DURA CRIB® COG & STEP CHOCK COMBO incorporates a small crib fast step chock and an incline wedge with lanyard. The function of the cog and step chock is based on the design and function of a cog incline railroad. This feature provides incremental positive locking as the cog moves up the step chock.
* Total Block Working Load Limit (WLL) is based on a full press load evenly distributed across the top and bottom surfaces of the cribbing block.
Warning: Always perform your own risk assessment before using this product. Always know the weight of the equipment or machine being supported. Consult your equipment and machinery manufacturer manual and guidelines for recommended blocking and lifting points. Never exceed the maximum WLL of the cribbing blocks or cribs. Under no circumstances does the WLL mentioned above take into consideration point loading or uneven weight distribution of the supported load.
