Product Introduction

Hydraulic landing legs are specialized support devices for semi-trailers. Constructed from welded high-strength alloy steel, they offer high load-bearing capacity and excellent resistance to deformation. Driven by a hydraulic system, they provide effortless lifting and smooth operation, significantly reducing the need for manual labor compared to traditional manual landing legs.
During cargo loading/unloading or stationary maintenance, the legs extend to support the trailer, stabilizing the vehicle body, relieving stress on the axles and suspension, and preventing the trailer from tipping over after the tractor unit is detached. Featuring reliable, leak-resistant seals, they are suitable for demanding operating environments such as construction sites and long-haul transport. Options include single-acting or synchronized systems; they are compatible with various trailer types, support custom specifications, and are easy to install and maintain.
Product Types
1. By actuation method: Hydraulically linked outriggers and hydraulically independent outriggers. Linked versions allow for synchronized lifting/lowering on both sides; independent versions allow for separate control of each side, accommodating uneven ground.
2. By installation style: External and internal. External types offer easy removal and maintenance, while internal types save space.
3. By load capacity: Light-duty, medium-duty, and heavy-duty, catering to the load requirements of various semi-trailers.
4. By configuration: Electro-hydraulic models and pure hydraulic models (with manual pump).

Features and Advantages
1. High load-bearing capacity: Made of high-strength alloy steel, it is resistant to heavy pressure and deformation, suitable for heavy-duty semi-trailers, and provides stable and reliable parking support.
2. Effortless and efficient lifting: Hydraulic drive, electric/manual pump optional, no manual hand cranking required, smooth lifting, adaptable to uneven ground.
3. Excellent sealing performance: High-quality oil-resistant seals effectively reduce oil leakage, prevent dust and mud, and adapt to complex and harsh working conditions on construction sites and outdoors.
4. Durable: The entire structure is welded and the surface is treated with anti-rust paint, making it corrosion-resistant, wear-resistant, and long-lasting.
5. Easy installation and maintenance: The structure is reasonably designed, easy to disassemble and repair, supports single-action and linkage options, and can be adapted to various trailer models.
6. Protective function: When loading and unloading cargo, the trailer shares the weight of the vehicle, effectively protecting the axles and suspension components and preventing the trailer from overturning.
