Heavy Finger Grapple, also known as the Australian-style grab hook, is a type of special excavator attachment typically used in specific work scenarios. According to the search results, excavators can be classified into different categories based on tonnage and requirements, including ultra-large excavators, large excavators, medium excavators, small excavators, and mini excavators. Each type of excavator is suitable for different working environments and load requirements.

For the Australian grab, it is usually suitable for the following work scenarios:

When it comes to the tonnage requirements of the excavator, it is usually necessary to choose the appropriate model of excavator based on the specific workload.

- Workload: Choose the appropriate excavator tonnage based on the weight of the items that need to be moved.

- Working Environment: Consider the size of the working space and terrain conditions, and choose an excavator with suitable size and mobility.

- Versatility: If you need to perform a variety of different tasks, it may be more appropriate to choose an excavator that can quickly change attachments.

Specific to the use of the Australian grab, an excavator should be selected that can carry the weight of the grab and provide sufficient power for grabbing and handling operations. The tonnage of the excavator should match the design and work requirements of the grab to ensure the safety and efficiency of the operation. The search results provided different models of excavators and their characteristics, which can be used to select an excavator suitable for specific tonnage and work requirements.
