Cargo Handling & Stowage | Cargo Crane

Summary

This video provides an in-depth exploration of cargo cranes, detailing their essential components, operational mechanisms, and critical safety protocols. Viewers will learn about the crane's structure, including the crane post, body, and driver's cabin, as well as control functions for efficient cargo handling. The importance of adhering to safety guidelines, such as respecting safe working loads and understanding emergency procedures, is emphasized to prevent accidents and ensure smooth operations. This informative guide is ideal for those looking to enhance their knowledge of crane operations in industrial settings.

Takeaways

• 🚧 A cargo crane consists of several key components, including a crane post, electric switchboard, ladders, and a driver's cabin for operation.
• 🔄 The crane body can rotate 360 degrees, allowing for flexible cargo handling and positioning.
• 📏 The boom angle indicator shows the angle of the boom, which directly affects the lifting capacity of the crane.
• 🔒 Safety clips are crucial for preventing rigging from slipping off the crane hook during operation.
• ⚠️ Never exceed the safe working load rating of the crane, which is clearly marked on its structure.
• 🔌 It is important to know how to switch off the crane in case of an emergency.
• 📦 All rigging and associated gear should be clearly identified and certified for safe use.
• 🛠️ Two cranes can be rigged together for twin operations, but both must maintain the same boom angle before changing over.
• ⚙️ Rigging is as important as the crane itself; ensure that straps and strops are suitable for their specific loads.
• 🔧 Always secure the crane when operations are complete and never leave it running unattended.

Q & A

What are the main components of a cargo crane?

A cargo crane consists of a crane post, electric switchboard valves, a ladder, a crane body, cargo winch, topping span winch, a driver's cabin, and various sheaves.

What is the function of the driver's cabin in a cargo crane?

The driver's cabin houses the crane controls and has a glass front to provide a clear view for the operator.

How does the crane body contribute to its functionality?

The crane body can rotate 360 degrees, allowing for versatile movement and positioning during cargo handling.

What safety features are associated with crane operation?

Important safety features include safety clips to prevent rigging from slipping off hooks, a boom angle indicator to determine lifting capacity, and limitations on safe working loads.

What should an operator do in case of an emergency?

The operator should know how to switch off the crane in an emergency and locate the nearest spill gear for containing any leaks from the hydraulic system.

What are the critical safety precautions to observe while operating a crane?

Operators should never exceed the safe working load, secure the crane when operation is complete, and not leave the crane running unattended.

What is the importance of rigging attached to a crane?

Rigging is crucial for safe crane operation; it must be clearly identified for specific use, and all associated gear should have certificates preserved throughout its use.

Can two cranes be used together, and if so, what must be ensured?

Yes, two cranes can be rigged together for twin operations using a ram's horn hook, but the boom of both cranes should be at the same angle before changing over to twin operation.

What limitations should an operator know regarding crane use?

An operator should understand the limitations of the crane, its limit switches, and ensure not to use cranes for dragging weights.

How does the boom angle affect lifting capacity?

The boom angle determines lifting capacity; a lower angle results in lesser lifting capacity, while a higher angle increases it.
