Application of the technology in electric hoist hook

electric hoist trolley hook is a hook hoisting machinery in the most common. By electric hoistand pulley block part is hung on the hoisting mechanism of the wire rope or chain.According to the shape is divided into single and double hook hook, according to the manufacturing method for forging and laminated. three phase electric hoist hook is made of gold, steel, heat treated, chain, annealing, surface anti-corrosiontreatment produced, we understand in detail the application of the technology in electric hoist hook.

Electric hoist single hook has the advantages of simple manufacture, convenient use,but the stress condition is not good, mostly in the weight for the workplace 80 tons; big lifting weight often use force symmetrical double hook. Laminated hook which is composed of a plurality of cutting steel plate riveted together, the hook will not damage the cracks of individual plates, security is better, but the large self weight,mostly used in large capacity or the lifting of the molten steel ladle crane. The hook is often affected by the impact during the operation, the good toughness of high quality carbon steel manufacturing.

Mainly because of cheap wire rope hoist  in the use process, there are rarely have an overload situation. In this case, there will be deformation of the hook. And hook groupgeneral in the hanging point, is not easy to detect, if there are serious consequences.The hook is very easy to see the visual hook changes, minimize risk hook deformationalso continue to work. So the artificial let tensile strength hook group is different, it is necessary to.‍

suspended micro electric hoist

We all know that factories, mines, construction work is quite tired The labor intensity, is very large, especially in the installation of equipment, lifting Material, especially when loading, in order to simplify the manual labor, research Hair, made of suspended micro electric hoist to ease the work pressure Force, improve the operation speed, below we have to understand the product Advantages in performance of. 1, which can be connected to the power supply is very easy, no specialchain hoist 1 ton Requirements, the power plug is directly inserted can finish the homework in a common socket 220V voltage; 2, with the emergency stop switch and limit switch, when the unexpected happens, can occur in time to prevent the accident, Safety performance is very high; 3, with thermal protection device, because the power into power, residual energy is converted into heatchain hoist 2 ton Send out, with possible damage to the circuit, considering this point, design of the thermal protection device to prevent this from happening; 4, suspended micro electric hoist in addition to protecting the measures above, when the rope anti rotation or in other forms. Dynamic limit arm, will automatically stop lifting operation;lashing cargo 5, a safety hook lock 360 degree universal connecting hook pad, use more convenient.

Scope of application

Range of use of electric chain hoist is very wide, mainly used in large factories,warehouses, wind power, logistics, ports, construction and other industries, lifting or handling of goods can also be used for heavy lifting, convenient work or repair a large machine. Electric hoist chain by the operating personnel with the ground to follow the manipulation button, can also be manipulated by cable or in the control room(wireless) remote control. Ring chain electric hoist can be fixed suspension, also can be equipped with electric monorail trolley and hand push / pull monorail trolley used.‍

wire rope winch loads someone within range of activities

electric hoist lifting loads someone within range of activities, not operational. Personnel shall enter hoist lifting load range of activities
2 Do not operate just below the height of the load or carry loads in excess of the human head.
3, can not ride on top of the load lifting. Also, do not for support, lifting, take transport personnel purposes.
4, the body can not make ratchet lever hoist and trolley crash stopper and structures.
5, the electric hoist lifting loads in the state, do not be falling behind the operation moved. To operate, when electric wire rope hoists you move, please look at the front from the rear of the load, while the forward side of the operation.
6, do not hang lifting loads on other structures or cables.
7, when the load chain and chain wrapped zipper hand monorail car, please stop operating immediately, Untangle the knot.

o preventwire rope winch Manual Block to produce a chemical reaction the performance changes

Electric Stacker often use should pay attention to maintenance , especially for electric cars piled high maintenance system to do better , then how do electric stacker hydraulic system maintenance job?
 select the appropriate hydraulic oil:
Hydraulic oil in the hydraulic system of electric forklift trucks passing plays pressure , lubrication , cooling and sealing effect, the inappropriate choice of hydraulic oil hydraulic system failure and durability of the early decline. When grade hydraulic oil should 15 ton electric chain hoist randomly select "Manual" specified in special circumstances need to use on behalf of the oil, it should seek the same performance as the original grade performance. Different brands of hydraulic oil can not be mixed , to prevent hydraulic oil to produce a chemical reaction  the performance changes. Dark brown , white , smelly oil hydraulic oil is bad you can not use .2, to prevent air from entering the hydraulic system mini electric hoist Containing hydraulic fluid under pressure in the temperature volume ratio of 6 to 8% of the air pressure is reduced when the air is free from the oil , the hydraulic components bubble burst " cavitation " noise. A lot of air into the oil will cause " cavitation " phenomenon intensified, hydraulic oil compressibility increases, job insecurity, reduced efficiency , implementation of components appear to work "crawling " and other adverse consequences. In addition , the air also makes hydraulic oil oxidation, accelerated deterioration of the oil.

wire rope winch This is because the laser is directional

Ranging laser light is one of the earliest applications. This is because the laser is directional , high  brightness , good color and many other advantages . 1965 years ago the Soviet Union using laser measuring  the distance between the Earth and the Moon (380 × 103km) error of only 250m. After the Americans landing  on the moon in 1969 set the mirror on the lunar surface , but also with a laser to measure the Earth-Moon  distance , the error is only 15cm. [ 14 ] Although the high -precision laser distance sensor has been  listed for many years , but because of its price is too high , has not been widely used . Recently, due to  the significant permanent magnetic lifter decline in their prices , making it a cost-effective areas ranging approach. After  comprehensive consideration , we decided to take the lead in the industry of weight using laser distance  sensor for non-contact position measurement, this not only ensures the safety test accuracy and test  process can be slipped easily measure the amount of brake weights , lifting parameters such as speed and  position to solve the wire 20 , Southeast University, master's degree thesis ( 1 ) spatial segregation :  Let susceptible to interference away from the interference source crane trolley signal lines or circuits , this is the  most effective measures to suppress interference sources. Avoid parallel lines and the strong and weak  signal line signal lines away from strong electrical feeder lines must go alone . Must not be mixed with  the signal line to pull together ; must take the analog signal and digital signal lines separate line ;  avoid strong signal line parallel with the weak signal line , if the conditions as much as possible so that  the two orthogonal . ( 2 ) Screening: overcoming the electric-field coupling is the most effective method  of interference shielding . Because placed in the hollow conductor or metal objects are not affected by  external electric field . However, when an electric field coupling interference shield , the shield  conductor layer is preferably not connected at both ends
