This process explains why the results of Purdue University’s shock test on Pinned Plank were so remarkable. The strength of the block is greatly increased because the shock created by the falling weight is dispersed in multiple directions. The shock follows the directions of the wood grains as in a butcher block the multiple pieces of wood have the grains going in many directions. The weight to strength ratio of both PIN-LOK and PIN-LAM is multiplied greatly when components are locked together to build the pinned plank (COV, MOE, FB FV). Why does PIN-LAM & PIN-LOK hold up to a greater shock load? See the video for destructive testing to see the strength levels of Pinned products. Coupled with the continual locking down the length of plank, the mixing of the wood grains in each component, and using scaffold grade lumber we have developed the toughest and strongest wooden planks in the industry. Essentially each scaffold plank is comprised of multiple 2 foot plank sections. This causes a positive locking of all pieces every 2 feet to continually lock the boards together the full length of the plank. The locking pin is a spiral steel screw that forces its flanges deep into the undersize hole. The physics of pinning woods together is that the whole piece is being supported by every other piece in its place (load sharing). Why will PIN-LAM & PIN-LOK planks carry more weight than other types of scaffold plank? Planks can safely be cut back without sawing into a pin. The pin spacing down the full length of the plank is approximately every 2 feet but always 3 inches away from an even foot mark. What is the pin spacing for plank cut backs? The vertical LVL sandwiched between solid woods forms a traction strip down the full length of the plank. PIN-LAM uses Laminate wood orientated vertically for a center component, surrounded on both sides with solid scaffold woods, and all components solidly pin locked together. What materials are used in making PIN-LAM 2.2E? PIN-LOK is developed using scaffold grade woods of Select Structural (SS), Dense Select Structural (DSS), Machine Stress Rated (MSR 2400 to 2800) or Dense Industrial (DI65) materials.Īll these scaffolding woods are re-inspected using only materials that pass Indian Mill certification process to develop PIN-LOK scaffold Plank. What grade of material is PIN-LOK 2.0E manufactured from? The result of locking components together creates a finished product that has superior strength and improved shock resistance.īoth PIN-LOK and PIN-LAM planks are superior to any other wooden scaffold plank in safety and durability. In making a Pinned Plank smaller wooden components are solidly screw locked together to form a scaffold plank.
