Key factors influence crane working speed

Crane working speed includes lifting speed, trolley travelling speed, crane travelling speed. Working speed is influenced by many factors.

First, it is related to the weight. The crane with small and medium lifting can adopt high speed to improve efficiency, the crane with heavy lifting is suitable to choose low speed to reduce driving-power and improve travelling stability and safety.

Working speed is also related to working class and working requirement. The crane with high class, frequent use and high efficiency can adopt fast speed, working mechanism with low class and adjusting purpose can adopt low speed. The crane only used for equipment installation and maintenance can choose low speed. According to practical needs, it can also adopt double speed (high and low speed), dead speed or adjustable speed.

What’s more, working speed is also related to working room. The crane with long travelling distance, high lifting height is suitable for high speed.
