Logging-on’s first issue of September covers the full extent of forest engineering. Husqvarna brings new battery powered chainsaws to the market. The development of this technology is quite phenomenal as the power output increases and the charging time decreases. All logging machine owners battle with the question of when to sell their equipment. Researchers have assisted us by investigating some of the factors that influence machine value over time. Technology to improve safety (and by default – productivity) is rapidly being development and improved upon. Cat brings their new, and significantly enhanced, Connected Worker system to improve job site safety in hazardous occupations such as logging. On the roading front, we look at new developments from Maccaferri that improve their already legendary Reno Mattress for soil and slope stabilisation. Finally, we examine a new quick coupler option from Moipu.
