Mechanical Assemblies 3
HORIZONTAL CROSS ARM
OVERVIEW
The Horizontal Cross Arm assembly allows the forward mechanics to be
manually extended approximately 8 inches (20 cm). Extension and retraction can
be accomplished by releasing the cross arm brake, grasping the handle mounted
at the end of the cross arm and manually positioning the cross arm in the desired
location.
Position indicator labels that indicate the length of extension can be found on two
recessed areas of the cross arm. Tick marks indicate each centimeter and
numbers occur in 5 cm increments to a maximum of 20 cm.
HORIZONTAL CROSS ARM BRAKE
The Horizontal Cross Arm brake may be engaged to prevent the cross arm from
moving. When the brake is engaged a brake pad restricts movement of a bearing
in the Cross Arm Housing which in turn prevents the cross arm from moving.
Refer to Figures 1 and 2.
To remove the brake, perform the following:
1. Remove the hole plug.
2. Remove 1 Torx screw securing the Cross Arm Brake Handle.
3. Remove 2 Torx screws from the bottom of the Cross Arm Lower Cover.
4. Lift the Cross Arm Center Cover up carefully and set aside.
5. Remove 4 Torx screws that secure the Cross Arm Brake Mount to the
housing.
6. Remove the Cross Arm Brake Pad.
