Claims

[Scope of utility model registration request]

A pair of hoisting sheaves that engage with a hoisting rope that lifts a grab bucket on the same axis and a pair of hoisting sheaves that engage with an opening/closing rope that opens and closes the grab are attached to the trolley body that travels on a travel path formed on the crane body. A crane trolley device having an opening/closing sheave includes a lever member that connects the trolley main body and the opening/closing sheave and rotatably supports the opening/closing sheave, and the opening/closing sheave is attached to the trolley. A trolley device for a crane, comprising a sheave shift means for moving the hoisting rope and the opening/closing rope apart from each other in the running direction of the trolley body by reciprocating the hoisting rope and the opening/closing rope in the running direction.
