摘要： An electric winch device including an electric motor that rotates a winch drum in a hoisting direction, and generates regenerative electric power when a rotation of the winch drum in a lowering direction is transmitted to the electric motor, a transmission device that transmits the rotation between the electric motor and the winch drum, a power calculating section that calculates power of the target object by freefall, and a control section that controls an operation of the transmission device. When the power calculated by the power calculating section exceeds reference electric power, the control section causes the transmission device to change the transmission rate of the rotation to a transmission rate at which the regenerative electric power generated by the electric motor is equal to or smaller than the reference electric power.

摘要： 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.

摘要： An electric winch device includes a required braking force estimation section which estimates a required braking force required to stop a free-falling object at a position at an allowable stopping height; a braking force determination section which determines, out of an operational braking force, each of a first braking force to be borne by a braking device and a second braking force to be borne by a braking force which is generated in an electric motor due to consumption of regenerative power; and a control section which causes the braking device to apply the first braking force to a winch drum. The braking force determination section determines the first braking force to be a braking force equal to or greater than the required braking force when, at a time of stopping of the free-falling object, the operational braking force is equal to or greater than the required braking force.

摘要： Provided is an electric winch device including: an electric motor; a winch drum; a brake; an operation lever; and a controller. The controller includes: a first torque derivation unit which derives a value of a first torque applied to the winch drum due to a load of an object; a second torque derivation unit which derives a value of a second torque generated in the winch drum by a drive torque of the electric motor; and a brake control unit which determines a timing for releasing a braking action on the winch drum after the operation lever has been operated, on the basis of a differential between the second torque value and the first torque value, and which causes the brake to release the braking action on the winch drum by transmitting, to the brake, a control signal instructing release of the braking action on the winch drum at the determined timing.

摘要： An obstacle detection device detects an obstacle existing in one or more monitoring areas that are set to correspond to a movable part. A state determination unit determines whether a state of the actuator is a standby state or a suspended state under circumstances where the actuator is at a stop. On determination that the state of the actuator is the standby state, a display control unit executes automatic image output that is processing for causing a display device to display a monitoring image corresponding to a monitoring area in which the obstacle is detected out of the one or more monitoring areas. On determination that the state of the actuator is the suspended state, the display control unit stops the execution of the automatic image output.
