Cable Hauled Conveyor Systems

JLV manufactures in its own factory the belt, pulleys and other components for cable hauled conveyor systems.

What is a Cable Hauled System?

Most people are familiar with conventional conveyor systems where the belt moves along idler rollers. In this system the driving and carrying mechanism is the rubber conveyor belt.

In a cable hauled conveyor system (cable belt) the driving and carrying mechanisms are separated. The driving forces are provided by two steel wire ropes (cables) and the material carrying medium is a rubber conveyor belt.

These ropes are supported by grooved pulleys at regular intervals along each length. The belt rests on the ropes and is retained thereon by of two pairs of "shoeforms". Each shoeform has two triangular legs, which together form a vee shaped groove, this engages and grips the underlying rope. The belt has carry shoeforms moulded along the bottom cover and return shoeforms moulded along each edge of the top cover.

Since the ropes transport the belt, longitudinal tensions in the belt are relatively low (compared with conventional conveyor belts), nevertheless, some belt tension is necessary, to ensure that the belt lays flat along the ropes under all conditions.

The belt is sufficiently flexible in the longitudinal direction to negotiate head, tail and tension drums, yet has sufficient transverse stiffness to support the load above the ropes. Belt support or troughing idler rollers are not required.
