The Complete Shipping Container Weighing System

BISON's portable container weighing jacks take the hassle out of weighing containers. 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. BISON C-Jacks send container data through the VGM App, directly to your computer.

WEIGH BULK CARGO as you load

C-Jacks enable you to monitor bulk cargo weight as you load, simplifying the weighing process and saving you time and money.


C-Jacks remove the costs, delays and potential for errors that come with weighing containers on truck scales.


With C-Jacks you can weigh containers in real time, as you load. Maximise payloads, revenue and freight costs with every shipment.


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


C-Jacks equip you to measure, check and trade bulk liquids, powders and other commodities with absolute assurance. C-Jacks are OIML certified and legal-for-trade approved in 40 countries. Ideal for SOLAS VGM compliance.

More Reasons to Choose C-Jacks

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:

No more truck scale charges

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. Find out how much your business could save in weighing fees with our free weighing calculator. 

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.

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 container, maximising the container space, lowering freight cost and avoiding the risk of being picked up overweight after the container ships.
