Installing concrete cofferdams

Both mechanical and hydraulic cofferdam grippers are available.

Mechanical cofferdam grippers have a maximum lifting capacity (SWL) of 3000 kg and a dead weight of 34 kg.
The great advantage of the mechanical cofferdam gripper is that it clamps under the weight of the cofferdam. A hydraulic connection is therefore superfluous. The maximum gripping depth is 300 mm. The gripper has a width of 200 mm. If a greater gripping depth is required, we recommend the hydraulic cofferdam gripper.

The hydraulic cofferdam gripper has a maximum lifting capacity (SWL) of 10000 kg and a dead weight of 500 kg. Deviating lifting capacities are also possible. Thanks to the hydraulic power supply, this cofferdam gripper clamps the whole time. The great advantage of the hydraulic cofferdam gripper is its impressive lifting capacity. In addition, the gripping depth of this gripper is 750 mm. The gripper has a width of 800 mm. This surface prevents cracking at the clamping point.
