ABSTRACT:
A materials handling vehicle, such as a turret stockpicker, includes a telescoping mast comprising inner and outer sections. The staging of these sections, and the stopping of the platform assembly is smoothed by monitoring the actual height of the platform and restricting the speed of the platform as it approaches these transition points. The height of these transition points are stored in a digital memory. The platofrm speed is normally determined by a control handle, but as the platform reaches a transition point, the maximum speed of the platform is restricted by a micro-computer which controls a servo controlled hydraulic valve and the hydraulic pump motor supplying hydraulic fluid to the platform lifting cylinders. The maximum rate of platform movement after a transition is returned to the control of the operator.
