Can electric gourds be controlled by PLC
can Electric hoist crane control system design based on PLC, with the scientific and technological progress and economic development, the application of electrical energy is more and more widely, electrical production, transportation and distribution of electricity and application plays a role control, adjustment, test and protection. The introduction of PLC makes electrical control easy and reliable.
Electric hoist crane, also known as electric hoist is a small-sized lifting set each, are widely used in weight lifting, lowering, translation handling, can reduce labor intensity, improve production efficiency, will improve the working conditions of the machinery, such as in factories, mines, station, port, warehouse, construction of divination, hydropower station such as applied in the production department. It has the characteristics of light weight, compact structure, small volume, convenient maintenance and durability. Main structure is the reducer, lifting motor, motor operation and firearms, cable wire, the broken drum device, hook device, coupling, introduction of flexible cable current device integrating force and braking. Its actuators consist mainly of ascending institutions and horizontal mobile devices, which are composed of cone-shaped motors, reducers and wire reel. Hoist motor reducer drive through wire reel, motor are turning or reverse, drag the reel, can make the hanging on the rope hook up or down, and realize the object of raising and lowering, horizontal mobile device by the motor, reducer, idler pulley, "work" word beam, etc. The moving electric block can be moved back and forth on the upper beam, and the motion of the two directions is restricted by the mechanism.
If this is the case, you should be able to clarify the detailed controls, the finer the better.
Why should you? One simple thing seems to be that money is crazy. You will be OK with the general electric block. The average electric gourd has no frequency converter. That's what China is. It can be improved with absolutely no technology.
With PLC is superfluous, electric hoist need, down, left, right, before, after, 6 contactor, a combination of a button or remote control, with PLC, the above device and cannot little, may also increase the intermediate relay, unless have unique request for electric hoist, such as automatic control, 300kg of electric gourd needs 0.5 tons 1.1 KW is the power of the step motor
