A protection device for traversing a guide member and method of making the like, the protection device includes a wheel configured to engage the guide member. In some embodiments, the protection embodiment includes a locker configured to engage a braking surface. The locker engagement mechanism configured to releasably engage the locker. In some embodiments, a centrifugal actuator operatively coupled to the wheel and configured to actuate the locker engagement mechanism to release the locker based on a threshold speed of the wheel. In an instance in which the wheel is rotating at or above the threshold speed of the wheel in a first direction, the centrifugal actuator is configured to actuate and rotate the locker engagement mechanism to release the locker and to allow the locker to rotate and engage the braking surface. A corresponding method of operation is also provided.

A railway vehicle, including an emergency braking device including at least one brake module, wherein each module includes a contact element intended to be in contact with the ground at the moment of braking, and movable between a retracted position and a deployed position in which the contact element is in contact with the ground and is able to slow down the moving railway vehicle by applying a pressure force to the ground, and at least one control unit that is capable of communicating commands to the brake module, wherein the control unit is able to communicate to the brake module the command to deploy the contact element to its deployed position when at least a portion of the vehicle leaves the track on which the vehicle is traveling.

The frame brake assembly includes a sleeve, a piston, a brake, and a retracting device. The piston translates within the sleeve between an upper first position and a lower second position. A brake is coupled to a lower portion of the piston beneath the sleeve. As the piston moves between positions, the brake moves in a corresponding manner. In the second position, the brake is lowered into contact with the ground. The retracting device is used to automatically return the piston and brake to the first position. When installed on the coiling machine, the frame brake assembly is coupled to the frame of the coiling machine and is in selective engagement with a pair of spool arms. Rotation of the spool arms induces translation from the first position to the second position in the frame brake assembly.

An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The exercise machine may include a compact and safe counterbalancing gas spring mechanism that tends to move the exercise device away from the exerciser, and that requires a force to be applied to move an exercise device down towards the exerciser. The exercise machine may include an exercise device that is rotatable along a vertical axis, and may be coupled to an adjustable monitor for a wide range of uses. The exercise machine may be used by a exerciser lying supine, sitting in a chair or wheelchair, or standing in front of or adjacent the exercise machine.

A foot pedal assembly and method of moving a wheel assembly from a stowed configuration to a deployed configuration is provided. The foot pedal assembly can be moved to a locked configuration, thereby securing the wheel assembly in a deployed configuration, by allowing a foot pedal of the foot pedal assembly to move away from a second position after moving the foot pedal from a first position to the second position. When in the locked configuration, the foot pedal assembly can be moved to an unlocked configuration by moving the foot pedal assembly back to the second position, thereby allowing the foot pedal assembly and the wheel assembly to move towards the first configuration and the stowed configuration, respectively. A pin extending from a cam assembly into a raceway of a raceway body travels through the raceway as the foot pedal assembly is moved between configurations.
