The landing legs of a heavy-duty semi-trailer are crucial components used to support the weight of the trailer. Their main functions are as follows:

• Weight Support: When the semi-trailer is separated from the tractor, the landing legs extend to the ground, supporting the weight of the front of the trailer. This prevents the trailer from tilting or tipping over due to the loss of support from the tractor, ensuring stability when unhitched and facilitating loading/unloading of goods and the connection/disconnection of the trailer and tractor.

• Height Adjustment: Landing legs can usually be adjusted in height manually or electrically to accommodate uneven ground, ensuring the trailer body remains level after separation for subsequent operations (such as connecting to a tractor or loading/unloading goods).

• Enhanced Stability: Compared to standard landing legs, heavy-duty landing legs have higher structural strength and load-bearing capacity to meet the high weight requirements of heavy-duty semi-trailers. In complex road conditions or heavy-load situations, this reduces the risk of leg deformation or damage, improving overall stability.

They are an indispensable part of the daily operation and maintenance of semi-trailers, directly affecting operational safety and efficiency.
