An automatic crossbar on a ski chair-lift for containing seated passengers and facilitating dismounting passengers. A vertically elongated bar (20) with a cross (20a) attached at its base is pivotably suspended from a passenger chair, positioning the crossbar in front of passengers. An elastic closure attachment (9), and/or an automatic locking mechanism (60), is attached between the elongated bar and the chair to retain the crossbar in a closed position and contain passengers. A blocking structure (200) is suspended proximal to the aerial cable above the landing platform. The elongated bar has an upper portion (20v) above its pivotal mount (21b) which impacts the blocking structure as the aerial cable moves the chair forward. The impact causes the upper portion to rotate back as the lower portion and crossbar are levered forward and upward. As the crossbar swings forward from the chair, passengers grasp the crossbar to balance with while standing onto the landing platform.

An apparatus monitors the locking of the safety bar of the chairs of an aerial cableway system. A first sensor determines the occupancy of the chairs and a second sensor determines the locking of the safety bar. The sensor output signals from these two sensors are led to a control device, which is enabled to switch the chairlift system off.
A stand includes a track mounted to a columnar member such as a tree trunk. The track substantially or completely encircles the columnar member. A seat is mounted to the track for movement thereon. A platform is mounted to the columnar member beneath the seat. The seat and platform are designed to move in concert with one another about the columnar member by a user sitting on the seat with his feet resting on the platform.
