Fixed track gauge can be realized in different configurations:
- with cross beam
- with central frame to X frames ( for excavator)
Fixed track frames are suitable for many different types of applications (crushers, excavators, Small Drilling)
Undercarriages with X typically used in excavators are ideal for all machines that need a rotating turret and constitute the best compromise between lightness and torsional rigidity of the metal structure.
Undercarriages with central frame can be designed complete the hydraulic coupling and its rotating system, swing gear and other accessories.
Are used machines that require security and stability in working phase and transportability. Below the main types
