WEISHI supplies roadheader parts for underground mining and tunneling equipment, including roadheader cutting arms, cutting gearboxes, and cutting picks. These components support the cutting and transmission systems of boom-type roadheaders operating in coal seams, mixed coal-rock formations, and hard rock conditions.
As a roadheader equipment manufacturer, WEISHI understands the importance of selecting replacement parts that match the machine model, cutting system configuration, and actual operating conditions. Our parts range is designed to support equipment maintenance, component replacement, and long-term underground excavation operations.
Whether you need replacement roadheader cutting bits, a cutting gearbox, or a complete cutting arm assembly, please provide your machine model, component specifications, and part identification details so our team can review the requirements and assist with parts selection.
Our current product range focuses on essential components of the roadheader cutting system.
The cutting arm is an important part of the roadheader cutting assembly, supporting the cutting head and transmitting cutting loads during excavation. Selecting a suitable cutting arm requires confirmation of the machine structure, mounting dimensions, cutting head configuration, and operating requirements.
Roadheader cutting gearboxes transmit power from the cutting motor to the cutting head. When selecting a replacement gearbox, buyers should check rated input power, transmission ratio, output torque, mounting dimensions, shaft connections, and lubrication requirements.
Roadheader cutting picks are consumable wear parts installed on the cutting head. They directly contact the rock or coal during excavation. Cutting pick selection should consider rock hardness, abrasiveness, pick geometry, carbide tip configuration, and holder compatibility.
WEISHI offers roadheader cutting picks including S135 (U135) and S47 (U47) types. Please confirm the required dimensions and specifications before ordering.
Correct component compatibility is essential when purchasing roadheader spare parts. Even when two roadheaders have similar cutting motor power or belong to the same equipment series, their cutting assemblies, gearbox connections, and cutting pick specifications may differ.
Before ordering replacement parts, identify the exact roadheader model and verify the original component specifications.

For EBZ series roadheaders, component selection should be based on the equipment's specific model and configuration.
Different models may use different cutting assemblies and transmission components, even within the same roadheader family. Machine model information alone may not always be sufficient to identify the correct replacement part.
When requesting parts for WEISHI roadheaders, please provide the complete equipment model, serial number where available, and the original part number or component drawing.
For components from other roadheader models or manufacturers, technical compatibility must be reviewed individually before ordering.
Roadheader cutting performance and maintenance costs depend heavily on the condition and suitability of the cutting system components.
When selecting parts, buyers should consider the following factors.
Rock compressive strength is an important reference for selecting cutting tools, but it is not the only factor.
Highly abrasive rocks containing quartz or other hard minerals can accelerate cutting pick wear. In such conditions, carbide tip quality, pick geometry, and replacement frequency become particularly important.
The cutting pick must match the holder installed on the cutting head.
Incorrect shank dimensions or incompatible fixing arrangements may lead to poor retention, abnormal wear, or damage to the holder.
Before purchasing roadheader cutting bits, confirm the pick model, shank diameter, overall length, carbide tip specification, and fixing method.
A replacement cutting gearbox must meet the mechanical requirements of the cutting system.
Key considerations include motor power, operating speed, reduction ratio, output torque, installation dimensions, and lubrication arrangements.
A gearbox should not be selected solely because its rated power appears similar to that of the original component.
Dust, moisture, vibration, impact loads, and continuous operation can affect component performance and maintenance needs.
For demanding underground conditions, the selection process should also consider sealing arrangements, lubrication, inspection accessibility, and replacement procedures.
Regular inspection of roadheader cutting components helps identify wear before it develops into more serious equipment damage.
The following table summarizes common inspection points and possible maintenance actions.
| Component | Common Inspection Points | Recommended Action |
|---|---|---|
| Cutting Picks | Worn carbide tips, broken tips, uneven wear, restricted rotation | Replace damaged or excessively worn picks and inspect holders |
| Cutting Pick Holders | Loose fit, excessive bore wear, cracks, deformation | Inspect mounting condition and replace damaged holders |
| Cutting Gearbox | Abnormal noise, vibration, lubricant leakage, overheating | Stop and inspect according to the manufacturer's maintenance procedure |
| Cutting Arm | Structural cracks, loose fasteners, abnormal movement, connection wear | Inspect structural and connection components |
| Sealing Components | Oil leakage, damaged seals, contamination | Check sealing condition and replace defective components |
Maintenance intervals should follow the equipment manufacturer's instructions and actual site conditions.
Providing complete part identification information helps reduce the risk of incorrect replacement components and unnecessary equipment downtime.
