Grandstand

摘要

The extending grandstand has a telescopic structure. The rear supports (10,10a), at the step sections (2-5) after the first section (1), are supported by legs (11) on the ground (8) when deployed. Adjacent step sections have lifters (23) to raise and lower their sections as the grandstand is moved out for use, and back after use. When fully retracted, the support feet are clear of the ground.
