A trolley for supporting transporting units of a transportation system, wherein the transporting units are supported suspended from a guide defining a direction of movement; the trolley comprising: a frame; rolls supported by the frame and configured for resting and rolling on the guide; a suspending arm for supporting the transporting units, wherein the suspending arm pivots constrained to the frame about the direction of movement between a first and a second angular position; a rotation limiting device selectively operable for limiting or blocking the rotation of the suspending arm with respect to the frame.

An cable trolley comprising a transport structure having a top end and a bottom end, a cable engagement device disposed on the top end, and a swivel assembly disposed on the bottom end, the swivel assembly comprises a central axis of rotation, a support ring having an opening and a central axis of rotation, a sleeve, a retainer disposed on a first end of the sleeve and an adaptor disposed on a second end of the sleeve. The second end of the sleeve is configured to be inserted through the opening until the retainer of the sleeve comes in contact with the support ring and the sleeve is co-axially rotatable relative to the support ring. There is further provided either a carrier for carrying a user or a coupling link attached to the swivel assembly where the coupling link is configured to secure a user with harnessing equipment.

A cable car system has at least two cable car stations and at least one carrying cable between the stations. A cable car vehicle is moved by a hauling cable between the car stations. The travelling positions of the vehicle along the travelling route are determined by a measuring device and transmitted to a control unit and processed and stored in same. A signal is input into the control unit by an input device located on a cable car support such that maintenance or assembly works and similar are carried out on this cable car support. When a cable car vehicle approaches the cable car support, the drive for moving the at least one cable car vehicle is controlled by the control unit such that the cable car vehicle is moved at a significantly reduced speed in relation to the operating speed, or is stopped at the cable car support.

A skyline log conveying system having a skyline for extending between two elevated supports, one at or above a landing at which logs are deposited and another at a lower position at least as low as an area from which logs are to be moved. A carriage is rollably mounted to the skyline. A grapple is suspended from the carriage, the grapple having closed and opened positions for grasping and releasing logs. A hydraulic pump is mounted to the carriage. A rotatable member is driven by the skyline with the rolling of the carriage on the skyline for driving the hydraulic pump to generate hydraulic pressure. At least one accumulator is in hydraulic communication with the hydraulic pump, the at least one accumulator capable of storing pressure when hydraulic pressure is transmitted to it by the hydraulic pump. A hydraulic ram is hydraulically interconnected with the at least one accumulator and mounted to the grapple to selectively close the grapple to facilitate the grasping of logs.

Ropeway self-propelled transporting equipment, comprising a transporting device (1) which runs along a ropeway rope, wherein the transporting device (1) comprises a sliding adjusting mechanism (2), a transmission mechanism (3) and a pull arm (4); and the sliding adjusting mechanism (2) and the transmission mechanism (3) are movably connected to the pull arm (4) respectively. The sliding adjusting mechanism (2) is arranged on the pull arm (4), and a first transmission component (21), a second transmission component (22) and a third transmission component (23) of the sliding adjusting mechanism (2) enclose a ropeway rope clamping area. When the ropeway rope is positioned in the ropeway rope clamping area, the ropeway rope is clamped to the first transmission component (21), the second transmission component (22) and the third transmission component (23) so that the transporting device (1) may freely slide along the ropeway rope. In addition, a first lifting component (20) is provided on the sliding adjusting mechanism (2). The ropeway rope clamping area may adapt to ropeway ropes of different sizes and smoothly traverse a ropeway rope junction or a ropeway support bend. Therefore, the applicability of the present transporting device (1) is improved.

A cable transportation system comprising: at least a cable; an upstream station and a downstream station between which the cable extends; a plurality of supporting intermediate structures for supporting the cable between the upstream station and the downstream station; a plurality of transporting units coupled above the cable in a configuration suspended in the void and free to swing; an alarm device configured for detecting the contact between the transporting units and the supporting intermediate structures when a threshold tilting angle of the transporting units is exceeded and for emitting a relative alarm signal.
