In semi-automatic operation, the operator is always present on the crane and controls the process.
It is useful in storage spaces or production areas where the work process requires repeated movements of the crane to one or more fixed positions, lifting and lowering the load when different grippers, vacuum or magnetic beam are used…
With automation, the crane is always moved exactly to the same position, thus increasing the accuracy and speed of operation, at the same time relieving the lift operator.
To increase safety, avoidance zones may also be integrated – areas where the crane is not allowed to enter, may operate at reduced speed or may enter only if additional criteria are met (eg. position of hook, load conditions, …)
