The OMEF PTH oscillating grapple saw is a powerful and versatile attachment designed for cutting and handling logs of various diameters on an excavator. Built for demanding forestry work and heavy-duty material handling, the PTH is available in two models capable of cutting from 450 to 900 millimetres in diameter.
The unit combines three key components:
• an oscillating rotator that enables full 360-degree rotation for maximum manoeuvrability
• a closed-tip, heavy-duty grapple with a maximum opening of up to 2 metres
• a hydraulic chainsaw kit capable of cutting logs up to 900 millimetres in diameter
This integrated design allows operators to grip, cut, rotate, and place logs with precision and efficiency, reducing handling time and improving safety on the job.
Technical Features
The grapple structure is made from high-strength, wear-resistant steel, reinforced with heavy profiles and powered by a double cylinder for superior gripping force and stability.
The hydraulic system uses:
• a single-acting line for the chainsaw unit
• a double-acting line for the grapple
• a double-acting line for the oscillating rotator
Safety is ensured through an integrated block and relief valve, protecting the system under heavy loads and preventing accidental release.
To simplify installation, every PTH model is available with a complete turnkey kit, including a machine-specific mounting bracket and a dedicated hose kit.
