1. A shovel comprising:
a lower-part traveling body;
an upper-part swing body rotatably provided above the lower-part traveling body;
an object detecting device provided in the upper-part swing body;
a control device provided in the upper-part swing body;
an operating device coupled to the control device; and
driven bodies including the lower-part traveling body, the upper-part swing body, a boom, an arm, and an attachment, and configured to be operated by an actuator through the operating device,
wherein the object detecting device is configured to detect an object in a detection space set around the shovel, and
wherein the control device is configured to
determine whether the driven bodies are operating through the operating device,
vary, upon determining that at least one of the driven bodies is operating, a size of a movable range being a range accessible to the at least one of the driven bodies, based on a state of the detected object, and
prohibit, upon determining that at least one of the driven bodies is not operating, operation of the at least one of the driven bodies based on the state of the detected object.
