At the 2010 Bauma show Liebherr exhibited a block handling equipment package for the L 586 2plus2, intended specifically for the handling and transport of large stone blocks.
When blocks of stone intended for further processing are extracted, it is preferable for them to be as large as possible. The maximum weight that the L 586 2plus2 can carry is influenced by operating conditions, but depending on lifting height and the stone block’s centre of gravity, it is possible to handle blocks weighing at least 24 metric tonnes.
The Liebherr block handling package consists of various purpose-designed equipment options, including various stone fork patterns, shovels and a special tearout tooth. This extensive range of equipment enables the wheel loader to be closely matched to a variety of operating conditions and loading tasks. For maximum flexibility, the block handling package includes a quick-change device for the working attachments.
The new block handling equipment package means that companies operating in this specific area can now benefit from the quality and the many system-related advantages of Liebherr’s wheel loaders with hydrostatic transmission. These advantages include fuel consumption that is as much as 25% lower than wheel loaders with conventional transmission, an effectively wear-free service brake, minimum tyre wear and safe, convenient single-lever control.
Since steep gradients are encountered in stone quarries, the braking effect of the hydrostatic transmission with its automatic self-locking action makes a major contribution to safety, and also avoids overheating of the brake system and axles.
