Maintenance, common problems and countermeasures of mobile lifts
Oct 25, 2018

The principle of a mobile lift is the use of a hydraulic lift plus an electronic integrated controller. Easy to move up and down together to adjust the height in time, consider the safety of the general anti-skid insulation plastic water ripple plate, replace Bento, all beautiful and generous.

Do not manually lift ladders as hard as the real safety and convenience! Save time and effort! Regarding the mechanized construction enterprise, the technical condition of the construction machinery is good, the direct production of the enterprise can be the direct factor. In the construction machinery hydraulic transmission aspect, the hydraulic system's normal work is the outstanding technical condition. The qualified hydraulic oil is the reliable work of the hydraulic system maintenance, the correct maintenance is the basic operation of the hydraulic system.

For this reason, I have discussed the general working environment of hydraulic system maintenance of construction machinery according to the practice work.

1) Select the appropriate hydraulic oil The hydraulic oil in the hydraulic oil plays the transmission pressure, the lubrication, the cooling, the seal and so on effect, the hydraulic oil choice is not suitable, the hydraulic system pre-fault and the durability decline main reason. Hydraulic oil should be selected according to the rules of the random "operating instructions". When using substitute oil, its function should be the same as the original level. Different grades of hydraulic oil can not be mixed to prevent the hydraulic oil attack chemical reaction, function changes.

Dark brown, milky white, smell oil is metamorphosis oil, can not use.

2) prevent solid impurities from mixing with the hydraulic system Clean hydraulic oil is the use of hydraulic system life span. There are many precision couplings in the hydraulic system, some with resistance orifice and some vacant spaces. It is assumed that the intrusion of solid impurities will lead to precision damage, hairpin, oil plugging and so on, endangering the safety work of the hydraulic system. General solid impurity intrusion hydraulic system through: hydraulic oil is unclean; refueling maintenance, repair negligence, hydraulic components, such as chip removal.

Solid impurities can be prevented from violating the following aspects of the system:

A. When refueling Hydraulic oil is necessary to filter and refueling, refueling things should be clean and clean. In order to improve the speed of refueling, not to be able to remove the filter at the oil tank filling point.

Refueling personnel should use clean gloves and operating clothing to prevent solid impurities and fiber impurities fall into the oil.

B, Maintenance Remove the hydraulic fuel tank refueling cover, filter cover, detection hole, hydraulic tubing and other components, resulting in the system when the oil circuit to prevent dust, the removal of the site is necessary to thoroughly clean the talent opened. Assuming that the tank cover is removed, remove the dirt from the tank lid, loosen the fuel cap, remove the debris remaining in the connector (water can not be washed to prevent sink entry), open the tank before confessing to clean the lid. Assuming you need to use a wiping material and a hammer, you should choose not to wear fiber impurities and conflict rubber hammers attached to the material. Hydraulic components, hydraulic hose to be careful cleaning, installation after the use of high-pressure air monotonous. Select the packaging integrity of the genuine filter (the inner package is damaged, although the filter is intact but may be unclean). Oil cleaning together with the filter, using the filter before the use of cleaning materials, carefully clean the bottom of the filter shell dirt.
