An aerial ropeway hazard sensing system including a radar sensing unit mounted at a position along a ropeway that generates radar data representative of predetermined ropeway conditions proximate the radar sensing unit, and a processor that analyzes data from the radar sensing unit to detect predetermined hazard conditions and to generate a hazard detection signal indicative thereof. A method of performing an aerial ropeway safety function comprises using radar to detect a hazard condition and generating a hazard detection signal in response thereto; generating a control signal in response to the hazard detection signal; and initiating a safety with the control signal.

A skiing accessory comprises a support structure, a mounting arrangement and a lift member. The support structure is configured to support a user relative to a body of water. The mounting arrangement is configured to connect the support structure to a ski boom. The lift member is arranged on the support structure and configured to engage the body of water such that the support structure is raised or lifted, relative to the body of water, by the lift member as the accessory is towed. The mounting arrangement permits the support structure to be pivotally connected to the ski boom about an axis that is generally parallel to the ski boom.

The invention relates to a winch system intended, in particular, for water sports, comprising at least one frame, at least one motor, a brake system, and a main tension cable wound around two spools, each spool being actuated by a motor such that when one of the spools unwinds the main cable, the other spool winds up the cable such as to maintain both the unwinding speed and the tension required for the main cable.

A towing system comprises towers arranged relative to a skiing surface; a pulley on each tower; and a motor effecting rotation of at least one pulley. A cable passes along the pulleys and forms a closed loop between the towers. A towing element is coupled to the cable for towing a user along the skiing surface. The towing system features a rigid member extending along its axis from a tower to a support surface spaced from the tower so as to form an angle with the support surface thereby holding the tower upright. The rigid member is arranged to have tension therein along its axis at the angle with an adjustable length along the axis for tensioning the cable. Also, the rigid member is substantially rigid when its adjustable length is set so as to resist movement of the tower from its set working position. Furthermore, the towing system features a measuring device arranged to measure tensile force in a tensioned member of the towing system for determining tension in the cable.

In order to enhance the safety of a cableway, in particular when a cable car passes through a cableway support of the cableway, according to the present teaching a detection device having at least one evaluation unit and at least two sensors connected to the evaluation unit is provided on at least one cableway support. A first sensor is located in the entry area of the cableway support in order to detect the presence of a cable car in a detection area of the first sensor. A second sensor is located in the exit area of the cableway support in order to detect the presence of a cable car in a detection area of the second sensor. The detection device is provided in order to detect a number of cable cars between the first sensor and the second sensor and to generate a fault signal when the detected number exceeds a predefined maximum number.

This vehicle includes a guard rail intended to occupy a lowered position delimiting a closed space that prevents a passenger from falling and a raised position in which the guard rail opens up the space at the front of the vehicle to allow one or more passengers to board and disembark. The vehicle also includes means for locking the guard rail in the lowered position, wherein the locking means includes a locking lever having a first end provided with a bearing surface and with a blocking surface, the bearing surface and the blocking surface delimiting a first housing intended to accommodate part of the guard rail, and a second end in which a locking member designed to immobilize the second end of the locking lever is intended to engage when the guard rail is in the lowered position.
