What should I do when the work platform lifts cannot be started?
Aerial work platforms, also known as aerial lifts or cherry pickers, are essential tools in construction, maintenance, and repair work. They provide safe access to elevated areas and allow workers to perform tasks efficiently and effectively. However, like any other equipment, aerial work platforms can experience mechanical issues that can compromise their performance and safety.
One common problem that aerial work platforms encounter is starting difficulties. When the engine of the aerial work platform is normal, the failure of the starter or the battery will make it difficult or even impossible to start the engine. It is crucial to understand the usage of the aerial work platform starter and battery to determine the fault location and perform the necessary troubleshooting steps.
First, it is essential to check the condition of the battery. If the battery has been used for more than 1 year, it may be damaged and cannot be used. The first step is to test the battery voltage with a voltmeter. If the voltage is below 12 volts, the battery may need to be charged or replaced. It is also essential to check the battery terminals and cables for corrosion or loose connections. If the battery is in good condition, the next step is to check the starter.
The starter is responsible for turning the engine crankshaft to start the engine. When starting, only the "clack" sound of the electromagnetic switch of the starter is heard, or when starting for the first time, the starter drives the crankshaft to rotate slowly for a few times, and then there is a "cluck" sound of the starter electromagnetic switch, but the crankshaft does not rotate, the fault may belong to the battery "breakage." If the temporary parking of the aerial work platform can be started every time, but the crankshaft can only be turned once when the parking time is long or the next day is started, it indicates that the battery is close to being scrapped and needs to be replaced.
If the starter suddenly turns weak or accompanied by the smell of burning rubber or smoke from the battery, the fault may be due to poor contact of the pole pile and the pole pile clip, resulting in heat and burnout. It is important to inspect the starter and the battery connections and make sure that they are clean and secure.
Another possible cause of starting difficulties is the starter drive gear and the flywheel ring gear of the engine making an idling sound when the aerial work platform is started. The reasons may be the deformation of the meshing cutting surface of the flywheel ring gear or the clearance of the starter drive gear and the flywheel ring gear is too large. If the two cannot be engaged, the engine cannot be started. It is important to inspect the starter drive gear and flywheel ring gear for damage and wear and replace them if necessary.
If the holding coil of the electromagnetic switch of the starter is wrongly connected to the power terminal, or the three wires on the key switch are wrongly connected, the drive gear of the starter will mesh with the ring gear of the flywheel and rotate together once the main power switch is turned on. If this kind of failure occurs, the judgment method is: when the key is in the "0" position, the starter drive gear does not rotate, and when it is in the "2" position, the starting motor drives the gear to rotate together with the meshing of the flywheel ring gear.
Lastly, if the engine cannot be started when the start switch is turned to the start position, and there is no other phenomenon, the key and switch may not be connected to the starting circuit due to wear, or the starter relay is not connected to the starter electromagnetic switch circuit, or the power switch is not connected to the main circuit. It is essential to check the starting circuit and make sure that all the connections are secure and functional.
