Provided is a braking apparatus for braking of an electric winch of a construction machine, ensuring safe braking with much regeneration. The apparatus includes a regenerative-power generation unit, a regenerative-power receiving unit, a braking device for mechanical braking separately from the regenerative-power generation unit, and a braking control unit including a necessary-braking-capacity calculation section, a regeneration-capacity calculation section calculating a regeneration capacity, and a command section. The command section, when the regeneration capacity is not less than a necessary braking capacity, performs braking with only a regenerative action while not operating the braking device and, when the regeneration capacity is less than the necessary braking capacity, calculates an auxiliary braking force equivalent to a difference between the necessary braking capacity and the regeneration capacity and brings the braking device into braking action with the auxiliary braking force.
