Weigh Containers on Ground

Weigh Containers on Chassis

"Weighing could not be easier! I really mean this. Even a 10-year old could do this with ease.”

- Tommi Remsu - Logistics Manager, PP Logistiikka Oy

How do C-Jacks work?

  • C-Jacks comprise four portable scales, which attach to the corner castings of any ISO container.
  • Using hydraulic bottle jacks, the container is safely lifted just clear of the ground or chassis.
  • The load at each corner is sent wirelessly to a central indicator, and to the BISON VGM App, giving you a highly accurate gross container weight.
  • C-Jacks have a 35,000 kg (77,000 lb) weighing capacity 
  • C-Jacks can handle ISO containers of all types and sizes, including high cubes, reefers, flat racks and ISO tanks.
