6.2 attachment type 2724
The leveling supports type 2724 are offered in three different confi-
gurations. These differ only in the upper connection. There are three
different interchangeable adapters available, which can be selected
depending on the connection possibility at the container.
1) Version (attached with adapter1)
– Attachment analogous to 8251 (–> 6.1. Attachment type 8251)t
2) Version (attached with adapter2)
– Screw the adapter plate (9) to each corner of container depending on
the height of the leveling support.
– Set up the leveling support (1) vertically.
– Hang the lifting arm (4) of the support into the slot in the adapter
plate (9).
– Then attach the lower fitting (2) of the leveling support (1) into the
ISO corner (3) of the container and slide it in.
– Turn the locking screw (6) on the side of the dowel pin (8) by 90°, pull
it towards the support (1) and secure this position hand-tight with the
hexagon nut (7)
– Before finally tightening the screw (6), push the leveling support (1)
up as far as possible.
– The lower shaped piece (2) of the leveling support (1) must touch the
corner fitting of the cantainer (3) with the upper edge.
– Tighten the screw (150Nm) and fix the position of the support.
3) Version (screwed with adapter3)
– Screw or weld the adapter plate (9) to each corner of the container,
depending on the height of the leveling support.
– Set up the leveling support (1) in the right direction. Insert the lower
fitting (2) of the leveling support into the ISO corner of the container.
– Position the upper extension arm (4) in the groove adapter plate (9)
and fix it hand-tight with the screws (5).
– Turn the locking screw (6) on the side of the dowel pin (8) by 90°, pull
it towards the support (1) and secure this position hand-tight with the
hexagon nut (7).
– Before finally tightening the screw (5). (6), push the level support (1)
up as far as possible.
– The lower shaped piece (2) of the leveling support (1) must touch the
corner fitting of the container (3) with the upper edge.
– Tighten the screw (150Nm) and fix the position of the support.

– The disassembly of the support leg (1) must be done in reverse order.
–
Before untightening the screws ensure that there is no load on
the suporrt leg.
7. operation
Check the secure fastening of the supports before each
operation. Tighten the screw connection if necessary.
The extension of the levelling jack is made by turning the crank clock-
wise. To pull in the spindle support it must be turned counter-clockwise.
When the lift stop is reached (rise of the crank force!), the cranking has
to be stopped, in order to avoid damages of the spindle support.
When the crank is released, the load will be maintained in any position

by the self-locking spindle.
The spindle winch type 2724.25 is additional equipped with a gearbox
with 2 gears:
fast gear: for the fast extension of the unloaded winch.
low gear: for the extension of the loaded winch.
choose fast gear: Using the mounted crank the different gears can be
switched by pulling out.
choose low gear: Using the mounted crank the different gears can be
switched by pressing in.
attention!
The locking mechanism may only be released, when the level-
ling device is unloaded.
attention!
Ensure that the individual corner units are cranked evenly and
simultaneously to prevent any overload of the different corner
units.
8. testing
The equipment must be inspected in accordance with the conditions of
use and the operating conditions at least once per year by an authorised
person for testing per TRBS 1203 (Technical expert) (testing per BetrSi-
chV, §10, sect.2 represents implementation of EC Directives 89/391/EEC
and 2009/104/EC and the annual occupational safety inspection per
DGUV-V 54, §23, sect. 2 and DGUV-G 309-007).
These inspections must be documented:
– Before commissioning.
– After significant alterations before recommissioning.
– At least once per year.
– In the event of unusual occurrences arising that could have detrimen-
tal effects on the safety of the levelling jack (extraordinary tests, e.g.
after a long period of inactivity, accidents, natural events).
– After repair works that could have an influence on the safety of the
levelling jack.
Technical experts are persons, who have sufficient knowledge based
on their specialist training and experience, in the areas of winches, lift
and pull systems, and familiarity with the relevant official occupational
health and safety rules, accident prevention regulations, guidelines and
generally accepted engineering rules (e.g. EN standards), to evaluate
the operational safety of winches, and lift and pull systems. Technical
experts are selected and comissioned by the operator of the equip-
ment.
9. Maintenance recoMMenDation
The operator determines the intervals themselves based on frequency
of use and the operating conditions.
– Regular cleaning, no steam jets!
(Adapter 3)
– General overhaul by the manufacturer after 10 years at the latest.
caUtion!
Only perform inspection, maintenance and repair work on an
unloaded hoist. Only allow work on safety components to be
performed by qualified specialist personnel.
