Smart Features included in basic die gripper crane
Active Sway Control
Sway Control limits load swing by controlling the acceleration and deceleration of the bridge and trolley, enabling faster load handling and more precise positioning. Active Sway Control automatically eliminates load swing during crane operations. Based on the continual measurement of the angle between the trolley and gripper, it fine tunes the speed commands and stabilizes load movement in trolley and bridge travel including rotational control and skew compensation.
The Sway Control system also provides functions that go far beyond simple sway damping:
- Perfect control of the load oscillation in all driving situations
- Simultaneous motion of hoisting, long and cross travel and slewing gear rotation without any restriction
- Highest precision at maximum driving dynamics due to short internal cycle times
- No overshoot - stop without reversing. Virtually complete elimination of sway at stop
- No residual sway
- Very high target accuracy of less than ± 10 mm at the load
- Very high load rotational angle control accuracy of less than ± 0,2 deg. at the load
- Automatic mode at any lifting height
- Automatic circumnavigation of restricted areas
Hook Centering
The Hook Centering feature eliminates side pull and the resulting load swing. When the die gripper is coupled, Hook Centering ensures that the load can only be lifted when it is directly vertical under the trolley. The vertical angle as well as the rotation angle are determined by a camera-reflector system and compensated by the control system.
Target Positioning - optional
Target positioning moves the load along a pre-determined route from an initial position to a selected target position. The operator selects the target position via the radio control, presses a button, holds it down and the crane moves to that position. This reduces work cycle times and the risk of human error in repetitive operations.
Protected Areas - optional
Possible obstacles, such as the press, try-out press, offices or work areas, are taken into account when determining the transport routes from the die storage to the press as a bypass area, executed in safe performance level d.
