The operation speed of electric gantry crane is related to the quantity of motors and operating principles.
Single speed means the electric gantry crane has only one speed.
Two speed means that the electric gantry cranes have two operating speeds, which are equipped with two motors of different speeds. With two motors, one produces a faster speed, one is slower speed.
VVVF speed means that the motor speed can be changed by adjusting the power supply frequency, the motor can produce different operating speeds.
Compared with single speed gantry crane and double speed gantry cranes, VVVF speed electric gantry crane has the characteristics of stable starting, large speed range, small current and high precision, which is the future trend of crane industrial. In contrast, the price of VVVF speed electric gantry crane will be higher.
