3. Description of Functions
Place the clamp in the open position on the object, so that the legs of the clamp are fully on the object. Ensure that
the plate surface where the clip is to be placed is completely free of dirt, grease, oil, corrosion and contamination;
then swivel the safety lever. When the crane starts lifting the clamp will close; support the clamp until it is tight and
then continue lifting. When the load reaches its destination allow the hook to drop down far enough so that the
clamp is not under any load, i.e. the lifting chain is no longer tight and the clamp with chain can be moved freely.
Now close the safety lever. The clamp can now be used again immediately or stored in the open position.
4. Safety Instructions
Remember: Safety first! Especially where your personal safety and that of people in the immediate vicinity is
concerned. Carefully read the following safety instructions before using your new BLCW safety lifting clamp.
Ensure your own safety and continue to benefit from our product safety by having the clamp inspected, tested, and,
if necessary, overhauled at least once (1x) a year by pewag austria GmbH or another recognised mechanical repair
and service centre. See also Chapter 8 – Overhaul. It is not permitted to make any structural modifications to the
clamps, for example by means of welding or grinding. Please contact pewag austria GmbH for further information.
Temperature
The operating temperature of the pewag BLCW lifting clamps is between -10 °C (14 °F) and +30 °C (86 °F).
Please consult with your dealer if other ambient temperatures are applied.
Loads
Due to their wide gripping range our clamps are suitable for lifting and transporting a variety of different objects.
The clamping jaws are not suitable for placing on inclined or conical shaped surfaces. If the crane hook has no safety
device and/or is too big and too heavy, use a length of chain with masterlink-closure of approximately 75 cm
(30 inch) length with a strength that corresponds to the WLL of the clamp in order to ensure that when the load
hook is rested down the crane operator does not allow the hook to drop so far that it falls out of the lifting eye. When
hanging directly on the crane hook with safety device ensure that the crane hook can move freely in the lifting eye.
Avoid life-threatening situations
Avoid life-threatening situations by complying with the following guidelines:
• Never operate an untested lifting clamp
• Always keep a distance during the hoisting operation and never stand underneath the load
• Do not use the clamp if it is damaged. Have the clamp repaired by pewag austria GmbH or another authorised
mechanical repair and service centre. When in doubt: contact your supplier
• Never hoist more than one plate at a time
• Never hoist loads heavier than the safe working load limit (WLL), as is clearly indicated on the clamp and the test
certificate
• Never hoist loads that are thicker or thinner than the clamp opening, as indicated on the clamp and the test
certificate
• When using more than one lifting clamp at the same time, arranged in a row, provide lifting slings or chains of a
sufficient length to ensure that the angle between the slings or chains does not exceed 60 degrees
• When using more than one lifting clamp at the same time, arranged in parallel, use a trussed hoisting girder
(equalising traverse girder) and sufficiently long lifting slings or chains, so that the lifting eye of the lifting clamp is
never subjected to a lateral load
• Never place the clamp onto tapered or conical parts of the load to be hoisted
• Remove all grease, oil, corrosion and contamination from the plate at the point where the lifting clamp is to be
attached
• The clamp is only suitable for use in normal atmospheric conditions
Safety precautions
• A free fall or uncontrolled swaying movement at the crane hook resulting in objects being struck may cause
damage to the clamp. If this occurs, check whether the clamp is in good working order before use it again
• Lifting clamps are not suitable for creating permanent joints
• Preventive maintenance to the clamp should be carried out on a monthly basis. See Chapter 6 – Maintenance
• Do not perform structural modifications to the clamp (such as by welding, grinding, etc.). Such modifications may
adversely affect its operation and safety, thereby nullifying any foms of warranty and product liability
• This is also the reason to only make use of original pewag replacement parts
• Any improper use of the clamp and/or failure to observe all directions and warnings in this user's manual
concerning the use of this product may endanger the health of the user and/or people in the immediate vicinity
