Harvesting trolleys are designed for tomato and cucumber harvest into crates. The suspension system allows both rolling along the heating pipe system and free manoeuvring on the greenhouse connector. The WDZ series harvesting trolleys are made of zinc-plated steel and aluminium. They are hand operated. A WDZ-CZ harvesting trolley features aluminium wheel hubs. The carrying capacity of the trolley is 150 kg when fitted with five 15-kilo crates lined up in each of 2 rows.
