The Alpha by Adr bring together the ruggedness and reliability expected of mechanical components in the agricultural sector with easy installation and minimal maintenance requirements
Traditionally, farmers and manufacturers have had to choose between mechanical or hydraulic suspensions with interconnected wheels, and hydraulic systems with independent wheels. For years, ADR has offered solutions to suit every agricultural trailer configuration, emphasizing the importance of selecting the right suspension system for each specific application.
At the latest Agritechnica trade fair, Adr introduced a game-changing suspension system that merges the best features of both traditional and modern setups. The new Alpha suspension combines the strength and durability of axle-based mechanical or interconnected hydraulic systems with the sensitivity and stability of fully independent hydraulic suspensions—without the mechanical complexity or functional drawbacks that can sometimes plague the latter.
Versatile, functional, and built to last
Designed with multi-purpose functionality and simplicity in mind, the Alpha suspension bridges two previously distinct engineering approaches. Built on a robust triangulated structure, it connects the axle to the trailer chassis via an elastic hinge, allowing for 12 degrees of lateral oscillation in either direction. This movement keeps wheels firmly in contact with the ground, even on highly uneven terrain.
A heavy-duty stabilizer bar prevents swaying or fishtailing, while two hydraulic cylinders control vertical wheel movement up to 250 mm. The chassis-side cylinder mounts are supplied as standard, making installation fast and straightforward.
Simplified Installation, Zero Lubrication, Maximum Adaptability
The entire suspension is bolt-mounted, meaning no welding is required. Wheel alignment can be optimized by rotating the stabilizer bar’s central body, and the axle-side mounts of the cylinders can be freely positioned to adapt to different trailer models, since they’re decoupled from the articulation joint.
These engineering choices lead to major user benefits:
- No periodic lubrication needed, as all bushings are self-lubricating
- Lightweight design helps reduce trailer tare weight
- Modular options for OEMs: order as a kit compatible with existing TeknoAx axles in stock, or pre-assembled for plug-and-play installation
With the Alpha series, ADR sets a new standard for agricultural trailer suspensions: durability meets innovation, all in a system that simplifies assembly and reduces long-term maintenance to a minimum.
