Movietech Phoenix-Kran-Parallelogramm-Verbindungsfehler während der Geräteprüfung
18 Jahre alt. Geräte und Preise können sich seitdem geändert haben.
Was die Diskussion ergab
- Eine Parallelogramm-Stabilisierungs-Verbindung eines Movietech Phoenix-Krans trennte sich, während die Plattform unter Last stand, wodurch die Plattform um 90 Grad gedreht wurde und der Insasse kopfüber schwingte
- The parallelogram post consists of sectional pieces approximately 4 feet long that connect together, and the connection mechanism uses an internal clamp that engages a knob but provides no visible confirmation of proper engagement
- The crane remained stable under the load of a person and additional weight for at least 5 minutes before the sudden connection failure occurred
- The lack of visual locking confirmation on the parallelogram bar sections creates a safety risk because operators cannot verify that sections are properly connected
- Crane step-offs involve undisclosed safety concerns and may not be covered under standard insurance or OSHA regulations
Hängt ab von
- The account describes a single incident from 2008 and does not cover whether the design issue was subsequently addressed by the manufacturer
- The mechanical analysis is acknowledged by the reporter as preliminary rather than comprehensive
- The connection mechanism's exact design specifications are not fully detailed in the discussion
