As we all know that unning speed of overhead crane refers to the speed corresponding to the moving mechanism of the trolley and the trolley when it is running at the rated speed of the dragging motor, in meters/minutes (m/min). The running speed of the trolley is generally 40~60m/min, and the running speed of the trolley is generally 100~135m/min.

And the boost speed of 15 ton bridge crane, in general, the lifting speed does not exceed 30m/min, depending on the nature of the weight, weight, and lifting requirements. There is also an empty hook speed for the lifting speed, the non-production time can be shortened by the empty hook speed, and the speed of the free hook can be as high as twice the rated lifting speed. There is a special case of lifting speed. The low speed when the weight is close to the ground is called landing low speed to ensure personal safety and cargo safety. The speed is generally 4~6 m/min.

In addition, the working type of 15 ton bridge crane is determined by its load rate and the degree of heavy work. It can be divided into four categories: light, intermediate, heavy, and heavy.

(1) Lightweight. Operating speed is low, use less time? There are few full-load opportunities and the electricity continuity rate is 15%. For a stress-free and heavy work place. For example, it is used as a crane for installation and maintenance in hydropower stations and power plants.

(2) Intermediate. They often work under different loads, medium speeds, less heavy work, and 25% power continuity, such as cranes for general machine shops and assembly shops.

(3) Heavy. Heavy work, often working under heavy loads, with a continuity rate of 40%, such as cranes used in metallurgy and foundry shops.

(4) Extremely heavy. It is often used to lift the rated load, the work is particularly busy, and the continuity of electricity is 60%, such as metallurgical bridge cranes.
