ZOOM ASSY RIGHT

326 716 08D ZOOM ASSY RIGHT Functioning as the main carriage for the rock drill, this assembly slides along the feed beam, transmitting feed pressure to the drill string. Its rigid construction is essential for maintaining the correct drilling axis from the moment the bit touches the rock. Proper alignment prevents unnecessary stress on the drifter and drill steel.

Wear and tear on this assembly can directly impact drilling accuracy and overall reliability. When the guide bars or contact pads wear down, the drifter can develop excessive play, causing hole deviation and increasing the risk of getting the drill steel stuck. This misalignment also accelerates wear on the drifter's front head and shank adapter.

Look for visible wobble or looseness of the drifter on the feed as a primary sign of wear. During routine checks, inspect the assembly for cracks and measure the wear on its slide surfaces. Keeping mounting bolts tight and replacing the assembly when wear limits are reached prevents costly collateral damage.
