A first conveyance arrest system includes a conveyance arrest cylinder comprising a piston rod mechanically coupled a trolley receiver. The trolley receiver engages a conveyance trolley, displaces the piston rod and pressurizes a working fluid within the conveyance arrest cylinder. The conveyance arrest cylinder comprises a port that vents pressurized fluid within the conveyance arrest cylinder and provides a vent resistance to fluid escaping the conveyance arrest cylinder. A second conveyance arrest system includes a conveyance trolley slideably coupled to a conveyance guide, and a conveyance arrest cylinder mechanically coupled to the conveyance trolley. The second conveyance arrest system also includes a conveyance stop configured to engage a stop engagement end of a piston rod and thereby pressurize fluid within the conveyance arrest cylinder in response to movement of the trolley toward the conveyance stop.

Described is a carriage (1) for moving on a cable and/or rail comprising: a wheel (2) equipped with its own rotation shaft (3) and configured to rotate on a cable (C) and/or rail; braking masses (4) positioned parallel to the wheel (2) and made of non-magnetic material; magnetic masses (5) configured to generate a magnetic field; and a self-adjusting device (6), connected to the braking masses (4) and positioned inside the rotation shaft (3) of the wheel (2), configured for moving the braking masses (4) close to the magnetic masses (5) along a direction (D) parallel to an axis of extension of the rotation shaft (3), as a function of an increase in a speed of rotation of a wheel (2), in such a way that the magnetic masses (5) generate eddy currents by electromagnetic induction defining a slowing force proportional to the feed speed of the carriage (1).

In an overhead line system, a first moving device is movable in the air between a first support post and a second support post. A first overhead line is stretched from the first moving device and connected to the first lifting device via the first support post. A second overhead line is stretched from the first moving device and connected to the second lifting device via the second support post. A second moving device is movable in the air between a third support post and a fourth support post. A third overhead line is stretched from the second moving device and connected to the third lifting device via the third support post. A fourth overhead line is stretched from the second moving device and connected to the fourth lifting device via the fourth support post. A suspension device is connected to the first moving device and the second moving device.

An exemplary embodiment of the present disclosure provides a robot comprising a body, a processor, and a memory. The memory further comprising instructions that, when executed by the processor cause the body to engage a first wire to support the robot from the first wire, traverse the first wire, engage a second wire simultaneously while engaging the first wire, the second wire branching from the first wire, then after engaging the second wire, disengage the first wire and traverse the second wire.

The zip line rail system can be connected to a challenge course, a zip line, a zip track system, or any combination thereof. The zip line rail system of the present invention can have two rails that a member slide's two wheels rollably engage with, and the zip line rail system can be configured in any of a variety of directions.

For A zip line trolley brake system includes a cable suspended between upper and lower support platforms which, together, function with rider harnessing, loading, and take-off with a passive braking trolley allowing a controlled descent and barrel spring system providing addition braking near the end of a cable termination. The zip line trolley positioned atop a cable includes a frame assembled from a pair of parallel side plates, a four-sided rotational brake pad, and a parabolic groove wheel which is sandwiched between side plates, and a lever. A lever from which a rider is suspended, can be pinned anywhere within the trolley's circular toothed slot instilling a brake force for the cable slope. A trolley brake generally square sides are grooved for cables and fabricated from a durable polymeric material is rotatably within affixed side plates. A spring system includes a football-shape springs, spring spacers, bump spring spacer receiver, and a locking inserts designed to fasten the springs and allow the springs to collapse within themselves reducing the compression length. A bump spring spacer receiver makes contact with the zipline trolley further decelerating the suspended rider as contact is made with the springs.

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.
