Tcrack Three Core Technologies

This is Tcrack’s most critical functional advantage. When the cantilever arms are 100% fully extended beyond the base, there is no overhead obstruction above the stored materials.

This enables the factory’s overhead crane to lift materials directly from above, completely eliminating forklift dependency and achieving “aerial logistics.”

▲ Overhead crane lifting long materials from fully extended cantilever level — demonstrating zero overhead obstruction at 100% extension

▲ Rows of Tcrack telescopic racks — narrow aisle design dramatically optimizes vertical storage space

Since forklift access is no longer required, aisle width no longer needs 4–6m for forklift turning radius — only 1–1.5m for personnel/lifting equipment passage.

🚫 Red Line 1: Never Overload

Strictly adhere to the rated load on each cantilever arm nameplate. Chronic overloading causes irreversible plastic deformation of arms, damages bearing housing structures, and leads to gear-rack meshing failure.

Compliance Reference: OSHA 1926.250(a)(2)

🚫 Red Line 2: Never Extend Multiple Levels Simultaneously

Absolutely prohibited to extend two or more loaded cantilever levels at the same time. Multiple loaded levels extending simultaneously causes a dramatic forward shift in the center of gravity, generating tipping moments that exceed anchor bolt pull-out resistance.

Premium models feature interlock devices to physically prevent multi-level extension

🚫 Red Line 3: No Personnel Under or On Extended Arms

No personnel allowed beneath extended arms. Never stand on cantilever arms for inventory counting or any operation. Prevents injury from falling materials or unexpected arm retraction due to mechanical failure.

Compliance Reference: OSHA 1910.176
