Binary loadlifters were low-level labor droids that functioned in a cargo loading capacity. Binary loadlifters were one of the best examples of the pre-Republic droid inventions in the murky history. Most load lifters had two strong hydraulic limbs which could slide underneath crates and other cargo, although some had strong grasper-like claws for smaller cargo. Each droid sported yellow markings as a caution system. All loadlifters had a single photoreceptor that doubled as a cargo code reader. Behind the photoreceptor was a binary broadcast antenna, and below that was a repulsorlift counterweight, which helped the droid with particularly heavy loads. Two wide magna-pod feet and hydraulic durasteel limbs enabled the droid to be remarkably stable when lifting or moving cargo.
