关键问题

在此模块中回答了以下关键问题：

谁开发与设计，施工和使用车载空中设备相关的标准？
美国国家标准研究所（ANSI）和加拿大标准协会（CSA）制定了与车载空中设备的设计，施工和使用相关的标准。

什么是空中设备？
空中设备是指任何主要设计和用于定位人员的可伸缩、可连接或两者兼而有之的设备。

堕落逮捕系统的目的是什么？
防止跌倒系统是为了在跌倒开始后阻止跌倒。

什么是手套工作?
戴手套工作是在带电导体和设备中进行带电工作的一种方法，工人们戴着特殊的绝缘手套，有时还戴着绝缘套管。

使用车载空中装置的主要危险是什么?
主要危险是翻倒、从平台或梯子上掉下来、碰撞、触电和坠落物体。

样本视频成绩单

以下是为此模块提供的视频示例的成绩单：

用于车载的航空设备的ANSI和CSA标准包括以下设计要求：•工作平台必须在各个方面具有护栏和中间导轨，或完全封闭，高度为39到45英寸（0.99和1.14米）。•必须在所有侧面提供至少4英寸（102毫米）的托盘或踢球板，但入口处除外。•必须在悬臂，平台或平台安装上提供能够承受3,600 LBS（16,000牛顿）静力的锚固，以获得允许数量的乘员。•必须在降低或收起位置提供平台接入，并且可以使用灵活的门和链条固定高达30英寸（762毫米）的开口。•必须提供在运输或旅行期间固定动臂或平衡梯形的方法。必须固定锁定引脚以防止无意的脱离和损失。•绝缘篮和铲斗必须由非导电材料构成，不具有任何孔或开口，并根据适用的标准进行介电完整性。•必须由非导电材料构造出用于绝缘衬垫的非绝缘铲斗和篮子，或者能够与吊杆盖板覆盖并被识别为非绝缘材料。衬里必须由非导电材料制成，不具有任何孔或开口，并根据适用的标准进行介电完整性。•不绝缘铲斗和没有衬垫的篮子可以由导电或非导电材料构成并且具有孔或开口。 They must be identified as non-insulating. •A slope indicator on the unit must be visible to the operator during set up. For mobile units, slope must also be indicated in the cab. Allowable slope limits must be indicated on the unit and in the manual. •The device must remain stable (i.e., not overturn) in all possible positions while sustaining a load 1-1/2 times its rated capacity on firm level ground, and 1-1/3 times its rated capacity on a 5 degree slope. •If stabilizing devices are a design requirement, they must be utilized during load stability testing. •Hydraulic components whose failure could result in movement of the platform, material lifting device, or both must have a minimum bursting strength at least 4 times the maximum design pressure. •Other hydraulic components typically rated for burst must have a minimum bursting strength 3 times the maximum design pressure. If a component is rated by another metric, the minimum bursting strength must be 2 times the maximum design pressure. •Platform "creep" or "drift" (downward movement) must not exceed 4 inches per hour, plus any applicable height allowance, when hydraulic cylinders are fully extended and loaded. •All movements must stop if there is a loss of power or a hydraulic line fails. •Hydraulic systems must meet requirements related to venting, fluid reservoir level indication, fluid cleanliness, cylinder loading, securement of threaded elements, and pressure control. •If stabilizing devices are a design requirement, an interlock device must prevent all boom movements until after these devices are deployed. The interlock is intended as a reminder. It can be temporarily overridden and disabled, as long as it is reset before the next set up of the device. •If oscillating axle locks or controls are a design requirement, an interlock device must prevent boom movements until the oscillation is locked or controlled. •Also, if not designed for mobile use, an interlock device must prevent operation of the device until after the parking or holding brake has been set.
