Questions
Frequently asked questions
What does the L30-125-M-FT-360-S1-C-H replace?+
It is the model code for a Helac helical rotary actuator providing 360° rotation in the 285.8 kg class. It is listed by Atlas under part number 3128314313. Our alternative is matched to the same rotation, 285.8 kg class and mounting interface.
How do I know this fits my machine?+
The same actuator is recorded on the Simba S7D, Simba H1257. Before quoting we confirm the mounting face, port position and rotation against the tag and a photo of your unit, so the replacement matches your exact build.
Which rigs use Atlas Copco / Epiroc part 3128314313?+
Part number 3128314313 is commonly listed on the Simba S7D and Simba H1257 production-drill rigs, corresponding to the Helac L30-125-M-FT-360-S1-C-H configuration (360-degree rotation, metric BSPP ports, foot mount). Because rigs of the same range can be built with different turning devices, send the part number on your tag or a nameplate photo and we confirm mounting, shaft and ports before quoting.
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.
