Landing gear

Landing gear are the front extending legs (usually two, one per side) of a fifth wheel or gooseneck trailer that support the front of the trailer once it is uncoupled from the tow vehicle. They raise and lower by an electric motor or a manual crank through a gearbox. Per-pair capacity is 6,000–10,000 lb (2,700–4,500 kg).

Travel is typically 18–24″ (45–60 cm), enough to raise or lower the kingpin onto pickups of different heights. Electric systems (Lippert, BAL Accu-Slide) include auto-leveling and an emergency manual override. Place plywood pads under the feet before uncoupling — otherwise either the asphalt sags or the legs themselves are damaged. Motor failures are common and should be tested in manual mode.
