Title:
ELECTRIC WINCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/013430
Kind Code:
A1
Abstract:
This electric winch device is provided with: a required braking force derivation unit (44) that derives a required braking force which is the braking force required to stop a free-falling object at a position at an allowable stopping height set by a setting unit; a braking force determination unit (50) that determines, from among an operational braking force derived by an operational braking force derivation unit, a first braking force to be borne by a braking device and a second braking force to be borne by a braking force that is generated in an electric motor due to the consumption of regenerative power; and a control unit (52) that imparts the first braking force, which has been set by the braking force determination unit to the braking device, to a winch drum. The braking force determination unit (50), in the event that the operational braking force derived by the operational braking force derivation unit (44) when stopping the free-falling object is equal to or greater than the required braking force, sets the first braking force to be equal to or greater than the required braking force.
