Product Type
The external landing gear is a critical support component for semi-trailers, widely used in drop-and-hook transport operations and mounted on both sides of the trailer. Constructed from high-strength alloy steel through welding and forging, the unit features a robust structure capable of withstanding heavy loads and impacts. It is equipped with a manual drive mechanism supporting both independent and synchronized operation modes, ensuring convenient and effortless height adjustment.
The product has undergone rigorous flaw detection and load testing to ensure stable load-bearing performance. It reliably supports the trailer's weight during parking, loading/unloading, and tractor detachment, thereby reducing stress on the kingpin and ensuring operational safety. Suitable for various semi-trailer types-including flatbed, stake-side, and box trailers-the landing gear can be customized regarding load capacity and mounting dimensions to meet specific customer requirements. Each unit undergoes strict factory quality inspections, offering a long service life and easy maintenance.
Product Types
1. Independent-action landing legs: The left and right legs are controlled separately via hand cranks, allowing for individual height
adjustment. Suitable for uneven terrain requiring leveling, they are easy to maintain and represent a common market standard.
2. Linked-action landing legs: A single crank simultaneously operates the lifting and lowering of both legs, saving time and effort. Ideal for flat surfaces and freight trailers that frequently undergo coupling and uncoupling operations.
3. Heavy-duty landing legs: Feature thickened housings and large-module gears for high load-bearing capacity; suitable for oversized cargo transport and heavy-duty semi-trailers.
4. Lightweight landing legs: Feature a lightweight structure and reduced dead weight; primarily used for standard-load box trailers, stake trailers, and general freight trailers.
