Landing gear Modul

The Modul series of telescopic landing gear is extremely versatile. Thanks to its modular construction with variable mounting and operating heights, various crank handles and connection shaft lengths, plus five different foot types, all client requirements can be met.

Modul B is the optimised standard telescopic landing gear. The Modul C range consists of various landing gears which are designed for special applications.

Both 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 telescopic 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.

Tried-and-tested Modul system

Since the market entrance Modul landing gears are setting benchmarks. The modular construction allows a multitude of different varieties.

Telescopic landing gears

Modul B – Standard

  • Tried-and-tested standard telescopic landing gear
  • The modular construction allows universal application

Aluminium landing gear Modul CA

  • Weight-optimised
  • Premium telescopic landing gears in aluminium design
  • Greatest possible weight advantage for telescopic landing gears
  • Ideally suited for tank and silo vehicles

Special telescopic landing gears Modul C

  • Modul C special telescopic landing gears for special applications
