When a pallet has to be transported lengthwise, a roller conveyor should be used as a rule. The pallet roller conveyor is standard structured from galvanized steel rollers of 88.9 mm diameter. The thickness of the steel is 2.9 mm. The actuation takes place by mutually linking the rollers with each other using separate chains. Every roller is fitted with two gear wheels on one side. Rollers of different sizes may be used (diameter 60-108 mm, steel thickness 2 to 3.25 mm). As illustrated, the rollers can be fitted with guide collars in the centre or on the side.
