Specifications:
The document outlines various extensions (JIB) for excavators, suitable for machines ranging from 1.5 to 15.0 tons. The extensions are available with pin connections and plates for classic and universal quick couplings. Key specifications include maximum weight capacities and lengths for different models (PR 300, PR 500, PR 700, PR 1100, PR 1300), with corresponding suggested log grabs.

Procedures and Recommendations:
It is crucial to adhere to the operating limits of the excavators to ensure safe and effective performance. The document emphasizes the importance of proper hydraulic pipeline management and the use of customized links for structural integrity.

Standards and Safety:
Each extension's maximum loading capacity is indicated on the CE identification plate, which is the binding data for safe operation. The document also mentions the provision of a standard log pusher tool to secure plants before felling.

Key Features:
The extensions are designed to maximize the productivity and versatility of excavators. Attention to hydraulic pipeline routing and structural strength are highlighted as significant features.

Additional Information:
The combination of boom extension and excavator shown in the table is exemplary and not binding; the critical factor is the maximum loading capacity indicated on the CE plate.
