A heli-hoist platform for a wind turbine includes: a deck plate accessible by a worker from a helicopter; a barrier provided along the periphery of the deck plate; and a pair of support brackets extending along a longitudinal direction of the heli-hoist platform at both ends in a width direction of the deck plate.

A reinforcement object is reinforced without being carried out from a wind turbine power generation facility. A method of remodeling a wind turbine power generation facility includes: a carry-in step of carrying a reinforcement member into a hub through an opening portion which has a smaller dimension than a reinforcement object inside the wind turbine power generation facility and which brings into communication inside of the hub and outside of a front side of the wind turbine power generation facility, the reinforcement member having a smaller dimension than the opening portion; and a reinforcement step of processing the reinforcement object inside the hub, and reinforcing the reinforcement object by using the reinforcement member carried into the hub.

A planetary gear train is provided with: a carrier; a planetary gear; a planetary pin inserted into an insert hole provided through the planetary gear and coupled to the carrier to rotatably support the planetary gear; a thrust collar attached to a surface opposed to the planetary gear of the carrier so as to surround the planetary pin; and a pin for coupling the thrust collar to the carrier. The thrust collar has a first surface opposed to the carrier and a second surface opposed to the planetary gear, and has a first pin hole provided on the first surface so as not to reach the second surface. The carrier has a second pin hole on a surface opposed to the planetary gear. The thrust collar is attached to the carrier by inserting the pin into the first pin hole of the thrust collar and into the second pin hole of the carrier.

A starting method is provided for a rotating machine which includes a main shaft, a main bearing rotatably supporting the main shaft and a main bearing lubricant pump circulating lubricant through the main bearing. The starting method includes steps of: rotating the main shaft to raise a temperature of the main bearing in a state in which the main bearing lubricant pump is not operated; and operating the main bearing lubricant pump to start supplying the lubricant to the main bearing after the step of raising the temperature of the main bearing.

A planetary gear train is provided with: a planetary gear; a planetary pin for supporting the planetary gear; a carrier for supporting the planetary pin; and a housing for accommodating at least a portion of the carrier, the planetary gear and the planetary pin. The planetary gear is rotatable with respect to the planetary pin by a bearing. An oiling flow path for supplying lubricant oil to the bearing is formed inside the carrier. The carrier receives the lubricant oil into the oiling flow path from an oiling member stationarily fixed to the housing. The inlet for receiving the lubricant oil into the oiling flow path of the carrier from the oiling member is positioned inside the housing.
