Construction Machinery

Gearboxes are the "power multipliers" of construction machinery. They convert high-speed motor/engine rotation into low-speed, high-torque output to drive various equipment on site.

Major Application Scenarios

- Hoisting and vertical transport:

  - Tower cranes: used in hoisting, slewing, and luffing mechanisms for smooth lifting and precise boom movement.

  - Construction hoists: provide stable power for moving personnel and materials.

  - Truck-mounted and mobile cranes: applied in slewing and hoisting functions.

- Earthmoving and foundation work:

  - Excavators: drive slewing and travel mechanisms under heavy shock loads.

  - Bulldozers: supply thrust for track travel systems.

  - Road rollers: drive travel systems to maintain uniform compaction speed.

  - Drilling rigs and tunnel boring machines (TBMs): used in drilling and rotating systems for tunnels and pile foundations.

- Material handling and processing:

  - Concrete mixers and mixer trucks: drive mixing drums at low speed for uniform concrete.

  - Concrete pump trucks: used in pumping systems to provide high-pressure delivery.

  - Rebar processing machinery: e.g., straightening and bending machines.

- Other auxiliary equipment:

  - Aerial work platforms: drive boom slewing and luffing.

  - Mechanical parking systems: used for vehicle lifting and transfer devices.
