Beschreibung
Zusammenfassung:	The invention discloses a speed classification system for crane balance weight oil cylinder synchronous movement and a crane. The speed classification system for adjusting oil cylinder synchronous movement comprises a first reversing valve, a second reversing valve, a first oil port, a second oil port, a flow dividing and collecting valve and damping parts. The flow dividing and collecting valve comprises a first flow dividing port, a second flow dividing port and a flow collecting port, the flow collecting port communicates with the first oil port, the first flow dividing port communicates with a first connector of the first reversing valve, a second connector of the first reversing valve communicates with a rodless cavity of a first oil cylinder, and a third connector of the first reversing valve passes through the corresponding damping part and then communicates with the rodless cavity of the first oil cylinder. The second flow dividing port communicates with a first connector of the second reversing valve
