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 400t (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/328ft.
Each WLS is proof tested, then equipped with a hard-anodised aluminium electronics enclosure. Contained within this aluminium 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 is supplied with an update rate of 3Hz and can be easily configured to run at industry-leading speeds of up to 200Hz if required for dynamic load measurement projects.
Utilising easily sourced AA alkaline batteries the WLS features advanced circuitry designed to protect the unit from damage associated with incorrectly installed batteries. This advanced circuitry extends battery life and the use of easily sourced alkaline batteries eliminates 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 is also available including signal boosters, LED wireless scoreboards and base stations with analogue (4-20mA, 0-10v, 0-5v) or digital (RS232/485, Modbus RTU, and ASCII) outputs.

SW-OAM Wireless overload alarm module The SW-OAM is a wireless relay module featuring audio and visual warning indicators.
The alarm can be triggered based on the set alarm level of individual loadcells.
Units can be paired with a maximum of four loadcells, the alarm will be triggered if any one of the loadcells exceeds its set alarm level.
The SW-OAM is ideal as a Wireless Overload Detection System.
