DHL-SF Hydraulic clamp | Tunnel construction
The DHL-SF hydraulic clamps are primarily used when space is limited at height. The segments are lifted positively. In contrast to the DML tongs, the legs of this machine are adjusted hydraulically. This design eliminates the mechanical closing and opening unit, which benefits the overall height.
DHL-SF mode of operation:
The clamps are opened and closed hydraulically, enabling controlled closing of the clamps in any position.
The DHL-SF clamps can be equipped with adjustable hold-down devices. These can be adjusted either mechanically using an insertable pin, hydraulically or electrically to set the number of segments to be lifted.
Another option is to install a rotating unit to rotate the segments by 90° if, for example, the segment bearing is not aligned in the direction of further transportation.
The DHL-SF clamps can be ordered in the mains voltage version as well as in the battery-powered version to meet any requirements.
