Abstract:
1. A releasing method for releasing a towed device from a cableway of a lift at desired release point as the towed device is towed upwardly on a sloping surface in a towing direction along a tow path without stopping the lift or without having a person to participate in the release, said method comprising: causing a towing member of the lift to release from a clutch member of the towed device at the desired release point by increasing a vertical towing angle between the towing member and the clutch member sufficient for the the towing member to be released from the clutch member at the release point; wherein the vertical towing angle between the towing member and the clutch member is increased by towing the towed device below a horizontal portion of a releasing member positioned on the tow path at the desired release point to thereby cause the towing member, while attached to the clutch member of the towed device, to be brought into contact with the horizontal portion of the releasing member and thereby responsively cause the vertical towing angle to be continually increased as the towed member is towed along the path until the vertical towing angle is sufficiently increased to allow towing member to be released from the clutch member, whereby the towed device is released from the cableway.
