QUIET PORTABILITY with Quick Cable Disconnect

The 477 Series features a compact, vertical design when robust power is needed in tight spaces. Lift/pull up to 2,000 pounds in any direction or orientation: floor, ceiling, or wall. Machine-cut helical and worm gears offer quiet and precise power transfers and continuous lubrication ensures long life. Ideal for wastewater, construction, and manufacturing applications.

Portable Design

  • Optional integrated pressure plate prevents unspooling during transport
  • Mounts on wall, ceiling, or floor for maximum flexibility
  • Lightweight cast aluminum drum and gearbox

Premium Motor & Configurations

  • Brushless-design, totally enclosed AC induction motor provides superior life
  • Quiet operation in both directions
  • 115-volt single phase standard, with other voltages available (single-and three-phase configurations)

Durable Winch Frame & Component Construction

  • Cast aluminum drum, frame, and gearbox (with enamel or optional epoxy coating) resist corrosion for extreme conditions and applications

Internal Mechanical Load Brake

  • Internal mechanical brake helps control loads and facilitates controlled operation
  • Wet-brake design increases durability by dissipating heat and reducing wear
