoting preventative maintenance.

It is available as a standard feature on all new generation Doosan Stage IV compliant excavators (from 14tonnes), all new generation Doosan Stage IV compliant wheeled loaders and the new generation Doosan Stage IV compliant ADTs.

The new service allows owners and dealers to remotely monitor and communicate with Doosan machines via the DoosanConnect telematics website.

“This is the largest order for dump trucks we have ever placed. The DA40 is a very good product and we see advantages in offering one make of machine in this segment,” says Frank Ole Sørensen, CEO of Hæhre & Isachsen Maskinutleie.

“It also has to do with the training of the drivers and the service and maintenance work that is required. There are big differences in operating the different brands of ADT.”

With the 20 new DA40 ADTs being put into operation, 51 of the 59 ADTs in the Hæhre system will be from Doosan. Two of the remaining eight are dump trucks in sizes Doosan does not have in its range.

The agreement is also by far the largest ADT order for Rosendal Maskin. The previous record was also with Hæhre for ten Doosan ADTs.

“This means a lot to Rosendal and all machines are being delivered with a service agreement of five years or 10,000 hours.  We delivered 20 ADTs in total in 2017, so this is a great start to 2018,” says Ole Marius Rosendal, general manager of Rosendal Maskin. 

The DA40 features the Scania DC13 368kW selective catalytic reduction (SCR) and exhaust gas recirculation (ECR) diesel engine and the ZF EP transmission.

A Scottish family-run civil engineering and contracting business now has two Volvo A30G articulated haulers as part of its fleet of equipment.

A&L McCrae of Whitehouse, Argyll, headed up by Alistair and Linda McCrae, proprietors and founders, supported by their son Calum, broke with tradition when it bought its first Volvo branded machines.

They have been added to McCrae’s fleet of mixed equipment which includes excavators, wheeled loaders and mobile crushers, and they will be deployed on a range of contracting activities undertaken by the company.

“Taking the decision to change to a new brand of hauler has been a leap of faith, to be honest,” says Alistair McCrae.

“We took a close look at the market and having taken third-party recommendations into consideration, the projected residual values and lifetime operating costs, we felt opting for the Volvo haulers was the right decision.”

The A30G hauler meets the requirements of Stage-IV Final emissions legislation being powered by an electronically controlled, six-cylinder 264kW turbo-charged Volvo V-ACT diesel engine. This features high torque at low engine speeds, and this is said to result in good fuel efficiency, high performance, quicker engine response and less wear, meaning a long service life.

Purpose-built by Volvo, the engine is designed to exactly match the Volvo drive train, ensuring the best use of power and torque, even in tough working conditions.

With a carrying capacity of 28tonnes and heaped capacity of 17.5m³ the Volvo A30G has a maximum speed of 53km/hour.

The hauler is also fitted with CareTrack as standard, which is Volvo’s telematics system that enables remote monitoring of a wide range of machine functions such as location, fuel consumption and service reminders, thus optimising customer operations.

The two haulers supplied to A&L McCrae by SMT GB, which markets Volvo Construction Equipment products in Great Britain, have been equipped with optional cantilever tailgates.

The company’s typical contracts include general earthworks, road construction and surfacing, civil engineering, forest road maintenance and construction, and it also carries out contract crushing and quarrying from its own Barrachander Quarry near Taynuilt.

At Brassington Moor Quarry, near Matlock, county Derbyshire, central England, Longcliffe, the UK’s leading supplier of calcium carbonate and limestone, is using Terex Trucks’ haulers to move premium limestone and recycled materials.

The family-owned business supplies a variety of industries from animal feed manufacturers to glass, plastic, adhesive and construction businesses, and production is at an all-time high.

Longcliffe’s quarry is home to one of the purest and largest limestone basins in Great Britain, and in an around-the-clock operation the company extracts, processes and delivers more than one million tonnes of limestone and dolomite products/year.

TDL supplied a 55tonne payload TR60 to the quarry for demonstration purposes, but Longcliffe required a machine with a bigger payload, and it acquired the TR70.

With this machine transporting blasted rock from quarry face to processing plant, Longcliffe decided to add a TA400 articulated dump truck to its fleet to move limestone and recycled materials around the quarry.

Longcliffe’s partnership with Terex Trucks was established in 2013 when it issued a tender to replace a dump truck in its fleet.

“Terex Trucks and its dealer, TDL Equipment, came up with an offer that was as good as the one our existing equipment supplier was offering. This gave us the opportunity to try something different,” says Chris Wainwright, operations director at Longcliffe.

“The feedback on Terex Trucks’ rigid hauler was good, and following tests on fuel consumption, cycle times and carrying capacity, we wanted to give the machine a try.”

The Brassington Moor Quarry is split into two working areas that are connected by a tunnel, which was initially of concern for Gaz Bourne, TDL’s area sales manager, who was meticulous in ensuring that the TR70 was the right truck for the site, triple-checking the dimensions of the tunnel against the rigid hauler.

Longcliffe asked the Scottish manufacturer to modify the truck slightly to increase its body volume by adding side extensions.

The TR70 is fitted with a Detroit Diesel MTU-2000TA 12-cylinder, 24litre engine that provides a maximum torque of 3,323 Nm and a gross power of 567kW, and the high capacity body of the machine comes complete with a 15º sloping tail chute and exhaust heating for low material retention and cleaner dumping.

The TA400 achieves a payload of 38tonnes and is powered by a six-cylinder, Scania DC13 EU Stage 3B compliant engine that achieves a gross power of 331kW and a maximum torque of 2,255Nm.

Bell Equipment is growing the four-wheel drive concept with the new Bell B30E 4x4, which is suited to small- to medium-sized quarries with integrated aggregate production facilities.

According to Tristan du Pisanie, Bell Equipment product marketing manager, the new machine is a supplement to the company’s traditional 6x6 ADT range by providing a practical alternative to those customers who have had to choose between tipper trucks, rigid dump trucks and 6x6 articulated dump trucks.

In addition to smaller quarry operations, the 21.5tonne Bell B30E 4x4 will also target specific markets such as tunnelling, with the new two-axle ADT being based on the 6x6 model Bell B30E. sharing the front chassis and oscillation/articulation joint.
