Vektorokran

Vektorokran is a term used in engineering literature to describe a crane system whose motion of the load is planned and controlled using vector-based representations in multiple dimensions. The concept emphasizes treating the crane’s reach, lift, and orientation as coordinated vectors rather than relying solely on independent axis movements. The term is most commonly encountered in Hungarian technical contexts, where it functions as a descriptive name for advanced, multi-axis crane configurations.

A typical vektorokran combines a hoist with a movable trolley and at least two or more actuated drives, which may include a gantry bridge, a jib, or Cartesian-style axes. The control system uses vector arithmetic to determine the optimal path for the load, taking into account position, velocity, acceleration, and load orientation. In operation, the system tracks the end-effector (the load) with sensors and computes the necessary actuator commands to follow the planned vector trajectory while compensating for disturbances such as wind, load swing, or dynamic payload changes.

Control strategies often involve vector-based path planning, state estimation from sensor fusion, and advanced controllers such as model predictive control or adaptive PID schemes. Safety features typically include load limit monitoring, collision avoidance, and emergency stop mechanisms. The design aims to improve precision, smoothness, and efficiency of heavy-lift tasks, particularly in environments where complex load paths and orientations must be maintained.

Applications include construction, shipyards, industrial automation, and film or theater production where controlled, multi-axis lifting and positioning are required. Challenges include higher system complexity, cost, and the need for sophisticated maintenance and operator training.
