DIFFERENT CONDITIONS MAY SUGGEST DIFFERENT INTERVALS.

Class Description Typical Schedule


New Cranes:

Prior to initial use, cranes must be tested and inspected

completely using the criteria applicable to periodic

inspections. A report should be kept on file for future

reference.



Idle Cranes:

Cranes that have been idle for a period that exceeds six

months must be inspected and tested before being

placed back in service using the criteria that applies to

periodic inspection. Special attention should be given to

the hook, lifting chain and wire rope.



Altered Cranes:

All cranes that have been extensively altered or repaired

must be completely inspected and tested. If load

sustaining parts have been altered or repaired, then a

load test should be conducted to verify the rated load

capacity of the crane. A report should be issued by a

qualified person and kept on file for future reference.



Load Testing a New Crane:

New and rebuilt hoist are load tested by the manufacturer at the factory. Most manufacturers will furnish load test certificates for a nominal charge.



Load Testing a Used Crane:

When load testing a used crane, the test load cannot exceed 125 percent of the rated load unless otherwise recommended by the manufacturer. The hoist, trolley and crane should be operated a number of times at various positions. The test load should be transported by the trolley and bridge over the full length of the crane. A report should be issued by the testing organization giving the conditions under which the system was load tested.



Preventive Maintenance Should Cover:

1. Cleaning and lubricating the wire rope (cable) and load chain.2. Adjusting the brakes.3. Checking and filling the gear cases to the proper levels.4. Replacing any contaminated oils.5. Lubricating the bearings, gears, pinions, linkages, shafts, etc.6. Adjusting the operation of limit switches.7. Cleaning or replacing pitted or burned electrical contacts.8. Cleaning or replacing the air and fluid filters.9. Inspecting the operation of all controls and warning systems.



Preoperational Tests - General:

1. Ensure all emergency disconnects are known before any test.2. If you’re not familiar with the cranes’ operation get help.3. Ensure that the manufacturers recommendations are followed.4. If you have a checklist - follow it! 5. Inspect all electrical controls for proper operation.6. Check for obstructions in the travel path of the crane.7. Test all controls to determine proper operation.8. Observe for smooth operation of the components.9. Never unwind the spool completely!10. Check upper and lower limit switches.



Preoperational Tests - Hooks:

1. Replace if deformation or cracks are found.2. Check for proper function of the safety latch.3. Inspect for twists from the plane of the unbent hook.4. Check for proper swivel.5. Hook repair is generally not recommended. 6. Emergency hook repair must be performed only under

competent supervision.7. After any hook repairs, the hook must be load tested before

being returned to normal service.



Preoperational Tests - Rope:

1. Reduction in rope diameter (replace if found).

2. Broken or worn outside wires.

3. Corroded or broken wires at end of connections.

4. Severe kinking, crushing, cutting or unstranding.

5. Corroded, cracked, bent, worn, or improperly applied end

connections.



Lock-Out Tag-Out Considerations:

1. Review requirements for the individual crane.

2. Integrate lock out and maintenance requirements.

3. Ensure training in adequate for level of maintenance.

4. Ensure written programs are established and reviewed.

5. Carefully select lockout devices, ask the manufacturer for

recommendations.

6. Do not necessarily assume devices are interchangeable

between different types of cranes.

Lifting operations are inherently dangerous. Even when proper training is conducted, Equipment is properly maintained, Employees conduct themselves in a safe manner, and other facets of the safety program are conscientiously attended to, accidents can still occur. The reason is that crane operations are primarily dependant on mechanical devices. These devices can and do fail. When this happens during a lifting event the results can be catastrophic. You are the only controlling influence that can minimize the hazard. Your life literally is in your own hands!


Physical and Mental Requirements of Operators:

No history of unsafe acts in the workplace. Have a mature and safe attitude at all times. The ability to react quickly in an emergency. Drug and alcohol free during any lifting event. Good depth perception (essential for load spotting). Good hearing and vision (corrected or uncorrected). Be thoroughly trained in all facets of the required lift. Understand the requirements for all phases of the lift. Taking no medication that will interfere with the operation.



Safe Practices for Operators:

Test all hoist controls and brakes at the beginning of each shift.

Never attempt to operate a crane or hoist that is suspected to be unsafe.

Always test brakes by a short lift to ensure control.

Move loads only after being signaled by the designated, qualified signaler.

Safe Practices for Operators (continued)

Never carry loads over workers. Never carry loads past workers (they must yield right of way). Signalers must keep line-of-sight with the operator. Never allow riders on loads or hooks. Never allow unauthorized persons to operate cranes. Always lockout before maintenance or repairing cranes. Frequently inspect cranes exposed to adverse conditions.


Safe Practices for Operators (continued)

Always position the hook directly over the load before lifting the load off of the floor.

Document and maintain inspection records. Check warning devices and signals before use. Signalers must watch the load. Operators must watch the signalers. Know your travel path in advance of the lift! Know where you’re going to set the load down! Will the new location support the weight?


Safe Practices for Signalers

Only one person is the designated signaler.

Maintain line-of-sight with the operator.

Ensure the operator acknowledges every signal.

Stop the operation if comprehension is lost.

Operators must watch the signalers.

Plan in advance where the load is going!

Know the new location will support the weight.


Leaving or Parking Hoists or Cranes

Raise all hooks to - but not through - limit switches. Place all controls in the “off” position. Place main power switch in the “off” position. Make a visual check for any dangerous condition. Report any defects immediately. Tag out defective equipment immediately. Report all cranes that are not in operation immediately. Follow the manufacturer’s recommendations.


