Sandvik and Volvo Penta collaborate on Stage V underground LHDs

Sandvik says it is readying the release of its first Stage V compliant underground loaders for hard-rock mining applications following extensive testing.

In early 2020, the company’s newest intelligent loaders, the Sandvik LH517i and Sandvik LH621i, will get the Stage V treatment. The Stage V Volvo Penta engines will be globally available as options, but require ultra-low sulphur fuel and low-ash engine oil to operate, Sandvik said.

The planned release follows more than 10,000 hours of LHD testing underground, on multiple customer sites in Europe, and with millions of hours of on-highway experience from Volvo. This has led to the new technology meeting customer expectations, equipment performance requirements and the most stringent emission regulations valid at the moment, according to Sandvik.

The base engine and selective catalytic reduction (SCR) purifier are proven Volvo technology, enhanced now with a ceramic diesel particle filter (DPF), according to Sandvik.

“As a result of the collaborative product development work, the engine – delivered by Volvo Penta – and Sandvik load and haul equipment work seamlessly together to maintain productivity and reliability in the most challenging environments,” Sandvik said.

The benefits of Stage V compliant loaders include reduced amounts of particles in the diesel exhaust – helping mines to improve air quality underground – and the ability to operate with up to 3% reduced fuel consumption, compared with previous stage engines.

Sandvik said: “Another key enabler for the equipment availability is passive regeneration of the diesel particulate filter; the soot accumulated in the filter is burned off during equipment normal operation, without the need for frequent stand still regeneration.”

A new feature in the Stage V engine is the modulating engine brake, which enables the operator to adjust the engine braking power, allowing for better control of vehicle speed downhill, while minimising brake and transmission overheating and brake wear. Both the modulating engine brake and the passive regeneration contribute to high uptime of the equipment.

Added benefits of the Stage V engines include high altitude operating capability – up to plus-3,500 m above sea level – and lower noise levels compared with previous Stage engines.

RCT’s Kalgoorlie branch makes quick work of automating Sandvik LH621i LHD

RCT says it has successfully installed its autonomous technology on the recently released Sandvik LH621i underground loader for one of its clients in Western Australia’s Goldfields.

Earlier this month, RCT’s Kalgoorlie branch received the loader and commissioned the ControlMaster® Guidance automation technology package only weeks after the machine was first released to the Western Australia market.

The ‘i’ series represents Sandvik’s latest iteration of its underground loader range and, according to Sandvik, is the LHD of choice for rapid mine development and large-scale underground production. It is a matching pair with the previously introduced 63-t payload Sandvik TH663i truck.

ControlMaster Guidance Automation means machines can automatically tram between production level locations at higher speeds while also providing real time, graphical machine information to operators situated in remote automation centres, RCT said.

RCT Kalgoorlie Branch Manager, Rick Radcliffe, said the company could install and commission the Sandvik LH621i loader and deliver it to site within a relatively short lead time.

“Now that we have documented the new LH621i, all future ‘i’ series loaders can be commissioned in exactly the same amount of time as traditional Sandvik 621 loaders,” he said.

“This work follows on from a previous project where we commissioned two Sandvik LH517i loaders in the Kalgoorlie workshop for clients in the region.”

Bingham Equipment receives Hard-Line distribution rights in Arizona

Hard-Line says it has signed up Bingham Equipment Company as the company’s newest distributor in Arizona, USA.

With 11 locations in Arizona, Bingham Equipment will distribute Hard-Line’s LP401, MT52, and the RRC.

The LP401 (pictured) is a remote control operated low profile loader (skid steer) that can be used in a variety of restrictive areas where a normal man-operated machine cannot operate, Hard-Line said. The MT52 is a mini track loader that can “dig, trench, move materials and reach small, tight spots”, while the RRC is a versatile radio remote control that can operate any machine, make and model and is designed to be used in rugged and harsh environments, the company said.

Chad Rhude, Hard-Line’s Vice President, US Operations, said: “We are excited to be working with a great partner like Bingham Equipment Company. With their excellent reputation and many locations throughout the state of Arizona, it gives us a local presence for sales and support of our LP401 product line.

“We look forward to working with Bingham to showcase the versatility and capability of the LP401 in delivering a low-profile, fully-remote controlled machine platform to enhance safety and productivity in the municipal, construction and agriculture sectors in Arizona.”
