No head or tail undercarriage provides greater clearance under the conveyor.
USED IN THESE INDUSTRIES: AGGREGATE, PORTS & TERMINALS
Belt Scrapers (Twin-Edge) & Tensioning System: Patented
Situated at the discharge end on both conveyors, Thor’s exclusive twin-edge belt scrapers are designed for a cleaner return and longer belt life. All scrapers are manufactured using a tough ¾” thick, 10” wide urethane blade combined with an extension spring. The blade is reversible for double lifespan. The PATENTED belt scraper tensioning system provides maximum control and better usage of the blade.
Belt Splice: Vulcanized
All belt splices are vulcanized in house to ensure greater belt life for all of our end users. Vulcanizing also prolongs the life of the belt scraper. Thor Global uses premium quality and high tensile strength belting.
Thor Global is very aware that bulk material handling environments can be extremely harsh on electrical components. This is why the conveyor uses over sized IEC contactors for all applications to provide a more robust system
Electrical Cable Harness Pulley: UHMW
Custom made UHMW pulleys, which are attached to the electrical cable harness that supplies the inner truss, are guaranteed not to seize up.
Emergency Braking System
In the unlikely event of winch cable breakage, the braking system is immediately engaged, preventing the inner truss assembly from traveling backwards. The emergency braking system will prevent excessive damage from occurring and more importantly eliminates the risk of injury to any individual.
Gear Reducers: CLASS 2
Dodge, always CLASS 2 with no need to upgrade from CLASS 1.
Idlers: CEMA C
Strongco CEMA C idlers are standard on all machines. They are intended to last twice as long as CEMA B. Thor uses nothing less than the best!
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
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.
PLC: MICROLOGIX 1400
The automation control system uses the legendary bulletproof Allen-Bradley SLC 503 Series PLC (Programmable Logic Controller). The system is powerful, reliable and flexible.
Program: Windrow Auto Mode
Thor Global’s basic programming was originally designed to minimize segregation by stockpiling material in concentric rows called windrows. The operator has the ability to set specific parameters based on a radial degree limit and extension retraction limit.
Push Button Control
As a preventative measure, Thor Global has applied basic push button technology in addition to the standard touch screen system to provide a failsafe back-up system for increased comfort and reliability.
Galvanized steel mesh guarding surrounding the main conveyor and safety guards at all pinch points provide ultimate protection for all operators and personnel within close range of the conveyor.
Side Guide Rollers: UHMW
Thor Global’s more forgiving UHMW guidance system does not employ metal on metal contact and covers the entire height of the inner chord prolonging the lifespan of the inner telescopic.
Steel: 60,000 psi
Thor Global uses 60,000 psi yield strength steel versus the industry norm of 45,000 psi yield strength for all HSS (Hollow Structural Section) tubing. This FINER grain steel provides additional strength without additional weight.
Stone Box Skirting (Floating): UHMW
Located between the stone box and the conveyor belt, the UHMW skirting is designed to “float” on the belt via slotted holes, maintaining a constant point of contact, thereby minimizing spillage and wear due to friction.
Tail Pulley Access
An opening located on the counter weight allows safe visual inspection and greasing of the tail pulley bearings during operation.
Tail Pulley Kicker Bar
A kicker bar is attached to the tail pillow block bearings of the inner and outer conveyors to keep material off the pulley, which prevents tracking and belt damage.
Touch Screen Control: HMI08CE
The touch-screen control provides a simple to use and fully automated program for setting parameters and pile configurations. All controls are on the same screen. Cutler-Hammer touch-screens are NEMA 4 rated and very durable, withstanding a shock load of 30Gs. These screens come with standard replaceable overlays, to ensure a clear view.
Touch Screen Sun Visor: Anti Glare
An enclosure around the centric control system removes glare for increased touch-screen visibility.
A factory trained, Thor authorized representative will be on site to ensure that you and your operators know all there is to know about how the conveyor operates.
Ultrasonic sensors utilize the PLC to automatically maintain a pre-determined drop distance from the head pulley to the stockpile as well as stopping all radial movement when no material is detected on the conveyor belt. These sensors never come in contact with the material and are maintenance free.
Variable Frequency Drive
Variable frequency drive provides smooth acceleration and deceleration of the, eliminating jerky or jarring starts and stops. The VFD (Variable Frequency Drive) also allows the operator to adjust the radial travel speed.
A standard box shaped design has tapered sides with a wider feed opening. Other custom designs are available upon request.
Contactors & Starters: NEMA
NEMA rated starters and contactors are available upon request.
Realizing that some customers have to work in harsh environments with corrosive materials, Thor is the first and only manufacturer to provide a unit that can withstand your tough environment. Machines are fully Hot-Dip galvanized before assembly. Hot-Dip Galvanizing relieves the internal stresses of welded components, providing a fully stress relieved structure. Zinc has a very high relative corrosion resistance.
We understand the importance of corporate image, so we at Thor Global will always try to meet the specific requests of our customers as best as we can.
An optional second radial drive allows the conveyor to maintain traction in the most demanding conditions.
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.
Wire Remote Touch Screen: Dual
Dual wire remote control involves keeping the touch screen panel on the conveyor and adding a second panel up to 1000ft away from the conveyor. A selector switch is applied to control which control station is active. Dual wire remote control provides increased versatility.
Wireless Remote Control
This system allows wireless remote control operation of the conveyor for movements such as telescoping in and out, or luffing and slewing. Wireless remote control provides increased visibility and flexibility. Wireless remote control is ideal for ship loading applications where visibility from the main control panel is limited.
Belt Alignment Sensor
A belt alignment sensor may be applied in connection with the PLC to monitor the belt alignment and alert the operator when an adjustment is required to further extend belt longevity. Also known as belt tracking.
Belt Scrapers: H/D
HD (High Definition) belt scrapers are available upon request. Includes 2 primary and 1 secondary blade.
Belt Covers: Patented
Thor Global’s patented belt covers can be easily installed into any existing conveyor system. Ultra lightweight galvanized steel structural tubing and single bolt connections make these conveyor covers easy to handle, remove and assemble. Individual spring tensioning systems keep the covers secure and accessible for maintenance and repair. Lightweight UV resistant polyurethane material dramatically reduces wind load by 80%. Provides excellent dust control.
A telescoping spout has been designed for applications that require specialized dust control. This unit can be attached to select models. The spout is connected to the PLC for automated control with an extension of up to 16ft. The spout can be retracted to a minimum of 4ft. Telescopic spouts are ideal for ship loading applications.
Zero Speed Switches
Zero speed switches located on the inner and outer conveyor utilize PLC to detect if the belt is slipping and thereby prevent the stacker from overloading beyond its maximum capacity.
