    FOREWORD Read this entire publication and retain it for future reference. For inquiries regarding your BRADEN Planetary Hoist or this publication, please contact BRADEN Service Department at 918-251-8511, Monday through Friday, 8:00 a.m. to 4:30 p.m. (CST). 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 BRADEN Model PD12C and PD15B series hoist.

  • Page 4: General Safety Recommendations

    GENERAL SAFETY RECOMMENDATIONS Safety and informational callouts used in this manual include: WARNING CAUTION WARNING – This emblem is used to warn against hazards CAUTION – This emblem is used to warn against potential and unsafe practice which COULD result in severe personal or unsafe practices which COULD result in personal injury injury or death if proper procedures are not followed.

  • Page 5: Theory Of Operation

    THEORY OF OPERATION DESCRIPTION OF HOIST open at 300-500 psi (20.7-34.5 bar) cracking pressure the pilot pressure becomes flow-dependent and modulates The hoist has four basic component parts: the spool valve opening which controls the lowering speed. Refer to figures 1, 2, and 3. 1.
  • Page 6 THEORY OF OPERATION of oil flowing through it and the speed at which the load will be lowered. Increasing the flow of oil to the motor will cause the pressure to rise and the opening in the brake valve to enlarge, speeding up the descent of the load. Decreasing this flow causes the pressure to lower and the opening in the brake valve to decrease thus slowing the descent of the load.

  • Page 7: Hoist Installation

    HOIST INSTALLATION 1. The hoist should be mounted with the centerline of the drum in a horizontal position. The mounting plane of the base may be rotated in any position around this centerline. 4. The vent plug must always be located above the horizontal centerline.

  • Page 9: Recommended Fastener Torque

    RECOMMENDED FASTENER TORQUE Higher or lower torques for special applications will be specified such as the use of spanner nuts, nuts on shaft ends, jam nuts and where distortion of parts or gaskets is critical. Lubricated torque values based on use of SAE 30wt engine oil applied to threads and face of bolt or nut. Avoid using thread lubricants (such as anti-seize compound) as the applied torque may vary by 10-40%, depending upon the product used.
  • Page 10 WIRE AND SYNTHETIC ROPE INSTALLATION 4. Install the wedge as shown in Figure 1 then pull the slack from the cable. NOTE: An early style wedge was designed to accommodate multiple sizes of wire rope. It may need to be inserted large end first or small end first depending on the diameter of rope being anchored.

  • Page 11: Two-Speed Motor Case Drain Plumbing

    WIRE AND SYNTHETIC ROPE INSTALLATION 3. Splice an eye at the end of the rope to be inserted into the anchor pocket. It is recommended to wrap the eye with electrical tape to allow the rope to slide into the pocket easily. 4.
