Hansen P4 Heavy Industrial Gearboxes & Reducers
The Hansen P4 Heavy Industrial Gearbox Series (featured model: P4-PND3-R42 Parallel 3-Stage Helical) represents Hansen Industrial Transmissions' flagship multi-megawatt drive platform, engineered for severe continuous-duty industrial operations in mining, water aeration, paper pulping, cement manufacturing, and heavy material handling conveyors. Built with a rigid single-piece **carcass housing design** that provides optimal load distribution and low sound emission levels, Hansen P4 gearboxes incorporate precision-carburized helical and bevel-helical gear tooth geometry. Featuring the patented **Carpex oil-tight sealing system** to prevent environmental contamination and oil leakage, these units offer superior thermal ratings supported by axial cooling fans, internal oil lubrication circuits, and water-cooling options. Available in **Parallel Shaft (2, 3, and 4-stage helical)** and **Right-Angle Shaft (2, 3, and 4-stage bevel-helical)** configurations across 19 modular frame sizes (P4 Size 19 to Size 26), covering torque ratings up to **800,000 Nm** and gear ratios from 1.25:1 to 630:1. WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio calculations, and 100% compliant mechanical replacement support for legacy **Hansen Power5 and Hansen HPP** industrial gearboxes.

Expert Technical Sourcing & Industrial System Integration Notes
When replacing older Hansen Power5 or HPP gearboxes operating on critical process lines, switching to current Hansen P4 series units delivers immediate performance benefits: 100% oil-tight sealing via Carpex sleeve technology, low noise carcass housing rigidity, increased thermal dissipation capacity, lower vibration levels, and complete physical mounting interchangeability with existing foundations. Simply provide us with your existing gearbox nameplate serial number or complete model code (e.g., P4-PND3-R42 or P5-RND3-R32), and our technical engineering team will deliver a 100% compliant replacement specification and proposal.
