Solaris continues expansion of Warintza • New KamAZ mining dump truck launched

GHH launches new load haul dump truck

Heavy duty mining equipment manufacturer GHH has launched a new load haul dumper, the LF-7.

It comes with the biggest bucket and the best power rating, for highest operating slope angles, in the seven tonnes payload class, with a super low emission, super compact package.

The articulated LF-7 carries 7,000kg of payload in its bucket, but the vehicle is only 8.9m long in driving position, 2.24m wide at the bucket and 2,2m high at the cab when loaded, meeting the demands of large narrow vein and small mass mining operations.

At approximately 18 tonnes operation weight, the LF-7 is powered by a 164 kW Cummins diesel engine, complying with Tier 3 and 4 as well as EU Stage 5 emissions standards. The Dana transmission shifts forward and reverse in four gears each to cope with gradients of up to 28 per cent and to reach speeds of up to 27 km/h. GHH offers several LHDs with payloads from 3 to 21 tonnes.

news New KamAZ mining dump truck equipped with Allison fully automatic transmission

Russian OEM KamAZ has launched a new range of dump trucks for the mining sector. The KaMAZ-65805 Atlant dump truck features an Allison 4700 fully automatic transmission to support its market proposition as an efficient, economical and comfortable dump truck.

Developed by the KamAZ Science and

Technology Center, the KaMAZ-65805 is designed for the transportation of rock and ore material in medium and small quarries. It is capable of being converted into an autonomous vehicle. The Atlant truck range will include vehicles with a load capacity of 45 to 70 tons and with a 10x6 chassis. “We design new haul trucks with the market needs in mind by thoroughly studying the requirements of end users for this vehicle class,” said Sergey Nazarenko, chief designer of innovative vehicles at the KamAZ Science and Technology Center. “As one of the key vehicle components, the transmission is subject to increased requirements in terms of reliability, durability and manufacturability. These were the major factors for selecting a transmission for the new KamAZ Atlant. We opted for Allison Transmission.” The Allison 4700 transmission’s integrated hydraulic retarder was

specified to provide greater brake system service life and to address the challenge – particularly in quarries and mountainous areas – of slowing the truck effectively without overloading the brake system. Another valuable safety feature of the automatic transmission is that it virtually eliminates rollback when driving uphill. Founded in 1915, Allison is headquartered in Indianapolis, Indiana, USA, with regional headquarters in the Netherlands, China and Brazil and manufacturing facilities in the US, Hungary and India.
