            Single phase electric chain hoists with compact and tough shape are made of high aluminum alloy shell or iron shell, which is light but hard. Our single phase electric chain hoists adopt three-phase induction or single phase induction motors, which are developed with new techniques for renewal and upgrading. All of them are in experienced strict quality management and are controlled from purchasing to delivery. For the sake of safety and reliability, these type of electric chain hoists are equipped with sensitive steady electro-magnetic braking device-inverse service and sequence protecting device-limit switch with lowest repair rate. 

             The  principle of phase change is to use 1 phase, also called “split-phase” capacitor motor or use VFD then change 3 phase to 1 phase, the advantage of using VFD is more reliable and safety, but the disadvantage is the  price is much higher than with capacitor motor. While considering the high efficiency and reliability of single phase, it is recommended for customers to use VFD to achieve the exchange of 3 phase and single phase. Also, it can automatically keep the output voltage stable when input voltage fluctuating. The primary difference between single phase and three phases lie on voltage that received through each type of wire. 

           All in all, this kind of single phase electric chain hoists can meet the needs for a large segment of industry. The convenience of the electric chain hoist is the difference between an easy load in, and a larger labor call under many circumstances. The starting torque of single phase induction motor is low, whereas the starting torque of three phase induction motor is high. One of the greatest advantages is that the single phase motors are easy to repair and maintain while that of three phase motor is relatively difficult and more expensive. Therefore, due to the single phase motors are simple in construction, reliable and economical as compared to three phase induction; we strongly recommend you use single phase electric chain hoists. Continuous working time is 15 min for normal iron cover single phase electric chain hoists and 30 min for aluminum alloy one, and only with hook suspension type for single phase with capacitor motor is available, but none with electric trolley type since there is no single phase for electric trolley.

           Designed with assessing method  for insulation system according to international practice and adopted with F class insulation, it enhances greatly safety and reliability of motors. And the surface of single phase electric chain hoists is 3 layers of staying varnish painting by best painting technic to keep shining and durable. Also, the lever block, lifting motor, end beam, single/double-track trolley and other related accessories are available. With the supporting multiple frequency setup methods and speed trace function, it can restart smoothly restart the running motor and with advanced winding, painting, assembly and packing, we will provide you with the comfortable products with best performance and convenient operation.

           We offer customers the entire lifting system solutions, different design and price choice according to your requirements. The advanced and automated machines such as swing punching machines, stators and speed punching machines to form the rotors in one piece can be achieved. Moreover, we can produce nice appearance and good performance motors while decrease the labor cost and mechanical loss with automated packing equipment. The after-sale services are provided and all electric chain hoists parts are auto-tested by world first-class test machine and we always insist on the most favorable price and highest quality guarantee to every our customers. We are also responsible for any problems if it is resulted by our reasons such as give the compensation to you.

           Single phase electric chain hoists are also called 1 phase electric chain hoists, one  phase electric chain hoists, single phase hoists/Trolleys, three phase VFD trolley hoists, single phase VFD trolley hoists, single-phase electric chain hoists with two value capacitor.   

         Single Phase electric chain hoists are widely applied in double beam cranes, gantry cranes, bridge cranes, tower cranes, single grinder cranes, lifting platforms, small cranes, monorail beams, industrial sites, air-compressors, pumps, fans, compressors, pumps, other mechanical equipment, agriculture equipment, lifting planks, decorations of construction, farming machines, low buildings, building services, manufacturing industry, small machines and other fields and areas. They are durable at hard environment with chemicals, rain and sea.

           Fortunately, there is a better way to solve this dilemma. Because a VFD rectifies each pair of phases to DC, then inverts the DC power for the three-phase output, a VFD can be used with single-phase input power to operate a three-phase motor.

4. Limit switch
           The equipment of limit switch is aimed at ensuring the motor stop automatically.  With up and down limit switch, it can prohibit the chains from exceeding for safety. In case of sudden emergency or the overload risk, the limit switch works well to protect the hoists from damage and for ensuring the safety.

