Some types of cables, such as sea cables, require so much power and torque not any shredder is able to process them. On the other hand, long, stringy, flexible cables and plastics tend to wrap around the rotor of many shredders and create a block in the hopper. In some case the diameter and hardness of the cable require not just torque but also an aggressive rotor knife for an optimal and cost-efficient shredding.
When stringy, and soft cables jam a shredder it means in most cases downtime, which in many cases means emptying the hopper completely which is very time-consuming. One of the advantages of TANA shredders is the ease of removing non crushable items or clearing a jam through the opening side wall in the few cases a jam happens.
