Telescopic Cable Mast Conveyor

Used in these industries:
Aggregate, Ports & Terminals
Thor Global has applied telescopic technology to a traditional cable mast system that has been successful in stockpiling applications for decades. The Thor TowerStacker™ is a scalable product that has been engineered to perfection using a rail system configuration that is capable of handling the higher pressures of a larger machine.

Pile Higher

Enlarged structural design enables you to stockpile material in excess of 350,000 tons and 4000 STPH.

Easy Maintenance

Conveyor can be lowered all the way to the ground to provide easy access for maintenance.

Greater Clearance

No head or tail undercarriage provides greater clearance under the conveyor.

  • LES: Patented
    LES: Patented
    The patented LES (Load Equalizing System) was engineered to evenly distribute the constantly changing load of the inner truss as it extends and retracts. When extending and retracting a telescopic, the forces applied to the inner structure can be very high. The system uses a unique 4-roller design to effectively distribute this load over the entire inner structure. The LES is located under the inner conveyor to avoid material build up. The combination of the upper and lower LES keeps loads even on all 4 rollers for worry-free operation.
  • Limit Switches: NEMA 4
    Limit Switches: NEMA 4
    NEMA 4 rated back-up safety switches are located in various positions across the stacker. Weatherproof seals ensure that the switches operate reliably under harsh conditions, thereby eliminating potential downtime.

Zinc has a very high relative corrosion resistance.
  • Program Package: Zero Segregation & Max Pile Auto Mode
    Program Package: Zero Segregation & Max Pile Auto Mode
    Zero segregation programming is recommended when minimizing segregation is of the utmost importance. The primary function of zero segregation programming is a stepping function, which prevents material segregation along the outside of the pile in addition to the inside of the pile. The most unique function of Thor’s zero segregation program, is the ability to control the degree of step, which enables you to control the exact size of the pile. Max Pile programming is recommended when segregation is not of any importance. The conveyor minimizes all movements in this auto mode.
