WHAT IS STACKER-RECLAIMER WHEEL?

The stacker-reclaimer wheel is a key load-bearing component of bulk cargo handling equipment in ports. It is usually made of 35CrMnSi steel forgings and must meet the technical requirements of the JB/T 4149-2010 standard for a 15mm hardened layer depth. The stacker-reclaimer wheel is the core component of its traveling mechanism, responsible for supporting the weight of the entire machine and enabling the equipment to move on the track.

MANUFACTURING PROCESS OF THE HEAVY DUTY WHEEL FOR STACKER RECLAIMER

The materials of the stacker-reclaimer wheel usually include carbon steel, alloy steel and stainless steel. The manufacturing process is diverse, including free forging, die forging, ring forging and rolling ring, etc., and the deformation temperature is hot forging. The wheel forgings need to be tempered and quenched to ensure their quality and durability.

Applications of stacker relaimer wheels

Single-side wheel sets are mainly used in running mechanisms of gantry cranes below 5 tons, and trolley mechanisms of double-girder gantry cranes.

Double-side wheel sets are mainly used in gantry cranes, bridge crane main carriages, casting crane trolleys, electric flat cars, transfer trolleys, ship unloaders, shipyards, port machinery, coal unloaders, stacker reclaimers, quay cranes, etc.

THE SERVICE LIFE OF HEAVY DUTY WHEELS FOR STACKER RECLAIMER

The service life of heavy duty wheels for stacker reclaimer is affected by many factors and usually fluctuates between 3 and 10 years. The specific service life needs to be comprehensively evaluated based on working conditions, maintenance level and design parameters. The following are key influencing factors and measures to extend the life:

Factors	Influence description	Typical life range
Wheel pressure load	Overload or uneven wheel pressure distribution will accelerate fatigue wear (such as single wheel load exceeds the standard)	High load can be shortened to 2~3 years
Track condition	Unstraight track, joint misalignment or settlement will lead to rail gnawing and eccentric wear	Poor track reduces life by 30%~50%
Material and hardness	High-quality alloy steel (such as ZG50SiMn) + surface quenching (HRC≥45) has a life of more than 50% longer than ordinary materials	High-end materials can reach 8~10 years
Operation frequency	Continuous operation (such as 24-hour operation in ports) wears faster than intermittent operation	High-frequency use is shortened to 3~5 years
Environmental conditions	Dust, moisture or corrosive gases (such as coastal salt spray) accelerate rust and surface peeling	Harsh environment reduces life by 20%~40%

Scrap Standard of the heavy duty wheel

Wheel rim wear: Remaining height <15mm (new wheel rim is usually 25~30mm).
Tread wear: Thickness reduction of 10% or grooves or peeling with a depth of >5mm.
Crack defects: Visible cracks appear on the wheel hub, spokes or tread (need to be confirmed by magnetic particle inspection).
Deformation: Wheel radial runout >1mm or axial runout >2mm.

Maintenance of the heavy duty wheel for stacker reclaimer

Daily inspection and maintenance ‌

‌Track and foreign body cleaning ‌

Check the track for deformation and wear every day, and remove foreign objects such as stones and metal debris on the track in time to prevent the wheel from being blocked or abnormally worn.
Check whether the track connection bolts are loose to avoid shaking during equipment operation.

‌Wheel status inspection ‌

‌Wear inspection ‌: Observe whether the wheel rolling surface has uneven wear, peeling or cracks. Replace it if it is severely worn.
‌Hub lubrication ‌: Check the lubrication of the hub-type walking mechanism to ensure sufficient grease (mainly lithium-based grease).
‌Tire pressure ‌: The tire-type walking mechanism needs to check the air pressure regularly to avoid deformation or additional wear caused by insufficient air pressure.

‌Drive component inspection ‌

Check whether the connection bolts of the walking motor and reducer are loose, and whether there are abnormal sounds, abnormal heat or vibration during operation.

Wear and fault handling ‌

‌Wear replacement standard ‌

When the wheel rolling surface has deep peeling, cracks or wear that affects the walking stability, it needs to be replaced immediately.
If the surface of the polyurethane drive wheel is cracked or aged (especially in low temperature or chemical corrosion environment), it should be replaced with a more weather-resistant wheel body in time.

‌Bearing maintenance‌

Bearing failure is a common problem. The lubrication status needs to be checked regularly. When replacing damaged bearings, sealed design models are preferred to prevent dust/water intrusion.
When the bearing makes abnormal noise or overheats, stop the machine for inspection immediately to avoid collateral damage.

‌Overload and operating specifications‌

Strictly operate according to the rated load to avoid sudden start and stop causing wheel impact damage.
When the load is unbalanced, adjust the counterweight to reduce the pressure on one side of the wheel.
