4. Configuración e instalación
Proper installation is crucial for safe and efficient operation. Follow these steps to install the JET Manual Trolley:
- Selección de haz: Ensure the overhead beam is capable of supporting the trolley and the maximum intended load. Refer to the beam manufacturer's specifications.

- Reassembly on Beam: Position the trolley on the beam. Reattach the removed side plate and wheel assembly. Secure the castle nut and cotter pin. Ensure the cotter pin is fully spread to prevent the nut from loosening.
- Movimiento de prueba: Before attaching any load, push the trolley along the beam to ensure it rolls smoothly without binding or excessive play.
- Attach Hoist: Connect your lifting device (e.g., chain hoist) to the trolley's load bar. Ensure all connections are secure and rated for the load.

5. Operación
Operating the JET Manual Trolley is straightforward, but always prioritize safety.
- Comprobación previa a la operación: Before each use, perform a visual inspection of the trolley, beam, and lifting device. Check for any damage, obstructions, or loose parts.
- Accesorio de carga: Securely attach the load to the lifting device's hook. Ensure the load is balanced to prevent swinging.
- Levantamiento: Use the attached hoist to lift the load clear of the ground or any obstructions.
- Movimiento: To move the load horizontally, apply steady, even force to the load or the lifting device. Avoid sudden jerking motions. The trolley is designed for manual pushing/pulling.
- Posicionamiento: Guide the load to its desired location. Ensure the path is clear.
- Encapotado: Once positioned, carefully lower the load using the lifting device. Ensure the landing area is clear and stable.
