3.5 Underbody/Axle Scale Load Cell
Model PL9000-22 load cell uses two separate bearing plates, one per end. The load cell is used for underbody
mounts, and in axle scales as a replacement for load cells of other manufacturers. Rated dynamic capacity of the
load cell is 12500 lb (5670 kg). For axle scales, the load cell is rated at 30,000 lb (13600 kg) static capacity. The
load cell assemblies are fastened to bearing plates with a 1"-14 UNF x 2.50" L Grade 8 hex head cap screw. The top
surface of the load cell has three 1"-14UNF bolt holes and two 7/8"-14UNF bolt holes for mounting of brackets or
weighbridge ends. The 7/8" and 1" bolts must all be torqued to 800 lb/ft (1084 Nm), except bolts used for spring
mounts. Check for thread depth and bolt penetration into the cell to ensure the outer top surface bolts in the load
cell ear cannot bottom-out under load. See “Bolt Torque Values” on page 58 for cautions on bolt length for “eared”
load cells.
