Holland Atlas 55 Landing Gear

The HOLLAND Atlas 55 landing gear merges proven engineering technology with quality and durability to create a new standard in landing gear performance. From the smooth shifting and reliability of the patented Constant Mesh gearbox design, to the durability and toughness of the exclusive FloatingNut with Twin Bulkhead construction; the Atlas 55 offers a landing gear that was built to carry on the HOLLAND name and tradition of trouble-free performance and exceptional value for years to come.

Rugged durability and easy operation, including:
• constant mesh gearbox design for trouble-free shifting
• exceeds all AAR M-931 and all TTMA RP-4 performance specifications
• high-strength ductile iron gears
• standard 5-year and optional 10-year performance guarantee available
• reduced weight with increased structural integrity.
Eliminates high-to-low shifting problems common to traditional landing gear. Using a crankshaft with a roll pin, only the crankshaft moves to engage drive gears. No in-or-out movement of drive gears is required; keeping the gears constantly meshed. This design not only provides smooth shifting under loaded conditions, but also prevents slip cranking and difficult high-to-low shifting in cold weather.
The FloatingNut protects the elevating screw and threads from excessive side loading caused by dock-walk; damage which can cause poor cranking performance or binding. Unique twin-bulkheads, above and below the FloatingNut, further increase structural resistance to side-load forces when landing legs are fully extended.
