CWS™ reach stacker configuration

Utilising highly accurate load pins, the reachstacker CWS™ configuration offers the most robust and cost-effective means of container weight measurement.

The CWS™ load pin solution for reachstacker container handling equipment has been designed for easy maintenance on site, without the need for external technical support.

As an onboard weighing system CWS™ also provides container snag detection and its centre of gravity (COG), helping to ensure operator safety and the safety of container stowage and transportation.Two or four load pin CWS™ reachstacker systems have no consumable parts, ensuring low operational and maintenance costs.

CWS™ is available as a retrofitted system installed onto existing container handling equipment, and as an available option with any new Kalmar container handling reach stackers.

New or retrofit solution

James Fisher Strainstall’s close working agreement with Kalmar means CWS™ is installed on the production line as an option for ports and terminals ordering new reachstacker container handling equipment.

CWS™ can also be easily retrofitted to existing container handling equipment, to help reduce costs. No modification is required, enabling quick and easy installation. CWS™ also has no consumable parts with minimal wear, helping to reduce operational and maintenance costs.

Commissioning, training and in-service support

James Fisher Strainstall’s NMO type approval means the company is fully certified to provide installation, commissioning and carry in-service system verifications in accordance with the type approval requirements. Each system must be initially verified upon installation and then periodically checked and verified for its in-service accuracy performance.

OEM compatibility

Working closely with original equipment manufacturers (OEMs), CWS™ is fully adaptable to suit all the major reachstacker manufacturers’ equipment with no modification required enabling quick and easy installation. The system can be fitted or retrofitted into the reach stacker headblock making it a permanent feature of the container handling equipment with minimal wear.

Kalmar, one of the leading cargo handling equipment manufacturers, now offers James Fisher Strainstall’s CWS™ system on its reachstackers during production of the container handling vehicles.

OEM support

James Fisher Strainstall is also able to provide training for OEM engineers to enable them to undertake installation and verification routines in accordance with NMO requirements, as part of its certification.
