I-Beam type hanger conveyors which are generally used in various industries where heavy services are required and sensible transportation is not needed are also very important in today’s technology. Apart from its robustness, it is also the preferred type of conveyor system because of its simple structure and less maintenance needs. It works on the basis of trolleys mounted on the chains moved by the drive units proceed along the NPI profiles to carry the hanger loads. The chains are also suitable along with vertical movements work on z axis in addition to the horizontal movements along x and y axes. Horizontal curves are produced in wheel and roller types in different sizes and angles, and the vertical curves are produced in diameters and angles that vary according to the trolley distances. The chains in these systems are composed of 3 pieces called side link, center link and pin which are made of forged high carbon steel. As the links of the chains are connected to each other without rivets, so that quite easy to assemble and disassemble. Trolleys are composed of 2 symmetrical bodies between which carrier flakes are connected and on which wheels are mounted. Rollers are special type conveyor ball bearings that can work up to 200°C. On the other hand, bodies are made of forged high carbon steel. Trolley ball bearing are lubricated by means of the greasing elements attached on the bodies. Drive units divide into two main groups; the first one is the caterpillar that moves along straight rails, and the second one is the angular type mounted on a curve rail. Caterpillar type drive groups have alternatives in stable and floating constructions with different powers. Similarly, the angular drive groups also have different types and powers such as stable and tension types on 90° or 180° curves.
  We have 3", 4" and 6" Webb type conveyor systems in our production schedule. The conveyor type to be used is determined considering the maximum unit load and the transportation lay-out. Connecting two trolleys with bars in all systems doubles the maximum unit load carrying capacity.

I-BEAM TYPE CONVEYORS:

3" (TR348) Conveyor Systems: These systems are so called because the chain pitches are very close to 3". The trolleys mounted on the chain can move on NPI 80 - 100 profiles. The unit load carrying capacities of the trolleys is 140 kg, the breaking off force of the chain is 11000 kg. As trolleys can only be connected to the middle links of the chains, their clearances can be determined as 6” and its powers.

4" (TR458) Conveyor Systems: These systems are so called because the chain pitches are very close to 4". The trolleys mounted on the chain can move on NPI 100 - 140 profiles. The unit load carrying capacities of the standard trolleys is 200 kg. and the breaking off force of the chain is 22000 kg. Unit loads up to 450 kg can be carried with these types of trolleys by means of the heavy-type trolleys that have 4 rollers. As trolleys can only be connected to the middle links of the chains, their clearances can be determined as 8" and its powers.
  
6" (TR678) Conveyor Systems: These systems are so called because the chain pitches are very close to 6". The trolleys mounted on the chain can move on NPI 160 - 180 profiles. The unit load carrying capacities of the standard trolleys is 400 kg, and the breaking off force of the chain is 38500 kg. As trolleys can only be connected to the middle links of the chains, their clearances can be determined as 12" and its powers
