Construction Gearbox Solutions | Heavy Duty Drives | TANHON
Construction material production runs around the clock. Mixing, pressing, extrusion, and forming equipment all depend on drives that hold up against dust, vibration, and heavy cyclic loads.
Standard gearboxes wear out fast on construction production lines. Dust contaminates seals, shock loads damage gear teeth, and inconsistent torque ruins product quality.
At TANHON, we engineer gearboxes specifically for construction material manufacturing. We focus on sealed protection, high torque density, and continuous-duty reliability.
Engineering Built for Construction Production Lines
Construction material plants demand drives that keep running through dust, heat, and constant cyclic loading. Here is how we build for that environment.
1. Sealed, Dust-Resistant Housings
Clay dust, cement powder, and mineral fines work like sandpaper on bearings and seals. Our multi-stage sealing systems keep contaminants out of the oil chamber and protect internal components for the long run.
2. Heavy-Duty Cast Iron Construction
Pressing, extrusion, and mixing generate constant vibration and shock loading. Our cast iron housings and case-hardened helical gears absorb these forces without cracking or premature wear.
3. High-Efficiency Helical Gear Trains
Precision-ground helical gears deliver over 95% efficiency, smooth torque transfer, and quiet operation. Lower energy loss means lower operating costs across long S1 continuous-duty cycles.
Gearboxes for Core Construction Applications
We provide drive solutions matched to the specific demands of construction material production equipment.
AAC Production Line Gearbox
The FM157-AD7 parallel shaft helical gearmotor features an extended bearing hub for higher overhung loads and a belt-driven input that absorbs shock from mixers, conveyors, and cutting equipment. A 96.53:1 ratio delivers the high torque needed for mixing drums and tilting tables.

Brick Making Machine Gearbox
The FA97 gearmotor pairs a 15 kW electromagnetic brake motor with a 20.07:1 ratio for precise, high-torque output. A Φ70mm hollow shaft and cast iron housing deliver the pressing force and instant stopping power that consistent brick dimensions require.

Dry Mortar Mixing Plant Gearbox
The THB4L700 twin-shaft gearbox delivers a 33:1 ratio across a 700mm shaft center distance, with paired 22 kW outputs that keep both mixer shafts synchronized. Sealed housing architecture and thermal-stable lubrication maintain consistent mixing across long production runs.

Crane Wheel Travel Gearbox
The MTH3HH9 three-stage parallel shaft helical gearbox delivers an 80:1 ratio for bridge crane, gantry crane, and overhead travelling crane wheel travel mechanisms. A hollow output shaft mounts directly over the wheel axle, while the IEC 200 B5 motor flange keeps the assembly compact within the end carriage structure.

Vertical Agitator Gearbox
The MJF79 arc-tooth hard-face bevel helical gearbox is factory-configured for M5 top-of-tank vertical agitator mounting. A 34.84:1 ratio delivers approximately 880 N.m at 41.4 RPM through a Φ300mm B5 output flange, with lubrication and sealing set for downward output shaft orientation in mixing and aeration tanks.

Don't see an exact fit for your construction equipment? We engineer custom industrial gearboxes tailored to your torque, dimensional, and environmental requirements.
Strict Factory Quality Control
A gearbox failure on a production line stops the whole plant. We test every single unit before it leaves our facility. Our quality assurance protocol includes:
No-Load & Load Testing
Every gearbox runs on our test bench to monitor temperature rise, gear mesh patterns, and verify power transmission efficiency before shipping.
Vibration & Noise Analysis
We use advanced sensors to measure operating frequencies. Low noise and low vibration confirm correct gear alignment and bearing seating.
Pressure Leak Testing
Dusty production environments demand perfect seals. We pressure test our housings to ensure zero oil leaks and complete protection against dust and moisture.
