such as long-term placement

Manual hoist hundreds of thousands of species have much, but the method of maintenance is roughly the same, low humidity environment manual hoist should be how to care.

     1, manual chain hoist maintenance is a top priority, it is timely for the chain lubrication.

     2, such as long-term placement, should be handled in a timely manner and rust cleaning and maintenance wire rope hoist suppliers work and test run to see if it is working properly.

     3, regular maintenance manual hoist the main parts detection, and resolutely put an end to security risks appear.

     4, brake parts should be liftech 1 ton chain hoist kept clean, cut out regular checks to prevent sudden Zhidongshiling work occurred weights from falling.

     5, using the manual hoist rain, rain facilities should be set up.

     6, keeping dry parts chain hoists, chain hoists place after the operation is completed dry environment. Avoid high temperature and chemical areas.

wire rope winch taboo chain hoist hook to use

Is a professional chain hoists, lever hoists, cranes and other lifting equipment line tackle manufacturers, the following are the details related news hook hoists used four taboo.  Chain hoists enough material with high strength hook, and made of high alloy steel liftech small electric hoist aterials, the fracture does not occur in use, a higher safety factor. However, the use of hook should note the following points:
1, chip hook does not allow splicing. 
2, hook surface and internal defects without affecting its usability.
3, prohibiting the use of cast hook, so casting internal defects difficult to find and eliminate.
4, prohibiting the use of manufactured or repaired weldment hook, so there may be cracks in steel welding.
Avoid stress points and liftech strong electric winch support points are too far away; parts subject to vibration loads to avoid friction force transmission; avoid considering only a single load transfer; should not affect the working parts are ignored when the deformation of the force distribution; under impact loading parts Avoid just too large; affected parts should avoid stress becomes too rough surface, as well as the residual tensile stress.

Selection manual wire rope winch

 Near to Shanghai Yuan customers often reflect their relatively new chain hoist selection confused , I do not know how to choose the right type of chain hoists . For this new specially Shanghai Yuan summarize a few points in this for our customers choose chain hoist models specified when needed attention.
1 , understand their purchase of the brand chain hoists purposes. Whether regular use ? The maximum required number liftech steel beam clamps of pounds of chain hoists to pull ? And will tell Yuan 's new sales staff, they can recommend several suits your needs chain hoists model for you.
2 , has its own heart can withstand the price, whereby you can make a choice in the domestic chain hoists and chain hoists imported into , of course, does not necessarily imports than domestic well.
3, according to the above two points , after filtration , is also available for the rest of the liftech ratchet lever block model we choose so few , and this time we have to do is to test the mechanical properties of the final product , to see whether the product through the National Crane detection transport machinery quality supervision and Inspection Center , through inspection and in a little over cases still work to prove that subsection model reliable quality chain hoists , chain hoists the trusted brand .
After the above three we will find that the selection is so simple chain hoists , chain hoists other is in the process of selection must not be too hasty in order to avoid careless buy inferior products , to later use safety hazard .

wire rope winch Elephant chain hoist structure which featuresElephant Chain Block

Elephant chain hoist structure which featuresElephant Chain Block, Japan's leading process manufacturing, professional and technical level of assurance, the indicators are in line with national standards. After inspection of foreign companies to pay more, agreed that Elephant chain hoists materials and structures are quite liftech permanent magnetic lifter superior.
     Elephant Chain Block Features:
     Zojirushi high standard load chain, high strength, long life;
     Shell triangular, structural stability, internal stability components;
     Precision manufacturing stru liftech plate lifting clamp ctural components, safety brakes, durable and long-lasting
     Reasonable design, hand-pull small, with ease of use.
     Elephant chain hoist, the safety brake. Used in factories, mines, construction sites, wharves, docks and warehouses for installation of equipment, lifting goods, especially for open and no power supply, but also demonstrated the superiority

Device working principle is introduced

Device working principle is introduced: the ratchet wheel and pawl device belongs to ratchet stop the ratchet wheel and pawl, commonly used to prevent reversal system inverse as a mechanical device or for intermittent transmission.
Is one of the important component parts of chain blocks the ratchet wheel and pawl, some chain adopts single ratchet and pawl, others with double ratchet pawl, double double contrast in braking the ratchet wheel and pawl will be more safe.
Pawl upon ratchet SHH electric chain hoist intermittent movement of the parts. Pawl driven by connecting rod to do reciprocating motion, thus promote ratchet do one-way movement. Unidirectional movement to stuck ratchet, let the ratchet, reverse lock structure parts
Brake in crane operation mechanism, rotating mechanism and luffing mechanism, can make these wire rope electric hoist institutions to the desired accurately and reliably stop position. If installed in the lifting mechanism, in addition to load in a state of brake role, also can adjust rate of descent.
Brake according to the way of action points closed and open; According to the structure of the block type and belt type; According to the transmission points of mechanical drive, hydraulic drive and electric. In general, often closed double block block brake is more common in the crane. And manual hoist general friction ratchet type one-way brake, can brake under load, very convenient.
Brake lifting equipment is one of the important parts, rival chain also is so, its main function is to make the moving parts (mechanical) slow down, stop or keep the status, and other functions of a device
