Under what circumstance can hooks be used without latches?

Hooks can be used without latches specifically when the application makes use of the latch impractical or unsafe. This is recognized in the industry because there are certain scenarios where using a latch could actually create a hazard rather than prevent one. For example, in situations where the hook is being used in a manner that may cause the latch to obstruct the load or interfere with the lifting process, it may be safer to operate without a latch. This does not negate the need for safety, rather it emphasizes that safety practices can vary depending on the context and nature of the lifting operation.

In other cases, such as a broken latch, it is essential to repair or replace the latch before proceeding. Additionally, using hooks without latches under lightweight load conditions does not justify their removal because safety standards typically apply regardless of load weight. Finally, if the application does not require a latch, it still does not justify the absence of one unless specific safety evaluations determine that it is practical to operate without it. Hence, safety protocols are always prioritized in crane operations.
