Abstract
Hydraulically operated roll grooving apparatus comprises vertically oriented idler and backup grooving rolls each rotatable about a corresponding roll axis, a fluid actuator for displacing the idler roll toward the backup roll, a manually operated pump for supplying fluid under pressure to the fluid actuator, and a stabilizer for stabilizing a pipe being roll grooved. The pump and stabilizer are mounted on the same side of the apparatus with respect to the roll axes, and the pump has a vertically oriented major dimension and a pump operating lever including a removable handle.
