L 580 LogHandler

Use in the Livrabois sawmill in Arlanc, France

SituationLivrabois, based in Arlanc, has been operating in the timber industry since 1986 and has established itself as the leading producer of sawn timber pallets for the construction and packaging industries. In 2013, Livrabois and its now 60-strong workforce became part of the French Gallien bois Holding, which processes wood at two other production sites in France.

TaskHuge amounts of timber are trucked into the sawmill in Arlanc. The logs are cut, dried and processed into wooden pallets on several production lines. Livrabois produces around 80,000 m3 of lumber annually. Sawdust and wood chips are produced from the by-products of the sawn timber production. The main tasks of a timber handling machine at Livrabois include loading and unloading of trucks, loading of the debarking and sorting system as well as handling and transporting round timber with high stacking. For this purpose, the French company tested an L 580 LogHandler XPower® at the log yard in Arlanc. This LogHandler has been developed especially for the requirements of the timber industry.

SolutionThe Liebherr demonstration machine performed extremely well and impressed Mr. Gallien, Managing Director of Livrabois, and in February 2019 the company added an L 580 LogHandler XPower®, exhaust emission stage IV/Tier 4f, to its fleet. The deciding factor in the purchase of the Liebherr

wheel loader was the high degree of machine stability. The positioning of components within the machines in conjunction with the enhanced ballast on the LogHandler produces a perfectly balanced machine that works safely and stably in all operations. When combined with the high degree of manoeuvrability of the Liebherr wheel loader, efficient work is ensured even in confined spaces.

The special lift arm gives the machine a long reach and enable it to easily manipulate the load at height. For use in Arlanc, the L 580 LogHandler XPower® has been equipped with a 3.6 m² heart-shaped grapple. The grapple can be rotated 360° and swivelled forwards and backwards. In addition, the numerous protection devices, such as the guard for the windscreen, the hydraulically adjustable log pusher which prevents driving over tree trunks, and the rear ram guard with additional protection all ensure the best working conditions.

The L 580 LogHandler XPower® also offers the system advantages of the Liebherr-XPower driveline. The Liebherr-XPower power-split driveline has proven to be particularly robust and efficient as the L 580 LogHandler XPower® travels significant distances on the company premises. The machine operators are enthusiastic about the rapid acceleration of the XPower® driveline and the high travel speed. The machine moves around 1,200 cubic metres of wood per day, and the wheel loader requires on average only 16.2 litres of diesel per operating hour despite the rigorous operating conditions.

Even in confined spaces, the L 580 LogHandler XPower® can manoeuvre efficiently.

The special lift arm of the L 580 LogHandler XPower® means that the machine has a long reach and is able to easily manipulate the load at height.
