Transport, turning, putting down and erecting of loads
- Connection to crane with hangers, crane hook suspensions, attachment points, slinging devices or rope pulleys
- Centre of gravity compensation by electromotive, via spindle or chain driven, hangers or crane hook suspensions
- High flexibility of the crane due to coupling beam
- Force-locking external gripping with one or two parallel gripping arm pairs
- Generation of the clamping force by hydraulic cylinders
- Type and shape depending on the load and the transport task:
Slab/double slab tongs, Block/double block tongs - Picking up the load with load-specific gripping elements such as jaws, gripping tips, rosettes or friction linings.
- Gripping tips and rosettes rotatable for putting down and erecting the load
- Material protection by protective coverings
- Rotation of loads around the vertical axis by electromotive driven slewing gear
- Smooth acceleration/deceleration by frequency converters
- Sensors for detecting the required clamping pressure
- Optional sensors for load weighing, inclined slope, environment detection
- contactor control, SPS or control integrated in crane control
- Low maintenance due to automatic lubrication
- Optical and acoustic signaling of operating states
- Safety against unintentional opening by two-button operation
- Ensuring the clamping force in the event of a power failure by electro-hydraulic safety components
- Own control elements (control panel, radio remote control) or crane control
- Safe maintenance with maintenance platform or storage rack
