Industry Overview

The construction‑machinery industry is advancing rapidly toward intelligence and green development, imposing higher requirements on transmission systems for efficiency, reliability and compact layout. Boneng Transmission supplies integrated transmission solutions featuring high torque density and strong vibration‑resistance for main equipment including tower cranes, mixing plants and bridge erecting machines, with self‑developed gear reducers, motors and drives. We help customers achieve precise control and energy‑efficiency improvement under heavy‑load operating conditions.

Product Empowerment

Focused on transmission‑system innovation, Boneng Transmission delivers all‑in‑one solutions combining gearboxes, motors and variable‑frequency drives. Featuring precise control, high‑efficiency power transmission and dependable operation, our products drive construction‑machinery development toward greater intelligence, safety and high performance.

Variable Frequency DrivesA1 Variable Frequency DriveHigh-performance vector-type variable frequency, supporting closed-loop vector control and multiple communication protocols. In tower cranes' rotation, bridge erection machines' movement and other mechanisms, it can achieve zero-speed hovering, smooth start and stop, and multi-motor synchronization, significantly enhancing the overall safety and operational accuracy of the machine.View Details Gear Asynchronous MotorK Helical-Bevel GearmotorCompact structure, strong torsional resistance. Especially suitable for belt conveyors in mixing stations, spiral mixers for ingredient distribution, and feeding systems for mobile crushers. It can operate stably for a long time in dusty and vibrating environments, saving installation space and reducing maintenance frequency.View Details Planetary GearboxPW Planetary Winch GearboxHigh-precision planetary structure, which can be directly embedded in the reel. Specifically designed for tower crane lifting mechanisms and luffing mechanisms, it features a large speed ratio and high radial load-bearing capacity. It can output extremely large torque within a limited space, helping the main unit achieve lightweight and integrated design.View Details GearboxH Helical Gearbox &B Bevel-helical GearboxHigh-torque parallel-axis/orthogonal-axis industrial gearboxes, featuring high-strength alloy steel tooth surfaces and reinforced housings, have strong shock resistance. They are suitable for continuous heavy-load positions such as the mixing machine of asphalt mixing stations and the main hoist of bridge erection machines, and provide reliable load-bearing.View Details

Technical highlights

Roller integrated assembly

  • The PW built-in planetary gearbox is directly installed inside the lifting drum, eliminating the need for a coupling. This results in a weight reduction of over 15% for the entire machine, making it suitable for compact models such as hammerhead towers.

Zero-speed full-torque hovering

  • The A1 drive unit employs closed-loop vector control, combined with a brake system to provide dual anti-slip hooks. The positioning accuracy of the micro-motion mechanism reaches the level of millimeters.

Smooth rotation with strong resistance to wind sway

  • The PS rotary planetary gearbox, in conjunction with the S-shaped acceleration and deceleration curve, eliminates the start-stop shock and effectively resists the swinging of the boom caused by lateral wind loads.

Full-condition thermal management

  • The integrated lubrication design, combined with forced air cooling, ensures that the tower crane can operate at a high frequency in a 50℃ hot environment without overheating.

Reference Cases

Localized Replacement for Tower‑Crane Hoisting Mechanism

Customer Pain Points

Imported planetary hoisting reducers were used long‑term, bringing high procurement costs and a 14‑week lead time that seriously delayed new‑model launches.

Boneng Solution & Benefits

  • Adopt embedded PW gearbox to replace imported units with customized mounting interfaces
  • Positioning accuracy matches imported benchmarks; costs cut by around 50 %; lead‑time shortened to 6 weeks for fast delivery

Improved Drive Reliability for Asphalt‑Mixing Plant

Customer Pain Points

Original belt‑driven mixer drives suffered frequent slipping at high temperatures. Frequent seal failures on powder‑conveying screws caused oil leakage, jeopardizing environmental compliance and production continuity.

Boneng Solution & Benefits

  • Deploy HB heavy‑duty gearboxes for direct drive of mixing drums, plus upgraded K‑series motors for screw feeding
  • Multi‑stage sealing completely eliminates high‑temperature oil leakage; annual maintenance costs reduced by 40 %

Weight Reduction & Efficiency Boost for Hundred‑to‑Thousand‑Ton Bridge Erecting Machine

Customer Pain Points

Legacy hoisting mechanisms were bulky and heavy, severely limiting lightweight design and creating great difficulties for erection, disassembly and span‑crossing relocation.

Boneng Solution & Benefits

  • After adopting Boneng planetary transmission systems, hoisting‑mechanism volume reduced by over 30 % and total weight cut by more than 25 %
  • The overall machine becomes more compact, greatly easing transportation and counterweight challenges during span‑crossing operations.

Custom‑Built for Severe Operating Conditions of Mobile Crusher

Customer Pain Points

Mobile crushers operate continuously under complex conditions of heavy shock, low‑speed heavy load, dust and vibration. Conventional transmission systems suffer insufficient load capacity, unstable performance and frequent maintenance.

Boneng Solution & Benefits

  • Custom mechatronic transmission solution: H/P heavy‑duty gearbox + K‑series geared motor + A1 variable‑frequency drive
  • Fully covers core processes including feeding, crushing and discharge conveying
