The invention provides a maintenance platform for an electric grab bucket for a ship unloader. The maintenance platform comprises a ship unloader structure; a driving mechanism assembly and a support are mounted on an upper portion of the ship unloader structure; first turnabout pulleys are mounted at intervals at the top of the support; a guard barrier is mounted on a side portion of the support; a guard steel wire rope fixing lug plate is mounted on the support located on a lower portion of the guard barrier; a hinged point supporting seat is mounted on the ship unloader structure; a platform capable of rotating around the hinged point supporting seat is mounted on the hinged point supporting seat through a rotating shaft; two first fixed lifting lugs and one second fixed lifting lug are arranged at intervals at the bottom of the platform; two second turnabout pulleys are arranged at an output end of the driving mechanism assembly, respectively; two driving steel wire ropes are released from a coiling block of the driving mechanism assembly, orderly wound around the second turnabout pulleys and the first turnabout pulleys, and finally fixed at the first fixed lifting lugs; a guard steel wire rope is mounted between the second fixed lifting lug and the guard steel wire rope fixing lug plate. Free raising and laying down of the maintenance platform can be realized reasonably; moreover, the maintenance platform is high in degree of automation, and safe and reliable.
