2.5 Application areas
Here we can differentiate between three significant areas of
application:
• the slinging of a load in direct tension
• (see chapter 5 “Direct tension” on page 5 - 9)
• the slinging of a load in indirect tension
• (see chapter 5 “Indirect tension” on page 5 - 10)
• the slinging of a load with a lifting strap in choke hitch
• see chapter 5 “Types of Loading/Max. Weights (Lifting Strap)”
on page 5 - 4
2.5.1 Direct tension
The load is fixed directly onto the hook of the LUDWIG HOOK.
In this application, a shackle is attached to the hole in the cap on the
LUDWIG HOOK. This can then, in turn, be attached to a load hood. The
load itself is fixed directly onto the hook of the LUDWIG HOOK.
2.5.2 Indirect tension
A second strand (in the form of a chain, lifting strap) is attached to the
load hook, alongside the LUDWIG HOOK.
The second strand is placed around the load or threaded through an
eye on the load and then hung back into the LUDWIG HOOK.
2.5.3 Choke hitch with lifting strap
For lifting loads that have a choke hitch with a lifting strap. The lifting
strap is threaded through the side eye-bolts on the LUDWIG HOOK´s.
