Tongs, hydraulical

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
