1 Safety information
1.1 General
The safety of Hilma-Roemheld swing clamping cylinders has been thoroughly checked. They are designed for
use as specified in the technical data. If the technical data is not observed, there may be a danger to the
operator and proper functioning of the machine may be put at risk. Unauthorised modification or alteration of
Hilma-Römheld pull clamping cylinders is prohibited for reasons of safety. If this instruction is not observed, our
guarantee will be invalid.
1.2 Field of application
Hilma-Römhelld swing clamping elements are designed for a large number of clamping applications, in
connection with screw or tie rods or T-bolt supports. Swing clamping cylinders type 2170 are particularly suited
for the clamping of dies on presses when standardised dies with clamping slots or Hilma- clamping flanges are
used.
1.3 Operating characteristics
The load values specified for Hilma Römheld swing clamping cylinders must not be exceeded (see data sheets
in the appendix).
Attention: Overloading the swing clamping cylinders may lead to failure of the elements or to their
destruction.
1.4 Temperatures
The maximum operating temperature for the standard design is 70 °C. In case of higher temperatures special
designs with high-temperature sealing must be used (special designs for max. temperatures of 230°C without
proximity switches)
1.5 Important safety information
-Depending on the installation, there may be pinch hazard between the swing clamping element and the
clamping point
-Keep hands and tools away from the clamping range when operating the hollow piston cylinders.
Attention:
Before putting the swing clamping cylinders into operation, the operator must be fully trained.
Young people less than 16 years old are not allowed to operate the clamps. Staff aged over 16 years are
allowed to operate the clamps under supervision as part of their apprenticeship. The operating instructions must
be readily accessible. The operator must inform third parties of any danger in the working area.
