They are used in various storage and handling applications, in the manufacture of single-purpose machines and inter-operating conveyors. The base is a rail fitted with a roller or pulley of various designs and load capacities. When ordering rails, it is necessary to specify the designation according to the type of rollers, the roller pitch and the required length of the rail.
The load must be in contact with at least three rollers to ensure the stability of the items being transported. When selecting the correct rail, it is therefore important to ensure the appropriate axial distance (spacing) between the centres of the rollers. Other parameters are the dimensions, weight and type of object to be transported.
Lightweight pulley rails are an important element in kanban, FIFO, LIFO systems where they are used as drop racks. They can also serve as guide rails for conveyor systems or simple non-powered conveyors. They are used as packing tables and picking stations. Their small size makes them suitable for transporting lightweight items such as cardboard boxes, KLT boxes, picking and storage containers.
Universal pulley rails find use in many different applications in material handling, warehousing and other technology, in storage systems as drop racks, guide rails and lateral guides, or as a connecting element of conveyors. The rails are available in many variants depending on the pulley design: with or without a hub, with plain or ball bearing, plastic, steel, thermoplastic rubber coated, PU coated or with brush pulleys.
Thanks to special pulleys, omnidirectional pulley rails allow movement in different directions and are therefore used for handling plastic boxes, cardboard boxes and other objects with a flat seating surface that need to be sorted and rotated.
Pallet rails are used for transporting pallets in both longitudinal and transverse positions. The rails are of solid construction, the U-profile is sufficiently resistant to twisting and deflection. The rollers are available with or without a hub and with a load capacity of up to 160 kg per roller. The rails can be supplied with accessories for loading pallets from forklift trucks - loading ramps and reinforcements, brakes, safety barriers or plates with ball units that serve as right-angled sliders.
One variant is the Groovy rails, which have wider rollers than standard rails. Heavy-duty slats are designed for extra heavy loads, with a load capacity of up to 1,000 kg per roller.
