5.52.159.00.01.04
DANGER!
It is not permitted to use the unit in an area at risk from explosion!
4.2 Design
HADEF ratchet lever hoists are compact hoists
with suspension hook for stationary use.
Illustration 2
4.3 Functions
The load is lifted, lowered or tensioned by operating the lever. The load pressure brake prevents automatic
lowering of the load.
NOTICE!
If used "overhead" or "lashing" undefined forces may appear. We recommend to use a hoist with
slipping clutch for these cases.
NOTICE!
The best protection against functional failures in case of extreme environmental impact is the regular use of
the equipment.
4.4 Important components

Gear
Gear components are made of high-quality material.

Load pressure brake
Holds the load in any position.
A new brake system is used for the hoists. Brake
discs have sintered brake linings which, when
used appropriately, makes them wear-free for
lifetime of the hoists.
According to DIN 13157 lifetime is 1500 operating
cycles (lifting/lowering movements) with 300 mm
lift with nominal load.
Illustration 3

Housing
The housing is made of steel plate.

Load chain
According to EN 818-7-T high quality chain. All components match precisely to each other. Therefore please
only use original chains.

Load hook with safety catch.
Forged steel. Rotating, this facilitates attaching the load and avoids twisting of the chain.

Free-wheeling of chain
For pulling through of the uncharged chain.

5.52.159.00.01.04


Overload protection
Hoists with overload protection protect the hoist by a slipping clutch from damage by overload. When the
slipping clutch operates, lifting of the load is stopped. Lifting is only possible again after the load has been
lowered and reduced to nominal load.
4.4.1 Additional safety features
Additional safety mechanisms for increased functional and operation safety.

Release mechanism
Closes the brake for unintentional or
unforseeable opening of the load pressure
brake.
Even small traction forces that increase linear
are safeguarded reliably with the patented
HADEF-System!
Illustration 4

Locking mechanism
Locks the hoist completely in case of failure of:
Brake
and/or
Ratchet pawls
and/or
Release mechanism
Illustration 5
DANGER!
When the locking mechanism is activated, the hoist must no longer be operated. It must be overhauled by a
"qualified person"!
Chain guide device to feed in the chain
The chain is feeded into the hoist correcty even
for overhead work. Twisted chains are
aligned before they run into the hoist on the
chain sprocket wheel.
Illustration 6
(1) Chain lock (as option)
Adjustable, additional safety device for
downtime with load or tension.
Prevents reliably that the chain runs
unintended through the hoist.
(2) Chain end fastening

Illustration 12
NOTICE!
When free-wheeling is activated and chain is pulled through the divice, an increasind resistance
must be there with increased speed. This is no mistake .
7.2 Brake and pawl
The brake system needs a minimum load of 3% of the capacity.
Only this minimum load makes sure that the load-pressure-brake closes correctly. When the brake closes
correctly, the load is safely held.
DANGER!
Working situations with no guarantee that the minimum load is charged, are forbidden!
The brake remains closed (stuck) if:

The ratchet lever hoist is uncharged without lowering the load, i.e. in case of vertical lifting/lowering or in
case of horizontal pulling/tensioning.

The load hook is pulled against the housing and got stuck there.
The chain does not move, the load cannot be lowered.
Remedy:

Charge the ratchet lever hoist again

12 Service
12.1 Load chain
Wear at the links is mainly due to insufficient maintenance of the chain.
To ensure optimal lubrication of the links, the chain must be lubricated at regular intervals, depending on
usage.

Lubricate the chain with oil that creeps.

Always lubricate the chain when it is not under load so that the oil can wet the links affected by wear. It is
not sufficient to lubricate the chain from the outside, as this will not ensure the formation of a lubricating
film within the links. The adjacent link points must always be lubricated to prevent excessive wear.

If the same lifting operations are carried out constantly, the switching area from a lifting to a lowering
movement must be given special attention.

Thoroughly effected lubrication of the chain will prolong the life of the chain by approx. 20 times,
compared to dry run with unlubricated chain.

Wash dirty chain with petroleum or a similar cleaner, under no circumstances heat the chain.

If there are environmental influences that foster wear, such as sand, a dry lubricant should be used, e.g.
graphite powder.

When lubricating the chain’s condition of wear should be checked.
CAUTION!
Do not use grease for lubrication of load chain.
Without lubrication, manufacturer's warranty and/or liability will be void.

12.2 Pulleys
12.3 Load hook

Check bearings and pulleys yearly

Clean and lubricate the bearings of hooks and pulleys with grease

Slight bearings are maintenance free

When bearings resp. slight bearings are worn of, change the complete pulley
12.4 Gear
Regular checks of lubrication are necessary. The teeth must be cleaned and re-lubricated after approx. 3
years. We recommend to use a lubricant of class EP2 or similar products. In case of severe conditions of
use (e.g. dust, regular lifting of the nominal load,etc.), please shorten maintenance intervals.
12.5 Gear spring pressure brake
During the check, brake lining wear is verified. The brake linings must be replaced when the wear limit is
already reached at one position of the lining, - as this can be the case when wear of the linings is irregular.
CAUTION!
The brake linings must be free from fracture. Avoid oil, grease, dirt and humidity on the brake linings as this
increases wear.
The brake lining for the ratchet lever hoist is tested for the whole product lifetime - under the precondition of
appropriate use - and must only be replaced in case of extraordinary wear.
NOTICE!
According to EN 13157 lifetime is 1500 operating cycles (lifting/lowering movements) with 300 mm lift with
nominal load and normal operation conditions.
Use by heavy conditions can shorten the product lifetime. In these cases, the thickness of the brake lining
must be checked more than 1x yearly. The ratchet wheel with the brake lining must be replaced when the
wear limit is reached or wear of the lining (one one side) is clearly visible.
12.6 Overload protection
DANGER!
The factory setting of the overload protection/slipping clutch is secured by sealing. In case of any changes
will void the warranty. Should maintenance be necessary, please contact a service company authorized by
the manufacturer.
