绞车等级

[中文适用范围]： 本 SAE 标准仅适用于主要为间歇性牵引和提升而设计的新型绞车，其配置和状况与制造商发货时相同。它们不得以任何方式用于人员流动。它们可以由制造商推荐的任何电源驱动，并且能够在任一方向供电。它们将配备自动安全制动系统，以在动力下降时控制负载，并在未向绞车输送动力时积极保持负载。液压流量控制阀或类似装置可以用在制动系统中以在动力下下降时控制负载。用于释放滚筒以实现“自由卷绕”的离合器可以提供并且将被设计成在负载下不会脱离自身。可以提供拖曳制动器来控制“自由绕线@”但不能用来控制或保持负载。动力源@例如液压马达@即使它们可能由绞车制造商提供或推荐@就本文件而言@不被视为绞车的一部分@除非它们是制动系统的一部分。 [外文原描述]： This SAE Standard applies only to new winches which are primarily designed for intermittent pulls and lifts and whose configuration and condition are the same as when they were shipped by the manufacturer. They are not intended to be used in any manner for the movement of personnel. They may be driven by any power source recommended by the manufacturer and will be capable of being powered in either direction. They will be equipped with an automatic safety brake system to control a load when lowering under power and positively hold a load when power is not being delivered to the winch. A hydraulic flow control valve or similar device may be used in the brake system to control a load when lowering under power. A clutch to release the drum for “free-spooling” may be provided and will be designed not to disengage itself under load. A drag brake may be provided to control “free-spooling,” but will not be relied on to control or hold a load. Power sources, such as hydraulic motors, even though they may be supplied or recommended by the winch manufacturer, are not considered a part of the winch so far as this document is concerned, except to whatever extent they are a part of the brake system.Cross Reference:
