system |
|
| Fork connector |
Using computer-supported FEM analysis we have succeeded
in creating a new shape and weight-optimized fork connector design. An almost
uniform tension distribution over the entire cross-section opens up new
application possibilities with regard to material fatigue.
The
characteristic design in conjunction with the recessed pin lock result in an
unmistakable overall concept. The recesses in the flanks on the sides enable the
viewer to recognize and understand the force curve.
|
| Components |
The components, consisting of the fork connector, pins,
turnbuckle, coupler and circular plate, are designed so that they can absorb
higher loads than the tie-rod. To ensure the full load-bearing capacity of the
system in the area of the connection design, only connection plates of quality
S355J2G3 according to EN 10025 may be used.
As an option, we offer thread
cover sleeves as an accessory.
| |
| These enable a harmonious transition from the tie-rod to
the fork connector, turnbuckle or coupler connection components. In addition,
the tie-rod thread is hidden and simultaneously locked. Thread cover sleeves for
fork connectors are also supplied in a cast finish. In combination with the fork
connector a smooth, uniform, appearance results. |
| Corrosion protection |
Optimum corrosion protection for the systems ASDO-S and
ASDO-DS is offered by hot-galvanizing according to ISO 1461.
For system sizes
up to M 42 we supply forks, pin sets, turnbuckles, couplers and thread cover
sleeves hot-galvanized as standard.
The threads are remachined to size
following galvanizing; repairs to zinc coating are made in accordance with the
applicable standards.
Spanner flats on the tie-rods are pressed following
hot-galvanizing to prevent brittle fracture.
As an alternative, the systems
can also be supplied in a sand-blasted and primed
condition. | |
| Adjustment options |
The system length for all ASDO systems is defined as the
distance from pin centre to pin centre.The arrangement of opposing
right/left-hand threads in the system enables exact adjustment of the length on
installation. For smaller diameter systems adjustment is easily carried out by
turning the tie-rod in the fork connectors.
However, larger diameter systems,
due to their high-self-weight should always be equipped with a turnbuckle to
enable adjustment when installed.
|
| Pretensioning |
Certain designs or applications require tie-rods to be
tensioned after installation to a desired load. Where this is required a
turnbuckle is imperative. With it a defined load can be placed into the system
by means of the SPA hydraulic tensioning device.
The device is mounted via
thread cover sleeves, special nuts or free tie-rod threads. The SPA can be used
for all nominal sizes and has basic models with a capacity of 20 to 200
tonnes.
Notification of planned pretensioning must be provided in
advance. | | Download of the installation directives for the
