An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable (8) as seen in FIGS. 1A and 1B. The trolley comprises front and rear pulleys (44F) and (44R) conjoined via pulley housing (16) with left and right horizontal handles (10L) and (10R) attached to vertical shaft (12). Front and rear hand brake levers (20F) and (20R) are mounted onto left and right horizontal handles (10L) and (10R). When front and rear hand brake levers (20F) and (20R) are squeezed by the rider, they create a constricting force on front left and right calipers (32FL) and (32FR) along with rear left and right calipers (32RL) and (32RR) of FIGS. 2A and 3A. Thus, friction is applied to front and rear pulleys (44F) and (44R) via front left and right brake pads (34FL) and (34FR) along with rear left and right brake pads (34RL) and (34RR). This frictional force slows the rider's speed to his or her desired rate and brings the rider to a safe stop at a precise location along suspended cable (8).

A traveling mechanism for a lifting device, especially for a lifting device having a laterally cantilevering boom, is movable on rails with at least two running wheels. A connection element for attaching a load to said traveling mechanism is supported in the rail by the running wheels which are arranged on both sides of the connection element. The connection element has, at the region projecting down out of the rail, at least one running roller which is freely rotatable about a horizontal axis and rolls on a horizontal outer running surface of the rail. To effectively divert horizontal forces and uniformly distribute the vertical forces to the running wheels, running wheel axles are rigidly connected with a running wheel carrier, and the running wheel carrier and connection element are swivelably connected by a universal type joint. In addition, at least one support roller is rotatably mounted at the connection element in the interior of the rail. The support roller freely rotates about a vertical axis and rolls along at least one of the side surfaces to transmit horizontal forces to the rail.

A traveling highline aerial cable rail system for moving objects over large distances in three-dimensional space. A pair of track dollies mounted beneath substantially parallel and distantly separated support trusses allow the entire load bearing highline itself to traverse X-axis space. The highline defines the Y-axis of the system and supports a skate that moves along this axis. A platform suspended from the skate moves vertically in the Z-axis and can support extremely heavy loads depending on the gauge of the rope used in the system. A three motor pulley system with a multiplicity of sheaves allow independent movement of all three axes. The system can move objects weighing thousands of pounds stably at 60 miles per hour or more through three-dimensional space. The system can be modularly widened along the X-axis by adding truss sections, and the highline can be configured to up to 1000 feet or more, using rope that can support several tons or more. The Z-axis displacement can be multiplied via a pulley arrangement.

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.

The boarding area (A, B, C) of a transport means (9) is divided into at least two gates (1, 2, 3), the maximum person capacity of which corresponds, respectively, to the maximum capacity of the largest transport means (9) that is accessible via the boarding area (A, B, C). Entrance into the gates (1, 2, 3) is effected via at least one separating device (4) connected with the control system (5) for the purpose of data communication. Entrance into a gate (1, 2, 3) is not possible once the number of persons in the gate (1, 2, 3) specified by the control system (5) for the current boarding operation is reached, or while the persons inside a gate (1, 2, 3) board a transport means. The number of persons in a gate (1, 2, 3) specified for the current boarding operation is determined by the control system (5) in dependence upon the transport demand in subsequent intermediate stations ahead of an end station, provided intermediate stations are present, and of the free capacity of the arriving transport means (9). For the current boarding operation, the persons inside a gate (1, 2, 3) are assigned to an arriving transport means (9). When the number of persons inside the gate (1, 2, 3) specified for the current boarding operation has been reached, or when a specified timer which corresponds to a specified time window has expired and a transport means (9) arrives to which the persons currently in the gate (1, 2, 3) are assigned, the persons who are inside the gate (1, 2, 3) are requested to board and a counter for the number of persons in the gate (1, 2, 3) is set to zero.
