Not every tree removal is simple and straightforward. There are some situations that are more challenging, which means that tree removal should be left to the professionals. 

1. Extreme Height 

A tall tree requires special equipment and skills to remove safely. The trick is to remove the tree in pieces. First, all the limbs are cut off and removed working from the ground up. Then climbers are sent up that will section the trunk, working from the top down. Each section is lowered to the ground as it is removed, using a crane.

2. Nearby Structures

Removal is particularly tricky when the tree is growing up against a building or other structure. Branches must be trimmed carefully so no branches will break a window or damage the siding during removal. Rigging may also be used to ensure that no section of the trunk falls toward the structure, as the rigging will stabilize the trunk section so it doesn't fall in an unexpected manner.

3. Access Issues

Tight spaces, such as in a narrow side yard, can pose access issues for equipment and workers. It can be even more difficult if the area can't be reached by the equipment due to blocked access. Fortunately, removal is still possible with a grappling crane, which is a remote-controlled crane that uses a grapple-style cutting tool to remove and simultaneously lift out the tree piece by piece. 

4. Tree Entanglements

Removing a fallen tree that has landed on another tree or shrub requires care. Entanglements with nearby trees and shrubs can make the removal difficult, especially when the goal is to save the other trees. A turning hook may be used to help roll the tree off of the one it is entangled with, as this is safer and less likely to damage the tree that you wish to save. Once the main entanglement is freed, the tree can be limbed and sectioned for removal.

5. Overhead Lines

Trees that grow into overhead lines, particularly power lines, pose a special hazard due to electrocution and fire risk. A professional tree service will notify necessary utility companies and then take steps to ensure safety for everyone around. They may need to take extra steps to close off public access to the area, and special equipment may be used to ensure safety and prevent branches from pulling down the lines during removal. Otherwise, the process is little more than limbing and then sectioning the trunk.
