ABSTRACT:
An extendible bunk stake mounted on a logging vehicle has an extension member that can be raised and lowered within a support member by an operator. A remotely actuatable motor, such as a source of working fluid and an expansible working chamber can be enabled by an operator to raise and lower the extension member from a safe distance away from a log loading area of the vehicle. Particularly, during periods of inclement weather, a vehicle operator can safely raise and lower the extension member without having to climb on top of the vehicle, greatly reducing any risk of related injury.
