Specifications, overall (for reference) and mounting dimensions, as well as a general view of the bridge are shown in Table 1 and Fig. 1,2 and 3. The bridge in Fig. 3 differs from the bridge in Fig. 1 location of the shock absorber (vertical). The vertical arrangement of the shock absorber reduces the force by moving the bridge.
