Lifting & weighing

A Range of shackle load cells for harsh Environments

LCM Systems has introduced an innovative range of shackle load cells designed specifically for lifting and weighing applications in harsh or rugged environments. Ideal for use in applications such as under-hook hoist and crane weighing, cable tension monitoring and crane load safety monitoring, the sensors are available in either cabled or wireless telemetry versions.

Ever mindful of customers’ needs and preferences, they can provide the cabled versions with Crosby shackles as standard or as an option with Greenpin shackles. Safety is paramount for the demanding applications in which these shackle load cells are used and the use of high-quality shackles is essential to comply with safety standards and regulations as well as to maintain integrity.

The SHK-D cabled, shackle load cells use the Crosby G2150 and are available in a range from 1 tonne to 35 tonne, while the SHK-B cabled series has a rated load up to 400 tonne, using either the Crosby G2130 or G2140. All shackle pins are forged from high tensile carbon steel and proof loaded to 150% of the normal rated load. The standard product is sealed to IP66 to protect against harsh weather conditions. All load cells in the series are easy to install and can be supplied with a range of instrumentation for a complete load monitoring system.

For engineers wanting a wireless, telemetry option, the TELSHACK range uses integral wireless telemetry electronics operating on the 2.4GHz license-free frequency. Two ranges are offered: TELSHACK-D can be used from 12 tonne to 35 tonne, while the TELSHACK-B can be used for applications up to 400 tonne. Both ranges can be supplied with either Crosby or Greenpinshackles and experienced design engineers at the company can provide expert advice on the correct shackle for each application.

One of the main features of the TELSHACK ranges is that the housing is supplied with a built-in rechargeable battery. This means that they can be removed from the shackle for charging, while the shackle itself remains in place. A handheld battery powered display is supplied as standard with the option of a single display that can monitor up to 12 shackles when the load cells are used in a multi-shackle configuration, either individually or for summation/balancing applications.

LCM Systems’ standard range of shackle load cells can provide an ideal and safe solution for many applications. However, for more complex requirements their Technical Department will work closely with application engineers to provide customised and workable systems for even the most complex applications.
