What design aspect is characteristic of a tiering truck?

A tiering truck is specifically designed to maximize storage density in warehouses and distribution centers. It does this primarily through the use of straddle arms, which allow the truck to reach and pick items from multiple shelves or tiers, often in narrow aisle configurations. The straddle arms provide stability and support while lifting and moving loads, making it easier to handle pallets stored in racking systems that have various heights.

This design enables the tiering truck to maneuver through tighter spaces while still being able to lift and place loads at different levels effectively, which is essential in environments where space optimization is crucial. Additionally, the attachment of straddle arms means it can securely hold pallets or containers as it operates, allowing for both safe transport and precision placement within the storage area. This functionality distinguishes tiering trucks from other types of material handling equipment that may not have the same capability to operate in restricted areas or manage multi-height storage efficiently.
