A working cycle of a crane includes: the picking device lifts the object from the picking place, then moves horizontally to the designated place to lower the object, and then performs reverse movement to return the picking device to its original position for the next cycle. Usually, a lifting mechanism is composed of a lifting mechanism (to move the object up and down), a running mechanism (to move the lifting machinery), a variable amplitude mechanism and a slewing mechanism (to move the object horizontally), plus a metal mechanism, a power device, an operating control and necessary auxiliary devices. A multi-action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range is also called a crane. It is mainly used to lift finished objects, and can also lift bulk materials and liquid materials after being equipped with appropriate lifting equipment. The working characteristic of a crane is intermittent movement, that is, the corresponding mechanisms for picking, moving, unloading and other actions work alternately in a working cycle. Each mechanism is often in a working state of starting, braking and running in forward and reverse directions.
