2023年7月28日 · Safe Working Load (SWL), sometimes also referred to as Normal Working Load (NWL), is the maximum force or load that a piece of lifting equipment, such as a crane, winch, hoist, or an accessory, can safely handle without the risk of failure or breaking.

WLL and SWL are abbreviatons for Working Load Limit (WLL) and Safe Working Load (SWL). The main difference between the two terms is that SWL is the older term. Today, SWL isn’t used anymore because the term is completely replaced with WLL and MRC.

2024年9月2日 · 1. SWL（Safe Working Load）指的是安全工作负载，这是指在卸扣上使用时，确保索具安全使用的最大载荷限制。 2. WLL（Working Load Limit）指的是工作负载限制，其含义与SWL相近，都是用来指导卸扣上可以安全施加的最大载荷。

SWL 是针对载重或起重等有 荷载力矩 的装备定义的范围概念，如题主所说，一般是针对起重机、 重型运输车辆 等特种装备。 而如果您要标注的是货物本身，又哪来的SWL呢？ 此时的标注应该时针对货物的质量及重心位置，对于一个静态的物体或者设备而言，它的质量是既定的，有哪来最大负载与最小负载的差异？ 比如我有一个设备，需要做起重吊装拉力测试并标注SWL，试验中最大负载最小负载怎么确定？ 标示的应该是额…

2025年1月7日 · Safe Working Load (SWL) Definition: The Safe Working Load is the maximum load that a piece of equipment, such as a rope, chain, or lifting sling, can handle safely under normal operating conditions without risking failure. Key Features: Safety Factor: SWL is calculated by dividing the Breaking Strength by a safety factor (SF).

The terms working load limit (WLL) and safe working load (SWL) both refer to the maximum weight that a given piece of equipment can safely lift. For example, if a chain hoist has a WLL or SWL of 500kg, it should not be used to lift loads that weigh more than 500kg.

2014年2月13日 · WLL and SWL are abbreviated terms commonly used in the field of engineering. “WLL” stands for “working load limit” while “SWL” stands for “safe working load.” The main differences between safe working load from working load limit is that “SWL” is the older term.

2024年9月18日 · Two commonly used terms are working load limit (WLL) and safe working load (SWL). However, while both SWL and WLL may be used interchangeably, there are some key differences to note. Here is an overview to explain the differences between a safe working load and a working load limit from the lifting experts here at Metreel .
