The working speed of the jib crane includes the lifting speed, the running speed of the trolley and the running speed of the large car. The choice of working speed depends on many factors.

First of all, it is related to the lifting capacity. The cranes with medium and small lifting capacity should choose high speed to improve productivity, and the cranes with large lifting capacity should choose low speed to reduce the driving power and improve the stability and safety of operation. The working speed also depends on the working level and usage requirements. Cranes with high working level, frequent use and high productivity are selected for high speed.

The working level of jib cranes is low, and the working mechanism used for adjustability operation can choose low speed; cranes only used for equipment installation and maintenance should choose low speed, and can also adopt double speed (fast speed, slow speed) and low speed according to needs. Or speed regulation. The use of frequency conversion speed regulation can make the working speed of 1:10 arbitrarily adjusted at the same time. The working speed is also related to the size of the crane’s service space. The high speed should be selected for the long running distance and large lifting height.

When the jib crane travel distance is short, it is not advisable to use high speed, so as not to start braking before the completion of the start. But with the development of modern industry. Cranes that do a lot of reprinting work are increasingly using high speeds. A large number of cranes for installation and maintenance use speed regulation. For some cranes with special functions, such as those used for work-piece quenching operations, there should be a rapid lowering device; for cranes with large lifting heights, in addition to appropriately increasing the lifting speed, it can also use low speed for heavy load and high speed for no load, or Take measures to obtain a higher rate of descent to increase productivity.
