J-CRIB Pumpable Crib is a specialized pumpable cement and containment bag that replaces conventional timber cribs in longwall tailgates and bleeder headings.
An important benefit J-Crib supports is its significant residual load performance in high convergence areas. This feature will aid in the stopping performance in high deformation areas for a more secure ventilation infrastructure.
J-Latch is designed to replace conventional timber cribs (4- and 9-point). Timbers are interlocked and there is 100% contact which greatly improves strength and stability, and also allows for higher aspect ratios.
J-PAK Cribs are a standing support product that utilizes a custom-made steel shell filled with specialized cement. J-PAK is designed to slowly yield under rock load.
