3128078548, 3128 0785 48 HOLDER ATLAS COPCO

If your drilling rig’s moving assemblies are only as reliable as the way its hoses, covers, and protection profiles are guided, then a small component like a holder becomes a big deal. The 3128078548, 3128 0785 48 HOLDER ATLAS COPCO is a right-side holder/support element used on Atlas Copco / Epiroc drilling equipment, designed to keep protective components aligned, stable, and protected from vibration-driven wear.

In the field, misalignment is expensive: rubbing hoses, chafing covers, premature cracking of protective profiles, and an increasing maintenance cycle that keeps the machine out of production. The 3128078548 HOLDER ATLAS COPCO is built to reduce those risks by providing a rigid mounting base and a wear/contact surface (the yellow pad visible in the product images) that helps manage friction and positioning in an area exposed to dust, shock, and constant motion.

This page explains what the part does, why its design matters, where it’s commonly used, how to recognize failure, and how to install it properly, so you can keep uptime high and protect the systems around it.

What the 3128 0785 48 HOLDER ATLAS COPCO does on a drill rig

On many surface and underground drilling rigs, multiple subsystems move together, feed systems, cable/hose management, protective covers, and profile-guided components. Over time, vibration, impact pulses, and micro-movements cause contact points to wear. A holder/support part like the 3128 0785 48 HOLDER ATLAS COPCO is typically installed to:

• Support and position a cover, guard, or profile assembly on the rig

• Provide a stable “reference” mounting surface so adjoining parts stay aligned

• Reduce friction damage where a cover/profile contacts another surface (via the wear pad)

• Help prevent loosening and deformation by using slotted mounting holes for adjustment

Aftermarket listings commonly describe this component as a right-side holder/support for Atlas Copco / Epiroc equipment.

Even if the holder itself looks “simple,” it acts like a protective interface: it helps prevent collateral damage to hoses, protective profiles, and surrounding assemblies, damage that can lead to leaks, electrical faults, or sudden downtime.

Visual design cues from the product images

From the provided images, this part appears to be an aluminum (or light-alloy) holder block with:

• Two elongated slotted mounting holes (for alignment/positioning during installation)

• A mounted yellow wear strip/pad (contact surface to reduce abrasion and manage friction)

• Fastener/pin points securing the wear pad to the holder body

This design is consistent with holder/support components used on drilling rigs to guide or support protective profile assemblies.

Part numbers and search formats you should use

To capture all the ways buyers search, use both number styles throughout your page:

• 3128078548 HOLDER ATLAS COPCO

• 3128 0785 48 HOLDER ATLAS COPCO

These two formats help your listing rank whether the customer searches with spaces or without them.

Common applications and compatible equipment

Online parts listings associate the 3128078548, 3128 0785 48 HOLDER ATLAS COPCO with Atlas Copco / Epiroc drilling rigs and related equipment families. For example:

• The part is presented as a holder/support used on Epiroc drill rig assemblies.

• Some listings reference compatibility/applications including Boomer and Boltec series and surface rig lines, depending on configuration.

• A ROC D55 parts context also appears in publicly visible parts lists that include this part number.

• A product listing also references applications such as Epiroc Boltec 235, Boomer 104, and Roc D55.

Important compatibility note

Rigs often have multiple revisions by serial range, build year, and option package. So treat model lists as guidance, your final confirmation should be made by:

• Your machine’s serial number

• The parts book / exploded diagram for the assembly

• Cross-checking the replaced part number stamped/marked on the old component

If you want, you can paste the rig model + serial range (or assembly diagram screenshot) and I’ll help you confirm placement and related parts (profiles, fasteners, pads).

Why this holder matters more than most buyers think

When a holder is worn or misaligned, the damage rarely stays “local.” You start seeing secondary problems:

• Protective covers vibrating loose or drifting out of position

• Wear lines on profiles and guides that should last far longer

• Hose/cable routing that changes subtly, leading to rubbing and pinching

• Fasteners that keep backing out because the surface is no longer stable

Replacing the 3128 0785 48 HOLDER ATLAS COPCO on time helps protect higher-value components around it, especially in harsh drilling conditions where dust, water, and vibration accelerate wear.

Material and engineering intent

Most holder/support parts in this category are engineered with two goals:

1. Rigid positioning
   The base must hold alignment under vibration and repeated shock loads.

2. Controlled contact
   The contact surface should be sacrificial and replaceable, so it wears instead of the more expensive surrounding parts.

The yellow strip seen on this 3128078548 HOLDER ATLAS COPCO is consistent with a wear pad concept, helping reduce metal-to-metal contact and smoothing motion where a profile/cover meets the holder.

Symptoms that indicate you should replace the holder

Replace the 3128 0785 48 HOLDER ATLAS COPCO if you see any of the following:

• The wear pad surface is deeply grooved, chipped, or uneven

• Covers/profiles no longer sit square and begin rubbing on edges

• You can move the holder by hand (loose mounting or elongated wear)

• Fasteners keep loosening even with correct torque and thread-lock practices

• New protective profiles wear prematurely after installation

A good habit is to inspect this area during routine maintenance, especially if the rig is used in abrasive rock dust or high-vibration drilling cycles.

Installation guide for 3128078548 HOLDER ATLAS COPCO

Below is a practical installation workflow that fits most drill-rig holder/support parts of this type.

Tools typically needed

• Correct socket/hex set for the mounting fasteners

• Torque wrench (recommended)

• Threadlocker (medium strength, if specified by your maintenance standard)

• Cleaning spray and lint-free cloth

• Straight edge or alignment reference (optional but helpful)

Step-by-step installation

1. Lock out and secure the machine
   Ensure the rig is powered down and secured according to site safety procedure.

2. Document the original position
   Take a quick photo of the holder orientation and the alignment of the attached cover/profile. Those slotted holes exist for a reason, your current alignment is your reference.

3. Remove the old holder
   Loosen the mounting bolts and remove the old 3128078548 HOLDER ATLAS COPCO. If the part is seized due to dust/corrosion, clean and carefully free it without damaging the mounting surface.

4. Inspect the mounting surface
   Clean the base area. Look for burrs, dents, or misalignment that may have caused the old holder to wear unevenly.

5. Dry-fit the new holder
   Position the 3128 0785 48 HOLDER ATLAS COPCO and hand-tighten bolts. Keep it adjustable until alignment is confirmed.

6. Align the cover/profile contact
   Set the holder so the wear pad contacts the intended surface evenly. Avoid edge-loading the pad, which accelerates wear.

7. Torque fasteners to spec
   Use the correct torque specs for your assembly. If your standard procedure requires threadlocker, apply it appropriately.

8. Functional check
   Slowly cycle the moving assembly (where safe and possible). Verify there’s no rubbing, binding, or unexpected noise.

9. Re-check after initial operation
   After a short operating period, re-check fasteners and alignment, especially in high-vibration areas.

Maintenance best practices to extend service life

To get the most life out of the 3128078548, 3128 0785 48 HOLDER ATLAS COPCO:
