Maintenance and inspection of wire rope slings

(1) run

The speed of the steel wire rope should be stable during operation, and it should not exceed the load to avoid impact load.

(2) Maintenance

The wire rope has been coated with enough grease during manufacture, but after running, the grease will gradually decrease, and the surface of the wire rope will occupy dirt such as dust and debris, which will cause wear and tear of the wire rope and sheave and rust of the wire rope. Clean and oil. The simple method is to use a wire brush and other corresponding tools to wipe off the dust and other dirt on the surface of the wire rope, apply the heated and melted wire rope surface grease evenly on the surface of the wire rope, or spray No. 30 or No. 40 engine oil on the surface of the wire rope , but do not spray too much and pollute the environment.

(3) Inspection records of wire rope slings

The use of wire rope slings must be regularly checked and recorded. In addition to the above-mentioned cleaning and refueling, the content of regular inspections should also check the degree of wear, broken wires, corrosion of the wire rope, hooks, rings, lubricating wheel grooves, etc. Condition of wear of consumable parts. Any abnormality must be adjusted or replaced in time.

Selection of wire rope slings

(1) Corresponding professional steel wire ropes should be selected for elevator and aviation steel wire ropes

(2) Corresponding special steel wire ropes should be selected for high-lift construction tower cranes, etc.

(3) Steel wire ropes for cranes, piling machines, drilling rigs, electric shovels, excavators and other machinery with low lift require wear resistance, fatigue resistance, and good impact resistance, and structural steel wire ropes such as 6*29Fi or 6*36SW can be used

(4) For equipment operating in high temperature environment or requiring large breaking load, steel wire rope with metal core can be selected

(5) Steel wire ropes for shipping, ships, fisheries, and tying timber are required to be corrosion-resistant and soft, and Class A galvanized steel wire ropes with structures such as 6*19, 6*24, and 6*37 can be used

In addition, the tensile stress of the steel wire rope should be selected according to the load used and the specified safety factor, and the appropriate strength level should be selected, and high strength should not be blindly pursued. In short, according to the characteristics of the equipment and the working situation, the appropriate wire rope should be selected to ensure safety, prolong service life and improve economic benefits.

We ship new galvanised hand chain, packing is bag in barrel, then on steel pallet. 

Chain rigging / Chain sling

Overview: Chain rigging is composed of ring chains, rings, hooks and other accessories. It is a metal sling. It is divided into 60 grades, 80 grades, 100 grades and 120 grades according to the carrying capacity. The higher the level, the higher the load capacity of the chain of the same specification.
advantage:

1. High carrying capacity
2. Good safety, breaking elongation ≥ 20%
3. Various combinations, strong versatility and interchangeability
4. Adjustable length, easy to store
5. Long service life
6. Wide temperature range
7. Easy to detect, convenient and fast

shortcoming:

1. The price is higher than that of slings and wire ropes

2. Heavy weight

The falling of the hook will bring great safety hazards to people's personal safety. Before and during the operation, any factors that may affect the safety of the hook should be paid attention to:
1. Irregularity of the hook
1.1 Risks caused by irregular design, such as failure of overload protection, unreasonable selection of spreaders and slings, etc.;
1.2 Manufacturing defects and installation defects, etc., make the equipment with hidden dangers put into use.
2. Human unsafe behavior
2.1 It is characterized by unskilled operation and lack of necessary safety education and training;
2.2 Working without a certificate;
2.3 Violations of regulations and disciplines, reckless behavior, and bad operating habits;
2.4 Misjudgment of operation, unclear command signal.
3. Environmental factors
3.1 Unfavorable environments that exceed safety limits or hygiene standards, such as lifting operations in environments with high dust, high temperature, high humidity, low temperature, high noise, windy days, and poor lighting, will distract attention and directly affect the response of operators The stability of ability and technology will increase the chances of misoperation and illegal operations, leading to accidents.
3.2 Poor working environment will also reduce the function of the crane system itself and even accelerate the failure of parts (components), becoming one of the unsafe factors.
4. Flaws in safety management
4.1 Lack of crane management, inspection and regular safety performance inspection;
4.2 There is a lack of safety education and training for relevant personnel, formulation of crane safety operation regulations, establishment of reward and punishment system for violations, and accident emergency plan;
4.3 Lack of regular inspection of lifting equipment and lifting aids Lack of effective monitoring and management.
In short, strengthening the safety education and training of crane-related personnel, and conducting regular inspections of the safety performance of cranes in use (including lifting aids) are necessary guarantees to reduce the occurrence of accidents caused by crane hooks and falling objects.

Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance.
Electroplating is further divided into specific processes such as copper plating, gold plating, silver plating, chrome plating, nickel plating and galvanizing. In the field of manufacturing, especially galvanizing, nickel plating and chrome plating are the most widely used.
1. Galvanized
Definition: Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and anti-rust effects.
Features: low cost, general corrosion resistance, silvery white color.
Applications: screws, circuit breakers, industrial supplies, etc.
Including white galvanized, color galvanized

2. Nickel plating
Definition: The method of plating a layer of nickel on metal or some non-metal by electrolysis or chemical method is called nickel plating.
Features: beautiful, can be used for decoration, high price, slightly complicated process, the color is silvery white and yellowish.
Application: Energy-saving lamp holders, coins, hardware, etc.

3. Chrome plating
Definition: Chromium is a bright white metal with a slight blue color. The method of plating a layer of chromium on metal or some non-metals by electrolytic or chemical methods is called chrome plating.
Features: There are two kinds of chrome plating, the first one is for decoration, the appearance is bright, the abrasion resistance is better, the anti-rust ability is not as good as galvanized, and it is worse than oxidation; the second one is to increase the hardness and wear resistance of metal parts, etc. , which is the functionality of the part.
Application: Bright decorative parts, tools, faucets, etc. on home appliances, electronics and other products.

The most basic difference between the three electroplating
1: Chrome plating is mainly to improve the surface hardness, beautiful appearance and anti-rust. Chromium plating has good chemical stability, and it does not act in alkali, sulfide, nitric acid and most organic acids, but it can dissolve in hydrohalic acid (such as hydrochloric acid) and hot sulfuric acid. Because chrome does not change color, it can maintain its reflective ability for a long time when used, which is better than silver and nickel. The process is generally electroplating.

2: Nickel plating is mainly wear-resistant, anti-corrosion, anti-rust, generally thinner, and the process is divided into two types: electroplating and chemical.

3: Galvanized is mainly beautiful and anti-rust. Zn is an active metal that can react with acid, so it has poor corrosion resistance and is the cheapest of the three.

The difference in cost: Chromium plating is the most expensive, followed by nickel, and zinc is the cheapest. Among them, rack plating and barrel plating are also distinguished. Rack plating is expensive and barrel plating is cheap.
