  • Page 4: Introduction

    INTRODUCTION The planetary slip drive rotation utilizes both a mechanical parking brake and a hydraulic valve braking system. There are three parts to the rotation system on a Digger Derrick to protect the unit from structural overload of the boom or rotation system. 1.

  • Page 6: Bring The Unit Up To Operating Temperature

    STEP 1: Set-up Bring the unit up to operating temperature. Operate the rotation for several revolutions in each direction to prime the hydraulic lines. Locate a suitable anchor capable of holding 2500 lbs. in an area with no overhead obstructions. The area on each side of the anchor must be clear to be able to position the boom on both sides and apply side load.
  • Page 7 STEP 1: Set-up With a General 95 position and set up the truck near the anchor so the load line can be positioned to pull with the side pull attachment at 329 inches from the centerline of rotation. This should be fully retracted.

  • Page 8: Setting The Minimum Rotation Pressure

    STEP 2: Setting the Minimum Rotation Pressure Set the counter-balance valves, C1 and C2 or CB1 and CB2 located in the rotation slip drive hydraulic manifold, to 800 – 1,000 PSI. This is accomplished by installing a hydraulic pressure gauge at the inlet of the derrick control valve.

  • Page 9: Boom Position

    New Style after 1/1/2016 STEP 3: Boom Position With the truck in the working position, rotate the boom off the back or side placing the sheave head approximately four to six feet off the ground. The boom should be positioned so the anchor is perpendicular to the boom as shown in the diagram on page 5.

  • Page 10: Connecting The Load Line To The Anchor

    STEP 4: Connecting the Load Line to the Anchor Attach a load cell between the load line and the fixed anchor using a side pull sheave. Do not try to side pull without this adapter or load line will be damaged. The side pull sheave is attached to the second and the third is extended enough to prevent rope damage and allow the line to align with the side pull sheave.

  • Page 11: Verifying Minimum Parking Brake Force

    STEP 5: Verifying Minimum Parking Brake Force Remove the hydraulic line from port B on the rotation manifold to brake on rotation gear box. Cap port B and leave the port on brake open to atmosphere. While monitoring the load cell, operate winch up to achieve a minimum force of 2000 lb.

  • Page 12: Setting Hydraulic Motor Force

    STEP 6: Setting Hydraulic Motor Force (stall) Ensure brake line is reconnected from Step 5. Using the lower control, rotate away from the fixed anchor until the rotation stalls. Adjust relief cartridges, R1 and R2, in the rotation slip drive hydraulic manifold, until the proper load cell reading is achieved as stated in the Hydraulic motor force (stall) value or the quick reference section of the Maintenance manual.
