HANDLE PLATE

551 663 59 HOOK PLATE Serving as a critical structural link, this plate holds components at a specific, engineered angle. It is often found in the feed assembly, where it correctly orients the drifter cradle relative to the feed beam. This precise alignment is fundamental for preventing drill steel deviation and ensuring drilling forces are transmitted efficiently along the intended axis.

A damaged or bent HANDLE PLATE directly compromises drilling accuracy and can lead to increased operational costs. For example, if the plate responsible for feed alignment is deformed, the drill string will not be parallel to the feed, causing excessive wear on guide components and potentially breaking the drill steel. Over time, the stress from this misalignment can cause fatigue cracks in the plate or surrounding structures.

Visually inspect the plate for any cracks or bending during regular service, paying close attention to the areas around mounting holes. Check that all fastening bolts are secure. If any deformation or cracking is discovered, the plate should be replaced to restore the machine's original geometry and prevent further damage.
