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
Capitol Tunneling was awarded a Sub-Contract from E.S. Wagner on ODOT Project 277 (18) in Toledo Ohio in 2018 and patterning with Team Akkerman was vital to the project’s success. The installation consisted of 2600 feet of 66″ casing utilizing the Akkerman 540 series 2 TBM, the 5200 Pipe Jacking unit, and a wide range of support equipment. Not only did the equipment outperform our expectations, the technical support went above and beyond from the start. From onsite training at Akkerman’s facilities in Minnesota, to the project site training by expert field technicians, they provided support and expertise from set up to completion. Thank You Team Akkerman for making our project a success and for thoroughly educating our team members while providing world class equipment. Your commitment to excellence allowed us to complete the project the way Capitol Tunneling Inc. expects all project to be completed…On Line…On Grade…and On time
