Q:Which brand is better for imported rigging?: Germany's mechanical products are better, quality world-class, CarlStahl sling rigging is Germany's old brand.

Q:What is the safety factor of the wire rope as a motor lifting equipment, slings and slings?: 2. galvanized steel wire rope, including hot-dip galvanizing and electro galvanized two kinds, hot galvanized zinc layer is thick, long use time, galvanized thin, zinc layer thicker, corrosion protection ability is stronger. Because of the corrosion resistance of phosphating coating, the manganese phosphating coating steel wire rope can be used instead of some kinds of zinc coated steel wire rope, such as the B zinc coating in GB8918-2006.

Q:Why do not different kinds or different sizes of slings and slings are used together?: Or different specifications of slings and slings are used together; the carrying capacity of the sling shall not exceed the rated lifting capacity; the sling shall not exceed the safety load; the lifting crane shall check whether the connection point is firm and reliable

Q:Does the pressing rope have any influence on the tension value of the wire rope?: Lifting equipment commonly used wire rope varieties of phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope.

Q:What are the selection principles for lifting cranes?: Selection should take into account the performance of the crane (ie operation capacity), ease of use, hoisting efficiency, hoisting capacity and duration requirements.

Q:Do cranes have the same wire ropes, slings, slings and cables?: A steel wire rope is a common wire rope, and a sling is a special tool for lifting some goods. The sling is a sling tool made of wire ropes

Q:What is the name of the wire above the train?: The catenary provides 25 thousand volt power frequency alternating current for the locomotive, according to the locomotive model difference, adopts the direct step-down, the frequency conversion power supply or the AC and DC conversion power supply, this is mainly for the speed regulation convenience.

Q:How much is the crane arm of the tower from the residential building recently?: (1) the drivers and signaling personnel of the tower cranes must be specially trained and issued certificates by the relevant departments, and attention should be paid to whether the type of tower used by the driver is consistent with the actual tower type.(2) special person special plane management, Captain responsibility system, and strict shift shift system.(3) the newly installed or repaired tower crane must perform the machine test operation according to the specifications.(4) tower crane should keep a safe distance from overhead transmission lines.(5) driver's room should be equipped with fire extinguishing equipment.

Q:How do you tie the wire rope?: Manganese phosphating belongs to wear, corrosion, phosphating, automobile transmission, steel gear is through the manganese phosphating treatment, can ensure that the car gear for more than ten years without damage. Phosphating coating of steel wire rope China patent technology production, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just add the last bonderizing process, steel wire for rope wear resistance and corrosion resistance is greatly improved, the use of direct phosphating steel wire twisting steel wire rope. The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3-4 times the same structure of domestic smooth steel wire rope, wire rope surface is 2-3 times of imports, (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility, is currently the most advanced technology in the world of steel wire rope field. Manganese phosphating is bonderizing, can solve the problem of wire rope wear during use, smooth wire rope being eliminated, because the phosphating coating steel wire rope in short supply, the more sought after, need to ask a few companies.

Q:What tools are slings in lifting operations? What is the function of the slings?: A sling is also called a jack rope, a pair of rope or rope buckle. Hoisting works are more used, such as tying equipment, hanging blocks, stabilizing winches and so on. The utility model has the advantages of good quality and large elasticity, but the rigidity is large, and the bending is not easy, and once the bend is not easy to recover. Slings made of wire ropes of hemp core are not easy to work under high temperature.
