POWERTEX Chain Sling in a Box PCSB 
Instruction for use (GB) (Original instructions)

General:

The work with lifting devices and equipment must be planned, organized, and executed to prevent hazardous situations.
In accordance with national statutory regulations lifting devices and equipment must only be used by someone well familiar with the work and 
having theoretical and practical knowledge of safe use. Before the equipment is used, the instruction manual must be read. It contains important 
information about how the equipment will work in a safe and correct way. If the equipment is used in accordance with this instruction manual risks 
and damages can be avoided. Apart from the instruction manual we refer to existing national regulations that may supersede these instructions.

POWERTEX chain slings are CE-marked and are delivered with a POWERTEX Certificate & Declaration of Conformity to Machinery Directive 

2006/42/EC. The slings follow EN 818-4 (Grade 8) with exception for higher WLL (+25%) and limitation of using temperature to max 200°C.

Use in adverse environments

Temperature’s effect on working load limit (WLL): 

Account should be taken to the temperature that can be reached by the chain sling in ser-

vice. POWERTEX chain slings in grade 10 can be used in temperatures between -40°C and +200°C without reduction of the working load limits.  

If the chain sling reaches temperatures that exceed the allowed temperatures the sling should be discarded or be returned to 

your distributor for evaluation

.

Acidic conditions

Chain slings in grade 10 should not be used either immersed in acidic solutions or exposed to acid fumes. Chain slings should for the same rea-

son, not be hot dip galvanized or exposed to electrolytic finishing without permission from the manufacturer.

Chemical affects

Consult with your distributor in case the slings are to be exposed to chemicals especially combined with high temperatures.

Hazardous conditions

In particularly hazardous conditions including offshore activities, lifting of a person, and lifting of potentially dangerous loads such as molten me

-

tals, corrosive materials or fissile materials, the degree of hazard should be assessed by a competent person and the working load limit adjusted 

accordingly.

Before first use

Before first use of the chain sling the user should ensure that:

a)

 the sling is precisely as ordered;

b)

 the manufacturer’s Certificate/Declaration of Conformity and User manual is at hand;

c)

 the identification and working load limit marking on the sling correspond to the information on the certificate;

d)

 full details of the sling are recorded in a register of slings;

Before each use

Before each use, the chain sling should be inspected for obvious damage or deterioration. If faults are found during this inspection, the procedure 
given in “Inspection and maintenance” should be followed.

Choosing the correct chain sling

Mass of the load:

 It is essential that the mass of the load to be lifted is known.

Method of connection:

 A chain sling is usually attached to the load and the lifting machine by means of terminal fittings such as hooks and links. 

Chains should always be used without twists or knots. Use the shortening hooks to adjust chain legs that needs shortening.

The lifting point should be well seated inside the hook, never on the point or wedged into the opening. The hook should be free to incline in any 

direction to avoid bending. For the same reason, the master link should be free to incline in any direction on the hook to which it is fitted.

The chain may be passed under or through the load to form a choke hitch or basket hitch. Where it is necessary, due to the danger of the load 

tilting, to use more than one chain sling leg in a basket hitch, this should preferably be done in conjunction with a lifting beam.

When a chain sling is used in a choke hitch, the chain should be allowed to assume its natural angle and should not be hammered down.

Chain slings may be attached to the load in several ways

Straight leg:

 In this case lower terminals are connected directly to the attachment points. 

Selection of hooks and attachment points should be such that the load is carried in the seat of 
the hook and tip loading of the hook is avoided. In the case of multi-leg chain slings hook tips 

should point outwards unless the hooks are specifically designed to be used otherwise.

Choke hitch:

 In this case chain sling legs are passed through or under the load and the lower 

terminal back hooked or reeved onto the chain. This method can, therefore, be used where no 
suitable attachment points are available and has the additional advantage that the chain sling 
legs tend to bind the load together.
Where choke hitch is employed the working load limit (WLL) of the chain sling should be no 
more than 80% of that marked.
