This seat includes a guard-rail able to occupy a lowered first extreme position and a raised second extreme position, and means for locking the guard rail when it is in a lowered position. The locking means include a bistable electromagnet provided with a rod that is able to move between a stable first position in which the rod allows the guard rail to lock in the lowered position by interposing an obstacle in the upward path described by a guard rail element to pass from the lowered position to the raised position, and a stable second position in which the rod allows the guard rail to unlock so that it can be moved into the raised position by moving the obstacle away from the upward path described by the guard rail element.

A display system is easily attached to the safety bar of a chair on a chair lift system at the beginning of a season. The display system includes brackets formed of rails holding clamp portions that may be fastened together to clamp the display system to a chair, such as to the safety bar across the lap of a rider. At the end of a season, the display system may be removed from each chair, the clamp portions removed, and the display systems stacked. In one simplified system, adjacent displays may be stacked back to back, and such adjacent pairs may be stacked with the displays in adjacent pairs positioned face-to-face. Thus, metal brackets on the backs need not scratch up the reading faces or surfaces. Meanwhile, the displays may be stored in minimal space, with great stability, while minimizing wear and damage.

Emergency egress systems carry multiple riders simultaneously accessing zip line catenary from higher, inaccessible, working locations to lower, safer areas. Hangers above the track line suspend trolleys to avoid weighting the catenary unduly at the high end, which might otherwise alter (reduce) clearance distances and safety of riders above a launch platform (deck). Catenary shape is controlled against approaching a launch deck by sequencing the release from the hangers of each trolley to roll along the catenary with its own rider. Autonomous braking, inter-trolley bumpers, and vertical stabilizers enable each rider to quickly occupy a seat (harness, etc.) and launch onto the track line, unconcerned with riders ahead or behind until underway. Multiple trolleys may thus load, launch, and in close proximity on a single line, regardless of the total weight of multiple riders.

A canopy tour system follow a route including multiple legs of track line, and may run multiple track lines in parallel along each leg, establishing the route of descent. Each leg extends between an associated upper station and lower station, used for loading, launching, receiving, and unclipping, respectively, riders of trolleys on the zip lines. A system of mechanical and electronic interlocks provides safety for users in remote locations, enabling individual riders to operate trolleys, including attaching and dis-attaching the trolleys from various track lines, unattended by other workers or employees of the canopy tour operation. Multiple trolleys may travel simultaneously and in close proximity to one another as a group on a single line. Each group traveling together is controlled by a single braking trolley ahead, behind, or in the midst of the group.

The invention refers to a chairlift loading apparatus comprising at least two adjacent timing gates for regulating a flow of persons passing through said timing gates, the loading apparatus comprising a high-risk situation detection system comprising: a detection device capable of determining the presence of a potential person passing through each of the timing gates and determining whether the potential person is taller than a predetermined height; and a data processing unit configured to determine, from the data from the detection device, the existence of a high-risk situation when a person who is shorter than the predetermined height is detected in front of a given gate of the adjacent gates, and no person who is taller than the predetermined height is detected in front of one of the adjacent gates.

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.

In a continuously moving cableway installation (9), a haul rope (13b) extends as a closed loop defining a transportation path (12). Suspended vehicles (14) can be connected to the rope by means of automatic coupling devices (24). Along the rope path, passenger stations (10) are provided, each providing ramps (22) to cause the clamping or release of the automatic coupling devices (24), fixed power supply conductors (30), and overhead rails (28). Mounted on board each vehicle (14) are: a motor-driven trolley (20), an electrical contact (30a) to contact one of the power supply conductors (30) in the passenger stations (10), an electric power battery (43), and an electric motor (42) with driving wheels (40) associated thereto, which are suitable for rolling on the overhead rails (28) in order to move the vehicle within and proximate to the passenger stations.

A cable car system has vehicles which are coupled to a conveying cable between stations. The vehicles are decoupled from the conveying cable in the stations and are moved through the stations along guide rails. The vehicles are formed with current collectors and the stations have associated power rails. In at least one of the vehicles there is located a circuit with at least one electrical load which is supplied with electrical energy via the current collector and the power rails. At least one second circuit with at least one further electrical load is located in at least one vehicle. The second circuit is supplied with electrical energy via a single further current collector and a power rail assigned thereto. The two circuits are connected to a common current collector to which a single power rail is assigned.

A belt-conveying aerial system comprising: a pair of top fixed load-bearing ropes, which are parallel to one another and are set at a distance apart from one another in a transverse direction; a pair of bottom fixed load-bearing ropes; and a belt conveyor comprising a plurality of modules, which are aligned along the load-bearing ropes, are fixedly connected to the load-bearing ropes, and guide a belt for conveying materials; the modules being connected to the load-bearing ropes via an installation vehicle having a supporting top carriage mobile on the top load-bearing ropes, a pair of resting platforms suspended from the top carriage, and, for each bottom load-bearing rope, at least one pair of wheels, which are rotatable in contact with the respective bottom load-bearing rope and are set upstream and downstream of the corresponding module.
