The Container Jacks comply with OMIL R76 as required by the Australian Maritime Safety Authority. You can rest assured that by using the Bison Container Jacks you will be able to supply your shipper with a container with a correctly verified weight to send off to its final destination.


For weighing oversize cargo and other large objects, combine BISON C-Jacks to a Connector and a pair of steel beams to weigh bulky objects other than containers.

Attach the Connector to a steel beam or forklift pocket (100 x 150mm Rectangular Hollow Section or RHS) to create a portable, heavy duty beam scale with a weighing capacity of 35,000 kg.Or, bridge the beams with a steel plate to set up an accurate weighing platform, customised for your needs in any location.

Over and above meeting SOLAS guidelines Container Jacks will soon have a certificate of approval for trade use. this means that you will be able to verify the weight of the container for trade use. This is only applicable for when there is a cost charged to any party that is based on the weight of the goods.
