Description
Utility substations and industrial service entrances require relentless pulling force on thick copper feeder cables. The Greenlee Puller Assembly delivers 10000 lb maximum pulling force through a two-speed planetary gear drive. Electrical input draws 15 Amps at 120 Volts. Shifting gears under load will shear internal shift dogs, requiring complete line tension release before changing pull speeds.
The primary drive train features a heavy-duty two-speed planetary gearbox machined from heat-treated alloy steel, encased in a ductile iron nose casting. A high-torque 120V AC electric motor couples direct to the planetary sun gear. The dual-diameter tapered capstan uses heat-treated cast steel with machined grip serrations that prevent pulling rope slip. The structural steel frame mounts heavy-duty locking pins that secure to boom extension tubes.
Two Speed Cable Puller Hardware
Two-speed planetary gearing shifts between high-speed slack rope uptake and low-speed maximum pulling force. The tapered capstan spool prevents overlapping rope wraps during high-tension cable installations.
- 10000 lb maximum pulling capacity conquers long industrial cable runs with multiple 90-degree bends.
- Two-speed gearbox delivers 10 feet per minute at full load and 20 feet per minute at low load.
- 120-volt 15-amp industrial motor plugs direct into standard commercial jobsite power outlets.
- Dual-diameter tapered capstan keeps pulling rope centered and eliminates dangerous rope overlap.
- Integrated force gauge provides real-time pulling tension readouts to protect cable limits.
- Universal boom mounting brackets couple direct to standard Greenlee puller boom systems.
- Circuit breaker overload protection shuts down motor power before internal gear damage occurs.
Load Cell Tension Bench Telemetry
Electrical ammeters record 14.8 Amps draw at 120 Volts during continuous 9500 lb pulls in low gear. Planetary gearbox casing temperature stabilizes at 158°F after twenty minutes of unbroken high-tension operation. Line speed registers 9.6 feet per minute under 9000 lb continuous rope tension. Capstan spool surface temperature climbs to 144°F from rope friction. Acoustic sound pressure meters record 82 dBA at one meter during heavy pulling cycles.
Rigging Bounds Fleet Service Directives
Never change between high and low gear while pulling rope remains under tension. Shifting speeds under load shears internal transmission drive pins and drops cable tension abruptly.
- Check planetary gearbox oil level through the sight glass before every major cable pull.
- Inspect capstan spool surface for rope grooving and polish burrs smooth every month.
- Test the mechanical overload circuit breaker and verify switch cutoff function every 50 hours.
