Jost Modul Landing Legs

Landing Legs Flat Feet

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 catered for.

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

Both ranges offer practical 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 support 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.

  • Easy to assemble and replace foot system
  • Greatest flexibility of installation thanks to a range of back plates and only a slight overhang above the connection shaft
  • Various crank handles and connection shaft lengths
  • Significant gain in lifting force compared to comparable products
  • Attractive design
  • For universal application
  • Type reduction thanks to modular system guarantees high level of flexibility in spare parts business

Patented Modul drive

The patented drive is perfectly protected by the internal construction. In addition it offers various advantages in daily use.:

  • Easy to change between high and low gears
  • Very compact construction with high efficiency and extremely low wear
  • Large lifting force per turn of the crank with low crank force allows easy and convenient operation
  • Reliably secured against run-down

FAQs

What is the travel of the JOST MODUL B landing legs?

The MODUL B has a nominal travel of 520 mm (leg movement from fully retracted to fully extended).

How much lift can the legs provide at the trailer?

With the feet set to 300 mm ground clearance when fully retracted, there is approximately 220 mm of usable lift after the feet contact the ground (520 mm travel − 300 mm clearance = 220 mm). Actual lift can vary with suspension deflection, tyre squash and load.

What is the ground clearance with the legs fully retracted?

We typically set the bottom of the feet to ≈ 300 mm above ground when raised. This can be adjusted at build to suit fleet policy or site requirements.

Are landing legs intended for jacking or height correction at docks?

Landing legs are for supporting the trailer and making modest height corrections. They are not a substitute for a workshop jack. Always follow your operator procedures (chocking, surface checks, load condition) when using the legs to fine-tune height at a bay.

How do I check the MODUL B lift is sufficient for my site?

Measure the trailer kingpin height vs. your dock or yard variance. If the variance is ≤ the effective lift (~220 mm with a 300 mm foot clearance), the legs will typically cover the difference; otherwise consider site or spec changes (e.g., foot setting, suspension raise/lower).
