1. General info about lifting points

Definition/explanation: Lifting points are a connection between load and lifting equipment (e.g. sling chains, sling ropes, lifting slings) that are needed when loads have to be lifted or moved.

There are the following types of lifting points:

Rigid lifting points

consist of eyebolts or weldable eyelets
since the direction of pull cannot be changed, they are often used for single strand solutions
Not flexible

Rotatable / foldable lifting points

They are used when using multiple strands, as the attachment points must align themselves in the direction of the hoist before the lifting operation is performed
are more flexible than rigid lifting points

Up to four attachment points can be used. Depending on the nature of the load, the attachment points are distributed on it. When attaching, care is taken to ensure that the load hangs straight during the lifting process and does not tilt, for example. If this is difficult or not feasible, use special slings. Care must be taken to ensure that the anchor point is adequately sized and secured. In addition, the angle plays a load, because depending on the angle, the load capacity changes. Flat angle: 45-60°. Steep angle: 0-45

2. attachment of the anchor points

Welded

When the lifting point is welded on, the welding instructions must be followed
the weld seam must be checked for correctness

Bolted on

the operating instructions must be observed
Load and material must be suitable so that the lifting point can be screwed in deep enough

Special design needed?
Many of our sling swivels are available in a wide variety of thread types and lengths upon request. We supply e.g.:

metric thread standard
metric fine thread
UNC inch thread
UNf inch thread
UN inch thread
UNS inch thread
UNJ inch thread
UNJF+BSW+BSF inch thread

Special painting, equipment with nut and washer or threaded screws with smooth part and thread are also available.
In addition, DSR + DSS + DSH + TSR type slings can be supplied with a bracket for the shackle. With this bracket, the load bar is freely adjustable in various load directions, but can still rotate freely in the event of any existing obstacles.

4. doComfort sling swivel in grade 10

Stop swivel DoComfort Premium

DoComfort Swivel Stop Premium Grade 10 Dolezych

The DoComfort sling swivel is the logical further development of the already known sling swivel 0950 in grade 8 and grade 10. Increase of the load capacity by 25% and compliance with the mass of the current grade 10 sling swivels.

Better rotational behavior due to additional ball bearing, thus better rotation under full and transverse load at 90°.
New clear indication of the inclination angles of 45° or 60° by marking on the pick-up element.
New visible wear indicator of the ball bearing, thus discard maturity can be detected without measuring tool.
Improved contact surface due to mechanically formed support surface, with load capacity marking (chrome-6-free according to EU directives). Corrosion protection by galvanic coating, seal prevents dirt penetration.
with ball bearing
180° swiveling
360° rotatable under load
Load capacity from 0.3 t to 50 t
Thread from 8 x 18 mm to 100 x 150 mm

Other thread sizes, e.g. inch and round threads, as well as deviating threads in diameter and length are alternatively available in special designs. Possible tightening torque in Nm for DoComfort stop swivel.

All commercially available thread designs from inch to round thread are available. Different threads are available.
(TPSO) Tightening torques: tightening with open-end wrench according to DIN 895 or 894 without the aid of an extension is practicable and sufficient in these clamps.
Available with RFID on request.

Stop swivel DoComfort Premium IG

Stop swivel IT with internal thread. The standard thread depth is 1.25 x d. Only grade 10.9 crack-tested screws are permitted as fasteners. Different thread designs and lengths are available on request. The stop swivel must not be used for continuous rotary motion under load.

With internal thread
180° swiveling
360° rotatable under load
Load capacity from 0.5 t to 15 t
Thread from 12 x 15 mm to 36 x 45 mm

5. Lifting points according to safety factor

Stop swivel 0958 DSR universal

In the case of sling swivel 0958, the load distribution is distributed over the entire cross-section (i.e. one surface) and not over individual ball bearings. This has an effect on the load-carrying capacity in inclined tension. Another advantage is the durability of the bearing.

screwable with thread
Bracket 180° swiveling
360° rotatable with full load capacity
special grade steel quality
Continuous rotation under load not permitted!
Safety factor 5
Load capacities from 0.07 t to 8.5 t

Stop swivel 0958 DSS universal

screwable with thread
Bracket 180° swiveling
360° rotatable with full load capacity
special grade steel quality
Continuous rotation under load not permitted!
Safety factor 5
Load capacities from 4.5 t to 25.0 t
Thread diameter from M 24 x 3 to M 100 x 6

*Thestop swivel must be tightened according to the tightening torque indicated on it and with the help of a torque wrench for each application with shackle rotation. For lifts without shackle rotation, the sling swivel can be hand-tightened under the following conditions: The user must ensure that the hand-tight tightening is correct and that the base is fully supported on the load. During each lifting, check that the base is correctly supported on the load.
