Frequently Asked Questions

What is a vertical lift in a warehouse?
A vertical lift is an automated elevator that moves pallets, cases, cartons or totes between levels of a racking system, mezzanine or ASRS, transferring loads onto and off conveyors at each level. Addverb's vertical lifts include a pallet lift and a carton lift, both built with integrated safety sensors and precise motion control. They connect storage levels to conveyors and goods-to-person stations. -
What is the difference between a pallet lift and a carton lift?
A pallet lift moves full pallets between levels, while a carton lift moves lighter cases, cartons and totes at higher speed for picking and replenishment flows. Addverb's pallet lift carries loads up to 1,500 kg with a load area up to 2,200 x 1,800 mm at up to 0.9 m/s. The carton lift serves tote and carton ASRS, feeding conveyors and goods-to-person stations. -
How high can a vertical lift go, and how much space does it need?
Addverb's vertical lifts can be customised to heights of up to 20 m, and the pallet lift needs an installation area of about 2,800 x 2,400 mm with a 500 mm infeed and outfeed height. Chain and roller conveyor attachments connect the lift to surrounding lines. Lift height, speed and count are sized together with the storage system, since lifts often set peak throughput. -
What safety features does a vertical lift include, and can it run in cold storage?
Addverb's vertical lifts include limit switches, an emergency stop, an overspeed governor, a safety brake and bumpers, and they carry CE certification for compliance with industry safety standards. The pallet lift operates from -25 °C to +40 °C, so it can serve freezer and chilled ASRS as well as ambient warehouses. Automated lifting removes the need for forklifts or people to move loads between levels. -
When can a vertical lift become a bottleneck?
A vertical lift becomes a bottleneck when every load entering or leaving a multi-level system must pass through it, because each lift handles one load or batch per cycle while shuttles on many levels work in parallel. Addverb sizes the number, speed and placement of lifts against peak inbound and outbound rates during design.
