Brief introduction of electric chain hoists

Electric chain hoists made in china are a type of lifting equipment used for lifting or lowering a load with a drum or lift-wheel around which chain wraps. these hoists not only lift the expected weight, but also have the correct voltage, lifting height, motor speed, beam size and duty cycle, which will make the electric chain hoist a worthwhile investment in productivity. Besides, they provide reliability in terms of their design, technical innovation and high-quality parts.

The basic electric chain hoist has two significant characteristics, including lifting medium and power type. The lifting medium is wrapped around a drum and raised by a pulley with a special profile. The power can commonly mean electrical but not hydraulics or air driven motors. Hoists can be constructed as one integral-package unit which is designed for cost-effective purchasing and moderate utilization. They can also be built as a built-up custom unit aimed for performance and durability. In addition, as for electric chain hoists, packages units are considered as being designed for light to moderate usage and built-up units are designed for heavy to severe service. 

Electric chain hoists are available in different types of constructions and configurations. They tend to be further defined in three main areas. One is operation, which defines the type of power used to operate the hoisting motion. Second is lifting medium, which represents the type of component used to transmit and lead to vertical motion of the hoist load hook or hoist load block. Third, suspension defines the type of mounting or method used to mount or stop the hoist. Hook mounted, lug mounted and trolley mounted comprise of common suspension types. Thus, when referring to electric chain hoists, the above various types of constructions and configurations need to be considered.  

In details,1st, electric chain hoists are equipped with patented Automatic Adjusting Brake for added safety and easier maintenance. 2nd, Reserve phase inspection relays are able to take the circuit in control when reserve phrasing, but not suited for the three phase models of 250 kilograms and 500 kilograms and single phase models. 3rd, Push button switches interlocked mechanically are made of rain-proof plastic which has severe impact and corrosive atmosphere resistance. Also, the 24 voltage control circuit decrease shock hazard to the operation. Specially, with the emergency stop button, electric chain hoists can be stopped in the cases of emergency that may result from overdrive or erroneous operation. Furthermore, upper and lower limit switches have the ability of interrupting motor power to prevent hook chain kink. Ramhoist overload limiters are a unique and patented overload protection device, which is available on all required models.    

There are four main options of electric chain hoists. One is Dual Speed which is a relative more cost effective option, but it only has a single voltage. However, most of the users prefer to have the option of dual speed control on all functions of motor. Chain Contain is a collection bag or box which collects the excess slack load chain and prevent it damaging the load when released from the hoist body. It's always been recommended that this is a cheap but effective option as you choose to ass a slack chain collector. Users can set extremely accurate positions for maximum and minimum hook paths by using the upper and lower limit switches which are offered as standard on some hoists and optional on others that ensures the users will not carelessly lift or lower the load too far and unintentionally damage something important. This kind of china hoists are often used to avoid bulky loads from damaging the hoist body. Finally, Radio Remote Controls are an alternative to wired pendant control. Buyers can specify a radio control system which enables users to stand at a remote and safe place from the load. This may help operators see from a better angle of the load.       

 A variety of applications of electric chain hoist are efficiently provided for general machinery, automobile, manufacturing plants and so on. In these industries, electric hoists can be used on overhead cranes, workstation cranes or jib cranes. The versatility makes them an ideal solution for many lifting applications. Moreover, electric chain hoists' apply is from basic to the third industries, such as retail warehouse and stores.
