A shovel, comprising:
- a lower travelling body;
- an upper pivot body pivotably mounted to the lower travelling body;
- a cabin provided to the upper pivot body;
- an actuator that drives the lower travelling body or the upper pivot body;
- an operation lever mounted in the cabin and operated to move the actuator;
- an object detection device provided to the upper pivot body;
- and
- a hardware processor that brakes the actuator, wherein the hardware processor automatically brakes the actuator in response to the object detection device detecting an object while an operator is performing an operation with the operation lever, and deactivates the braking in response to determining that the operator has an intention to continue the operation, and
- the hardware processor determines that the operator has the intention to continue the operation in response to determining that the operator has performed another operation with the operation lever after the braking of the actuator.
