Model JPA
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.
