Landing gear Modul
The Modul series of landing gear is extremely versatile. Thanks to its modular construction with variable mounting and operating heights, various crank handles and connection shaft lengths and different foot types, all client requirements can be met.
OPTIMA is the weight-optimized landing gear for longdistance transport applications. The Modul B is the proven best-in-class landing gear that can be compiled individually according to customer requirements and offers very versatile use. The Modul C range consists of various landing gears which are designed for special applications.
All ranges offer convincing product advantages: the integrated gearbox has optimum protection, and requires minimum force to be applied on the crank handle in both directions. At the same time, Modul offers an extraordinary increase in lift of up to 120 mm combined with smaller dimensions for fitting. It goes without saying that the landing gear is extremely sturdy and complies with the strict AAR standard.
The landing gear is not a standalone, functional device. It is designed to be mounted on a trailer. The vehicle may not be operated until it has been ensured that the towed vehicle with the support complies with the applicable national road traffic regulations. In Germany, the relevant “TÜV” Safety Regulations and “StVZO” Motor Vehicle Safety Standards are to be observed. The telescopic landing gear is always to be used in conjunction with the instructions for use issued by the manufacturer of the relevant trailer.
