The Crane used to transport, organize, move some sand from one place to other place was paired with Yaskawa inverters G7. Previous systems used to drive the motor traverse (x-axis), travel (y-axis), and hoist (z-axis) was Direct On Line (DOL). However, since the Energy Saving taken into consideration, then the system was migrated to the inverter system. Inverter Yaskawa G7 is able handle a constant speed on the hoisting. Even for the more advanced types are able to utilize regenerative energy generated at the time of lifting down the hoist. Once paired inverter, then the crane has smooth movement and energy efficient.
