Figure 3-9 End Truck Assembly & Installation
3.3.6 End Truck Assembly & Installation – Here the assembly of the end trucks is completed and they are
installed onto the runway. Orientation of the end trucks on the runway is important. Make sure you put
each end truck onto the runway so that the hole in the end bracket for the brace is on the inside of the
runway (see Figure 2-2).
 Underhung – apply the following steps for each end truck:
- Disassemble a frame from the end truck.
- Place the frame with the end brackets still attached to it onto the runway beam so its wheels
ride on the lower flange of the runway beam in accordance with the Underhung part of Figure
3-9.
- In the same manner place the other frame on the opposite side of the runway beam and
reassemble this frame to the end brackets, again in accordance with the Underhung part of
Figure 3-9.
