Double-Ended Winches Provide Greater Versatility

From the standard LANTEC specification sheets, you can get a good idea of the range of performance offered by the different LANTEC winch models. But sometimes you find that the performance required doesn't appear to be available from any of the standard models.
First of all, don't give up! Sometimes the solution is just a matter of changing to a different type of motor. Other times, maybe we can come up with a custom drum size to meet the requirement.

Finally, if the requirement for line pull or line speed seems to go well beyond any LANTEC winch available, the solution may be a double-ended winch. With this option, the winch can deliver twice the torque as the standard model. The available torque can be used to generate twice the line pull for a given drum size, compared to the equivalent standard model. Or it can be used with a different gear ratio or larger diameter drum to produce twice the line speed at a given line pull.

The standard winch has the motor, brake and first gear reduction on one side of the drum, and the remaining gear reductions attached at the other end. In a double-ended winch, you effectively have one set of motor, brake and all gear reductions on each end of a single drum on a single frame.

Of course, to power a double-ended winch, you need twice the power of the equivalent standard winch. For hydraulic power, the typical solution is to distribute the hydraulic flow from a common source to each motor. For electric power, you simply provide the voltage and current demanded by the motors.

Take a look at the Performance Comparison. The computed performance of the Model 750-131 SE (single-ended) closely matches the data in the Model 750 Specification Sheet. The Model 750-131 DE (double-ended) uses the same drum, but with larger diameter wire rope to accommodate the higher line pull, nearly double the standard model. The second DE winch, a Model 752-131 DE, uses a faster gear ratio to generate nearly twice the line speed as the standard model.

Performance Comparison

The advantage of the double-ended winch is that it extends your range of solutions that much farther. Most other winches lack the ability to be reconfigured in this way. The few other winches operating in this performance range are often custom solutions that are very expensive. LANTEC’s marvelous configurability gives you the strength of a custom solution at an off-the-shelf price.
