Does Osha Require Outrigger Pads?

According to OSHA, safety is always a requirement. OSHA 1926.1402 states that, in all instances in which a crane or other lifting equipment is used, the ground on which the equipment is placed must be firm, sufficiently drained, properly graded, and able to support blocking, cribbing, and outrigger pads.

Are outrigger pads required?

Posted in Worksite Safety. An outrigger pad is a safety tool that can be used with any equipment that has outriggers, down jacks or stabilizers. It is a must for stability when a piece of equipment – such as a crane – lifts loads or personnel aloft.

Are crane outrigger pads required?

Some believe setting up on concrete or asphalt would be safe and you may not need outrigger pads. However, it is recommended to always use outrigger pads under crane floats to distribute ground pressure just in case there is an open cavity or unseen voids,” says Billy Smith EVP of Claims and Risk Management of NBIS.

Do cranes need to be setup on solid level ground?

You must not assemble or use a crane unless ground conditions are firm, drained, and graded to a sufficient extent so that, in conjunction (if necessary) with the use of supporting materials (such as blocking, mats, cribbing, or marsh buggies (in marshes/wetlands), the equipment manufacturer’s specifications for

What is the purpose of outrigger pads?

The outrigger pad is used to displace the point of contact pressure PSI/ PSF that the ground sees. The outrigger pad expands & displaces the point of contact from the equipment’s outrigger/ pontoon/ shoe/ float. This will decrease the PSI or PSF for the GBC ( ground bearing capacity).

How is outrigger load calculated?

Simply divide the maximum outrigger load by the allowable ground bearing pressure to determine the pad area you need. Example: Maximum outrigger load = 100,000 lbs. Allowable ground bearing pressure = 3,500 psf. (100,000 lbs / 3,500 psf = 29 ft² of area).

When must crane inspections take place OSHA?

OSHA regulations only require that such equipment be inspected during initial use and annually thereafter by a “competent person”, or by a government or private agency recognized by the U.S. Department of Labor. The owner must, also, maintain a record of these inspections.

What guidelines should you follow when using a crane with outriggers?

• If a crane has outriggers they should be used on every lift.
• All outriggers on a crane must be used if an outrigger load chart is being used for calculating load capacities.
• Even on ideal, solid ground always use outrigger floats or mats.
• Use of a crane’s outriggers is your choice.

What is span blocking on a crane?

Blocking (also referred to as “cribbing”) is wood or other material used to support equipment or a component and distribute loads to the ground. It is typically used to support lattice boom sections during assembly/disassembly and under outrigger and stabilizer floats.

What is the minimum size of wire rope allowed for lifting personnel?

All sheaves used in the boom hoist reeving system must have a rope pitch diameter of not less than 18 times the nominal diameter of the rope used. The operating design factor for the boom hoist reeving system must be not less than five.

What must be done before operating a crane OSHA?

The operator must begin hoisting the load to determine, using a load weighing device, load moment indicator, rated capacity indicator, or rated capacity limiter, if it exceeds 75 percent of the maximum rated capacity at the longest radius that will be used during the lift operation.

What does OSHA consider a crane?

Definitions applicable to this section. A crane is a machine for lifting and lowering a load and moving it horizontally, with the hoisting mechanism an integral part of the machine. Cranes whether fixed or mobile are driven manually or by power.

What must be done before operating a crane?

Visually inspect the crane before use. Make sure all loose materials, parts, blocking and packing have been removed from the load before lifting. Remove any slack from the sling and hoisting ropes before lifting the load. Make sure that the lifting device seats in the saddle of the hook.

What are outrigger pads made of?

polyethylene
Industrial plastic outrigger pads, like the ones engineered here at Cope Plastics, are made from an extremely tough polymer called UHMW (ultra high molecular weight) polyethylene. There are several reasons why UHMW outrigger pads outperform those made of hardwood.

What is the purpose of placing mats or cribbing under outrigger floats?

What is the purpose of placing mats or cribbing under or cribbing under outrigger floats? Distribute the force over a larger area. Where is the best location for leveling a crane?

What are crane pads made of?

The crane outrigger pads are made of Fiber-Reinforced Polymer (FRP). This is a composite material made of a vinylester polymer that is reinforced with specially designed fiberglass.

How do you measure outrigger pads?

Crane mat size can be calculated by dividing the crane load by the maximum permissible ground pressure. Not only do crane mats used for distribute outrigger loads need to be suitably sized they also need to be strong to withstand the load imposed by the crane outriggers.

What is crane outrigger?

Outrigger: A beam which extends from the lower works of a crane to increase the crane’s stability. The beams may be either extendible/retractible or fixed length and typically utilize some type of pad to distribute loads to the ground surface. ( Source: A Glossary of Common Crane and Rigging Terms.

What must you know when using a load chart?

The load charts are specific to the make, model and configuration of a specific piece of equipment. Don’t forget to include adjustments for buckets, boom extensions, load blocks, hoisting rope and other attachments that will alter the lifting capacity of the crane or equipment used to perform the lift.

Are inspections required by OSHA?

Normally, OSHA conducts inspections without advance notice. Employers have the right to require compliance officers to obtain an inspection warrant before entering the worksite. During the walkaround, compliance officers may point out some apparent violations that can be corrected immediately.

Does OSHA require daily equipment inspection?

Daily, pre-shift inspection of powered industrial trucks is required by OSHA standards.
