Belt Systems

Belt System Components

Bucyrus belt conveyor solutions are quality engineered to meet each customer's mining or tunneling requirements and experienced Bucyrus engineers are always on-hand to supervise the installation to ensure a smooth start-up.

Power transmission configurations

• Alignment free
• Parallel shaft
• Right angle
• Concentric ("tucked under" polychain)

Drive technologies

• AC Variable frequency drives (VFD)
• DC Drives
• TPKL fluid transmission
• Dodge CST
• Reduced voltage/ solid state
• Fluid couplings

Belt Starters

Bucyrus offers belt starters for various drive technologies.

• Across the line starter for use with fluid couplings
• Reduced voltage starter for solid state drives
• DC motor controller
• AC Variable frequency motor controller

Alignment Free Drive

Benefits of an alignment free power transmission include:

• Ease of set-up and installation
• Ease of transportation into and around the mine
• Narrower overall drive width
• Universal mounting - same drive can be left hand or right hand mounted
• Reduced operating maintenance

Remote Discharge

Bucyrus remote discharge units are available in floor mounted or roof-hung configurations, as rigid A-Frame or adjustable boom with ratchet jacks. Discharges are designed for in-line or 90 degree transfer points.

Take-Up Sections

The take-up is a very critical portion of any belt system. Bucyrus take-ups apply accurate and very responsive belt tension to the system. Various take-up designs exist and each model is selected based on the application at hand. Some of the customer specified options include: one or two cylinders, active travel length (belt storage), hydraulic or electric winch, wire rope ratio. Each Bucyrus take-up pulley is designed for the maximum force each cylinder or winch can provide, this philosophy eliminates any weak links in the entire "take-up system". Bucyrus designs and promotes mainly hydraulic cylinder style take-up sections. All models are constructed for rugged, mine-duty applications and are engineered to operate with the other components of a belt conveyor system.

Hydraulic Power Units

Bucyrus hydraulic power packs are available for a variety of take-up sizes, such as 10, 25, 40, 60 or 100 hp. Each Bucyrus power pack comes with an on board PLC for controlling power pack operation; it can also interface with other mine wide communications. Since Bucyrus engineers are heavily involved with the belt system specifications, the power pack is delivered to the customer preprogrammed with the "proper setting" to handle the belt take-up application. With this "smart system" it is easy to re-configure the power pack for future applications or changes that may occur during the mining cycle.

Belt Storage Units

Excellent automatic belt "pay out" while advancing and belt storage when retreating are key advantages of specifying BUCYRUS belt storage units for a modern conveyor system. Their use eliminates belt splicing and belt removal on production shifts. Stored belt capacities range from 300 feet / 90 meters up to 2,000 feet / 610 meters. Belt tensioning applied by a storage unit facilitates the transmission of drive pulley torque and is needed to prevent excessive belt sag between carrying idlers. BUCYRUS offers three belt storage designs: electric and hydraulic constant tension winch or hydraulic cylinders.

Intermediate and Tail Loading Sections

Field proven Bucyrus belt conveyor transfer stations are designed and built for the steady, efficient transfer of extracted materials. Two common transfer requests are: in-line and right angle. Bucyrus' intermediate and tail loading sections are fabricated with either impact-resistant idlers or EXALON (polyethylene) impact slider beds and a structurally rigid, heavy-duty loading frame. Models are available for receiving discharges from an extensive range of haulage equipment - Un-A-Haulers® (coal haulers), Un-A-Trac® (scoops), feeder conveyors and shuttle cars.
