See . The SQD torque wrench consists of
a wrench body (1), 360° swivel hose
connection (2),
mechanism (3), square drive (4), drive release
(5) and reaction arm (6) for square drive.
Optional are the Allen-key drive (7) and
reaction arm (8) for Allen-key drives. This
reaction arm (8) must be used when inserting
the Allen-key drive (7) to tighten or loosen
socket head cap screws.
Advance and retract oil flow on the pump
must be controlled by electric valves with
cables or pneumatic valves with air hoses,
so that at any time control is possible of the
Enerpac wrench.
The advance pressure (A or P) from the
pump to the wrench must be limited to a
maximum 800 bar [11,600 psi]. The pressure
relief valve at the retract side (B or T) of the
pump must be set to a maximum 120 bar
[1740 psi]. See tables
the pages 12-17 for detailed information.
