The difference between electric gourds and driving
Electric gourd is the electric gourd that is electric, hang on the steel beam is monorail, the crane is on two steel beams, it is double track. Crane is a kind of lifting equipment, from the point of structure generally have a single beam, double girder, gantry, bridge, can walk in specific orbit, itself can lifting up and down. Lifting tonnage slightly higher driving generally there is main deputy winding, primary volume raised slowly , lifting tonnage, vice volume raise fall faster than the main winding, lifting capacity is small. Usually single-beam crane, electric hoist for more to hold, I think the electric hoist is a kind of simple driving form, also is a kind of driving.
A crane is a combination of lifting gear and walking gear. There are many kinds, such as 5 tons of driving, 5 tons / 20 tons of combined driving. It's a big tool. Able to walk all walks and lifting work. Electric gourd is the tool of lifting load, it is a kind of the tool that compares a single function, belong to small auxiliary tool. Maximum ability to move up and down in a single direction.
According to my observation The electric gourd is an electric gourd, which is attached to a steel beam and is monorail The crane is on two steel beams, which are dual-track
