SHOP BY SERIES

Browse actuators by Helac series

If you already know the series, jump to the dedicated page for specifications, available models, and inquiry options.

Before ordering, double-check the machine model, mounting flange, shaft type, and rotation angle. These four details prevent mismatches when the same OEM part number is shared across multiple drill or bolting rigs.

HOW TO ORDER

4-step confirmation before ordering

01

Check the OEM part number

Compare the Atlas Copco / Epiroc or Sandvik part number from your parts book or the actuator tag with the reference above.

02

Confirm the machine model and mounting flange

Verify the rig model and whether the actuator is mounted on the boom, feed, or rotation unit so the interface matches.

03

Confirm rotation angle and ports

Check the required swing angle, shaft type, and valve / port arrangement against the model code.

04

Send the RFQ

Use the form below or email us the model code, OEM number, and machine details. We confirm the replacement before quoting.

REQUEST A QUOTE

Send your mining drill rig actuator details

Send the Helac model code or OEM part number, the machine model, and photos of the tag and mounting face. We verify the match and quote the correct replacement before you order.

Or email directly: hm@hmhydraulics.com

QUESTIONS

Frequently asked questions

Can I find a replacement from an OEM part number alone?+

Yes, in most cases. A part number such as 3128309281 or 76350015 maps back to a specific Helac-compatible actuator. Send the number and we verify the machine application before confirming the replacement.

Why does one part number fit several machine models?+

Atlas Copco / Epiroc and Sandvik often use the same rotary actuator across multiple rigs within the same platform family — for example Boltec 235 variants share the same rotation unit.

What is the difference between the M and E suffix in the model code?+

They typically refer to mounting or shaft variants that share the same gear set. The exact meaning depends on the series; send the full code and we confirm which variant you need.

Are these original Atlas Copco, Epiroc, or Sandvik actuators?+

No. HM Hydraulics supplies independent replacement actuators that match the original mounting interface and performance data. Brand names are used for identification only.

What if the actuator tag is missing or unreadable?+

Send us the machine model, serial number, and photos of the mounting face and shaft. We can identify the correct replacement from physical dimensions and the parts book.
