Your project can run smoothly with the right equipment. When choosing your machinery, consider these factors:

1. Working height: Find out the maximum height of the site you are demolishing. This measurement will help you determine if you need high-reaching equipment.
2. Ground conditions: Before you start working, check the ground conditions with an engineer. The ground’s weight capacity and security will impact which equipment is safe to use on-site.
3. Attachments: Research which attachments will work for your project and ensure you have them readily available.
4. Size: Always make sure you can safely use the attachment within a safe working distance. If you have to extend a crane or excavator’s arm fully, you might need to get a larger version.
When you pay attention to those aspects, you can narrow your search for the right tool.
