Coolers and harnesses on machines like stone crushers and screeners, concrete pumps, air compressors and other off-road equipment are daily put to the test due to vibrations and external forces, as well as the fine stone dust in quarries and mines. With two new enhancements, Volvo Penta aims at further improving engine uptime – and, eventually, minimizing the total cost of ownership for engines working in these difficult environments.
The heavy-duty coolers will be available in 2013 as options on Volvo Penta D5, D7, D13 and D16 Stage IIIB/Tier 4i engines as well as D13 and D16 Stage II engines, which covers a range from 129 kW up to 565 kW. They will also be offered for the new Tier 4 Final range; D5, D8, D11, D13 and D16 in 2014.
“Our number one priority within this project was to develop a range of radiators suitable for stone crushers and screeners, but the same cooling package can also be used for concrete pumps, air compressors and other off-road construction equipment,” said Johanna Borgudd, Product Manager Industrial Engines for Volvo Penta.
The new side-by-side, heavy-duty cooling packages withstand cleaning with high-pressure water, and will be offered as suction- and pusher-type cooling systems available for all heavy-duty radiator units. The D5-D7 packages will be available as a kit including hoses, brackets for engine mounting, pipes, expansion tank, and mounting instructions. The D13–D16 packages will be available as a kit including hoses, pipes, expansion tank, and mounting instructions. The customer can also choose to have the cooling package transport-mounted from the factory.
Volvo Penta’s new, heavy-duty cable harnesses are based on a new manufacturing technique that uses a split synthetic polyester tubing as cable protection. The tubing, which has a smooth and soft inside, is simply wrapped around the cables. This means that the tubing is completely filled and that the cables inside the tubing are practically immobile, even at high vibrations. The cables are also protected from chafing due to stone dust penetrating the tubing.
The heavy-duty cable harnesses are now standard equipment on all Volvo Penta industrial engines.
