The FDNY responded to the scene at 1227 Broadway between 29th and 30th Street around 3:10 p.m. Thursday.
Officials said the 24-year-old construction worker was riding the elevator approaching the 33rd floor when he apparently dropped his phone and was fatally injured.
Police said he was crushed by a metal saddle that protruded from the elevator shaft. The worker was pronounced dead at the scene.
The death appears to be accidental, and an investigation is ongoing.
The identity of the victim has not been released.
