How to Deal with Pit Protection Failure in Lift Vehicles?
2 Answers
Most fixed hydraulic lifts use overflow valves to prevent overloading, as overflow valves make it relatively easy to achieve the function of preventing overloading. To prevent the lift from harming people and equipment, most fixed lifts are equipped with leakage protectors, and protective grounding measures must be implemented.
When dealing with lift car pit protection failures, I believe safety is the top priority. These failures are usually caused by sensors being covered in dust or oil, leading the system to falsely report the presence or absence of a pit. I first stop the machine, unplug the power supply to ensure the operation area is safe, then use a soft cloth to clean the sensor surface and check for obvious dirt. If the issue persists, I try restarting the control panel—sometimes minor software glitches are resolved this way. However, for hardware issues like broken wires or damaged mechanical parts, I cannot fix them myself; I recommend immediately contacting a professional team for inspection and repair, as they have specialized tools and expertise. Regular maintenance, such as cleaning the sensors monthly, can prevent 80% of problems and save on high repair costs. Neglecting this even once could lead to serious accidents, so never take risks—safety always comes first.
