Looking for high-quality trailer landing gear, trailer parts, or trailer rims? CIMC Equilink supplies reliable trailer landing gears—critical components for semi-trailers—used in new CIMC trailer builds and after-sales markets. These durable, accessible trailer parts support trailers when disconnected from tractors, ensuring stability and safety. Below’s a detailed guide to their structure, types, functions, and maintenance.  

Structure of Trailer Landing Gear

Trailer landing gear has a straightforward yet robust structure, consisting of core components including speed gear boxes, brackets, spring plates, torque rods, and crank handles. CIMC Equilink also provides all small supporting trailer parts for replacement and maintenance, ensuring full compatibility with our landing gears.  

Types of Trailer Landing Gear

There are two common types of trailer landing gear to meet different operational needs:  

1. Single Trailer Landing Gear: Features separate gear boxes and crank handles on both sides, requiring independent operation of each side to lift or lower the trailer.  

2. Dual Trailer Landing Gear: Equipped with one gear box and one crank handle on one side—operating the single crank handle lifts or lowers both sides simultaneously, improving efficiency.  

Our landing gears fit most semi-trailer models, including 17’ and 19’ configurations, delivering consistent performance for various transport scenarios.  

  

Functions of Trailer Landing Gear

As essential trailer parts, trailer landing gears serve a core purpose: supporting the static trailer body when disconnected from the tractor. A built-in spiral lifting mechanism adjusts the trailer’s height to adapt to different ground conditions.  

• When the tractor is connected or the trailer is in motion: The landing gear must be fully raised to avoid contact with the ground.  

• When disconnecting the tractor and securing the trailer: Use the crank handle to lower the landing gear, ensuring the trailer is stably supported on the ground.  

Maintenance Tips for Trailer Landing Gear

Trailer landing gears are high-consumption trailer parts, so quality and regular maintenance are critical. Poor-quality landing gears (often 10-20kg lighter than qualified products, made with inferior materials and thin steel plates) pose severe safety risks. Follow these maintenance steps to extend service life:  

• Regular Inspections: Check the landing gear before long trips—look for rust, loose components, or signs of wear.  

• Rust Prevention: Water easily seeps into the mechanism during travel, causing rust that hinders lifting/lowering. Keep the landing gear dry and clean.  

• Lubrication: Apply lubricant regularly to ensure smooth operation of the spiral lifting mechanism and gear box, preventing internal component damage.