Lifting Factors

Size, Weight, and Center of Gravity of the Load. The Number of Sling Legs. The Angle the Sling Makes With the Horizontal Line. The Rated Capacity of the Sling. The History of the Care and Usage of the Sling.

HANDLING THE LOAD

Lifting Factors

Size, Weight, and Center of Gravity of the Load.

To make a level lift, the crane hook must be directly above the center of gravity point. If the crane hook is too far to one side of the center of gravity, dangerous tilting and unequal stress to the sling leg will result.

HANDLING THE LOAD

Lifting Factors

Number of Legs and Angle with the Horizontal.

As the angle formed by the sling leg and the horizontal line decreases, the rated capacity of the sling also decreases.

HANDLING THE LOAD

1000lb 1000lb 1000lb

Lifting Factors

Rated Capacity of the Sling.

The rated capacity varies depending upon the type of the sling, the size of the sling, and type of hitch. Consult with the manufacturer. Also, older slings must be used with additional caution. Sling charts are generally based on new sling usage.

HANDLING THE LOAD

Lifting Factors

History of Care and Usage.

Mishandling and misuse of sling are the leading cause of sling-related accidents. Proper care is essential for maximum service and safety.

Always protect slings with cover saddles, burlap padding or wood blocking to prevent sharp bends and cutting edges.

HANDLING THE LOAD

Estimating Weight of Load

Use a Dynamometer. Check shipping papers. Check nomenclature plates. Use industry standard tables or charts. Consult with the equipment manufacturer. Estimate weight using weights of similar loads. Never attempt a load lift based solely on a guess! Stay within 50% of the cranes rated capacity when

estimating loads (or manufacturer recommendation).

HANDLING THE LOAD

Types of Rigging and Slings

Chains. Wire Rope. Fiber Rope. Synthetic Web. Cargo Nets.

HANDLING THE LOAD

EACH TYPE HAS ADVANTAGES AND DISADVANTAGES!

Types of Rigging and Slings

HANDLING THE LOAD

Consult with the sling manufacturer concerning load capacities, usage methods, restrictions and other pertinent data for specific types of slings.

Working Rules for Slings

Never load in excess of the rated capacity. Never use a sling that is damaged in any way. Never pull a sling from a suspended load under tension. Never shorten with knots, bolts or other makeshift devices. Always keep suspended loads clear of employees. Always keep suspended loads clear of all obstructions. Always keep hands and fingers clear of untensioned loads. Always pad or protect slings from sharp edges of the load. Always think before you affect a load.

HANDLING THE LOAD

Inspection Procedures for Wire Rope Slings

Remove from service if you find:

HANDLING THE LOAD

1. Ten randomly distributed broken wires in one lay.2. Five broken wires in one strand in one lay.3. Kinking, crushing, bird caging or any other damage.4. Evidence of heat damage.5. Any end attachments cracked, deformed or worn.6. Hooks that have been opened more than 15% of the

normal throat opening or twisted more than 10% from the plane of the unbent hook.

Inspection Procedures for Alloy Steel Chain Slings


HANDLING THE LOAD

1. Defective or questionable welds.2. Bending or elongation of chain links.3. Cracked or deformed master and coupling links.4. Missing or removed identification tags.5. Any end attachments cracked, deformed or worn.6. Any other reason to suspect an unsafe condition.

Inspection Procedures for Synthetic Web Slings


HANDLING THE LOAD

1. Acid or caustic burns.2. Age deterioration (drying out cracking etc.).3. Melting or charring of the sling surface.4. Snags, tears or cuts causing exposure of colored thread.5. Missing or removed identification tags.6. Any other reason to suspect an unsafe condition.

After the Lift is Completed:

Clean the sling. Check for damage. Follow proper storage rules. Leave in proper condition for the next lift. Don’t wait to report damaged or defective slings. Follow proper disposal or replacement procedures.

HANDLING THE LOAD

Storage Rules for Slings

Store Slings:

In a dry environment out of direct sunlight. Off of the floor or ground to prevent corrosion. Hung from hooks to prevent tangling and easy access. Away from electrical sources. By type - i.e. don’t mix steel chain slings with synthetics. In a controlled area.

HANDLING THE LOAD

Sling Angles:

Consult with the sling manufacturer concerning how sling angles affect load capacities for different types of slings.

HANDLING THE LOAD

1000lb 1000lb 1000lb

Sling Angles:

The angle the sling is hung affects the sling load capacity. The greater the sling angle the greater the stress. Multiple sling usage drastically affects load capacity. The type of sling used is a factor. Consult with the sling manufacturer for proper usage.

If slings are used as twin slings, the carrying capacity decreases as the spread between the slings increases. To determine the capacity of each sling in a bridle hitch:

1. Measure the distance along one sling for the same number of units as the capacity of the sling in tons (Distance A).

2. Measure the vertical distance from the point located in (1) to the load in tons. (Distance B).

3. The number of units in this vertical distance (B) is the working load for the sling.

A = 2 ft. (or any unit) (2 Ton Sling Capacity)B = 1.5 ft.

Working Capacity of Each Sling = 1.5 Tons

Note: The individual sling capacity must be more than half of the total load weight! Consult with the manufacturer for specific types of rigging arrangements

Sling Angles:

The angle the sling is hung affects the sling load capacity. The greater the sling angle the greater the stress. Multiple sling usage drastically affects load capacity. The type of sling used is a factor. Consult with the sling manufacturer for proper usage.
