Safety Information That You Need

At the heart of any effective safety program is a constant effort to ensure that employees have the proper knowledge and skill for all aspects of their job. Rigging and lifting clearly is an operation that has been shown to require knowledge and skills. Accidents also can harm your companies’ brand and reputation. Having a well-trained lift team can help mitigate, and possibly eliminate some of the hazards associated with using cranes. A safe lift depends on a number of people filling roles including operators, riggers, journeyman riggers, signal persons, crane owners, crane users, lift directors, supervisors, and the communication between those people.

B30.9-1.9.1-3 Slings shall be inspected by:

A qualified person as to whether it constitutes a hazard. And if so, what additional steps need to be taken to address the hazard and how it can be eliminated. And, shall have a thorough education, training, experience, skill and physical ability, as necessary, be competent and capable to perform the functions as determined by the employer or employer’s representative. Sling working load limits (WLL) are based on items being in acceptable condition before being used per ASME B30.9, OSHA 1910.184 and the manufacturer’s recommendations and limitations for use.

Working Load Limit (W.L.L)

The MAXIMUM load that shall be applied in direct tension to undamaged straight length of a sling or hoisting equipment.

hujiaozi 36

WLLS are based on the following factors:

  1. Type of hitch being used
  2. Material strength
  3. Design factor
  4. Angle of loading
  5. Diameter of the object (D/d)
  6. Manufacturer’s limitations

Minimum sling inspection intervals:

  1. Prior to each use
  2. Beginning of each shift
  3. Monthly to quarterly depending on severity of use by a designated competent person
  4. Annually by a dedicated, competent person

Vertical Plate Lifting Clamps

  1. Lift and turn over flat plate 180º or transport in the vertical position.
  2. For short plates one clamp can be used to lift.
  3. For long plates use a beam with vertical slings on each end connected to each clamp.
  4. Avoid lifting load 20% below the rated capacity of the side of the clamp.
  5. Select a clamp as close to the max loading as possible, this will insure full penetration of teeth into plate.
  6. Max surface 300 Brinell/32 RC. Do not lift plates harder than the teeth of clamp.

Tightening the Pin in a Screw Pin Shackle

ASME B30.26 has the following statement regarding screw pin shackles:
The screw pin threads shall be fully engaged and tight and the shoulder should be in contact with the shackle body.
Thus, contrary to popular belief, you should never back off the screw pin before use. The shackle pin should be a minimum of hand tight before the lift begins.

Safe Hoist and Crane Operations

Smooth, steady application of lifting force

  • Allows hoist and rigging to adjust to change
  • Minimizes spin
  • Reduces wear on wire and synthetic rope

NO Shock loading - A 4" DROP TRIPLES THE LOAD

MANUAL HOIST

NEVER WRAP THE CHAIN AROUND THE LOAD

THIS IS WHAT CAN HAPPEN IF YOU WRAP THE CHAIN AROUND THE LOAD
THESE HOISTS ARE ONLY MADE FOR A STRAIGHT PULL
