Synthetic Slings are required to have a periodic inspection at intervals of service of not more than three months. The slings shall be inspected by a competent person. For heavily used slings the inspections should be more frequent. A record of every periodic inspection including all details shall be kept
Minimum Breaking Force (MBF) - MBF is the minimum load or force, specified by the manufacturer, at which the wire rope will break. This is the figure which should be used when choosing the right wire rope for your application Working Load Limit (WLL) - The WLL is the load that a wire rope can carry on a particular application. The WLL should be based on the MBL, not the actual breaking force. AS1666 specifies the design factors for wire ropes...
All assets must have traceability throughout their lifecycle. If a lifting sling has lost its tag and a permanent method of identification is not evident, then the item should be withdrawn from service. See LiftQuip Australia Slings Further Information - Contact LiftQuip Australia today
It doesn't matter what the asset is that you are maintaining, one of the most important aspects of an inspection process is the recording of information. Important information needed is the specific serial number of the asset, date of inspection, the condition of the item, as well as who performed the inspection
Chain Sings – Inspection Frequency The latest revision to AS3775 provides a guide on how often periodic inspections should take place. Your duty of care is that you shall have an inspection program in place which takes into account the particular circumstances of use.
WIRE ROPE – Installing under load To achieve perfect multiple layer spooling of the rope on the drum it is important to put tension on the rope during the installation It is critical that the first layers are under tension. If they are too loose, top layers may wedge in under load which could result in damage to the rope and lead to discard. Tensioning of the load should range between 1% to 2% of the MBL (minimum breaking load) of the rope.
LOAD RESTRAINT – The Golden Rule: Minimum Horizontal Restraint Required Restraint against forward movement = 80% of the load Restraint against sideways movement (Left) = 50% of the load Restraint against sideways movement (Right) = 50% of the load Restraint against rearward movement = 50% of the load Restraint against vertical movement = 20% of the load
LOAD RESTRAINT – Responsibilities It is the responsibility of the owner, the driver and the person in charge of loading, to ensure that the vehicle’s load restraint structure, attachments and load restraint equipment are suitable for the application and are serviceable and functional It is the responsibility of the person in charge of loading and the driver, to ensure that a load is properly restrained by the vehicle load restraint structure, attachments and load restraint equipment using safe operating procedures ...
