  • Page 6: Introduction

    This Operation Manual details the specifications, operation, maintenance and safe use of the GO-A8-PW Pneumatic Hopper Car Gate Opener. Experience has shown that the GO-A8-PW Opener will open the most difficult car gates. However, the same experience demonstrates that total satisfaction in use depends on attention to detail in operating and maintaining the unit.

    The air inlet is a 1" NPT opening with a full-port, Universal (Chicago type) Coupling. The Coupling supplied is the recommended fitting for the GO-A8-PW. Replacing the Coupling with a quick-connect type plug will restrict air flow to the Impactor.
  • Page 11 TOOL BOX The Tool Box, bolted to the front face of the Pivot Guard, provides easy access storage for essential GO-A8-PW accessories. When not being used, the Drive Fitting, Swage Tool and Anvil Extensions should be stored in the Tool Box, and not on the Impactor's square drive.

    The Pin should be reinserted into the correct pinhole on the Pivot Guard when the wheels are in the desired position. A label located on the Pivot Guard, See Figure 3, shows which pin hole is used to lock the GO-A8-PW's wheels in the desired position.

  • Page 13: Figure 4 Pivot Pull Switch Label

    PIVOT PULL SWITCH The Pivot Pull Switch is a pneumatic actuated valve that controls the movement of the GO-A8-PW's wheels and Height Adjustment Forks. When the Switch is in the PIVOT position, the wheels will rotate so that they are parallel to the railcar.

  • Page 15: Pre-Start Check List

    Secure hose couplings with safety pins, clips, cables or chains. Each day, before opening any car gates, operate the GO-A8-PW, free- speed, for about 5-minutes. This will allow oil to coat the Impactor's internal components.

  • Page 16: Compressed Air Treatment

    VII. COMPRESSED AIR TREATMENT The GO-A8-PW Hopper Car Gate Opener is designed to operate with a clean, dry air supply at the required pressure (85 to 90-PSI) and air volume (114 CFM). Dirty and wet air will result in sluggish operation, more frequent repair and replacement of parts due to sticking, jamming and rusting of wearing parts.
  • Page 17 FILTER: Designed to operate at 250 PSI max pressure and in a temperature range of 40°F to 200°F. Filtering out of dirt and foreign particles, and the separation of moisture is automatic with air flow. There are no moving parts and no adjustments are necessary.
  • Page 18 IMPORTANT For cold weather operation, such as winter conditions (below 40° F), when the GO-A8-PW is used outdoors or in an un-heated service area, the Lubricator should be filled with a Winter Grade Air Tool Oil (PN: 40007).

    VIII. OPENING CAR GATES Roll the GO-A8-PW Opener up to the hopper gate until you "rough spot" position the Opener's output drive with the Railcar Gate's Capstan Socket. Using the CAPSTAN SWAGE TOOL (optional accessory, PN: 33-11120), clean-out and square-up the Capstan Socket on the Car Gate so that the CAPSTAN DRIVE FITTING on the Impactor's Output Drive can be aligned properly, and fully seated in the Railcar Gate's Capstan Socket.

    IX. CLOSING CAR GATES Roll the GO-A8-PW Opener up to the hopper gate until you "rough spot" position the Opener's output drive with the Railcar Gate's Capstan Socket. Re-examine the Capstan Socket. Look for rounded edges, spalling or mushrooming. If needed, re-use the Swage Tool to square-up the Socket.
  • Page 24 If the Car Gate will not move, STOP using the GO-A8-PW Opener and notify your supervisor. Do not use other opening devices (pry bars, multipliers, etc.) in an attempt to "Help" the GO-A8-PW Opener. Once the car gate is fully closed pull the Pivot Locking Pin from the Pivot Lock Pin hole and push/pull the Pivot Pull Switch to the Straight position.

  • Page 25: Height Adjustment

    X. HEIGHT ADJUSTMENT The height of the Gate Opener’s Drive Shaft can be adjusted to help align the Drive Fitting with the Capstan. By repositioning the wheel axle pins, the Impactor can be raised or lowered up to 4”. To Adjust the height: Pivot the wheels to the Straight position (parallel with Impactor).

  • Page 26: Storage

    XI. STORAGE When not in use the GO-A8-PW should be stored in a clean, dry & sheltered area, safely out of the way. If a sheltered area is not available and/or not practical, WORKMASTER's water-proof, puncture and tear resistant Protective Cover will provide excellent protection from both the elements and unloading site debris.
