A play structure having one or more monolith structures for the connection of other surfaces (e.g., deckings, water-based elements, interactive elements, etc.). Each of the monolith structures may be adjustably connected with a ground surface such that a variety of possible angles may be obtained by the monolith with respect to the ground surface. After the desired orientation of the monolith is obtained to the ground surface via the adjustable connection, the monolith may be secured in such position. Water or other fluid may be provided to the monolith structures via piping that interfaces with the monolith structures by a fluid connection that is in communication with piping disposed within the monolith structures. A fluid dumping or delivery system (e.g., based upon a tipping element that provides water to a fluid flowing surface and/or other water dispersion element) may be provided as part of the play structure.

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.

A portable zip line emergency brake system intended to stop or slow down a zip liner (or load) on a cable while giving the control to the device user or operator on the opposite end of the zip line. As an out of control rider comes down the zip line the operator will lock the device onto the cable and roll it out onto the zip line using a combination of sending force by the operator and gravity to meet the rider's pulley. The device is adjustable for different riders' estimated weights. Once the rider's pulley comes in contact with the device far out on the cable it will use a lever camming action between two brake pads on the cable as it reverses direction. As the brake is engaged it will stop or slow the rider. The operator can then pull the rider to the end safely.

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.

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.

An amusement ride requires the participant to ascend to a platform for the beginning of the amusement ride via a single or a double helix ladder. The participants are tethered for safety. Operators attend the tether lines. The tethers also can run through belays for safety.
