Straightpoint Wireless Low Headroom Load Cell

Durham Lifting’s Straightpoint Low Headroom Load Cell is now available as a wireless product the Straightpoint range of Low Headroom Links are designed to provide accurate measurement of loads in the most challenging applications where headroom restrictions are a major factor. Constructed from high strength alloy steel and exposed to an array of testing during development, this impressive range of load cells is designed to work with industry standard shackles from manufacturers such as Crosby and Van Beest. Applications include weighing, lifting, force measurement and load monitoring of structures such as lighting trusses, hoist mountings and fly line tensioning.


Product Description

The unique low headroom design combines the ability to lift loads with capacities up to 30t and features industry leading wireless technology and range of 700m or 2300ft. The versatile WDB is supplied with an update rate of 3 Hz and can be easily configured to run at industry leading speeds of up to 200 Hz. Data is transmitted wirelessly utilising the latest in IEEE 802.15.4 (2.4 GHz) technology providing safe, high integrity, error free transmission of both static weight and dynamic loads to Straightpoint’s SW-HHP wireless handheld display or up to 100 WDB load cells may be connected to our SW-MWLC multi load cell data logging software. Environmentally sealed in an aerospace aluminium enclosure and sealed to IP67 or NEMA 6 the WDB utilises easily sourced AA alkaline batteries and 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.
