Safety Shock Absorbers SDH38 (high rack damper, optimised characteristic)

Mounting instructions and mounting accessories

Installation instructions

Before installation and use check whether the identification num-

ber on the damper or on the packaging matches the respective

designation on the delivery note.

Operating temperature range: -20 °C to +60 °C

Mounting: As required but always in such a way that the entire

damper stroke is used. The dampers must always be mounted

in such a way that the forces are introduced centrally over the

piston rod in the damper. The maximum side load angle must

not be exceeded. Safety dampers must not be exchanged from

one installation site to another if the conformity of the throttle

characteristic curve is not ensured.

WARNING

Take particular care that the customer-specific

identification number at the end of the damper designation

matches the number on the delivery note. The field data

to be read from the type plate, such as moving mass and

maximum impact velocity, must be compared with the

technical design. This ensures that the damper is the right

size for its use. Otherwise you risk damaging the shock

absorbers and/or machine by overstressing materials.

The gas accumulators of the SDH38 to SDH63 safety shock

absorbers are filled with nitrogen ex works. The respective

filling pressure (5 bar) can be found on the damper

label. The dampers may only be operated with this filling

pressure. A reduced filling pressure can lead to serious

malfunctions.

During installation of the dampers, moving masses can

lead to injuries due to inadvertent starting. Secure moving

masses against inadvertent moving.

The dampers may be unsuitable for use and have an

insufficient damping effect. Check the specific suitability

of the dampers before installation.

If operated outside of the operating temperature range,

the damper can lose its function. Operating temperature

range must be maintained. Do not paint dampers due to

heat emission.

Fluids, gases and dirt particles in the surrounding area can

attack or destroy the seal system of the damper and cause

it to fail. Protect or encapsulate piston rod and seal system

from external materials in the surrounding area.

Damage to the piston rod surface can destroy the seal

system. Do not grease, oil piston rod etc. and protect

against dirt particles.

The piston rod can be torn from the damper. Do not load

the piston rod with tensile stress.

Damper can tear off upon impact. Always lay out the

connection structure in such a way that the maximum

occurring forces can be absorbed with sufficient safety.

Safety shock absorber check after a damper impact.

Check that the piston rod returns to the initial position,

the damper is not leaking and the mounting elements are

properly secured.

Emergency stop application: After an emergency stop, check

that the piston rod returns to the initial position, the damper is not

leaking and the mounting elements are properly secured. Make

sure that no damage has occurred to the piston rod, the body, or

the mounting hardware.

Regular start-up: Safety shock absorbers can be regularly

started up with 100 % stroke utilisation with a creep speed of 1/10

of the max. impact velocity.

Checking: A regular check should take place at an interval of no

more than three months.

Commissioning

First impacts on the shock absorber should only be tried after

correctly mounting and with reduced impact velocity and – if

possible – with reduced load. Differences between calculated and

actual operating data can then be detected early on, and damage

to the system can be avoided. If the safety dampers were selected

on calculated data that does not correspond to the maximum

possible loading (i.e. selection based on drive power being

switched off or at reduced impact velocity) then these restricted

impact conditions must not be exceeded during initial testing

or subsequent use of the system. Otherwise you risk damaging

the shock absorbers and/or machine by overstressing materials.

After the initial trial, check that the piston rod fully extends again

and that there are no signs of oil leakage. Also check that the

mounting hardware is still securely tightened. Make sure that no

damage has occurred to the piston rod, the body, or the mounting

hardware.
