Link-N-Lock® Roof Support System
The Link-N-Lock System is designed to improve mine safety by replacing
four and nine-point cribs in mine ceiling heights up to sixteen feet. It
is a support system of interlocking timber blocks stacked in layers. Their
interlocking capabilities create 100% contact between the layers, thereby
increasing strength and stability as the unit length increases.
Uses up to 50% Less Wood for the Same Support
The Link-N-Lock System is timber efficient, using 100% of the wood for roof support. Because it is so efficient, a crib built with Link-N-Lock uses up to 50% less wood for the same support strength as a four-point crib.
Each Link-N-Lock is smaller, lighter and easier to handle than conventional crib blocks, which results in significant savings in material handling, productivity, labor and transport, as well as reduction of lost time accidents. The unique interlocking mechanism provides added stability, allowing higher aspect ratios than conventional cribbing. The Link-N-Lock can be used with our line of PACKSETTER™ Pre-Stressing Devices or with wedges.
Like all Strata Products systems, the Link-N-Lock System is engineered using selected single specie timber. Coupled with our manufacturing process, this guarantees uniform size and predictable performance.
