Setting the standards in level wind technology:
a totally self-compensating level wind for precise and continuous spooling of wire rope or cable.
Never needs adjustment.

Available as optional equipment for IR manufactured winches or as
a retrofit for winches and cable reels of other manufacturers. No attachment to existing winch is required. Retrofit unit is a free- standing design, which can fit any winch or cable reel, etc.
How It Works:
The IR Accu-Spool level wind is universally adaptable to the entire Force 5 air winch line and to winches produced by other manufacturers. When winch fleet angles exceed 2 degrees, wire rope spooling becomes difficult. The IR Accu-Spool level wind will spool the rope uniformly and repeatedly on the drum in applications where fleet angles vary from 0 to 26 degrees.
Standard features:
•Rack and pinion drive resists wear from corrosive elements when compared with diamond screw type level winds
•No gear interlocks or drive chains to wear, corrode or get out of adjustment
•Durable radial piston air motor provides independent power source
•No drive attachment to the winch is required
•Bronze worm drive and steel worm gear
•Steel guide bar and guide rollers
•Heavy duty rack and pinion drive allows for precise, continuous spooling and reduced wire rope wear
•Totally self-compensating and adjusting. The design over- comes the timing problems inherent in diamond screw types of level winds
•Compensates for fleet angles up to 26˚
•Allows wire rope take off in almost any direction
•Emergency manual override on control systems is standard
•Line tension of approximately 5% of actual load is required to activate the Accu-Spool
The main components are:
1. Guide bar: alloy steel tube with rack and pinion drive
2. Guide system: steel guide rollers, worm gear drive and radial piston air motor

The Accu-Spool’s sensor rollers keep the level wind axis and drum perpendicular to the wire rope on the drum. When the winch line pull pressure is applied to the sensor roller, the roller will activate linkage
that opens the motor valve, driving the level wind in the appropriate direction to spool the wire rope evenly on the drum.
