This slope analysis shallconsider the maximum and minimum

21、operational design con-ditions such as ride vehicle, live load, belt wear, expected waterfrom the ride, and environmental conditions.6.2.5.2 Type 2 Walk On/Off ConveyorThe maximum slopeshall be determined by ride analysis and shall not exceed thefollowing limitations:(1) The angle of inclination fro

22、m the horizontal shall notexceed 3 within 36 in. (0.92 m) of the ingress and egress ends.(2) At the vehicle load position, the slope of the conveyorshall match the slope of vehicle travel at the load position.(3) For conveyors running up an incline the angle ofinclination of the conveyor shall not e

23、xceed 18 at any point.For conveyors intended to be accessible the inclination shallnot exceed 10 at any point.(4) The ride analysis for declining conveyors shall considerthe slope of the conveyor, the deceleration rate under brakingand the patron restraints.6.2.6 Maximum Cross Slope2%.6.3 Patron Res

24、traint, Clearance Envelope, and Contain-ment Design Criteria:6.3.1 RestraintsThe designer/engineer shall consider ac-celerations generated by the conveyor system in the rideanalysis.6.3.2 Clearance Envelope:6.3.2.1 Type 1 Riding Position Conveyor:(1) The clearance envelope shall be determined based

25、onthe “Patron Clearance Envelope Analysis” as outlined insubsection 6.6 of Practice F2291.(2) If the pathway of the conveyor belt is used for emer-gency evacuation egress, then the minimum head room shallmatch the value listed in 6.3.2.2(2).6.3.2.2 Type 2 Walk On/Off Conveyor:(1) The clearance envel
