Important Safety Precautions
DANGER
Failure to follow the safety precautions below will result in
serious injury or death.
Provide sufficient strength for the draw pipe (Refer to pages 48-49).
Provide sufficient screw depth for the draw pipe.
Firmly tighten the draw pipe.
・
If the draw pipe break, the gripping force is instantly
lost and this is dangerous as work will fly out.
・
If the screw depth of the draw pipe is insufficient, the
screw will break and the gripping force will be lost
instantly, and this is dangerous as work will fly out.
・
If the engagement of the screw of the draw pipe is
loose, vibration may occur resulting in breakage of
the screw. If the screw breaks, the gripping force will
be lost instantly, which is dangerous as the work will
fly out.
・
If the draw pipe is unbalanced, vibration occurs, the
screw is broken and the gripping force will be lost
instantly, which is dangerous as the work will fly out.
Use a cylinder with a lock valve (safety valve, check valve) incorporated in
case of sudden hydraulic pressure drop due to blackout, malfunction of
the hydraulic pump, etc. Further, use a solenoid valve with a circuit that
retains the gripping position when no current is carried.
・
If the hydraulic pressure
suddenly drops due to blackout
or malfunction of the hydraulic
pump, etc., this is dangerous
as work will fly out.
・
Lock valve retains the hydraulic
pressure inside the cylinder
temporarily, when the hydraulic
pressure suddenly drops due
to blackout or malfunction of
the hydraulic pump, etc.
