SEVE railway axles: advanced technology for optimal performance

Enhanced stability for maximum safety

Stability in rail equipment is key to ensuring top performance and minimizing accident risk. That’s why SEVE axles feature advanced technologies:

• Widened wheelbase, ensuring better load distribution and increased stability in all positions
• Balanced load descent, both laterally and longitudinally, minimizing tipping risk thanks to dual oscillating axles
• Lateral absorption up to 46 mm, compensating for track irregularities and improving guidance

A unique inverted suspension system means the axles require no hydraulic or electric locking cylinders, eliminating the need for locking/unlocking and the associated risk of tipping when translating with an offset load. The SEVE system works fully passively, ensuring safer operation.

These features allow SEVE-equipped machines to operate securely even on newly laid or severely damaged tracks.

Performance and adaptability with advanced hydrostatic drive

SEVE railway axles stand out with their smooth and efficient hydrostatic drive system. With a 115 cm³ variable-displacement motor, the machine can operate at two travel speeds: 0–15 km/h and 0–30 km/h. This flexibility allows operators to adjust speed based on task requirements, from delicate maneuvers to fast travel on rail lines.

In emergencies, a motor disengagement system allows quick towing, providing a reliable solution for breakdown or recovery operations.

Maximum safety with a high-performance braking system

Rail safety relies heavily on effective braking. SEVE axles include several complementary braking systems:

• Dynamic disc brakes, delivering quick response and excellent kinetic energy dissipation
• Hydrostatic braking, offering precise and powerful deceleration control
• Multi-disc dry static brake, ensuring safe locking when stationary or parked

These integrated systems ensure full control of the machine even in difficult conditions.

Load capacities and custom options for professional needs

SEVE railway axles are built to withstand heavy loads, providing unmatched robustness:

• Static capacity: 24 tonnes per axle – ideal for lifting and supporting heavy loads
• Dynamic capacity: up to 22 tonnes per axle – enabling smooth movement even under heavy load

Optional features include:

• Pedal-passing mode: Allows speeds up to 5 km/h over announcement pedal crossings
• Integrated axle coupling system: Enables connection of a self-propelled quasi-machine on tight curves (min. radius R = 80 m)

With these options, SEVE axles offer greater flexibility to meet the varied requirements of railway professionals.

A strategic choice for railway professionals

By integrating SEVE railway axles into their equipment, transport and maintenance operators benefit from:

• Smooth and precise traction, thanks to advanced hydrostatic drive
• Enhanced stability, improving control and offset load handling
• Optimized braking, ensuring safety for operators and machinery
• High load capacity, supporting demanding handling and transport operations
