Strainstall's Container Weight System (CWS)™ seamlessly integrates load monitoring technology onto existing container handling equipment, with no operational impact to ports and terminals.
CWS™, specifically developed to meet the International Maritime Organisation's amendments to SOLAS safety guidelines, delivers accurate weight verification data in real-time, as part of a ports regular lifting cycle.
Fully configurable to your specific spreader based cargo handling equipment, CWS™ seamlessly integrates into existing terminal operating systems (TOS), giving a simple and automated process for producing verified gross mass (VGM) for SOLAS compliance.

The award winning Container Weight System™
Port Technology International interviews Strainstall's managing director, Simon Everett, on the SOLAS VGM rules that ports and terminals need to know
“We assessed a number of different options to be able to offer a container weighing service to our customers and selected Strainstall’s system because it doesn’t require any changes to our port operating procedures and is quick to install. The trials demonstrated an accuracy above our expectations.”
Nick Loader, chief executive officer, DP World Southampton
Fully compatible container weighing solution
Strainstall’s CWS™ is designed to be retrofitted to existing container handling equipment with no modification required enabling quick and easy installation in about an hour. Working closely with original equipment manufacturers (OEMs) CWS™ is fully adaptable to suit all the major crane and spreader manufacturers’ equipment.
The system can be retrofitted into the spreader headblock or at the twistlock making it a permanent feature of the container handling equipment with minimal wear. Alternatively, the twistlocks themselves can be replaced if 20ft twinlift spreaders are used.
