SALs, or Servo-Actuated Loaders, were a form of limited-sentience maintenance and heavy-lifting droids employed in the construction of New Atero and other structures on New Spherus Magna. They are a leftover of the Great Beings, and are seldom given much consideration by the various people of the planet.
SALs are known for their distinctive skeletal appearance and large forklift-like hands.
SALs were never intended to be deployed in any combat or conflict-heavy situations, and as such, their design leaves systems relatively exposed. While sealed against dust and other contaminants, it is not difficult to disable a SAL by cutting their joint-actuating cables.
SALs are, in many loading docks and foundries, indispensable to the Matoran and Agori. Nearly as tall as a Toa, and easily as strong, if not stronger, they can shift loads and support weights that would otherwise require teams of regular workers.
SALs are possessed of limited sentience, and as such are treated with kindness by most workers. There are, however, those who treat them as mere machines, worthy of neither respect nor care.
A distinct feature of the SAL design is the shin-mounted shock dampeners. Fixed springs in the shins absorb a degree of the kinetic energy that might be encountered if a sudden load was dumped onto a SAL. This preserves the shin components, rather than letting them be shattered under shock force.
