The document is a training log from TRIC Tools that describes the process and safety considerations for replacing an underground pipe using pulling equipment. It details the specific job of replacing a 4-inch underground pipe running uphill for 45 feet on a residential property in Oxnard, CA. The log provides instructions on digging an entry hole, allowing extra pipe length, trimming and heating the new pipe, attaching the pulling head to the cable, monitoring pressure during the pull, and completing the pull with an extender cage.

1. TRIC Training Log: 07-22-04 Client: Salinas Brothers, Oxnard, CA Job: Residence, to front property line, replacing 4” VCP Pull: uphill / 45’ / 4” / SDR17

2. We at TRIC Tools have specific requirements for the use and maintenance of our equipment with regard to safety and efficiency on the job. Our written and verbal recommendations coincide with safety regulations set by local, state, and national government agencies. Our clients may have standards over and above industry regulations. However, the safety equipment, apparel, and operating procedures demonstrated by our clients in this presentation may or may not comply with above mentioned government regulations.

3. Pulling hole: A hole roughly 2’ wide by 4’ long allows easy use of the extender cage. Smaller (shorter) holes require wood cribbing to complete the pull.

4. Pipe length: Allow enough extra for “bumping” new pipe with a sledge hammer at the end of the pull. This usually means between 5’ and 10’ more than the length of pipe being replaced.

5. Trimming the pipe: Carefully check alignment in the jig before and after trimming.

6. Keep it clean: Remove trimmings after each use of the blade, so as not to interfere with heating or fusing. This is especially true of the smaller jig (shown here).

7. Heating the pipe: Make firm, even contact with heating iron, then use neutral pressure. Fusing time and temperatures are also affected by weather.

8. Fusing the head: Depending on the length of the pull, the end where the head is attached can make a big difference in convenience of entry.

9. Property line: Clearing pipe from the entry hole, which in this case is downstream.

10. Cable ready: Attaching the pulling head to the cable.

11. Ready to go: Interference with traffic (pedestrian and automotive) is usually minimal.

12. A good start: Guide the head into its entry point to assure the best angle of attack.

13. Steady progress: Watching a good entry.

14. Go with the bend: Note how the cable clevis and head core “hinge” on the clevis pin.

15. Least resistance: Strive for a clean , direct, and unobstructed entry.

16. Traffic control: After assisting optimal entry angle, and after 4 or 5 feet of pull, pipe can be flexed back to a tighter arc to keep it out of the public right-of-way.

17. Watching the pressure: Whether the pull is 30 feet or 300 feet, the pressure gauge is an indispensable trouble shooter.

18. Simple and versatile: Ram can swivel 360º on pulley base, and pulley can operate at various angles against resistance plate.

19. Detensioning: Removing tension O-rings at end of pull to facilitate release of jaws.

20. Extender cage: For that all-important last foot.

21. Almost there: Keep debris away from pulley assembly to allow clear vision of pulley and cable terminator.

22. Arrival: Stop when clevis (cable terminator) is just visible inside pulley housing. Keep clevis sheath away from pulley wheel.
