摘要： A power-actuated parking brake is provided that produces sufficient force to set a parking brake for a locomotive. A powered drive train rotates a sheave over which a brake chain is positioned. Rotation of the sheave draws up the brake chain that is connected at one end to the parking brake. The parking brake is set when sufficient tension is applied to the brake chain by the powered drive. The drive train includes a drive shaft driven by an electric motor and connected to the sheave through a planetary reduction drive and a clutch.

摘要： The temporary rail bridge (20) of the illustrated embodiment includes a bridge number (20) that is coupled to a track rail (16) by screw clamps (24). Each of the screw clamps (24) includes an internal tensioning component such as a spring (58) that allows for fast installation of the rail bridge (20) and maintains continuous pressure engagement in operation. The rail bridge (20) reduces track closure time due to rail damage and associated costs and inconvenience.
