Device specification fairground rides

Cancelled many lag terms, and also added a number of requirements. The main change is embodied in five aspects. First, the sliding type, such as the "roller coaster" increased acceleration permissible value. Coffee Cup Ride is because when the "roller coaster" down from the highest to the lowest, the speed is very fast, the acceleration greatly, in order to make by people not to be hurt, acceleration should be limited in a certain range. Second, an increase of various loads, such as wind load, fairground rides because when the wind at six level and above, the velocity coupled with the impact force, have been thrown out may take, is very dangerous, you must stop the recreation facility operation. Third, the safety coefficient of the adjustment, reduced. Originally an ordinary material can achieve the security requirements, attraction rides  is no need to use special materials. While the previous safety coefficient is set too high, resulting in increased material waste and cost. Fourth, an increase of safety assessment and safety analysis of the new requirements. Fifth, fairground rides an increase of water recreation facilities safety standards.
