Electric Muck Haul Systems - Akkerman


Akkerman Inc.

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.

  • 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
