A stop for stopping a trolley on a rail is described. The trolley comprises a set of wheels, including a first wheel and the rail provides, at least in part, a running surface, including a first portion and a second portion thereof, for the first wheel. The stop comprises an actuator providing a third portion of the running surface between the first portion and the second portion and an arm, coupled to the actuator. The stop is arrangeable in a first configuration, wherein the arm is arranged to block the trolley therepast. The stop is arrangeable in a second configuration, wherein the arm is arranged to allow the trolley therepast. The stop is arranged to move from the first configuration to the second configuration by actuation of the actuator, preferably by a movement of the actuator in a direction transverse to the third portion of the running surface.

A compact braking system for zip-line that brakes a sliding car including an anti-return trapping device that traps the sliding car preventing its return by a zip-line cable and a braking device that transfers and dissipates the energy of the arrival impact of the slide car without the use of one or more cables and/or elements external to it and without the activation of any operator.

For zipline spring segment, the spring segment includes two spring sub-segments, an end cap, and a guide. The two spring sub-segments each include a set of spring coils, each spring coil set including a large diameter end and a small diameter end, wherein each of the spring coils of the spring segment nests completely within a neighboring spring coil and a cable passes through the spring coils. The end cap is disposed on the large diameter end of the spring coils, the end cap including a hole that receives the cable. The guide connects the two sets of spring coils of the spring sub-segments at the small diameter ends. The guide guides the cable through a center of the spring segment, wherein the guide and the end caps are configured to be in contact upon a full compression of the spring coil segment.

Described herein are latching devices where relative speed of movement between members is in part controlled or reduced via eddy current formation and in part controlled or relative motion stopped via a latch arrangement. Various embodiments are described, one being use of a conductive member; at least one magnetic field and a latch member that, prior to latching, moves independently to the at least one conductive member. A kinematic relationship exists between the conductive member and at least one magnetic field that enables the conductive member to move at a different speed relative to the magnetic field on application of an energizing force, thereby inducing an eddy current drag force by relative movement of the conductive member in the magnetic field. The eddy current drag force resulting causes movement of the conductive member causing the conductive member to engage the latch member thereby halting movement between the at least one conductive member and the at least one latch member.

A rescue device includes a pulley includes a support flange with two rotation shafts mounted salient and extending in a first direction. Two sheaves are mounted rotatable around two rotation shafts to define a running line of a cable. Two flanges are mounted rotatable between a first position and a second position. A first blocker is configured to present a first position blocking the first flange in the closed position and a second position allowing rotation of the first flange. A second blocker is configured to present a first position blocking the second flange in the closed position and a second position allowing rotation of the second flange. The second blocker is independent from the first blocker.
