MAJOR COMPONENTSThe components of a mainline GM4000 switch machine are described in the followingparagraphs and shown in Figures 1-1 and 1-2.CoversThe GM4000 has three light-weight aluminum covers, as shown in Figure 1-1, that protectinternal switch machine components from unwanted debris, water, or other material. Thesecovers are attached to the switch machine by a hold-down on the housing and a removable strapthat can be locked. An AAR wrench is required to remove or secure the straps that hold downthe center and end covers. The covers are removable and can be utilized as a tray to holdhardware or tools during maintenance.To remove a cover, a pivoting and upward pulling motion is required. The end covers attach tothe housing by slipping the thick cover lip underneath the 3/8-inch diameter rods on either end ofthe housing and pivoting cover down to allow housing wall to be captured by the gasket grooveof the cover.GuardsGuards of the GM4000, as shown in Figure 1-1, protect the space for lateral movement of thethrow bar, lock rod, and point detector rod by keeping away unwanted trackside debris, ballast,or other material.Latch Stand ModuleThe latch stand module, as shown in Figure 1-1, is a support fixture and most importantly, alocking fixture for the hand throw lever and selector lever. The module bolts directly to theswitch machine housing. The latch stand accommodates right or left hand switch machineconfigurations.Hand Throw ModuleThe hand throw module, as shown in Figure 1-1, is a manual means of switching tracks withoutelectrical power. While in a hand throw mode, the switch machine can complete stroke, lockswitch points, and indicate normal or reverse position.P2444, Rev. Jan/07 1-4ALSTOM Signaling Inc.
