THE END OF HYDRAULIC GROUND WHEELS?


HOW AEROMOB REDEFINED RELIABILITY IN HELICOPTER GROUND OPERATIONS


The replacement of hydraulic systems with a fully mechanical design — including, in the HARDMOB line, a patented force-multiplying mechanism that also eliminates traditional lever systems — marks a structural shift in helicopter ground handling, with direct implications for safety, availability, and operational efficiency.

EROMOB’s rise as the world’s most reliable helicopter ground wheel manufacturer in 2026 signals a clear turning point in a segment long dominated by hydraulic systems prone to leaks, failures, and operational downtime.


In recent years, the Brazilian company has expanded its footprint among civil and military operators across five continents. This growth reflects a broader shift in how ground operations are evaluated: reliability, simplicity, and ergonomics are no longer secondary considerations — they are operational requirements.


The increasing adoption of HELIMOB and HARDMOB wheels by armed forces and helicopter manufacturers did not occur overnight. It reflects a consistent trend across diverse operating environments — from offshore operations to high-tempo military bases — where ground handling has become a critical factor in both safety and aircraft availability, particularly for skid-equipped helicopters.


32 May/June 2026 MOVING AWAY FROM HYDRAULICS


For decades, hydraulic systems remained the standard despite well-documented limitations. Operators routinely dealt with oil leaks, inconsistent lifting performance, excessive weight, and imprecise fittings. In many cases, wheels failed to lift the aircraft sufficiently, resulting in skid drag during movement and long-term wear.


In high-utilization environments, these limitations translated into measurable operational inefficiencies: delays, increased maintenance, and unnecessary exposure to risk.


AEROMOB took a different approach. Rather than refining hydraulic systems, the company eliminated them entirely.


Its fully mechanical design, built in chromoly steel and manufactured to tighter tolerances than typically seen in GSE equipment, removes key failure points. Without seals, hydraulic fluid, or pressure chambers, the system delivers consistent performance over thousands of cycles, even under harsh operating conditions.


With the HARDMOB line, AEROMOB advanced further. The concept replaces traditional lever-based mechanisms with a patented force-multiplying system developed in-house. The result is lower operator effort, greater movement predictability, and the elimination of variables associated with manual actuation — establishing a new efficiency benchmark in helicopter ground handling.
