Claims

[Scope of utility model registration request]

a base machine equipped with a main winding drum for winding a main winding rope and an auxiliary winding drum for winding an auxiliary winding rope;
A boom is attached to the base machine so that it can be raised and lowered freely, and has a boom point sheave at its tip through which both the main and auxiliary ropes are passed, and the main hoist rope is suspended by the auxiliary rope during grab work. The grab bucket is equipped with a grab bucket that is opened and closed by the crane, and a crane hook that is suspended by the main hoisting rope during crane work. A lower sheave block is formed by attaching a plurality of lower sheaves to a sheave frame, each of which is detachably attached to a bucket frame, and the crane hook includes:
The hook body is detachably attached to the sheave frame of the lower sheave block which is removed from the bucket frame of the grab bucket cart during crane work, and the hook body is detachably attached to the sheave frame of the grab bucket cart which is removed from the grab bucket cart frame during crane work. A crane/grab working machine characterized by having a support member attached to and detachably hung from the tip of the boom.
