Unique load cell installation/ removal without jacking by using the built in cam mechanism. The loading assemblies has a specially designed eccentric shaft. During installation or maintenance, user can easily remove or insert the loadcell from/ into the loading assemblies by rotating this lifting shaft and lift up the load. The user can then adjust the four bolts in the corners of the loading assemblies to secure* the structure and the loadcell is ready to be removed or inserted. The process can be easily done without the help of a jack. The loadcell is secured in the loading assemblies by two round pins, which can also be easily inserted/removed without the help of any tools. *Note: additional security is recommended if the system will stay idle without the loadcells for a prolonged period.
