POWERTEX Chain Block PCB-S1 0.25 – 20 tonnes
Instruction for use (GB) (Original instructions)

Read through these user instructions carefully before using the chain block. Improper operation may lead to hazardous situations!

General safety provisions

• Check the function of the chain block before use. See “Daily checks” on page 3.

• Full function of the brake system can only be secured at a minimum load of 30 kg for capacities (WLL) up to 1 ton,
and for capacities (WLL) above 1 ton, the minimum load to be greater than 3% of the rated capacity (WLL).

• Do not exceed the maximum load.

• Handle the chain block with care. Do not throw the block about or let it fall to the ground.

• Do not use the chain block for welding work where it is exposed to welding spatter or current.

• The chain block must not be used for lifting persons.

Technical data

Safety factor : 4:1.

Static test coefcient: WLL x 1,5.
Generally according to EN 13157.

Function

The load hook is raised or lowered by pulling on the hand chain. The load will remain where it is even when the hand chain is released because
of the effective reaction brake.

Suspension of chain block

Suspend the block from an eye, shackle, girder trolley etc. with sufcient load capacity. With the chain tightened, both hooks must be vertically

aligned.

NB! No bending stresses may be applied to block, hooks or load chain.

Raising/lowering

Only use straps and slings of sufcient load capacity. Check that the load is not anchored to the oor/ground or is otherwise xed before making

the lift. Ensure that the load chain hangs vertically and has no kinks. The hand chain must also be in good condition and easily accessible. The
load is raised or lowered by pulling the hand chain in either direction.

Warning:

• Only hand power from a single person is permitted on the hand chain. If the chain feels too heavy, use a bigger chain block or reduce the
load.

• Make sure no-one stands beneath a hanging load.

• Do not step onto a hanging load.

• Do not raise or lower so far that the load hook hits the block housing.

• The chain block must not be used for pulling loads.

• The block must not be subjected to dynamic stresses, for example where a load connected to the block is launched from a height.

• Do not leave a block with a suspended load unattended.

Attachment of loads

Check the equipment before use. Improper attachment of loads can be highly dangerous (see Figs. 2 a – 2 e).

Multiple lifting

Multiple lifting presents special risks. This is when two or perhaps more hoists are used simultaneously for the same load. Danger to persons and
material damage can arise due to dynamic stresses and uneven load distribution causing individual hoists to become overloaded. A competent
person with experience in multiple lifting must therefore supervise this type of lifting tasks.
The total weight of the target object and its load distribution must be known or calculated.

For a variety of reasons, the centre of gravity can be difcult to determine, and thus so will the distribution of the load each hoist must bear. In

cases where heavy, bulky loads must be handled and it is not possible to estimate all factors correctly, the max working load limit (WLL) of each

hoist must be reduced by at least 25%.

Daily checks

After every working day on which the chain block has been used, the following should be checked:

• Is the chain block deformed or otherwise damaged? Are any parts missing?

• Is any deformation or other damage visible on the suspension device (eye, shackle, bolt, trolley etc.)?

• Are the hooks intact or have any hooks opened? Are the hook latches correct and functional?

• Wipe down the chain block and oil the load chain as required.

• The load chain must be undamaged, i.e. no signs of wear and no deformed or otherwise damaged links.

• The load chain must not be kinked or twisted. With two-fall or multi-fall chain blocks there is a risk of the chain twisting if the bottom hook

assembly ends up looped through the chain sling – usually during retting or moving the chain block between work stations. See Fig 3.

• The hand chain must also be in good condition.

• The brake function must be intact.
In the event of faults or failures, the block must be repaired and carefully checked by a specialist before reuse.

Continuous maintenance - lubrication

Oil the hook latches and bearings. Grease the pawl and ratchet and also the gear. Lubrication must be sparingly and carefully applied so no grea­se gets on the brake disk. Oil the load chain for longer life.

Periodic checks

Periodic checks are normally carried out yearly to detect and remedy any faults. If required (e.g. high frequency of use), more frequent checks
may be carried out. See “Checklist for periodic checks”. Measure hooks and chain to detect any changes in shape.

Checks on load hook (see Fig. 4 and Table 1)

Opening dimension l on the hooks is important. A hook with too
large a maximum dimension has been exposed to overloading
or overheating. It therefore does not have the necessary load
capacity. The hooks may also have been exposed to long-term
wear (dimension K).

Hooks must be discarded and replaced if:

• The maximum l value is exceeded (according to Table 1)

• The minimum K value falls short (according to Table 1)

• The hook shows signs of cracking

• The hook is deformed or otherwise damaged
Defective hooks must be replaced before using the chain block

again.

Checks on load chain (see Fig. 5 and Table 2)

Inspect the load chain over its whole length to detect any deformed or otherwise damaged links. Make a check measurement of suspect links.
Measure the worn areas Also, every 300 mm (normally), make check measurements of the internal length of 5 links (pitch dimension 5xP – ac­cording to Table 2).

The load chain must be discarded and replaced if:

• cracks are detected on any link

• any link is deformed or otherwise damaged

• The minimum value of any link’s diameter falls short

• the maximum value of the pitch dimension is exceeded at any point

• the chain is damaged by overheating or has been affected by weld splatter
Load chains must not be repaired – they must be replaced by new chain. If it is desired to lengthen the chain, it must be replaced by a new and

longer chain.
Replacement of the chain shall be performed professionally by an authorized repairer and the chain must meet the requirements stated in the

standard EN 818-7 from the following manufacturers: Chaineries Limousines, Pewag, Thiele or Rud

Repairs

The chain block must not be modied. Repairs must be carried out by specialists. Damaged parts must only be replaced with original Powertex

spare parts. Order them through your dealer.
