Used for bending and straightening steel reinforcing bars. Two types of test can be performed:
The machine consists essentially of a hydraulic jack with cylindrical mandrel-stem, mounted horizontally within a strong steel frame which also carry two fixed reaction rollers. Two 50 and 100 mm dia. rollers are supplied with the machine. Mandrels and mandrel holders have to be ordered separately. Mandrels larger than 96 mm dia. do not need mandrel holders because they fit directly onto the stem.
ASTM specifications require 100 mm dia. rollers only and the bent up to 90°.
