Why do you do the in-line inspection method for galvanised steel wire ropes for lift cabs?

Why do lift car galvanized steel wire rope of online inspection method Elevator car galvanised steel wire rope is a key load-bearing component in the software of the project building enhancement system, the personal safety and assets of the staff and his safety situation are immediately related. Therefore galvanized steel wire rope check is very must. Therefore, in the "lift safety regulations" standardized the safety performance of the lift car galvanized steel wire rope: the established requirements of the usual maintenance and inspection. However, in the lift use the whole process, the galvanized steel wire rope breakage produce the major safety accident also sometimes and cause. Nowadays the vast majority of the region to the engineering construction to improve the galvanized steel wire rope application on time to execute the method of dismantling and changing, in the galvanized steel wire rope application after a period of time, regardless of the galvanized steel wire rope has no damage, no matter how its situation, all replace out.

Knowledge of the internal condition of wire rope rigging

To carry out internal inspection of wire rope rigging is much more difficult than carrying out external inspection, but because of internal destruction (key by rust and fatigue caused by broken wire) is more secret, therefore, to ensure the safety of wire rope rigging application, must carry out internal inspection in a moderate position. The way to check the wire rope rigging: Clamp 2 fast clamps of suitable size 100-200mm apart on the wire rope rigging and rotate it backwards, then the strand will come off. The actual operation, must be very careful, in order to prevent the strand rope is moved too much to cause permanent deformation (cause the wire rope rigging structure destruction). The content of the inspection: after the small gap appears, use the probe such as the change awl to turn the strand rope and peel away the vegetable grease or other dirty things that obstruct the view, to internal wetting, stainless steel wire rust, stainless steel wire and stainless steel wire between the mutual fitness movement caused by scratches and other conditions to carry out carefully. It should be very noted that checking broken wire, must be attentive, because stainless steel wire broken generally not easy to warp up and not easy to be found.

Galvanised steel wire rope sets for sling operation

1, galvanized steel wire rope sets of equipment sling operating method applicable to inhibit steel wire rope rigging and insert braided steel wire rope rigging galvanized steel wire rope and aluminum alloy profiles to inhibit the connection head position has cracks or load deformation; insert braided steel wire rope rigging insert braided position has more serious draw off;. 2, galvanized steel wire rope complete sets of equipment lifting sling each end of spare parts damage, deformation, corrosion and other reasons and endanger all normal applications. 3, galvanized steel wire rope complete sets of equipment sling galvanized steel wire rope part of the specification reference galvanized steel wire rope quotation specification.

How to mitigate wire rope lifting chain damage

Lifting chains are very common in lifting and hoisting. However, due to material problems, lifting chains can be easily damaged, and this, coupled with non-standard application, has resulted in the early costing of many of the original cost effective products and increased application costs. What should we do to alleviate the damage of lifting chains? First of all, the tension of the lifting chain should be mastered. Many companies apply lifting chains, not tight is loose, too tight will cause the transmission chain output power to increase, and finally damage, too loose will cause the transmission chain jump chain, can not achieve the actual effect of application. Secondly, the oil should be dripped on time during the whole process of applying the lifting chain, which will not only increase its service life, but also further improve its working efficiency. Finally, the storage of transmission chain is also very important. Generally, all the chains are stored in dry and naturally ventilated areas, and the chains that are not used much should be maintained regularly with oil drops to prevent them from being leached.

What condition of the wire rope rigging should be stopped or serviced, dismantled and replaced

When the wire rope rigging has one of the following conditions, should stop using or overhaul, dismantle and replace, report the cost. No regularity all over the destruction: in 6 times galvanized steel wire rope diameter of the length of the scope, thus visible broken wire quantity exceeds galvanized steel wire rope stainless steel wire quantity of 5%. 2, galvanized steel wire rope part thus visible broken wire destruction: there are three above the broken wire set together. 3, cable eye surface appears centralized broken wire, or broken wire centralized in metal material waterproof casing, jointing place around, jointing coupling rope strand. 4, Galvanized steel wire rope more serious damage: in all parts of the evaluation galvanized steel wire rope diameter, specifications have been on the original outer diameter of 90%. 5, galvanized steel wire rope more serious rust: soft reduce, surface layer significantly not smooth, in the rust location evaluation galvanized steel wire rope diameter, specifications have reached not on the original outer diameter of 93%. 6, because of tie knot, distortion, extrusion molding lead to galvanized steel wire rope saki change, pressure broken, core destruction or galvanized 7, galvanized steel wire rope thermal destruction: because of induction of electric burning arc caused by galvanized steel wire rope burning, molten metal material liquid scalding, or long-term exposure to high temperature natural environment caused by the reduction of compressive strength. 8, the joint is more serious suffer extrusion molding, damage, metal material waterproof casing destruction (such as cracks, more serious deformation, corrosion) or diameter becomes smaller to the original 95% of the outer diameter.

How to maintain wire rope rigging

1, galvanized steel wire rope bending radius is too small, it will make galvanized steel wire rope early broken wire or rope core exposed, should pay attention to. 2, galvanized steel wire rope over sharp diamond angle, will make galvanized steel wire rope early broken wire or rope core exposed, should add protection wall angle maintenance . 3, steel wire rope rigging in connection with lifting hook, hook, sling, etc., is very easy to damage the position, can add ring set to carry out maintenance, increase the use of steel wire rope rigging period.
