What Causes the Tail Lift to Drop Down?
4 Answers
Oil cylinder piston seal performance degradation or valve leakage can cause the vehicle tail lift to automatically descend. Under normal circumstances, many seals can hardly guarantee absolutely zero leakage over extended periods. If the lift drops only slightly over a full day, it may not be an issue. However, if it descends a noticeable distance within a short time, the cause should be investigated. Below is relevant information about tail lifts: 1. Function: Also known as vehicle-mounted tail lifts, these are hydraulic lifting and loading devices installed at the rear of trucks and various vehicles. 2. Advantages: Tail lifts use the vehicle's battery as a power source, featuring environmental friendliness and ease of operation. In today's global context of energy conservation and emission reduction, their advantages become even more pronounced, making them essential equipment for modern logistics transportation.
The tailgate keeps dropping down, a problem I've seen many times, mainly due to failed support gas struts. The gas struts are filled with gas, but over time, they leak and lose the strength to hold the door up, causing it to slowly slide down. Additionally, rusted and worn door frame hinges becoming loose can also lead to instability. If the latch isn't secured properly or is broken, the door may automatically open and slide down. Just last month, a car came in because the support strut had aged and cracked, letting all the gas escape, causing the tailgate to sink straight down. This is quite dangerous, especially when you're loading or unloading items—the door could suddenly drop and hit your feet or belongings. It's advisable to regularly check the gas struts for any oil leakage or loose hinges and replace them promptly rather than trying to tough it out. Take it to a reliable repair shop for a proper check-up; don't wait until something bad happens.
My car also experienced the annoying issue of the tailgate constantly dropping down. The problem was that the gas struts were too old and no longer functioning properly. These struts usually help hold the door steady, but over time, the internal seals wear out and leak, causing them to lose their support and the door to slide down on its own. Additionally, loose or rusty hinge screws can make the door even more unstable. When I got it fixed, I found that worn-out latch slots were also part of the problem, making it hard to keep the door securely closed. This issue is quite frustrating—imagine loading some cargo and suddenly the door drops, damaging everything inside. Now, I make sure to have the mechanic check the condition of the struts and hinges during annual maintenance, replacing them early to avoid bigger problems. Handling it yourself isn’t too difficult either; replacing a set of struts costs just a couple hundred bucks—don’t wait for a small issue to turn into a major headache.
The most common reason for a tailgate dropping is faulty gas struts. These struts rely on internal gas pressure to function, and after years of use, they can lose pressure and strength, causing the door to slide down. Rusted door hinges or loose screws can also make the door tilt and drop at an angle. From many cases I've studied, aging latch mechanisms are another key factor - worn catch grooves prevent proper closure, leading to automatic opening. Don't underestimate this issue; if the door suddenly falls while opening, it could injure someone or damage property. Get it checked immediately. First inspect the struts for oil leakage signs, then test if the door moves tightly when pivoting. Minor repairs can fix this - don't skimp on this maintenance.
