A cross connection facility (Figure 2. 2. (1)) is provided on the launcher to allow
another suitable hydraulic system to be connected to the DSB launch vehicle in the
event of the hydraulic pump or engine failing. This allows the launcher to complete its
mission at a lower speed.
Launch Beam Lifter and Module Lifting Beam
The lifting equipment is dedicated to its particular function (either launch beam or
parallel/ramp module transfer) and is not interchangeable. The smaller launch beam
lifter, used for the launch beam modules, is of fixed geometry and is suspended from
the crane hook via a 6 ft 6 in (2 m) extension sling during operation.
The larger module lifting beam, used for the parallel modules, also attaches to the
crane hook via a 6 ft 6 in (2 m) extension sling and has a three-position configuration.
Two arms at each end of a central beam are held in one of three positions by quick-
release shootbolts. The positions of the arms are dependent on use, module
deployment, module folding or stowage of the lifting beam itself.
