A system for physical mobility activity of a person includes at least one fixed support member and at least one contact member to be worn by a person in motion. The support member and the contact member include at least one support surface and at least one contact surface, respectively. The support surface and the contact surface constitute the respective components of a hook-and-loop fastening connection including of hooks and loops, wherein the hooks have hook stems and hook openings. The hook openings on the support surface or contact surface in question are at least substantially all situated at the same side of the hook stems in question, when considered in a first direction parallel to the support surface or contact surface in question.

The tandem pulley comprises a pair of sheaves mounted in line between first and second flanges. A gate is fitted rotating with respect to the first flange between closed and open positions. The gate comes into contact with the second flange in the closed position to close a housing. The clamp is movable in rotation on the gate between a locking position locking the gate in the closed position and an unlocking position. The clamp has a prong pressing on the first flange and the gate in the locking position. The clamp has an actuating area separated from the first flange by the gate. Rotation of the actuating area from the locking position to the unlocking position corresponds to a movement of the actuating area away from the second flange. Rotation of the actuating area results in pivoting of the prong.

A tandem pulley includes a support bracket having the shape of an inverted U. The support bracket defines a through hole. A pair of sheaves is arranged in line inside the support bracket. Each sheave is mounted rotating freely around a spindle fixed to the support bracket. A carabiner is fitted in the through hole. A connector is configured to connect the support bracket with the carabiner. The connector is configured in such a way as to allow rotation of the carabiner around an axis parallel to the spindles of the pair of sheaves. A spring is connected to the support bracket, the spring being arranged to exert a force on the carabiner biasing the latter to a rest position by rotation of the carabiner.

A first conveyance arrest system includes a trolley 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 trolley arrest cylinder. The trolley arrest cylinder comprises a port that vents pressurized fluid within the trolley arrest cylinder and provides a vent resistance to fluid escaping the trolley arrest cylinder. A second conveyance arrest system includes a conveyance trolley slideably coupled to a conveyance guide, and a trolley 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 trolley arrest cylinder in response to movement of the trolley toward the conveyance stop.

For travel on a cable, the zipline trolley includes a wheel, a brake, a frame, a hanger, and a lower slot. The wheel is disposed on a proximal end of a frame. The wheel includes a groove that receives a cable at a lower portion of the wheel and a wheel bearing. The brake is disposed on a distal end of the frame. The brake is connected to a given lever point and includes a groove along a brake bottom that receives the cable. The frame includes an array of lever points disposed between the brake and the wheel. The hanger is connected to a given lever point and suspends a weight. The weight applies a force about the wheel to the brake to control a rate of descent of the device along the cable. The lower slot receives the cable.

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 moving climbing wall surmounts an upper roller and a lower roller. One of the rollers is connected to a power source for movement of the moving climbing wall around the rollers. A controller controls the power source.
