Akkerman operator‐controlled Haul Units transport spoil from the conveyor to the dirt bucket, along the track in the tunnel to the launch shaft for soil disposal.
Our Haul units are electrically driven, propel forward and reverse, and equipped with regenerative disc brakes.
Haul Units are available in two sizes in standard and extended lengths to complement our family of TBM models and dirt buckets. Two track gauge widths are available for efficient spoil transportation on all pipe jacking projects.
The largest capacity Haul Unit can be configured to trolley tandem dirt buckets on the large‐diameter projects.
Features:
- Haul Unit/Muck Cart systems for 36‐in.+ minimum ID tunnel sizes
- Removable battery pack to keep spare to minimize downtime
- Regenerative motor braking
- Inching control for precise propulsion
- Front and rear lights with flashing blue beacon

Testimonials
Lithos Engineering is focused on providing tunnel design and construction management for underground construction projects across the United States and has worked with many different tunnel contractors on projects of varying sizes and complexity. I am always happy
to see Akkerman equipment on our project sites and I know we can rely on Akkerman products for a high level of performance and reliability.
I had the pleasure of working with Akkerman on one of our projects for which they designed and constructed a project specific hard rock TBM for a curved water conveyance tunnel high in the Rocky Mountains of Colorado. Akkerman not only provided great solutions and technical support for the project but was a pleasure to work with in a collaborative teaming environment that allowed us to not only reduce project risks but reduce construction costs and schedule. During that project, I visited the Akkerman production facility to inspect the TBM under construction; I was extremely impressed with the Akkerman management, staff, and systems for quality control. I look forward to a long future of working with Akkerman and their products on our tunneling projects.
