Section 5.1 Purpose
|
| 5.1.1 |
The purpose of this chapter is to provide guidelines of webbing sling preparation, inspection and use. |
| |
Section 5.2 Mechanical Considerations
|
| 5.2.1 |
Determine weight of the load. The weight of the load shall be within the rated capacity of the sling. |
| 5.2.2 |
Select sling having suitable characteristics for the type of load, hitch and environment. |
| 5.2.3 |
Slings shall not be loaded in excess of the rated capacity. Consideration should be given to the angle of lift, (sling to load angle) which affects rated capacity. |
| 5.2.4 |
Slings with fittings which are used in a chocker hitch shall be of sufficient length to assure that the choking action is on the webbing, and never on the other fitting. |
| 5.2.5 |
Slings used in a basket hitch shall have the load balanced to prevent slippage. |
| 5.2.6 |
The opening in fittings shall be the proper shape and size to insure that the fitting will seat properly in the hook or other attachments. |
| 5.2.7 |
Slings shall be protected from contact with edges, protrusions or abrasive surfaces. |
| 5.2.8 |
Slings shall not be dragged on the floor or over an abrasive surfaces. |
| 5.2.9 |
Slings shall not be pulled from under loads when the load is resting on the sling. |
| 5.2.10 |
Slings shall not be pulled from under loads when the load is resting on the sling. |
| 5.2.11 |
Do not drop slings equipped with metal fittings. |
| 5.2.12 |
Slings that appear to be damaged shall not be used unless inspected and accepted as usable under Section 5.2. |
| 5.2.13 |
The sling shall be hitched in a manner providing control of the load. |
| 5.2.14 |
Portions of the human body should be kept from between the sling and the load, and from between the sling and the crane hook or hoist hook. |
| 5.2.15 |
Personnel should stand clear of the suspended load. |
| 5.2.16 |
Personnel shall not ride the sling. |
| 5.2.17 |
Shock loading should be avoided. |
| 5.2.18 |
Twisting the legs (branches) shall be avoided. |
| 5.2.19 |
Load applied to the hook should be centered in the base (bowl) of hook to prevent point loading on the hook. |
| 5.2.20 |
During lifting, with or without the load, personnel shall be alert for possible snagging. |
| 5.2.21 |
The slings’ legs (branches) should contain or support the load from the sides above the center of gravity when using a basket hitch. |
| 5.2.22 |
Slings shall be long enough so that the rated load (rated capacity) is adequate when the angle of the legs (branches) is taken into consideration. |
