Flatbed trolleys have been used forever, to haul goods around. The old heavy wood units have been replaced by lightweight, sleek, easily manoeuvred trolleys.
Some handles fold down for ease of transporting. Some have six wheels instead of four. Some have large or pneumatic wheels for ease of manoeuverability.
Capacities range from 150 Kgs through to 500 Kgs, but can go higher.
Two and three tier trolleys enable goods to be stacked at different levels. Those levels may even have a short mesh surrounding them to prevent product from falling off.
Stockpicking trolleys can be supplied with picking bins and lecterns. Three sides can be of mesh, and any configuration or size can be catered for.
