A deployment arangement comprises an inner tube 10 pivoted to ground at `P` and carrying an outer tube 12 for telescoping movement. The inner end of the outer tube 12 carries a collar assembly 14 which is pivotally connected to a drive or radius arm 18 which is pivoted to ground at `Q`. The radius arm 18 carries a drive plate 50 which defines a cam track in which a cam follower runs. The mechanism is driven by a ram 20. On actuation of the ram 20, the consequent rotation of a drive plate relative to the collar assembly 14 initially executes a programmed rotation of the outer tube 12 about its longitudinal axis and then locks the outer tube against rotation. Thereafter, the outer tube 12 extends telescopically relative to the inner tube and the inner tube pivots about `P`.
