Types of warehouse picking trolleys include push carts, shopping carts, multi-layered carts and multi-handled carts. The trolleys may have specific features such as steps or ladders, cages, tilts for display or removable bins. They can be made of wood, steel or plastic, and be automated or adjustable. New picking trolleys generally cost between $300 and $700 as of 2015.
The primary purpose of a picking trolley is to serve as the central transportation unit for a warehouse. It should be chosen as much for the items being moved around as for the layout of the warehouse. Ideally, picking trolleys improve a number of different aspects of warehouse work. They reduce lost time, reduce worker fatigue, produce warehouse data, help the business scale for growth, integrate into any picking style and increase accuracy.
Order picking is a fundamental operation in warehouse supply chain management. There are a number of different methods of picking including piece picking, in which workers are measured on pieces picked per hour; zone picking, where workers focus on specific warehouse zones; and wave picking, when workers pick objects in large sequential waves. The effectiveness of picking greatly impacts productivity.
Other important warehouse technologies include conveyors, forklift trucks, cranes, racking or shelving, lifting platforms and computer sorting software.
