For the purposes of this document, the terms and definitions given in GB/T 20306 and the following apply.
3.1
merry-go-round series
merry-go-round type of rides with the turning table of the equipment rotates around the central vertical column, and the ride system is installed on the turning table and ups and downs along with a certain stroke
3.2
rotating cup series
merry-go-round type of rides with the turning table of the equipment rotates around the central vertical column at a fixed angle, and the ride system is installed on the turning table to spin
3.3
rotating express series
merry-go-round type of rides with the ride system of the equipment rotates around the central vertical column and along the ups and downs of the track
3.4
other merry-go-round series
merry-go-round type of rides with the ride system of the equipment rotates around the central vertical column and is accompanied by other forms of movement, but it does not belong to those as defined in 3.1, 3.2 and 3.3
3.5
fail-safe
a mode of avoiding larger failures or accidents in which the control system or mechanical mechanism system of the equipment is able to maintain or transfer to a safe state after a failure of the equipment.
3.6
