Drive Wheel Bogie Assembly
Click for details
Drive Wheel Bogie Assembly
The drive wheel bogie assembly facilitates the linear movement of the stacker reclaimer along the stockyard rail tracks. It comprises a rugged bogie frame fitted with high-strength alloy steel drive and idler wheels. Power is transmitted through a motor–gearbox combination, ensuring torque is delivered effectively to the drive wheels. Anti-derailment rollers and flanged wheels provide stability, even under dynamic loading conditions. This assembly is engineered to bear substantial axial and radial loads due to the reclaimer’s structural weight and operational stresses.
Slew Bearing (Slewing Ring)

Slew Bearing (Slewing Ring)
The slew bearing enables 360° rotation of the superstructure (boom, bucket wheel, etc.) around the vertical axis. Typically a three-row or cross-roller bearing, it is designed to accommodate simultaneous axial, radial, and overturning moment loads. Integrated with internal or external gear teeth, it engages with the slewing drive system. Protected with heavy-duty seals and connected to a centralized lubrication system, the bearing remains operational in coal dust and moisture-prone environments, ensuring rotational smoothness and long service life.
Buckets

Buckets
These buckets are mounted on the periphery of the bucket wheel and are responsible for material excavation during reclaiming operations. Constructed from high-wear-resistant steel like Hardox 400/500, they endure continuous contact with abrasive coal. The curved geometry and cutting lips optimize digging efficiency and discharge accuracy. Buckets are either bolted (replaceable) or fabricated, and discharge coal via the wheel chute into the central conveyor, forming a vital link in material flow.
Bucket Wheel Body

Bucket Wheel Body
This rotating assembly houses the buckets and drives them through the stockpile. Made from precision-welded steel segments, it features either drum-type or spoke-hub construction based on the design. Powered by a dedicated drive package—typically an electric motor, planetary gearbox, and fluid coupling—the wheel body is dynamically balanced to minimize vibration, reduce bearing loads, and ensure smooth continuous operation.
Wagon Locking System

Wagon Locking System
Before the tippling cycle begins, the wagon must be secured in position. The locking system consists of hydraulically/pneumatically actuated plungers or pins, embedded in the base frame or track. These locks are interlocked with the PLC logic to prevent tipping unless full engagement is confirmed via proximity sensors. Designed to absorb the longitudinal forces from in-motion wagons and the torque from tipping, this system is essential for safe unloading.
Wagon Clamping Assembly

Wagon Clamping Assembly
To restrain lateral and vertical wagon movement during tippling, the clamping assembly uses hydraulic arms or pads to grip the wagon's side frames. It adjusts its force based on wagon type—accommodating both BOXN and BOBRN designs. Built from high-tensile steel with optional rubber buffers for wagon protection, it ensures secure holding throughout the 150°–180° tippler rotation, preventing derailment and ensuring complete unloading.
Upper Holding Beam

Upper Holding Beam
Primarily used in tandem tippler setups or side-arm charger systems, the upper holding beam stabilizes the wagon's upper portion. It is a robust fabricated structure equipped with hydraulic or mechanical locking arrangements. Synchronized with the tippler rotation, it prevents vertical lift or tilting, particularly during high-speed or asymmetric loading conditions. Contact surfaces may include rollers or pads to handle minor misalignments safely.
Hammers

Hammers
Installed in hammer mills or ring granulators, these elements deliver high-velocity impacts to coal lumps. Manufactured from alloy or manganese steel and heat-treated, they resist deformation and wear. Available in both fixed and swinging configurations, their design includes tapered profiles to enhance breakage efficiency and reduce specific energy consumption. Quick-change mechanisms allow for minimal downtime during maintenance.
Crusher Rotor Assembly
Click for details
Crusher Rotor Assembly
This is the rotating powerhouse of hammer or impact crushers. It consists of a forged steel shaft with mounted disc plates and hammer arms. Dynamically balanced and supported on anti-friction bearings, the rotor ensures consistent impact force and material throughput. Torque is transferred via keyways or splined shafts from the drive assembly, and its rotational speed dictates the size and shape of crushed material.
Cardan Shafts

Cardan Shafts
Used to transmit rotary motion between the drive motor and crusher rotor across misaligned axes, cardan shafts are engineered for high-torque applications. These universal shafts consist of telescopic tubes and precision universal joints at each end, allowing angular and axial flexibility. Made from alloy steel, they are statically and dynamically balanced, with grease-lubricated bearings ensuring smooth power delivery and long service intervals.
Cage Adjustment Assembly
Click for details
Cage Adjustment Assembly
Common in ring granulators, the cage adjustment assembly regulates the clearance between the rotor hammers and the surrounding breaker ring. This controls the output size of the crushed coal. Adjustments are made manually or hydraulically via jacks or actuators. Components are constructed from wear-resistant materials and may include visual indicators and locking devices to maintain uniform clearance and optimal crushing efficiency.
Apron Pans
Click for details
Apron Pans
Apron pans form the conveying surface of apron feeders, transporting bulk material like coal from hoppers to crushers. These overlapping steel trays are made from Hardox or manganese steel, designed to handle large particle sizes and heavy impact loads. Their interlocking design minimizes spillage, and their ribbed structure provides strength and stability under harsh conditions.
Chain Link Assembly
Click for details
Chain Link Assembly
The chain link assembly drives the apron pans and bears the bulk of the conveyed load. These crawler-type links include pin-and-bush arrangements for flexibility and are made from alloy steel for high tensile strength and wear resistance. Driven by sprockets and supported on rollers, the assembly ensures smooth material movement, with tensioning systems maintaining alignment over long periods of operation.
