EP-PWD3300 Planetary Winch Drive Gearbox – 33,000 Nm<\/h1>\n

Brevini PWD3300 Compatible Replacement | EVER POWER<\/strong><\/p>\n

The EP-PWD3300<\/strong> represents EVER POWER’s solution for high-cycle, high-torque winching where continuous duty is the norm. Engineered as a functional equivalent to the Brevini riduttori PWD3300, this unit is built for machine builders and operators who need 33,000 Nm<\/strong> output torque with predictable, maintenance-friendly performance.<\/p>\n

\"EP-PWD3300<\/p>\n

Product Overview<\/h2>\n

Key applications: heavy deck cranes on cargo vessels, land-based drilling rig drawworks, offshore derrick assist winches, heavy-duty forestry cableway systems<\/strong>. The EP-PWD3300 features a reinforced output-stage planet carrier with a 4-planet configuration<\/strong> to maximise load-sharing efficiency and extend bearing life in continuous-duty cycles.<\/p>\n

Working Principle<\/h2>\n

The 4-planet output stage<\/strong> is the defining feature of the EP-PWD3300. Conventional 3-planet designs distribute load across three contact points. Adding a fourth planet increases simultaneous tooth contacts, reducing tooth root stress by approximately 25% at the same torque level – resulting in longer fatigue life or greater tolerance of peak overload transients. Helical-cut teeth across all stages further reduce noise and smooth the torque curve for precision crane operations.<\/p>\n

Core Advantages<\/h2>\n\n\n\n\n\n\n
► 4-Planet Output Stage<\/strong>
25% lower tooth stress – extended life in continuous high-cycle duty.<\/td>\n		► Full Helical Tooth Profile<\/strong>
Quieter operation and gradual load engagement across all three stages.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
► High Overload Tolerance<\/strong>
Handles 2.8x rated torque peaks without plastic deformation of gear teeth.<\/td>\n		► Long Service Interval<\/strong>
Oil change intervals up to 2,500 hours with recommended synthetic lubricant.<\/td>\n<\/tr>\n
<\/td>\n<\/tr>\n
► Direct Drop-In for Brevini PWD3300<\/strong>
Identical bolt pattern, shaft dimensions and brake release port locations minimise retrofit downtime.<\/td>\n<\/tr>\n<\/table>\n

Structure and Material Technology<\/h2>\n

\"EVER<\/p>\n

All internal gear components are manufactured from 20CrMnTi and 17CrNiMo6 case-hardening steels<\/strong>. Carburising depth is controlled to 0.9-1.3 mm. After heat treatment, all gears undergo profile grinding to ISO accuracy grade 5. The output carrier is a single-piece forged construction. Radial shaft seals on the output side are double-lip FKM units<\/strong> rated for continuous immersion in synthetic oils.<\/p>\n

Selection Guide<\/h2>\n
    \n
  1. Confirm Duty Cycle Class<\/strong> (S1 continuous or S3\/S6 intermittent) to determine thermal de-rating.<\/li>\n
  2. State Peak Torque<\/strong> including shock factor. EP-PWD3300 handles up to 2.8x rated torque.<\/li>\n
  3. Motor Interface<\/strong> – SAE flange type, pilot diameter, shaft keyway dimensions.<\/li>\n
  4. Brake Release Pressure<\/strong> – typically 25-50 bar hydraulic; confirm available circuit pressure.<\/li>\n
  5. Drum Bore and Spline<\/strong> – provide drum drawing for our team to confirm fit.<\/li>\n<\/ol>\n
