We know that there are many landing gear products on the market to choose from, and it can be overwhelming to find the one that fits the specs of your trailer. One important deciding factor is how much weight your semi-trailer landing gear can hold. We’re here to break it down for you.


What Is the Purpose of Semi-Trailer Landing Gear?


Trailer landing gear is the retractable support equipment that keeps a trailer level when removed from the semi-tractor. It’s located at the front of the trailer and will keep you and your truck safe. The landing gear consists of two legs that can support the heavy weight of the trailer.

What Are the Different Types of Semi-Trailer Landing Gear?


Here at JOST International, we’re an industry-leading manufacturer of trailer landing gear and component parts. We offer an expansive product line, and our signature internal gearbox is the key feature and integral part of our landing gears’ durability and . Our internal gearboxes protect the gears from damage and significantly reduce moisture intrusion, which extends the product’s life and provides our customers with a stronger, more reliable product.

While there are several types of semi-trailers landing gear, most can be divided into either drop legs or standard landing gear legs. Here’s what you need to know about both. 


Drop Legs


Drop leg landing gear products utilize a spring-loaded lower tube. The drop handle must be turned 90 degrees to disengage. The internal spring keeps the drop leg retracted until the force is applied. A smaller spring on the drop handle forces it inward, allowing the drop handle to align with the following hole location as the internal spring retracts the lower tube.

Drop legs are ideal for various commercial trucking applications looking to save operator time and overhead costs. They’re lightweight, easy to use, and perfect for smaller loads and drivers looking for an efficient way to speed up the coupling and uncoupling process.

Landing Gear Legs


Our landing gear maintains all the mechanical advantages of JOST’s drop legs, but trades the spring drop function for a more durable,single speed and two speed crank mechanic only. JOST internal gearboxes are completely filled with premium all-weather lubricant, an elevating screw that can be fully encased in a grease tube, completely sealed landing gear legs, and austempered ductile iron gears.

JOST landing gear is ideal for heavy-duty applications. They’re the best option for protecting against water and chemicals on roads.
