Support column (main frame): The primary vertical load-bearing structure, typically made of high-strength steel.
Height adjustment rack: A serrated bar on the column that allows for precise adjustment of the support height.
Safety pin: Inserted into the gap in the rack, it locks the height adjustment and serves as a key safety feature.
Support head (top pad): The top component that contacts the vehicle chassis, typically equipped with a rubber or polyurethane pad to prevent damage and increase friction.
Support base: The wide platform at the bottom increases the contact area with the ground, providing stability and preventing slippage.
