Volvo shovels go logging for James Jones & Sons Ltd
Two new loading shovels have been supplied to James Jones & Sons Ltd for the company’s log handling activities at its Mosstodloch and Lockerbie sites, located in the north-east and south-west border areas of Scotland.
The two machines in question are a Volvo L110H, that has gone to work at the Mosstodloch mill in Moray, and the larger L120H, that has been deployed at their Lockerbie yard, both replacing competitive makes of machine. “We have operated Volvos at our Mosstodloch site for some time and we are quite aware of their abilities, but it’s been some fifteen years since we ran them here at Lockerbie,” explains Log Yard Manager, Iain Gale. “An opportunity arose to introduce an alternative make of machine into our Lockerbie operation, and here we opted for the larger L120H. There were several reasons for choosing the Volvos, these being a competitive package and sound third-party references, but the absolute key was the fact that Volvo offers external axle cooling as an option, and this really clinched the decision,” he continues. “The machines work at speed across the concrete pad, handling in excess of some 2000 tonnes of logs per day. So having this option is essential in avoiding axle and brake failures, which we experienced with the previous models.”
Furthermore, the patented TP loader linkage system on Volvo wheeled loaders lends itself perfectly for log handling applications since the machines demonstrate a high degree of breakout torque when crowding. This is due to the crowd ram pushing on the positive side of the cylinder as opposed to pulling on it, as can be found on Z bar linkage systems. The breakout torque, for example on the L150H is a massive 347KNm. In addition to the benefit of a high breakout torque, the Volvo TP linkage system is still able to demonstrate parallel lift, whether the attachment is a bucket, pallet forks or log grapples. Iain also explains why the two different sizes of the machine were chosen for the two sites: “It’s all about the weight and length of the logs in the log grabs and the daily production activity. In essence, we handle five-tonne of logs in the grabs at Mosstodloch whilst, here at Lockerbie, we handle a greater volume of longer logs, weighing between five to five and a half tonnes in weight, and the L120H gives greater stability when the logs are
