1-10-32 Ramp End Beam

The ramp end beam is a rectangular welded box section, which is positioned in an aperture at the

tapered end of each ramp module. It includes bridge lifting points through which the forward

carriage straps are routed and it also provides mounting for the bridge approach ramps. Fixed

pins within the aperture of the ramp module locate on the end beam as the ramp module is

lowered down onto it and side guide pads aid alignment of the lower holes. The end beam is

secured to the ramp module at its lower edge by insertion of twist-to-lock pins.

1-10-33 Parallel Modules

The parallel modules are individually identified by a serial plate on one compression face of

the parallel panels and have an overall length of 20 ft (6.132 m) and each consists of six

transverse deck units attached at 24 hinge points to two longitudinal parallel panels.

The modules are hoisted from two slinging points on the outboard side of each parallel

panel during deployment and from similar slinging points on the inboard side for retrieval. Two

dampers are attached to each parallel panel and the transverse deck units to control the rate of

folding/unfolding during bridging operations.

Three curb plates are hinged on each side of the module and are lifted and dropped into

position during bridge deployment. Each center curb plate houses a bridge marker flag which is

raised into the vertical position for traffic guidance after bridge deployment.

When in the folded condition, the modules are 8 ft (2.447 m) wide (over the nibs) and 14 ft

(4.298 m) wide when deployed, but without the three curb plates deployed. The compression
