The Chain Block components are made ​​of high quality steel

 1 Gear : International Standard gear steel increased abrasion resistance than ordinary gourd doubled more stable rotation , hand pull lighter.
2 chain : the chain of higher intensity ; adapt to sudden overweight job ; changing ordinary chain hoist to pull down only vertically , greater adaptation range .
 3 hook : high strength material foot hook , higher safety factor ; hook at the new design, so that the goods will  liftech strong electric winch be decoupled.
4 limit switches : limit switch hanging under the hanging parts , textile chain beyond to ensure safety.
5 parts : The main components are made ​​of high quality steel, the implementation of strict size, weight checks to ensure the performance of each component of the full play.
6 Body : slim design, innovative and generous appearance ; ergonomic, light body work activities of small liftech ratchet lever block interface , adapt to the environment .
7 spray : advanced spray technology, both inside and outside hanging plastic , then use a long table are new as ever .
8 Housing: pressed steel casing, solid in significantly lighter.
It has eight major characteristics of high-performance, high security and full of spirit , talent, a separate faction , allowing you to more easily facilitate the completion of the work , greatly reducing your labor intensity.

Chain Block Run institutions brake mounted on the crane

Run institutions brake mounted on the crane , luffing rotating bodies and institutions , these mechanical lifting devices  can accurately and reliably stop at the desired position . If installed in the lifting mechanism , in addition to the role played in the braking load state , but also to adjust the rate of decline of the object.
Brake action by way of closed and open ; according to the structure of the block type and belt ; by transmission of mechanical transmission , hydraulic and electric types . Generally , normally closed two- block brake shoe mostly common in crane . The manual hoist liftech small electric hoist generally use a one-way ratchet friction brakes , self braking under load , very convenient.
Brakes are very important parts of lifting equipment , hoist pull the opponent is also true , its main role is to make the moving parts of a device ( mechanical movement ) slow down , stop or remain stopped other liftech mechanical lifting devices unctions Baoding Hoisting Machinery Co., Ltd. Three Long Road 2014.03.12-14 participate in the Shanghai New International Expo Centre 25th International Hardware Fair , booth No. E5601, E5602, and friends are welcome to patronize . Three Dragon , Crane Co. [ 1 ] lifting gear product range : all kinds of jacks, chain hoists , electric hoists , chain hoists, explosion proof hoists, lever hoist , balancers, lifting chains , pulleys, pulley, tractor , shackles, bearings , lifting hook, sling . 2 sling : metal rigging : wire rope slings , chain slings , shackles class , hook type, hanging ( clip ) pliers , magnetic spreader etc. . Synthetic rigging : the nylon, polypropylene, polyester, high strength and high modulus polyethylene fiber material production with rope and rigging class .

we will in the Chain Block six areas to illustrate failed standard chain hoists

 Chain hoist maintenance work late Lubrication is very important one, in which there are many details lubrication aspects need attention, in addition to part of the taboo issues . Taboo 1, only in reverse chain completely stopped working after allowing lubrication . Taboo 2 , different grades of lubricating grease can not be mixed . Taboo 3 , moist places sodium based lubricants should not be chosen because of its absorbent and failure. Taboo 4 , not prohibited by product use and maintenance manual requirements for lubrication. Often inverted chain wire rope winch  can reduce component wear and ensure its rolling friction and sliding friction parts good run down the chain in order to improve performance and service lifeNecessary checks before using chain hoists Check before using chain hoists very necessary , we will in the following six areas to illustrate failed standard chain hoists .
1 , logo , no device number, load marked incorrect , illegible or missing.
2 attachment points gourd , gourd is not properly secured to the attachment point .
3 , all of the load chain links : links wrapped or twisted. Cracks , grooves, notches , sharp edge , or excessive wear of severe corrosion .
4 , active chain wire rope hoist manufacturers  edges , twisting , stretching, corrosion or serious cases may endanger the safety of users .
5 , hoist and hook rack , bolts , nuts or rivets loose or missing ; cracks or missing parts .
6, the load chain attachment points , the end of the fixed incorrectly ; severe corrosion ; cracks or excessive wear ; chain blocked or twisted . Baoding Hoisting Machinery Co., Ltd. Three Long remind you to be careful in the use of checks , checks to prevent improper because of a security incident...
