Product Description

OVERVIEW

• The Outrigger Pad is a 24”x24”x2” base pad for ProStack 24"x6"x6" Cribbing Blocks. 

• The machined into the Outrigger Pad meshes with the pyramid pattern molded into the ProStack

  Blocks to create a stable,fully interlocked cribbing setup.

• WHEN LEVEL, 1-4 layers of ProStack Cribbing Blocks can be safely stacked to meet your height needs. 

CRIBBING BLOCK GENERAL GUIDELINES & FAQ'S

Stacking 

• ProStack Cribbing is designed to be stacked.

• The height to which the cribbing can be stacked is subject to the cribbing being used and the situation.

• Medium duty 24"x6"x6" ProStack cribbing blocks in ideal conditions should not be stacked higher

  than 3' without evaluation by trained and experienced personnel under the direction of a

  qualified technician or engineer trained in cribbing applications and safety.

• ProStack cribbing is designed to create a solid stack (without gaps). This type of set-up

  maximizes surface area contact, stability and support.

• The Army Core of Engineers recommends limiting (wood box crib) configurations to three

  times width (Shortest width for Non-Square Cribs).

• Box cribs: The standard is a 4x4 box crib with four contact points. Other configurations

  are shown in the Army Corps of Engineer diagrams.

• Height is always subject to the situation.

  
  

Guidelines  

• Be certain that the ground, floor, or other surface is capable of supporting the combined weight of the crib

  structure and the load to be supported.Never build cribbing on loose or unstable ground.

• Never exceed the maximum capacity of the cribbing.

• A-Frame Outriggers/Stabilizers: Take special precautions when deploying A-frame outriggers onto any

  cribbing set-up.Lateral forces need to be accounted for to avoid potential toppling of the set-up.

• ProStack cribbing should be constructed by trained and experienced personnel under the direction

  of a qualified technician or engineer trained in cribbing applications and safety.

• Do not use cribbing if it is cracked, split, warped, or damaged.

• Never use chemically damaged cribbing.

• Do not allow personnel to climb or hang onto cribbing.

• Whenever possible, avoid intermixing wood, metal, or other forms of cribbing with plastic cribbing.

• Ideal Conditions:

• The surface is flat and Level and fully capable of supporting the load and pressures.

• The load exerted onto the cribbing set-up is vertical.

Can ProStack Pyramid Interlocking Cribbing Blocks be used without using a Xinxing Base Pad?

• Yes, ProStack Cribbing Blocks can be used without a Xinxing Base Pad.

• Refer to the General Guidelines.

• Refer to the Xinxing ProStack Cribbing Situational Height Considerations.

• The purpose of the Xinxing Base Pads is to:

• Allow for full contact between the cribbing blocks and the base pad to reduce contact pressure.

• Allow for a fully interlocked solution, and eliminate any opportunity for lateral movement at the

  contact point between the cribbing blocks and the supporting surface.

• Prevent damage to the pyramids due to highly concentrated pressure.

• The height of the stack created should be evaluated by trained and experienced personnel

  under the direction of a qualified technician or engineer trained in cribbing application safety.

• Use of a Neoprene pad or other soft squish-able material that will not crush under high pressure

  is recommended to prevent damage to the interlocking pyramids and increase friction

  between the cribbing blocks and the surface they are placed on.

Can ProStack Cribbing Blocks be used without a neoprene pad being placed between the 

load contact point and the top cribbing block or block?

• Yes, ProStack Cribbing Blocks can be used without a Neoprene Friction Pad placed between

  the load contact point and the cribbing blocks.

• The purpose of the Neoprene Friction Pad being placed between the load contact point and

  the cribbing blocks is to:

• Increase friction between the two points and further minimize the chances of lateral movement.

• Prevent damage to the pyramids due to highly concentrated pressure.

• If a neoprene pad is not available, look to use other soft, squish-able materials that will not crush

  under high pressures.

  Plywood of an adequate condition and thickness could be an option in this case.

• Cribbing set-ups should be evaluated by trained and experienced personnel under the direction

  of a qualified technician or engineer trained in cribbing application safety.
