Claims

[Scope of utility model registration request]

In a crane equipped with a telescoping girder consisting of two girder members, the lower girder member being able to expand and contract with respect to the upper girder member, the movement of the trolley that is movable along the lower girder member can be suppressed. A telescopic girder type crane characterized in that a stopper device for fixing the trolley is provided on the lower girder member so that the lower girder member can move first when the girder is expanded or contracted.
