I hope no one was hurt or killed when the tiltrotator and bucket fell off. Do you have the background info in english?
Tilt had fallen out of several construction sites. But cause the company had a lot of work, no one listened to the operators. No one died, but it was close. After the accident, Hitachi service technicians came to examine the machine, and they said that the hydraulic system was missing a valve. Hitachi service technicians announced what the machine needs to be done, but but the machine had to get back to work quickly, so the owner ordered the driver to weld a questionable chain to protect if bucket would drop.
