锚缆释放钩（Anchor Line Trip Hooks）主要为船舶行业设计，在海上铺管及施工驳船周边的起锚或抛锚作业中实用性极强。起锚时，需使用高强度挂钩钩住锚浮标缆的绳环或绳眼，以便将其卷绕至工作船的卷筒上；抛锚时，工作船行驶至与驳船相距预设距离的位置，在锚脱离海底后，工作船开始释放绞车缆。当锚钩移动至距船尾约一半距离时，将牵制缆的小挂钩插入锚缆释放钩的底部孔洞中；进一步放松绞车缆时，牵制缆会收紧，促使锚缆释放钩自动脱离浮标缆的绳环，完成释放动作。
Anchor Line Trip Hooks were primarily designed for the marine industry. They are most useful in retrieving or setting anchors around marine pipe-laying and construction barges. When retrieving, an extra strong hook is necessary to snag the loop or eye of the anchor buoy cable for it to be wound on the drum of a work boat. When setting anchors, the work boat reaches the desired distance for the barge, and with anchor off of the ocean floor, the work boat begins to release the winch line. When the anchor hook reaches approximately half-way from the stern of the boat, the small hook of the hold back line is inserted into the bottom hole of the anchor line hook. When slackening the winch line further, the hold back line will tighten, causing the anchor line hook to trip or release automatically from the loop of the buoy cable.
