Normally closed design with spring clamping and hydraulic cylinder-driven release.

Corrosion-resistant design.

Equipped with a release limit switch for interlocking protection with the crane's traveling mechanism.  

The clamp body features a floating structure: horizontal floating distance of ±20mm and vertical floating distance of ±10mm.  

The main unit and hydraulic station generally use a combined structure (if separation is needed, please specify at the time of ordering).

Ambient temperature : 0℃-40℃。

Hydraulic station drive power supply : three-phase AC380V, 50HZ(if other voltages are required, specify in advance when ordering).

Hydraulic station control power supply : AC220V、50HZ。

Limit switching power supply : AC125V-250V。

Applicable working mode : intermittent, short time effect lower frequency.
