The hydraulic pressure applied to the wrench
is converted into torque by means of a
hydraulic cylinder and a drive lever.
See
. The HXD torque wrench consists of
a wrench body (1) with 360° swivel hose
connection (2), two dowel pins (3) and
integrated support arm (5).
The CC-Interchangeable Cassette (4) must
be ordered separately as well as IN-Hexagon
reducer inserts (6) and HR-Holding rings (7).
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
,
,
and
on
the pages 12-19 for detailed information.
3.0 SAFETY ISSUES
Failure to comply with the
following cautions and warnings
could cause equipment damage
and personal injury.
IMPORTANT:
Minimum age of
the operator must be 18 years.
The operator must have read and
understood all instructions,
safety issues, cautions and warnings before
starting to operate the Enerpac torque
wrench. The operator is responsible for his
activity towards other persons.
WARNING:
To avoid personal
injury and possible equipment
damage, make sure all hydraulic
components withstand the
maximum pressure of 800 bar [11,600 psi].
IMPORTANT:
Minimize the risk of
overloading. Use hydraulic
gauges in each hydraulic system
to indicate safe operating loads.
It is your window to what is happening in the
system.
WARNING:
Do not overload
equipment. Overloading causes
equipment failure and possible
personal injury.
CAUTION:
Make sure that all
system components are
protected from external sources
of damage, such as excessive
heat, flame, moving machine parts, sharp
edges and corrosive chemicals.
CAUTION:
Avoid sharp bends
and kinks that will cause severe
back-up pressure in hoses.
Bends and kinks lead to
premature hose failure.
WARNING:
Immediately replace
worn or damaged parts with
genuine Enerpac parts. Enerpac
parts are designed to fit properly
and withstand rated loads.
WARNING:
Always wear safety
glasses. The operator must take
precaution against injury due to
failure of the tool or workpiece.
DANGER:
Do not handle
pressurized hoses. Escaping oil
under pressure can penetrate the
skin, causing serious injury. If oil
is injected under the skin, see a doctor
immediately.
WARNING:
Never pressurize
uncoupled couplers. Only use
hydraulic equipment in a coupled
system.
