BKT Airomax AM-27 — not just a tire for a mobile crane, but a high-speed mobility system for heavy machinery. Designed for machines for which the road is not a workplace, but a path to the object, it eliminates the classic compromise between off-road capability and high-speed highway characteristics. The model allows the crane to move between objects at almost cargo speed, without compromising readiness for immediate work on soft ground.
Dual Mode Operation
A two-mode directional tread pattern with zonal optimization is the basis of the tread. The central zone with a staggered (overlapping) arrangement of elongated blocks forms a stabilizing track. When moving on asphalt, these blocks create a continuous contact line, reducing rolling resistance, vibration, and noise. The outer rows of blocks with sharp, beveled edges act as active ground grippers. Their geometry is designed for effective "biting" into the ground base with simultaneous self-cleaning — large voids between the blocks actively expel dirt and prevent clogging.
Protection Against Deformation Under Critical Load
The uniqueness of the tire lies in the reinforced carcass with a multi-layer structure of textiles and stabilizing elements. This design is specifically designed to counteract the enormous deforming forces that occur when the crane is working on outriggers or moving with a partial load over uneven terrain. The reinforcement prevents irreversible deformation of the sidewalls and radial breaks, maintaining the geometry and integrity of the tire even after intense static and dynamic loads.
Thermal Stability and Durability
A specialized heat-resistant compound has been developed for the model, which includes polymers with high heat dissipation and reinforcing fibers. Its main task is active heat dissipation and protection against mechanical stress, which is the main factor in preventing delamination and cracking. At the same time, the mixture has high resistance to abrasive wear from sand and gravel, crack resistance, and multiple impact loads, ensuring the integrity of the tread on the construction site.
Key Features of BKT Airomax AM-27:
- a tread with dual functionality — central zone for high-speed, economical, and "cold" movement on hard surfaces + aggressive shoulder blocks for instant traction on the construction site;
- a multi-layer reinforced structure for protection against destructive loads during crane operation and transitions over rough terrain;
- a special formula for efficient heat dissipation and protection against delamination during transportation, as well as wear;
- deep voids in the shoulder area for forced removal of soil and maintenance of passability.
