HELAC ALTERNATIVE
L30-65-S-RF-180-S1-C-H Rotary Actuator
Alternative rotary actuator for the Helac L30-65-S-RF-180-S1-C-H, a 180-degree, rear-flange (RF) helical actuator in the L30-65 mining class, in the 107 kg weight band. It is listed by Atlas Copco / Epiroc under part number 3128312607 (also written 3128-3126-07) in the supplier cross-reference list. This is the 180-degree rear-flange sibling of the better-documented 360-degree L30-65-RF build.

Questions
Frequently asked questions
What does the L30-65-S-RF-180-S1-C-H replace?+
It is the model code for a Helac helical rotary actuator providing 180° rotation in the 107 kg class. It is listed by Atlas under part number 3128312607. Our alternative is matched to the same rotation, 107 kg class and mounting interface.
What is Atlas Copco / Epiroc part 3128312607?+
Part 3128312607 is recorded against the Helac L30-65-S-RF-180-S1-C-H, the 180-degree rear-flange build of the L30-65 mining actuator, in the 107 kg class. Send the tag from your unit and we confirm the 180-degree rotation, rear-flange mounting and ports before quoting.
Is the L30-65-RF-180 the same as the L30-65-RF-360?+
They share the same L30-65 rear-flange family but are different rotation-angle builds: this unit rotates 180 degrees, while the RF-360 builds (such as Atlas 3128312644) rotate 360 degrees. The angle, end stops and porting differ, so they are not interchangeable; confirm the rotation code on your nameplate before ordering.
Why is the exact HM model and price not shown?+
We confirm the HM model per inquiry after verifying the interface and operating parameters with you. This avoids shipping a part that looks right by model name but differs in mounting or rotation. Price is provided with that confirmed quote.
