3 ton overhead crane for sale

3 ton overhead crane belongs to light duty lifting device that handle loads for three tons. This crane usually is made into single girder overhead crane, for its lightweight lifting need. If you want to carry more heavy loads, you may need a double girder overhead lifting crane. There are sorts of cranes according to function, appearance, rated loads and crane girder. No matter which crane you want, we will give you a high quality product in cheap price.

You can choose the crane fits for your factory best referring to the pictures and parameters. Generally speaking, three tons overhead crane is single girder type, you can find other page on this site if you want have a look for double girder cranes. And crane manufacturer devotes itself to crane research for many years, we ensure you that you can get a high strength and inexpensive overhead bridge crane.

Working theory of electromagnetic 3 ton overhead crane

Electromagnetic overhead equipment use low voltage and electric current to control high voltage and electric current, which makes a small electric shock coefficient. Basically, this crane is machine that to transport loads based on electromagnetic principle. The main part of electromagnetic overhead crane is magnet, which can suck loads tightly after current on, then objects can be transported anywhere needed. If you want to low down loads, the only thing needs is making electric current off. The use of this crane is convenient, however, it cannot be used without current. You can use this crane to transport steel plate and iron materials.

This device transports loads using electromagnetic principle. Which means the overhead crane is able to produce huge magnetic field force. Tons of iron plate, wire and nail can be collected and carried with ease. To carry loads this way is not only easy to operate, but simplified. Moreover, materials in wooden boxed can be transported as well. When your crane is working, if the current of electromagnet coil does not stop, the loads sucked cannot fallen either. The invisible magnetic force is harder than solid chains. This crane has strong safety protection system, if there is no current suddenly, loads cannot fall immediately, and steel claws of crane will hold the loads tightly. One thing you should know when using this crane is that do not transport high temperature steel, for it cannot be magnetized under high heat.
