The ultra-low-hanging manufacturer believes The application scope of electric hoists is expanding rapidly, and they can be seen in a wide range of settings, including warehouses, workshops, docks, construction sites, and more. Generally speaking, electric hoist products include DHS electric hoist, DHY electric hoist, ghost head style Electric hoists, etc. Ghost-head style ring chain Electric hoists can be classified into stationary electric chain hoists, traveling electric chain hoists, and low-clearance electric chain hoists, among others.

　　1. Oil leakage from the electric hoist gearbox

　　 The ultra-low-hanging manufacturer believes This situation is quite common. First, inspect the gearbox housing or cover for oil leaks. The primary causes are casting defects such as sand holes, porosity, and slag inclusions. Next, check the oil level in the gearbox; if the oil level is low, replenish it promptly. The specific amount of oil to add and the interval between additions should be in accordance with the operating instructions for the Lion electric chain hoist. Don’t forget to inspect the gearbox vent. Every electric hoist gearbox is equipped with a vent, but the vent is very small. If it is not cleaned regularly over a long period, the vent can easily become clogged, leading to a pressure differential inside the gearbox and causing oil leakage. Therefore, the vent must be cleaned promptly. Begin by inspecting the chain case and the vent, then proceed to examine the gearbox housing.

　　2. Inspect the limit devices of the electric hoist.

　　 The ultra-low-hanging manufacturer believes The limit devices of electric hoists are essential for ensuring the safe operation of lifting equipment; therefore, they must be inspected during installation, commissioning, and maintenance. Particular attention should be paid to verifying that the limit devices are functioning properly, as failure to do so may result in the hoist deviating from its intended travel path when the limit is exceeded, potentially leading to accidents. In addition, operators must carefully control the hoisting speed as the hook approaches the limit device to prevent excessive speed that could make it difficult to stop in time and cause an accident. It is also imperative to provide operators with training on operating procedures and safety standards before they assume their duties.

　　3. Gear Inspection for Electric Chain Hoists

The ultra-low-hanging manufacturer believes Another key focus of the inspection is gear examination, to determine whether the gears are damaged. There are two main issues to consider: the gear itself and the tooth surface. In general, the gear body is more likely to fail during operation; excessive fatigue or overload can lead to gear fracture. Tooth-surface problems are mostly related to wear—for example, improper installation or commissioning of components can cause tooth-surface wear, or chemical reactions between the tooth surface and certain lubricants can result in corrosive wear. If problems are detected with the gear or its tooth surface, the gear should be replaced promptly to prevent more serious issues from arising.
