The removal of risers and feeders from castings with traditional hand tools is a tough job. Holmatro has developed a new series of hydraulic foundry wedges that are all easy to handle and position. Wedging with these tools reduces the physical exertion and it increases the productivity, without damaging the castings.

The new series of hydraulic foundry wedges is the result from thorough research carried out by Holmatro in the biggest foundries in Germany. During the research the work in practice with a foundry wedge, hung form a balancer, was closely examined. Findings: the operator, standing behind the tool, has the largest possible freedom of movement when the hoses are assembled in the middle, on top of the tool. Such a positioning of the hoses also ensures that the roll-over-point of the tool lies forward. Therefore, the wedge can easily be tipped over and rotated in every direction without the need to reposition the casting first. These results have lead to Holmatro’s new series of hydraulic foundry wedges.

Other distinctive features are the ‘pistol’ control grip, a high operation speed, durable wedge blades and quick blade replacement (in 30 seconds!).
With the introduction of the new generation hydraulic foundry wedges Holmatro is in the lead in terms of ergonomics and quality.
