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.

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.
