Tree Saw Attachments for Excavators

 

GreenTec presents the world's largest saw with working widths of either 4.0 or 4.8 m (13’1” or 15’9”). It goes without saying that the capacity is huge.

 

All branches receive a smooth and even cut by the eight circular blades with carbide tipped teeth. It is a great solution for trimming back trees and hedgerows in agricultural areas or maintaining large forest territories.

 

The saw can be mounted on large backhoe loaders and excavators. We also offer smaller tree saws for skid steers, front loaders, telehandlers, mini diggers and boom arms.

Cavitation and anti-cavitation:

 

This product comes with an anti-cavitation valve which is used to minimize the risk of cavitation damage in connection with insufficient inlet pressure.

 

 

What is cavitation damage?

 

Cavitation occurs when the pressure drops below the vapor pressure, which will bring the fluid to boil as the boiling point is reduced. Liquid is converted to gas and then the temperature drops and the gas is converted back into compressed liquid again. If the pressure cannot be adjusted continuously, the above process wherein the liquid is converted to gas and back again will be repeated. In the process where gas is converted back into compressed fluid, small implosions that form heat and noise strong enough to erode metal will occur.
