1、SledBallast滑车压载物Weightcanbeaddedorsubtractedfromthesledtomaintainadesiredconstantsledweight.可以给滑车增加或减少加载物以保持期望的恒定滑车重量。PneumaticAccelerator气动加速计Thesystemusespressurizedairtopropelthesledtodesiredvelocities.Accuracywithin0.5%andrepeatabilitywithin0.25%aretypical,andnocivilwor

2、kisrequiredforinstallation.Firingpressureisremotelymonitoredandautomaticallymaintained.该系统是利用压缩空气驱使滑车获得期望的速度。精确度在5%以内重复性在0.25%以内，安装时无需基建设施。点火压力是遥控的并自动保持。LightingSystemsSeattleSafetymanufacturesoverheadlights,portablefloorlights,andportableadjustable-heightlightsforimpactzon

3、eillumination.Webuildbothtraditionalincandescenttungsten-halogenandmodernflicker-freemetal-halidesystems.照明系统SeattleSafety公司生产高架照明灯，便携式落地灯和便携式可调高度照明灯用于碰撞区域的照明。我们生产传统的白炽卤钨灯和现代的无闪烁卤化金属灯。ReactionBlock反应块Thesystemreactionblockisfullybelowgrade,reducingsiteimpactandcivilworkcost

4、.Sledrelocationtoanewsiteisgreatlysimplified.此系统反应块完全在地下，减少了场地冲击和基建费用。滑车更换到新场地也变得很容易。Decelerator减速器Thedeceleratoremploysmildsteelrodsasanenergyabsorbertostopthesled.Setuptypicallytakes15minutes,andtherangeofachievablepulsesisexceptionallywide.Acomputerprogramissuppliedtodet
