The system includes a body, an upper brake pad coupled to the body and configured to contact a side of a flange of the beam and a lower brake pad coupled to the body and configured to contact an opposing side of the flange, and an actuator coupled to at least one of the brake pads and configured to move the brake pads between a gripping position that grips the flange and an open position that spaces one of the brake pads away from the flange. ## Claims ### Claim 1 A traverse system configured to move a catwalk relative to a beam, the system comprising: a body; an upper brake pad coupled to the body and configured to contact a side of a flange of the beam and a lower brake pad coupled to the body and configured to contact an opposing side of the flange; and an actuator coupled to at least one of the brake pads and configured to move the brake pads between a gripping position that grips the flange and an open position that spaces one of the brake pads away from the flange. ### Claim 2 (depends on 1) The system of claim 1, wherein the open position comprises a dimension measured between the brake pads that is equal to or greater than a mill tolerance of the flange. ### Claim 3 (depends on 1) The system of claim 1, wherein the upper brake pad is coupled to an actuator and a spring mechanism. ### Claim 4 (depends on 3) The system of claim 3, wherein the spring mechanism comprises a plurality of washers. ### Claim 5 (depends on 3) The system of claim 3, wherein the spring mechanism is tensioned in both of the open position and the gripping position. ### Claim 6 (depends on 1) The system of claim 1, further comprising: a hydraulic cylinder coupled to the body. ### Claim 7 (depends on 6) The system of claim 6, wherein the hydraulic cylinder includes two rods extending between the body and a frame of the catwalk. ### Claim 8 A catwalk system for transferring tubulars, the catwalk system comprising: a frame for supporting the catwalk; a beam table comprising a plurality of spaced-apart beams that supports the frame; and a brake device for moving the frame relative to a flange of one of the beams, the brake device comprising: a brake body comprising a housing having a slot formed therein that is sized greater than a thickness of the flange; an upper brake pad for contacting a side of the flange and a lower brake pad for contacting an opposing side of the flange disposed in the brake housing; and an actuator coupled to at least one of the brake pads for moving the brake pads between a gripping position that grips the flange and an open position that spaces one of the brake pads away from the flange. ### Claim 9 (depends on 8) The system of claim 8, wherein the open position comprises a dimension measured between the brake pads that is equal to or greater than a mill tolerance of the flange. ### Claim 10 (depends on 8) The system of claim 8, further comprising: a hydraulic cylinder coupled to the brake body. ### Claim 11 (depends on 10) The system of claim 10, wherein the hydraulic cylinder includes two rods extending between the brake body and the frame. ### Claim 12 (depends on 8) The system of claim 8, wherein the upper brake pad is coupled to an actuator and a spring mechanism. ### Claim 13 (depends on 12) The system of claim 12, wherein the spring mechanism comprises a plurality of washers. ### Claim 14 (depends on 12) The system of claim 12, wherein the spring mechanism is tensioned in both of the open position and the gripping position. ### Claim 15 A method for moving a frame relative to a drill floor, the method comprising: providing a frame; providing a plurality of spaced-apart beams that support the frame, each of the beams having a flange and a longitudinal length positioned substantially normal to a longitudinal length of the frame; and moving the frame along the longitudinal length of one of the beams by gripping one of the flanges with a brake device. ### Claim 16 (depends on 15) The method of claim 15, further comprising: moving the brake device relative to the one of the beams and the frame. ### Claim 17 (depends on 16) The method of claim 16, wherein the brake device comprises an upper brake pad contacting the flange and a lower brake pad adapted to contact an opposing side of the flange, and the moving the brake device further comprises: actuating a hydraulic cylinder that is operably coupled to one of the brake pads to move the brake pads to an open position. ### Claim 18 (depends on 17) The method of claim 17, wherein the open position comprises a dimension measured between the brake pads that is equal to or greater than a mill tolerance of the flange. ### Claim 19 (depends on 17) The method of claim 17, wherein the brake device comprises a spring mechanism that is tensioned in both of the open position and a gripping position. ### Claim 20 (depends on 16) The method of claim 16, wherein the brake device comprises a hydraulic cylinder having rods extending therefrom to opposing sides of the frame, and the moving the brake device further comprises: actuating the cylinder to extend or retract one of the rods.
