The SLZ-T universal stacker is the core equipment in the intelligent three-dimensional storage system, and it has two types: single-extension and double-extension. It is suitable for working scenarios where pallets are used as storage units in various industries such as tobacco, alcohol, food, medicine, machinery, chemical industry, lithium battery and new energy. This product has high safety and reliability, and is equipped with a variety of safety protection measures such as anti-breakout, anti-tipping, anti-top-impact, anti-pier bottom, anti-rope break, anti-overload, anti-fall, and anti-tangled ropes. It can realize functions such as automatic inventory counting, cargo position scanning, and visual positioning. In application scenarios above 15 meters, the upper and lower synchronous drive closed-loop control is used to effectively reduce the swing amplitude of the equipment during the start-stop stage, which is conducive to the fastest stabilization of the system and determination of the cargo position, and complete the storage and retrieval actions.
