BISON's portable container weighing jacks take the hassle out of getting your container weighed. By taking the scales to the container, you save time and money by weighing containers at a time and place that works best for you.

Avoid Weighbridge Costs & Delays

Portable, safe and accurate, C-Jacks remove the costs, delays and potential for errors that come with weighing containers at weighbridges.

Maximise Container Loads

With C-Jacks you can weigh containers in real time, as you load. Maximise the payload and ship with confidence, knowing you are optimising revenue and shipping costs.

No More Overloading

By weighing the container at the pack point, you eliminate the costs and complications of shipping overweight or imbalanced containers.

Trade With Confidence

With OIML certification and legal-for-trade approval in multiple countries, C-Jacks equip you to measure, check and trade bulk liquids, powders and other containerised commodities with absolute assurance.

Weigh Early Weigh Right

Unlike traditional weighing methods, BISON C-Jacks equip you to weigh containers at the loading point, anytime before, during or immediately after the container is loaded. This means:

Guaranteed Compliance

Having an accurate gross weight before the container is transported puts your business in full compliance with the CTU Code, SOLAS VGM and Chain of Responsibility rules. In turn, you are contributing to safety in the logistics chain.

Better asset utilisation

By using inexpensive equipment to weigh containers, you don't need to detain expensive assets such as trucks, weighbridges, cranes and container handling equipment. Ultimately this can result in savings and a return on investment for your business.

More control & independence

Aligning the weighing and loading operation puts you in control of your container weights. Get an accurate container tare before you load. Check the weight as you're loading. And get accurate gross and net container weights as soon as loading is completed. This removes reliance on third parties - such as transporters, weigh stations, ports and forwarders - and avoids the risk of errors, slow communications and delays after the container is dispatched.


Truck scale charges add up to high operating costs over time. Many of our customers get a return on investment from their C-Jacks within months, just from avoiding weigh station fees. Check out this useful calculator to find out how much your business can save on container weighing costs.

Smarter Payload Management

And if your cargo is weight sensitive or subject to strict weight limits during transit, weighing early means you have every opportunity to check and optimise your cargo as you stuff the sea can, maximising the container space, lowering aggregate freight costs and avoiding the risk and cost of being picked up overweight after the doors are sealed and the container ships.
