MTBM Increase Kits
All Akkerman MTBMs can be factory configured with an increase kit to expand their excavation diameter and further your investment’s versatility. Sometimes called skinning or upsizing, the process involves bolting a custom‐manufactured, fitted steel cylinder onto the exterior of the MTBM to enhance the range of diameters where the machine can be utilized.
Please discuss your project needs with our knowledgeable sales staff to determine your MTBM’s increase kit’s diameter and capacity requirements.
FEATURES:
- Add versatility to existing MTBM products.
- Bolt‑on or weld‑on kits available.
- Typical upsize kits increase diameter by 8–12 in over the base MTBM size; custom kits available.
- Belly‑pan kits can be added for enhanced performance in hard ground.
- Change cutterhead type using an increase kit.
- Adjust pipe and thrust adapters to accommodate jacking pipe.
Testimonials
Akkerman has proven to be the “go-to” manufacturer of American Made TBM’s, GBM’s, and pipejacking systems. This is not just based on the 13+ years I’ve been doing business with them, but the nearly 40-years of successful partnering between Pacific Boring and Akkerman, a relationship I look forward to continuing.
