With fixed undercarriage
Thanks to the wide range of available configurations, fixed-width undercarriages are among the most versatile solutions and can be adapted to numerous applications.
With crossmembers
Fixed undercarriages with crossmembers provide an excellent base for applications requiring stability and simple integration into the machine structure.
Details
The use of crossmembers ensures simple and stable fastening to the machine frame, optimising assembly times.
Optional
We offer a wide selection of components, including standard or custom-designed crossmembers to perfectly match application requirements.
Applications
They are ideal for compact machines requiring stability and fast installation, such as crushers or recycling equipment.
With X-frame
Fixed undercarriages with an X-frame configuration provide the perfect balance between lightness and torsional rigidity.
Details
They are an excellent solution for evenly distributing operating loads, thanks to the use of a rotary joint, making them ideal for machines equipped with a slewing turret
Optional
We offer specialised technical support to analyse the application context and develop design solutions aligned with the customer’s operational and environmental requirements.
Applications
They are perfect for excavators or other applications needing reliable support for a slewing turret, complete with hydraulic system and dedicated accessories.
With H-frame
Fixed undercarriages with an H-frame configuration are ideal for applications that require structural strength and a high degree of operational flexibility.
Details
The H-frame, combined with a slewing joint and its hydraulic system, represents the ideal solution for machines that require stability and compactness.
Optional
We analyse each application and propose the most effective design configurations, developed around real operational requirements.
Applications
They are often used in applications that demand a stable base and simplified transport, such as earthmoving machinery.
With H-frame and removable side frames
The H-frame configuration with removable side frames is used in applications that need to optimise the machine’s transport dimensions.
Details
Removable side frames simplify logistics without compromising undercarriage performance, offering stability and robustness alongside the practicality of a separable structure.
Optional
We work closely with clients to develop the most suitable modular solution for each application, with particular attention to ease of transport and operational functionality.
Applications
Removable side frames are particularly well suited to applications with complex logistical requirements arising from size and weight restrictions.
Applications
Ustec undercarriages form the base of numerous applications, including demolition, drilling, recycling, forestry and more. Discover the solution best suited to your industry.
