  • APPARATUS FOR MONITORING LOADING OF A LIFT
    Publication number: 20020144862
    Abstract: A load lift comprising a lifter and a linkage on the lifter carrying a load support for movement therewith to different elevations. The linkage is a four-member linkage which includes a first vertical side member carried by the lifter, a second vertical side member carrying the load support, a third member constituting an upper member of the linkage pivotally connected to the first and second members, and a fourth member constituting a lower member of the linkage pivotally connected to the first and second members. An interconnection between the first and second members holds up the second member and load support and is thereby subject to loading on account of the load support and load thereon. Instrumentation senses the loading on the linkage indicative of the load on the load support.
