Applications and Compatibility

Compatible Equipment: 306E2/307E2 mini excavators, 226B3/236B3 This product is used in skid steer loaders to prevent hydraulic cylinder piston rod detachment, ensure safe connection of linkage mechanisms, and prevent fall of attachment quick-change devices, thus preventing accidental component detachment and ensuring operational safety.

Application Scenarios: Suitable for vibration and impact conditions, such as boom lifting, stick extension, and bucket tilting in excavators, preventing component breakage and detachment that could cause safety accidents. Suitable for complex working conditions such as excavation and loading.

Compatible with: Uses with safety hooks, mounting brackets, and bolts. After installation, ensure reliable connection and effective anti-detachment. Suitable for heavy-load and vibration conditions.

Installation and Maintenance Points:

Installation: Clean the mounting surface. Connect the lifting lugs at both ends of the tethering rope to the lifting lugs and mounting brackets respectively, and tighten with bolts (torque 30-35 N·m) to ensure a reliable connection without loosening.

Maintenance: Inspect the tethering rope for wear, broken strands, and sheath damage every 100 hours. Replace immediately if problems are found. Avoid contact with sharp objects and high-temperature surfaces to prevent rope damage.

Replacement: When disassembling old parts, check for wear on lifting rings and connectors. Install new parts in their original positions to ensure a secure connection, effective anti-detachment, and suitability for equipment operating conditions.
