Abstract
A fork assembly (4) for storage/retrieval machine of high convey efficiency comprises: a rotating table (41); an extension arm (43) provided on the rotating table (41) and capable of conducting stretching motion; a driver unit (42) configured for driving the extension arm (43) to conduct the stretching motion; a control system (100) configured for controlling an operation of the driver unit (42); a position sensor (46) for the breakpoint which is connected to the control system (100) and configured for determining whether the extension arm (43) performs the stretching motion up to the breakpoint (9), and the breakpoint (9) is located between a maximum distance point (10) and a minimum distance point (8) to which the extension arm (43) extends.
