Carriage Manifold

TM 5-5420-279-23

carriage manifold from the launch chest pack, which allows independent control of the forward

carriage to inspect or renew the steel wire ropes.

1-10-25 Carriage Manifold

The carriage manifold is a multi-slice solenoid valve block weighing approximately 110 lb. (50 kg).

The carriage winch `slice' directs hydraulic fluid flow to the forward or rear carriage drum winch

and directs a selected reduced pressure to the other drum winch to maintain the tension in the

steel wire ropes of the drum winches. The `slice' incorporates crossline relief valves to protect the

drum winches. The individual solenoid valves of the carriage manifold are equipped with

`mushroom button' manual overrides, complete with securing clips, to select the required carriage

function should electrical failure occur.

1-10-26 Far Bank Support

When the launch beam is fully deployed and reaches the far bank, it is lowered as

necessary to accommodate the height difference between the two banks. The launch beam is

supported at its deployed end (opposite end to the launcher vehicle) by the far bank support

before launching of the bridging modules commences.

The far bank support comprises a central telescopic column, bottom pivot beam and two

30 in. (0.75 m) diameter ground bearing pads supported at the ends of the 5 ft (1.5 m) long pivot

beam. The ground support pads are carried separately from the beam and are installed prior to

deployment of the launch beam.

The beam pivots about the bottom of the telescopic column which is connected to the

forward launch beam. As the far bank support lands on the far bank the pivot beam rotates about

the end of the telescopic column to accommodate any cross slope of the bank.
