Heavy-Duty Large Cable Prefeeder and Pay-Off Stand for 1.5 t Spools WM-9151

›

The WM-9151 is a heavy-duty cable prefeeder for large spools: it carries up to 1.5 t on spools of Φ600–1,250 mm outer diameter and 550–950 mm width, and pays off cable from Φ3 to Φ45 mm at up to 100 m/min. A shaftless powered pay-off driven by a 5.5 kW motor and a frequency inverter starts, tracks and stops the feed automatically, while a mechanical swing bar with a movable counterweight sets the pay-off tension. Power supply is three-phase four-wire AC 380 V, 50/60 Hz.

Specifications

Key features

• Rated for 1.5 t spools — thirty times the 50 kg reel load of our next-largest pay-off, and the size large power and EV charging cable actually ships on
• Shaftless clamping — as pictured, the spool is gripped between two opposed cones drawn together by a handwheel, so there is no shaft to thread through the hub and no sleeve set to keep in stock
• Swing bar tension control — sliding the counterweight along the arm changes pay-off tension mechanically, with no electronics to tune
• Frequency inverter drive follows the downstream machine's demand, starting the spool as the bar drops and shutting down when the line stops
• As pictured, a drive-in loading cradle with rollers so a full spool can be rolled into position instead of lifted onto a shaft

What it processes

• New energy vehicle (EV) cable and charging pile cable feeding
• Power cable and BV building wire pay-off ahead of cutting, stripping or coiling lines
• Photovoltaic (solar) cable prefeeding
• Any line where cable arrives on Φ600–1,250 mm mill spools too heavy to be pulled by the downstream machine

Suited for: heavy cable that arrives on mill spools — EV and charging pile cable, power cable, photovoltaic cable and BV wire, Φ3 to 45 mm, on spools up to Φ1,250 mm and 1.5 t. Not suited for: light reels run at high line speed — the WM-9150 variable-speed wire pay-off carries 50 kg reels at up to 4 m/s (240 m/min), well above this machine’s 100 m/min. For vertical coils rather than flanged spools, the WM-9309 prefeeder with coil turntable takes 550 mm coils up to 50 kg and cable under Φ15 mm; for corrugated tube and hose, the WM-9120T cable and tube prefeeder; and for Ø0.6–5 mm coaxial cable that must not see tension, the WM-9105C tension-free coax prefeeder.

The problem this machine solves is inertia, not speed. A cutting or coiling machine downstream can pull a 20 kg reel around by itself; it cannot turn a 1.5 t spool, and if it tries, the cable stretches, the length count drifts and the feed jams at every restart. Here the spool is driven, and the swing bar decides when. The bar rests on the loop of slack cable: as the downstream machine consumes cable the bar rises, the drive spins the spool until the loop is restored, then it stops. The counterweight on the bar sets how hard it presses, which is the tension the cable actually sees.

Two things need to be checked before this machine is quoted. First the spool: hub bore, flange diameter, width and true loaded weight, because the Φ600–1,250 mm and 1.5 t figures are limits, not a guarantee that a given spool clamps and balances correctly between the cones. Second the supply: three-phase 380 V and a 5.5 kW motor is not a socket-and-plug installation, and the loading cradle needs floor space in front of the machine so a full spool can be rolled in.

Tell us the cable construction, the spool drawing and the line speed the downstream machine runs at, and we will confirm whether this size of prefeeder is the right one or whether a lighter unit from the same family covers the job.
