The grab does not open. Actions of an ETO on a ship. Specifics of working with GBM, TOBU, SMAG grabs

Greetings! In the previous article on cargo cranes, we considered general issues of crane operation and repair for a ship's electrician. The topic of grabs was also touched upon with a link to a separate article.

Therefore, in this article we will "deal" with grabs and their frequent breakdowns. First, let's consider grabs with radio control. These grabs open from a remote control, which is operated by the crane operator or a worker on deck.

This article has been hanging in my drafts for about three years, I just couldn't finish it. I gathered my strength and actually ask you to read it. Especially relevant for beginners!

Troubleshooting Electrical Diagrams: A Practical Approach

Understanding and troubleshooting electrical diagrams is essential for diagnosing faults in electrical and electronic systems. Here’s a step-by-step approach:

1. Understand the Diagram Types

• Wiring Diagram – Shows physical connections and wire paths.
• Schematic Diagram – Represents components symbolically, focusing on functionality.
• Block Diagram – Provides an overview of system operation, showing major components.
• Single-Line Diagram – Used in power distribution to show major connections with simplified lines.

How to read electrical diagrams on a ship? Main engine turning gear operation diagram

Greetings! You have motivated me to write this article. Thank you for your comments to the previous article "Installing a timer in the electrical diagram of the main engine turning gear" and in social network groups. In fact, writing such articles takes a lot of time and effort, so motivation and support are needed. And it is enough to just write a positive review ;)

In this article I will try to explain in simple language the principle of reading electrical circuits on a ship using the example of the main engine turning gear device.

Phase fail. The turning gear and the LO autofilter of the main engine do not start

Greetings! Today we have a problem with the turning gear and the LO autofilter of the main engine. During the preparation of the main engine, alarms were sent to the alarm monitoring system in the ECR indicating that some kind of problem had occurred with these mechanisms.

It is necessary to pay attention to the fact that problems with starters or motors occurred at the same time and perhaps they have something in common. On a ship, these systems are not connected to each other in any way.
