DICA receives first patent for ProStack cribbing blocks
01 August 2023
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, the company said.
“Slot Lock Cribbing Blocks can be used under medium sized equipment with stabilizer or outrigger reaction forces up to 100,000 pounds such as aerial lifts, digger derricks, concrete pump trucks and knuckle boom cranes,” said Kris Koberg, CEO, 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,” Koberg added.
