Lifting and weighing technology

     In recent years, the experts pointed out, material handling engineering technology is a modern industrial weakest, the most urgent need to address one of the areas, but it is also the most potential,hoist equipment the most promising areas. Proposed material handling technology is the third profit source concept. Material handling machinery usually includes lifting machinery, transport machinery, handling machinery, warehousing machinery, industrial handling vehicles and hydraulic machinery of 6 categories of products. In my country, material handling machinery commonly called lifting and transport machinery. Since lifting has many varieties, strong function, the role of other characteristics, in material handling machinery in a dominant position, is the first application of weighing technology material handling machinery.
Weighing technology in lifting machinery application history. Lifting machinery (such as: electric hoist) is a kind of intermittent operation mode of the material for lifting, moving down and horizontal handling equipment. In order to make the crane during the completion of the job at the same time to be hanging materials weighing,wire rope winch people consequent lifting machinery fitted in the ideas and aspirations of the weighing device.
Lifting applications weighing technology history over 200 years. In Munich Bavaria BIPM, the preservation of a 1780 weighing about loads wall hanging spring balance; there is a station in Hamburg in 1760 fixed jib jib crane, which is equipped with a 1858 top decimal scale manufacturing. In the first half of the 19th century, cranes (crane) scales on the "Swedish ship scale" is famous for the name. In 1932, a crane with a sling scale errors have been able to reach either a load of less than 0.2%, resulting in a type approval.
From 1986 onwards weight limiter first advent of the end of 2006 to create about 200 million yuan of sales value, and even national standards legislation have proved the fact that not only the starting weight limiter manufacturer has brought huge economic benefits also produced an extensive and far-reaching social benefits.
Currently, a new generation of large-scale and efficient crane electrical control device has been developed for all-electronic digital control system,wire rope hoist in particular the application of modern industrial weighing technology has become involved in material handling lifting decisive parameters obtained during an important measurement part, is effective in creating the basis for the third profit source and protection.

Distinguish the quality of electric chain hoist observe the arrow keys, etc.

We certainly do not remember how electric chain  lift hoist  should be installed today will tell you how to install the electric chain hoist, so that we can be more understanding of the electric chain hoist, also at the time of purchase to know its structure, so as to better law and order to its quality.

Electric chain hoist is often used inside the workshop lifting tool, this small volume, light weight, easy installation, operation and lifting hoists are very stable, has begun to replace bulky electric hoist, electric and CD Hulu will slowly be replaced. In the purchase of electric chain hoist before.

Can be distinguished according to the following quality electric chain hoist, first after power control electric  wire rope hoist  to move around and observe the arrow keys are correct, while paying attention to running up and down stops, if there is the sound of brakes, another stop watching after the chain have declined, and if so, that friction plate too loose, or not installed properly. After these there is no problem, click the up and down keys, observing run distance, the smaller the distance the chain hoist as possible. Use Tips: In some factories or workshops, sometimes you need to run relatively small distances, such as installation or butt,wire rope winch you need to hoist slowly raised or lowered to facilitate calibration and installation, but single-speed electric chain hoist majority, two-speed sometimes slow speed of installation can not meet, this time you can press the button a little way, that tap stopped, time is very short, so that relatively small range of movement can be calibrated after every click once, and so on, will equipment installation was successful. This is why the choice of electric chain hoist when lifting point distance by checking the reason, in principle, the landing distance as small as possible.

Wire rope pulling hoist wire rope maintenance and inspection

Have been painted in the manufacture of wire rope enough grease, but after running  lever hoist   grease will decrease gradually and the rope will occupy the surface of dust, debris and dirt, causing the wire rope and wire rope sheave wear and rust, so should be regularly cleaned and refueling. Easy way is to use a wire brush and other appropriate tools wipe rope surface dust and dirt, the surface of the heating and melting of the wire rope grease evenly on the surface, can also be put on the 30th or 40 engine oil pouring spout on a wire surface , but do not spray too much pollution.

Use rope must be checked regularly and make a record, regularly check the contents of the fuel in addition to the cleaning, we must also check the degree of wear of steel wire rope, wire break situation, the extent of corrosion as well as hooks, rings, round the lubrication grooves and other vulnerable parts wear. Abnormal situation must be timely adjustment or replacement.
wire rope winch wire rope inspection:
1, wire rope specifications, models should meet the design requirements, and pulleys, reels match and correctly reeved, wire rope should be firmly fixed, and reliable.
2, the plate is fixed, the plate number three, roll rope fixtures should prevent loose or self-tightening performance.
3, the metal compression joints are fixed, the joints should not have cracks. Fast fixed wedge, wedge sets should not have cracks, wedges should not be loose. Shengka fixed, Shengka installed correctly, the number Shengka should meet "check compliance" requirement.
4, in addition to a fixed number of turns of wire rope, the drum should be retained for at least two laps as a safety rope circle.
5, the rope should be oiled, and should not be rubbing metal structure
6, the rope should not be kinked, crushed, bent, broken stocks, cage-like distortion, broken cores deformation.
7, rope diameter reduction of not more than 7% of the nominal diameter,
8, the rope should not exceed the number of broken wires "check gauge" value.

Finally you are prompted rope pulling Hoist equipment  during operation speed and stability should not exceed the load operation, to avoid shock loading.
