The Dehard cutting, processing head is the state-of-the art processing head that allows for the quick measurement and bucking of logs while retaiing the safety of being in the excavator cab. Designed for quick automatic measurement, the Dehard system comes complete with Sure grips and display control for easy installation into 25 to 40 Ton excavators. 
 
Optimise your logyard management operations with our innovative grapple saw, specially designed for optimum economic efficiency since it doesn't require the construction of heavy structures.
Robust and versatile : equip your hydraulic excavator (20 to 35T) with the grapple saw for tight grip and easy handling of logs. Facilitate operations such as unloading trucks, picking up logs from the middle of the pile, accurately sorting logs by length and diameter, and quickly loading decks
Intelligent clamping pressure : the clamping pressure automatically adjusts according to the diameter of the wood, guaranteeing gentle handling while preserving the integrity of the material.
Precise, efficient cutting : incorporating a high-velocity Harvester saw, our grapple saw ensures precise, optimised cuts for logs up to 80 cm in diameter. Mechanical pump lubrication and an automatic tensioning system ensure consistent performance. The presence of a second saw means that off-cuts can be cut fully automatically.
Danfoss PLC : enjoy total control with the Danfoss PLC. Combining ease of use and robustness, it monitors and regulates lengths, diameters and volume with exceptional precision.
Precise measurements : length is determined by a pressure roller that can be adjusted to suit each tree. Diameter is determined by measuring five contact points, guaranteeing precise calculation.
