Weigh Containers on Ground

Weigh Containers on Chassis

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 weighing capacity of 35,000 kg (77,000 lb) and weigh ISO containers of all types and sizes, including high cubes, reefers, flat racks and ISO tanks, from 10 foot to 53 foot.
