OPERATING PRACTICES - ASME B30.9 LOAD CONTROL 15

WHENEVER ANY SLING IS USED, THE FOLLOWING PRACTICES SHALL BEOBSERVED.

1. SLINGS THAT ARE DAMAGED OR DEFECTIVE SHALL NOT BE USED.2. SLINGS SHALL NOT BE SHORTENED OR LENGTHENED BY KNOTTING

OR TWISTING.3. SLING LEGS SHALL NOT BE KINKED.4. THE RATED LOAD OF THE SLING SHALL NOT BE EXCEEDED.5. SLINGS USED IN A BASKET HITCH SHALL HAVE THE LOADS

BALANCED TO PREVENT SLIPPAGE.6. SLINGS SHALL BE SECURELY ATTACHED TO THEIR LOAD.7. SLINGS SHALL BE PROTECTED FROM EDGES, CORNERS,

PROTRUSIONS AND ABRASIVE SURFACES TO PREVENT SLINGDAMAGE.

8. DURING LIFTING, WITH OR WITHOUT LOAD, PERSONNEL SHALL BEALERT FOR POSSIBLE SNAGGING.

9. ALL EMPLOYEES SHALL BE KEPT CLEAR OF LOADS ABOUT TO BELIFTED AND OR SUSPENDED LOADS.

10. HANDS OR FINGERS SHALL NOT BE PLACED BETWEEN THE SLING AND ITS LOAD WHILE THE SLING IS BEING TIGHTENED AROUND THELOAD.

11. SHOCK LOADING SHOULD BE AVOIDED.12. A SLING SHALL NOT BE PULLED FROM UNDER A LOAD WHEN THE

LOAD IS RESTING ON THE SLING.

INSPECTION: EACH DAY BEFORE BEING USED, THE SLING AND ALLFASTENINGS AND ATTACHMENTS SHALL BE INSPECTED FOR DAMAGE OR DEFECTS BY A COMPETENT PERSON DESIGNATED BY THE EMPLOYER.ADDITIONAL INSPECTIONS SHALL BE PERFORMED DURING SLING USEWHERE SERVICE CONDITIONS WARRANT. DAMAGED OR DEFECTIVESLINGS SHALL BE IMMEDIATELY REMOVED FROM SERVICE.

WORKING WITH BLOCKS 2

OVERHAUL WEIGHT

To determine the weight of the

block or overhaul ball that is

required to free fall the block,

the following information is

needed: Size of wire rope,

Number of line parts,

Type of sheave bearing,

Length of crane boom,

and Drum Friction.

BLOCK REAVING

Straight laced reeving is a basic method

of placing the rope through a set of

blocks. The end of the rope is fed

through the outside sheave of the

upper block to the outside sheave

of the lower (traveling) block. This

continues to the last sheave.

ADVANTAGES:

1. Allows blocks to

run closer together.

2. Is simple.

3. Has no reverse

bends.

DRAWBACKS:

Tilting because of

imbalanced loading

can cause block

rotation and wear

of the sheaves and

wire rope

SYMMETRICAL REEVING

Reeve blocks symmetrically to distribute

load evenly. All sheaves must be reeved

to achieve the full working load limit of

the block.

BLOCK CABLING

1. Reduce wire rope length

2. Use even part reeving

3. Dead end to boom

4. Evaluate wire rope construction

BLOCK HOOK INSPECTION 10

CROSBY RECOMMENDS AS A MINIMUM:

1. A visual inspection for cracks, nicks, wear, gouges and

deformation as part of a comprehensive documented

inspection program, should be conducted by trained

personnel in compliance with the schedule i B30.10.

2. For hooks used in frequent load cycles or pulsating load,

or exposed to corrosive conditions (Road Salt, etc.) the

hook and thread should be periodically inspected by Magnetic

Particle or Dye Penetrant.

LUBRICATION OF HOOK BEARINGS:

Anti Friction — Every 14 days for frequent swiveling; every

45 days for infrequent swiveling.

Bronze Thrust Bushing or No Bearing — Every 16 hours

for frequent swiveling; every 21 days for infrequent swiveling

ASME B30.10 INSPECTION FREQUENCY

1. Frequent Inspection - vi su al exa minations by the operator or
