Crosby™ cabled
load shackle
The LCM range of Shackle Load Cells is designed for lifting and weighing in rugged or harsh environments. The shackle pins are forged from high tensile carbon steel and are machined to an exacting specification. The basic shackle uses the Crosby G2130 (1-25tonne) and G2140 (40-400tonne) series. This range of load cells is Proof Loaded to 150% of the normal rated load.
The SHK-B series are available in a range from 1 tonne to 400 tonne. The integral cable is normally enclosed in an armoured rubber hydraulic hose to give physical and environmental protection. The SHK-B is internally gauged and the whole instrumented area is sealed to IP67, to protect it in service.
They are simple to install and are available in standard shackle sizes. As an option, a rotating bobbin can be supplied, to centralise the load and to minimise any point-load effects when the shackle is placed under load. We are always pleased to discuss any special requirements that can be accommodated. The SHK-B series can be supplied on it's own or combined with our extensive range of instrumentation to provide a complete load monitoring system.

TELSHACK-B Wireless Telemetry Crosby Bow
Shackle Load Cell
The TELSHACK-B range of wireless telemetry shackle load cells are manufactured using the Crosby G2130 (12-25tonne) and G2140 (40-400tonne). Versions are also available using the popular GreenPin™ range of shackles. The built in wireless radio telemetry electronics operates on the 2.4GHz license free frequency.
The telemetry housing is manufactured from stainless steel, offering a robust solution. Located in the housing are two AAA NiMh batteries, which can be accessed by removing the telemetry housing cover. No tools are required, making it easy to do on site. The batteries can be recharged using the universal charger supplied. In emergencies (when you do not have time to re-charge the batteries), standard alkaline batteries can also be used. There is an external sealed aerial, which can be rotated to offer the best signal polarity and hence the best transmission range, making it more versatile for different applications.
The TELSHACK-B is supplied as standard with a handheld battery powered display, or alternatively, for multi-shackle applications, a single display can address up to 12 shackles for individual monitoring, or for summation/balancing applications. LCM Systems can also supply more complex wireless telemetry systems. For further information on what we can offer, please contact our Technical Department, with details of your application requirements.
