DESCRIPTION
Covered under Patent No. 5,371,933
The
GB510L/LGP is a hydraulic installation tool designed specifically for the efficient installation of a
5/16" diameter LGP lockbolt. It weighs just under 4 lbs. and can be operated in any position with one
hand. It has a .500 rivet setting stroke.
The GB510L/LGP installation tool operates on hydraulic pressure developed by the GBP940 Powerunit
or the GBP910A powerunit, set at 5600 psi maximum PULL pressure and 2400 psi maximum RETURN
pressure.
ALL GBP HYDRAULIC INSTALLATION TOOLS ARE COMPATIBLE WITH HUCK POWERIG'S.
OPERATION
When a signal is sent to the powerunit, a directional valve in the Powerunit directs fluid to the front side
of the piston forcing it and the nose assembly collet rearward. This action causes the jaws to clamp on
the fastener pintail and pull the material together. During a lockbolt installation sequence, the anvil is
forced over the collar, swaging it into locking the grooves of the fastener. Further force breaks the
pintail off approximately flush with the collar. The pull-in sequence is started in the same manner, but
the pull-in mandrel may be grabbed a number of times. Releasing the trigger allows the operator to
advance the tool on the pin for installations that require greater than .500 stroke.
When the piston nears the end of its stroke it exposes flats on the back of the unloading valve. These
flats "dump" fluid back to the Powerunit tank. When the button is released the directional valve reverses
fluid flow to the back of the piston and pushes the nose assembly off to the swaged fastener. The spent
pintail is forced out the back of the nose assembly with the insertion of the next fastener.
MAINTENANCE
The performance of any tool depends upon the practice of good maintenance.
Following these minimal requirements for service and care will extend the life of your tool.
*Only use a hydraulic power source equipped with relief valves and pressures set within specified limits.
*Consult Powerunit Manual for procedure to set Pull and Return pressures.
*Keep hydraulic system free of dirt. Avoid letting couplers contact a dirty floor.
*Do not use as a hammer to force fasteners into holes or otherwise abuse tool.
*Proper care by operators is necessary in maintaining full productivity and reducing down time.
WARNING
Be sure Powerunit is disconnected before cleaning, or when replacing worn or damaged components.
Severe personal injury may occur if power source is not disconnected.
