Page 4: Foreword
FOREWORD Read and understand this entire publication before operating or servicing your BRADEN winch. Retain this manual for future reference. The minimum service intervals specified are for operating hours of the prime mover. The following service instructions have been prepared to provide assembly, disassembly and maintenance information for the Model BG3B series winch. -
Page 5: General Safety Recommendations
GENERAL SAFETY 10. Be sure of equipment stability before operating winch. RECOMMENDATIONS 11. The winches described herein are neither designed nor intended for use or application to equipment used in the lifting or moving of persons. Safety for operators and ground personnel is of prime con- cern. -
Page 6: Theory Of Operation
THEORY OF OPERATION The hydraulic motor shaft is directly splined to the brake coupling which is connected to the sun gear of the plane- tary reduction set. The planet carrier is splined to the bear- DESCRIPTION OF WINCH ing support end plate and cannot rotate. The hydraulic motor rotates the brake coupling and sun gear, driving the planet gears which in turn drive the ring gear/cable drum. -

mounted on a pivoting surface, the vent plug must remain above the centerline of the cable drum to pre- vent gear oil leakage. 7. Refer to "Dimensional Drawing" for relationship between drum rotation and which port is pressurized. WIRE ROPE INSTALLATION Since the static brake on this winch is "effective both direc- tions", cable can be wound onto the drum in either direc- tion. -

Page 11: Recommended Gear Oil
RECOMMENDED PLANETARY GEAR OIL Field experience, supported by engineering endurance tests, indicates the use of the proper gear oil and a program of reg- ular preventive maintenance will help provide extended gear train life and reliable hoist brake performance. For this rea- son, BRADEN has published the following specifications to assist in determining which lubricant is best suited to your appli- cation. -
