A trolley includes a housing, at least one sheave rotatably mounted at least partially within the housing, and a braking mechanism. The braking mechanism includes a rotor assembly coupled to the at least one sheave, at least one conductive element, and at least one magnetic element. The rotor assembly is rotatable with the at least one sheave, and when the rotor assembly rotates, the at least one conductive element overlaps with the at least one magnetic element based at least in part on a rotational speed of the rotor assembly.
