Applications of Custom Flexible Drive Shafts in Road Construction
Machinery
Where Flexible Drive Shafts Make a Difference
Phidix’s custom flexible drive shafts are engineered to deliver
precise mechanical control in equipment operating under demanding
conditions—especially within road construction and heavy machinery
environments.
Their design offers high routing flexibility, resistance to harsh
elements, and accurate force transmission, making them ideal for
machinery with limited space and high vibration.
Primary Equipment Applications
1. Vibratory Rollers
Used to control:
• Screed vibration systems
• Hydraulic valve actuation
• Emergency engine stop cables
Requires flexible routing with stable push-pull response under high
vibration
2. Asphalt Pavers
Used to:
• Adjust feed auger controls
• Trigger material gate opening/closing
• Operate throttle linkage or directional change
Needs durability in high-heat, dust-laden conditions
3. Road Milling Machines
Used to:
• Engage cutting drum movement
• Control hydraulic height adjustment
• Link engine stop/start mechanisms
Prioritizes minimal backlash and consistent mechanical response
4. Wheel Loaders
Used to:
• Control bucket tilt and lift
• Operate transmission gearshift
• Interface with brake or clutch control
Requires minimal bending radius and corrosion resistance
5. Excavators & Earthmovers
Used to:
• Transmit motion to boom/bucket functions
• Link cab controls to remote valves
• Integrate safety lock overrides
Typically configured with customized stroke length and conduit
type.
Why Flexible Shafts Over Rigid Linkages?
| Flexible Shaft Advantage | Rigid Linkage Limitation |
| Small bend radius (as low as 40mm) | Needs straight mounting path |
| Withstands vibration, dirt, heat | Susceptible to looseness/failure |
| Easy installation around obstructions | Complex layout, higher labor |
| Custom length & stroke options | Limited adjustability |
Commonly Used Models for These Applications
| Model | Ideal Use Case |
| SUVL-BSP-TT-100-2035 | Standard routing, moderate force |
| SUL-TG-150-3780 | High-force transmission in tight routing |
| SU-VL-TT-70-1200 | Compact machinery with lightweight control needs |
