Fall control system and method of controlling a movement during fall event

A fall control trolley for moving along an elongate guide rail comprising, a body, a background speed controller coupled to the body, and a speed controller coupled to the body, the background speed controller for engaging with one or more speed control track when the trolley is mounted on a guide rail and in a travelling orientation, the background speed controller selected from the group of one or more than one background magnet, one or more than one background pre-tensioned gear, one or more than one background on-set wheel, and a combination thereof, the background speed controller for controlling the speed of the trolley along the elongate guide rail in the travelling orientation to not exceed a maximum walking speed;

• the speed controller for engaging with the one or more than one speed control track, when the speed controller is displaced from a first position, when the trolley is in the travelling orientation and the speed controller is not engaged with the speed control track, to a second position when the trolley is in a falling orientation and the speed controller is engaged with the speed control track, the speed controller selected from the group of one or more than one magnet, one or more than one pre-tensioned gear, one or more than one on-set wheel, one or more than one off-set wheel, a wave-like surface on the body of the trolley, a flat surface on the body of the trolley, and a combination thereof, the speed controller for controlling the speed of the trolley along the guide rail in the falling orientation to not exceed a maximum fall speed;
• the maximum walking speed being greater than the maximum fall speed, and the maximum walking speed and the maximum fall speed being greater than zero.

A method for controlling a movement of a movable object during a fall event, the method comprising:

• (a) coupling a first end of a tether to a trolley, the trolley being moveable along an elongate guide rail extending along an axis, the trolley comprising a background speed controller and a speed controller, the background speed controller active while the trolley is in a first position, in a travelling orientation, and the speed controller active when the trolley is in a second position, in a falling orientation;
• (b) coupling a second end of the tether to the moveable object;
• (c) exerting a pulling force, through the tether, on the trolley that is sufficient to move the trolley along the elongate guide rail while in the travelling orientation, the background speed controller controlling the speed of the trolley along the elongate guide rail to not exceed a maximum walking speed;
• (d) during the fall event, exerting a falling force, through the tether, on the trolley that is sufficient to displace the trolley from the first position to the second position, the speed controller for controlling the speed of the trolley along the guide rail in the falling orientation to not exceed a maximum fall speed;
• and
• (e) allowing the moveable object to descend to a ground at a controlled speed, wherein the maximum walking speed is greater than the maximum fall speed, and the maximum walking speed and the maximum fall speed are greater than zero.
