Zusammenfassung:	VOLUME SYNCHRONIZER FOR TUBULAR HANDLING TOOLS A control system (100) comprises a tubular handling tool (60) and a volume synchronizer (80). The tubular handling tool (60) has a plurality of piston cylinders (61) and a plurality of slips (66) configured to engage a tubular string. The volume synchronizer (80) comprises a first piston cylinder (87) having a piston (66) connected to a first rod member (86), a plate member (84) connected to the first rod member (86), and a plurality of second piston cylinders (81), each having a piston (85) connected to the plate member (84) by a plurality of second rod members (89). Pressurized fluid supplied to the first piston cylinder (87A) moves the plate member (84) to move each of the pistons (85) in the second piston cylinders (81), thereby forcing pressurized fluid out of the second piston cylinders (81) and simultaneously into the piston cylinders (61) of the tubular handling tool (60), thereby actuating the slips (66) into engagement with the tubular string.
