Concentrate on quality of the construction hoist and suspended platform, never forget original intention!

The importance of daily maintenance of the hydraulic system of the lifting platform

by:Powerston     2021-08-03
Clean hydraulic oil is the life of the hydraulic system. The hydraulic lifting cage platform is driven by steel wire ropes and is mostly used to transport goods. It is composed of tower, hanging basket, hoist, etc. The tower is generally a truss structure, which is pulled by cables to keep it upright. The hanging basket is welded with section steel and is a container for loading goods. The hoist is fixed on the ground, the wire rope is connected to the gondola through the pulley on the top of the tower, and the gondola is pulled to run up and down, and the operator controls it on the ground. The boarding bridge is used for bridge equipment between forklifts and trucks to facilitate loading and unloading of goods. Maximum dynamic load: 6T, maximum static load: 6T, maximum width: 2M, maximum length: 4M. There are many categories, generally divided into mobile docking bridges and fixed docking bridges. Conventional: solid tires with a length of 11M and a width of 2.1M. The hydraulic docking bridge is a special auxiliary equipment for fast loading and unloading of goods. Its height adjustment function enables a bridge between the truck and the cargo platform of the warehouse. The forklift and other handling vehicles can directly drive into the truck for bulk loading and unloading through it. Called the loading and unloading platform. There are many precision coupling parts in the hydraulic system, some have damping holes, and some have better damping holes. If solid impurities can cause tension, indexing, oil circuit, etc., the hydraulic system is operating safely. Generally, solid impurities are used to transform the hydraulic system in the following ways: hydraulic oil is heavy oil; auxiliary tools are powder metallurgy; careless maintenance; hydraulic components remelting, etc. Solid impurities can be prevented in the following ways. In the production process, hydraulic oil must be filtered and filled, and tools must be reliable and clean. Do not remove the filter of the fuel tank's air inlet to increase the speed of the fuel tank. Workers should use clean gloves and work clothes to prevent solids and fiber impurities from falling into the oil. 2. During maintenance, remove the hydraulic oil tank cover, filter cover, inspection hole, hydraulic pair and other parts to expose the system oil circuit and avoid dust. It must be thoroughly cleaned before it can be opened. For example, when removing the hydraulic oil tank cap, first remove the soil around the oil tank cap, loosen the oil tank cap, remove the debris remaining in the joint (do not use water to prevent water from the oil tank), and confirm whether there is oil stains before opening the oil tank cap . If you need to use a better material, you should choose a material that does not remove fiber impurities, and a special hammer with rubber. Hydraulic components and hydraulic hoses should be carefully cleaned, dried with high-pressure air and assembled. Choose the original filter element with good packaging (the inner packaging is damaged, although the filter element is intact, it is ok). When replacing the filter element, clean the filter at the same time, and apply the material to the bottom of the filter housing before installing the filter element. 3. The clean oil of the hydraulic system should be of the same grade as the clean oil used in the system. The temperature of the oil should be between 45°C and 80°C, and the impurities in the system should be removed at a high flow rate as much as possible. The hydraulic system needs to be cleaned more than three times. After each cleaning, when the oil is hot, the system will be used up. After cleaning, clean the filter again, replace the new filter element, and fill in new oil.
In an age when suspended working platform is increasingly important, the researchers believe manufacturers should pay close attention to their results.
