Mechanical screw jacks is a simple and convenient lifting tool, which is widely used in all works of life.The correct use and maintenance of the jack can prolong the life of the jack. The following is a summary of the maintenance method of the jack
Before the use of screw jack, the first to check whether the parts are in good condition, test the top when the hydraulic piston is normal jacking out retract;
When the jack will be heavy lifting, must be timely with support to support the heavy firmly (not to use the jack as a support);
In the process of jacking can not be used beyond the stroke, in order to prevent the damage of hydraulic jack and personal safety;
In order to extend the service life of the jack, refuse to use it in places with corrosive gas or corrosive liquid;
After use, the piston rod of the jack should be completely put back into the jack, and the hydraulic tubing should be removed and stored in a dry place in the dark.
Such as when using 32 ton mechanical lifting screw jack, do not use it in corrosive air or places, which are very harmful to the jack.
Easy to generate most of the corrosive gas is a chemical plant, the gas with acidic or alkaline substances, and the production material of screw jack is metal, metal hit these material, after a chemical reaction occurs, resulting in a corrosion phenomenon, corrosion happened once the screw jack, will certainly affect its use.
Corrosion rust after jack on the flexibility will be greatly reduced, when the operator in the operation of the arduous or can’t operation, if the screw severe corrosion, its bearing capacity will also reduce, if it is also in accordance with the original jack-up weight bearing ability, is a good chance to make jack bear, that the weight slip occurs, light property is damaged, heavy casualties are produced.
All of the above are the hazards of manual hand mechanical screw steel lifting jack in corrosive air operation. I hope to get everyone’s attention and safe and reasonable use of jacks.
