A list of provisions that have been developed since in the B include ones that apply to the construction & operation of below-the-hook lifting devices.


Below the Hook Lifters are those helpful pieces of equipment that provide a connection point between the crane and the load being lifted. They can be structural mechanical lifting devices, vacuum lifters, magnets, and grapples. In order to provide direction regarding the design, marking, installation, inspection testing and much more, the American Society of Mechanical Engineers ASME has developed standards that apply specifically to these types of devices. This new standard applies to all new product manufactured after January 16, and does not require that existing below the hook lifting devices be reworked to adhere to the new standard requirements.

The label should include cautionary language to provide danger, warning, or caution notice to operators and others against a exceeding the rated load, or lifting loads not specified in the instruction manual b operating a damaged or malfunctioning unit, or a unit with missing parts c lifting people d lifting suspended loads over people e leaving suspended loads unattended f removing or obscuring warning labels g operating without having read and understood the operating manual h not staying clear of the suspended load i lifting loads higher than necessary j making alterations to lifter 2 Where size or shape of the lifter prohibits the inclusion of all or any such markings, a label shall be affixed, referring user to consult manufacturers instruction manual for product safety information. Each control shall be clearly marked describing resulting motion or function of the lifter. Chapter applies to the classification, marking, construction, installation, inspection, testing, maintenance, and operation of structural and mechanical lifting devices. The rated load of the lifting device shall be legibly marked on its main structure or on a tag attached to its main structure where it is visible. If the lifting device is made up of several lifters, each detachable from the group, these lifters shall also be marked with their individual rated loads. All new structural and mechanical lifting devices shall be marked with, but not limited to, the following information: 1 manufacturers name and address 2 serial number 3 lifter weight, if over lb 45 kg 4 cold current amps when applicable 5 rated voltage when applicable 6 rated load [as described in para. All repaired or altered structural and mechanical lifters shall be provided with identification displaying, but not limited to, the following information: 1 name and address of the repairer or alterer 2 repairers or alterers unit identification 3 lifter weight if altered 4 cold current amps if altered 5 rated voltage if altered 6 rated load if altered [as described in para.

If the listing device is made up of several lifters, each detachable from the group, these lifters shall also be marked with their individual rated loads. A lifter shall be designed to withstand the forces imposed by its rated load with a minimum design factor of 3, based on yield strength, for the load-bearing structural components.
