    Abstract: An award includes a representation of at least a portion of a world globe and three human figures in yoga postures imposed on its surface. The three human figures include a figure in a sitting position with legs stretched out and arms raised; a figure supported on its shoulders, curled with its chin near its chest and its legs stretched back over its head, and a figure in a kneeling position with its head bent back. The three dimensional sculpture assembly of a globe and human figures is an iconic and enduring symbol of the “Manitowoc Spirit of Innovation,” It utilizes symbols “???” or “??{dot over (?)}”=Manito in yoga postures representing the Native American origin of the word “Manitowoc” to demonstrate Manitowoc's belief in the value creation business model, such as “Inside Out”, “Co-Creation” and “Outside In”, along with a team spirit to provide a superior customer experience.

  • Patent number: 5297019
    Abstract: An improved control system for operation of a liftcrane having mechanical subsystems powered by a engine and connected thereto by a closed loop hydraulic system with one or more individual closed hydraulic loops. The liftcrane includes controls for outputting signals for operation of the mechanical subsystems and a programmable controller connected and responsive to the controls and connected to the mechanical subsystems. The programmable controller is capable of running a routine for controlling the mechanical subsystems. A first set of sensors is operable to sense the pressure in the closed loop hydraulic system at each of the mechanical subsystems in a first set of mechanical subsystems and provide an output to the programmable controller indicative of the hydraulic pressure sensed.
