Straightpoint’s Wireless Loadshackle (WLS) provides the perfect solution to limited headroom or super heavy-lift projects. Available from stock in capacities from 3.25t to 500t (up to 3000t available POA), the WLS is constructed using industry-leading shackles from Crosby.

       Two versions of the WLS are available:

  •  Long-range 2.4Ghz version, providing industry-leading
    wireless range of 1000m or 3280ft to SP’s SW-HHP handheld
    or software options.
  •  Bluetooth output and can be connected to any smartphone
    running our free HHP app on iOS or Android, at ranges up to
    100m or 328ft.


Each WLS is proof tested, then equipped with a hard-anodized aluminum electronics enclosure. Contained within this enclosure is an internal chassis providing IP67 or NEMA6 environmental protection, even with the battery cover plate missing. Featuring industry-leading wireless technology, the WLS can maintain an update rate of 3Hz. It can be easily configured to run at industry-leading speeds of up to 200Hz if required for dynamic load measurement projects. Utilizing easily sourced AA alkaline batteries, the WLS features advanced circuitry, designed to protect the unit from damage associated with incorrectly installed batteries. This circuitry extends battery life, and the use of easily sourced alkaline batteries, eliminating issues associated with rechargeable battery pack charging, failure, and replacement. The WLS may also be used with Straightpoint’s SW-PTP software package, allowing the operator to perform load tests at a safe distance and generate real-time test certificates on-site. A full array of wireless accessories are also available including a wireless scoreboard, overload alarm, and base station with analog (4-20mA) or 2 relays or RS485 ASCII outputs.
