DICA has received a patent for its ProStack Slot Lock Interlocking Cribbing Blocks. Issued in late 2022, the patent (U.S. Patent 11,479,939), is for the slot and flange interlocking system. Each block has a flat lower surface with downward extending lips positioned at opposing ends of the lower surface. When the blocks are stacked and pressure is applied, the blocks lock together, giving users the ability to safely gain cribbing height in unlevel conditions.
“Slot Lock Cribbing Blocks can be used under medium sized equipment with stabilizer or outrigger reaction forces up to 100,000 lbs. such as aerial lifts, digger derricks, concrete pump trucks, knuckle boom cranes,” said Kris Koberg, CEO of DICA.
The interlocking system can be used independently or integrated with slotted SafetyTech Outrigger Pads to increase bearing area and decrease ground bearing pressures. Each layer used increases cribbing height by five inches. “The combination of variable height, interlocking stack ability, and compatibility with SafetyTech Outrigger Pads gives operators the safety, stability, and versatility needed when working in unlevel environments,” said Koberg.
The cribbing blocks are purposefully made from a combination of post-consumer and post-industrial recycled material. This material mixture provides users with a long lasting and environmentally friendly solution that won’t splinter, crack, or rot.
