The Model JPA is a vertical lifting clamp capable of turning a single plate or member from horizontal to vertical to horizontal through a 180 degree arc. This clamp also has a push-button lock as an additional safety feature, which prevents the lever from being opened accidentally, for example when turning loads. Each clamp is given a RFID transponder as standard, for simplified inspection and documentation. Permits side loading of lifting shackle to 90 degrees by derating of clamp’s rated capacity. Refer to Figure 1 for derated capacities. Model JPA incorporates a pivoting shackle that permits side loading of the lifting shackle at 100 percent of rated capacity from vertical to 30 degrees, 75 percent of rated capacity between 30 and 45 degrees and 50 percent of rated capacity between 45 and 90 degrees.
