“We have no time restrictions to obtain the VGM.”

We often have last minute bookings that have a 12-noon pickup and cut off at 3 pm. With the Conweigh system, … we just take the container via our yard, weigh it and go. The VGM being emailed through means we don’t have to chase up weigh slips from drivers.

What Customers Say


High-volume cargo and container weighing

One platform for any heavy weighing need

Easily assemble an onsite weighing platform under half an hour using a standard flat rack, platform container, or even open-side containers and the conWEIGHr weighing pedestals.

As soon as cargo, container, or machinery is lowered on the Mobile Deck, the conWEIGHr pedestals send weight data to the Conweigh mobile app which creates Method 1 or Method 2 VGM certificates and Container Weight Declarations (CWD) within 1 minute.
