| 摘要 |
A vertical support system includes a first articulated leg assembly configured to carry a first load, the first articulated leg assembly being selectively movable between a first retracted configuration and a first loaded configuration and a second articulated leg assembly configured to carry a second load substantially kinematically identical to the first articulated leg assembly, the second articulated leg assembly being selectively movable between a second retracted configuration and a second loaded configuration, wherein a lateral width ratio is equal to a value of less than about 0.6, the lateral width ratio being defined as a ratio of (1) a maximum lateral width when the first articulated leg assembly and the second articulated leg assembly are in a retracted configuration to (2) a maximum lateral width when the first articulated leg assembly and the second articulated leg assembly are in a loaded configuration. |
