REINTJES Gearbox

WAF/LAF 2346 – 7760

1,800 – 7,083 kW


High-power reverse-reduction gearboxes for the largest workboat applications — ocean tugs, ATBs, large dredgers, and major commercial vessels. Engineered with welded steel housings for the most demanding continuous-duty propulsion installations.

REINTJES WAF/LAF 2346-7760 Marine Gearbox
Key Advantages

Built for the Largest Workboat Applications

The WAF/LAF 2346 – 7760 range delivers the torque density needed for ocean-class tugs, ATBs, and major commercial vessels — backed by REINTJES' welded-steel housing construction and 80+ years of heavy-duty marine gearbox experience.

Welded Steel Housing

Welded steel housings deliver maximum strength and shock resistance for the most demanding ocean-class propulsion applications.

Continuous-Duty Reliability

Hydraulically operated disc clutches and oversized roller bearings ensure dependable continuous-duty performance for ocean operations.

Multiple Offset Configurations

Available in horizontal and vertical offset configurations to suit diverse engine room layouts on the largest workboats.

Low Operating Noise

Helical spur gears, case-hardened and tooth-flank ground with precision, deliver smooth, quiet operation across the full power range.