The motor are designed as fan cooled, totally enclosed, squirrel cage type and noted for their novel design, compact structure, beautiful modeling, high efficiency, large torque, excellent starting performance, etc. The motors coils are special manufactured by hand with unique processing technic and they have super quiet voice and long service life with easy heat dissipation. These  series motors can be widely used as driving equipment of various machineries, same as, machine tools, blowers, pumps, compressors, transporters, agricultural and food processing. A single phase motor has just one wire wound on all the poles of  the stator while in three phase construction, 3 wires that supplied by a sinusoidal varying A.C, are distributed equally and wound on the poles of the stators. The one phase motor works on the 1-phase 220V AC supply only, which  requires two wires to complete the circuit that are live/mains & neutral for return path.
           There are several types of single phase motors as follows
           ①Spilt phase induction motor
           ②Capacitor start induction motor
           ③Capacitor start capacitor run induction motor
           ④Shaded pole induction motor
           The 3-phase motor works on such  as 3-phase 415V AC supply only which requires 4 conductors consisting as 3 mains & one neutral. Due to this, the maintenance is difficult and the network is complex but it has high efficiency and reliability. Therefore they are mostly used in industry for doing jobs which requires high power.

The chain container is standard equipment and is molded with thick polypropylene material or fabricated from steel to securely contain the chain and chain lubricant. Furthermore, optional containers are available for long lift applications.

8. Side magnetic braking device
           Side magnetic braking system is designed for ensuring the instant brake in order to guarantee the safety and avoid the emergency when the power is off. And with the mechanical braker and dual braking system, it has much more for safety. The internal brake unit for inverters of power 0.75KW-18.5KW has been deployed and the external braking resister can be connected outside for quick stop. The cone type brake is operated by a powerful pull rotor supported by magnetic force. The brake is adjustable to extend the life of the brake lining.

9. Inverse phase sequence protecting device
           The use of inverse phase sequence protecting device is controlling the circuit in case of wiring error while power on. Equipped with the friction clutch--- an overload-protection device idling the motor when overload and upper limit switch, the two function prevent the single phase electric chain hoists' body and load or load chain  from being damaged. In addition, the upper limit switch will activate and stop the hoists motor in the up direction preventing unnecessary clutch wear when  the load is lifted to high hook.

Tips: Single phase VS Three phase
             A. Single phase
           Single phase also called ‘residential voltage’ is more widely available in residential settings that most homes use it (it’s the power present in wall plugs),relies  on two wire conductors to distribute power, creating a single sine wave (low  voltage). Single-phase wire has three wires located within insulation with two hot wires and one neutral wire providing the power. Each hot wire provides 120volts of electricity and the neutral is tapped off from the transformer. The type of circuit using hot and  neutral wires is why it is commonly called a split-phase circuit. The single-phase wire has the two hot wires surrounded by black and red insulation, the neutral is always white and there is a green grounding wire.
           The motors are driven by pulsating torque just like a pulsating shower head, experiencing more interruptions in electrical flow and requiring capacitors and start switches with extra parts that need to be monitored. The single phases are widely  applied in small business, homes, non-industrial businesses, residential settings, small ponds, With fractional or low horsepower units (less than 5 HP),  which is able to supply ample power for most smaller customers,
           A single phase motor draws significantly more current than the equivalent 3-phase motor, making 3-phase  power a more efficient choice for industrial applications
           Some characteristics for single phase:

Motors require capacitors and/or start switches-- extra parts that need to be monitored

Experiences more interruptions in electrical flow

Motors have a shorter lifespan

B. Three phase
             Three phase is most commonly used at commercial/professional sites relies on three  coils mounted on the rotor at 120 degree intervals that are less expensive to operate than single phase power units, which produce three sines wave voltages (high voltage). The three phase power is supplied by four wires with three wires carrying 120volts of electricity and one neutral. Two hot wires and the neutral run to a piece of machinery requiring 240volts of power. Compared to single phase, three-phase motor is more efficient and with a smooth and continuous flow of power, some convert 97% of electrical energy into useable mechanical energy.
           The motors will experience rotation issues if installed improperly, the three phases are widely applied in commercial or professional sites, larger ponds, large businesses, industry and manufacturing, With any high horsepower unit (5 HP or  more), It’s used universally for power distribution.
           Imagine one man pushing a car up a hill; this is an example of single-phase power. Three-phase power is like having three men of equal strength pushing that same car up the same hill. The three hot wires in a three-phase circuit are colored  black, blue and red; a white wire is the neutral and a green wire is used for the ground.
           But  you need to check with your local company to see if it is available for three phase power since it isn't available at all locations and costs will be much higher when installing three phase power, Discovering which type of wire is being used is easily done. First look at the wires and see how the number of wires inside the outer insulation, You can also check the voltage.
           Some characteristics for three phase:

Allows for longer cord lengths/cable runs

Motors have a longer lifespan

Increasingly popular in power-hungry, high-density data centers

Expensive to convert from an existing single phase installation, but 3-phase allows for smaller, less expensive wiring and lower voltages, making it safer and less expensive to run
