Straightpoint ATEX Loadshackle available in capacities from 3.25t to 500t 

Straightpoint’s Wireless ATEX 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.



The new Straightpoint ATEX Loadshackle wireless load cell approved to Ex ia II C T4 Ga for use in zone 0,1 & 2 hazardous and intrinsically safe load cell.

Available from stock in capacities 3.25t to 120t and available up to 1,550t, the Straightpoint ATEX Loadshackle wireless shackle load cell is now available ATEX and IECEx approved to Ex ia II T4 Ga for use in zones 0, 1 and 2 hazardous environments (gas and is designed for the on and offshore oil and gas, chemical and other industries with challenging hazardous areas. It is manufactured from Crosby’s industry leading 2130 Carbon and 2140 Alloy Bolt Type Anchor Shackles (3.25te – 120te) and the GN H10 Alloy Bolt Type Anchor Shackle (200te on up)

Each wireless Straightpoint Loadshackle is proof tested, then equipped with a hard-anodised aluminium 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 Straightpoint Loadshackle 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.

Utilising 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.
