The Poweram Model 9000 is designed to help you do a tough construction job – installing and/or replacing underground utility service lines where trenching is not possible or desirable.

This rugged, dependable machine installs new underground utilities by pushing steel rods under roadways, etc. and pulling the required pipe or cable back.  The Model 9000 is designed to rotate the rod string as it is being pushed.  This increases the accuracy of the push and allows for the use of steering techniques to guide the path.   When tracked by an electronic locating device such as the Radiodetection RD385 DataBore, this machine can keep the rods on line and grade and/or make a curved push to go under or around an obstruction.

The Model 9000 can also be used to replace existing lines by pulling pipe splitting and/or bursting tools through the old pipe and pulling a new pipe into the same space.   The new pipe can be the same size or larger than the old pipe.

One person can operate the Model 9000. It has two hydraulic cylinders controlled by one valve, which puts the operator in control of the machine and his/her own safety.  A pressure gauge gives the operator constant feedback on the amount of force being used. The twin cylinders actuate the patented jaw system that grips the push rods.  They apply their force at the centerline of the push rod, so they do not introduce any bending forces.  The push centerline is 9 inches above the bottom of the machine. The Model 9000 can pull up to 8" pipe (or two 4" pipes) in most soil conditions.   Larger pipe can be installed in suitable soils. The longest practical distance for accuracy depends on soil conditions and operator experience.

The Model 9000 has two additional hydraulic cylinders that extend the back plate to hold the machine securely in the work pit.  The machine length can be varied from 5’3" to 8’3".  When the 5’ long push rods are used, the machine must be extended to at least 6’10" long to have room to add and remove the rods within the length of the machine.  If 3’ or 4’ long rods are used, the overall length could be as short as 5’3’ and still allow room to add and remove the rods within the length of the machine.

The Model 9100 is the same machine except that it does not have the back brace cylinders.  The back plate can be adjusted manually to suit the rods being used and/or to the length of the shoring box.  We recommend using the model 9100 with the Model 9150 Safety Shoring Box when using the 3’ or 4’ long rods, and the Model 9160 Safety Shoring Box when using the 5’ long rods. The Safety Shoring Box not only protects the operator; it also provides a faster and more stable set-up.

POWERAM MODEL 9000 SPECIFICATIONS:

See our catalog for more detailed information about accessories. And/or: Let us know what work you need to do and we will help you select the right accessories for your jobs.

Poweram Accessory Tote Boxes are designed to store and carry the push rods, push heads, expander cones, couplings, and other tools needed at the job site.  They are heavy-duty steel boxes built to be lifted by overhead hoisting or by fork lift.  The latches will accept a padlock.

The Model 9000 will rotate the push rod string about 1/3 of a revolution for each foot of advancement.  This improves accuracy when using a flat or stepped push head, and allows for the use of steering heads to correct and/or direct the push.  The rotation device is easily disengaged to allow course corrections and for pull back.

The Model 9000 is limited to 2,500 p.s.i. working pressure.  The control valve has a built in relief that is factory set to limit the pressure to 2,500 p.s.i.

An operator’s manual is sent with each machine to help you use the equipment safely and productively, and to help you keep it in top working condition.  It will help you get better acquainted with the Model 9000 and with the various techniques used to make efficient installations and/or replacements of underground utility lines.

The Model 2613 Portable Hydraulic Power Unit is designed to provide the right oil pressure and flow for the Model 9000.  25-foot long hydraulic hoses and couplers are included with the Power Unit.

Your backhoe, boom truck or other lifting device will be needed to unload the machine and place it into the pit.  The machine weighs 1,500 lbs.; the machine and shoring box together weigh 2,700 lbs.

The work trench required for the Model 9000 in the Model 9160 Shoring Box is 3’10" wide x 7’6" long (3’wide if the shoring box is not used).

Three types of push heads are available from our stock.  The flat push head is most commonly used. It works well in most soils and is not easily deflected by small rocks or by sudden changes in soil conditions.  The stepped push head is often used as an all-purpose head.  It is easier to push than the flat head, and it works well in uniform soils, but it may be deflected more easily.  The pointed push head works best in tightly compacted uniform soils and to pierce through a section that has stopped a flat push head. It is possible to penetrate shale, sandstone, and similar materials with the pointed or stepped heads.

The 5-foot long push rods are 5’2" long overall, so each rod adds 5 ft. to the length of the string.

The 4-foot long push rods are 4’0" long overall, so each rod adds 3.833 ft. to the rod string.

The 3-foot long push rods are 3’0" long overall, so each rod adds 2.833 ft. to the rod string.

The Jaw Stop Pins must be in the forward holes for pushing.  They allow the jaws to grip the push rod on the forward stroke, but prevent them from gripping on the return stroke.  Simply move the pins to the rear holes for pulling.

When the push head reaches the receiving trench, it is removed and the swivel connector or proper expander cone is attached to the required service line can be pulled in. To pull a large expander in very tough soil conditions, you may want to pull a small expander through first. A rod pulling adapter (p/n 382) can be attached to the smaller expander and rods added as it is pulled back to the machine. This technique saves time and keeps a rod string in the hole.

The swivel connector (p/n 316) is used to pull small diameter pipe and cable that do not require an expanded hole. A "Chinese finger" cable grip (see our p/n 357) is often used to attach these smaller pipes and cables to the swivel connector.

POWERAM expanders are about ½" larger than the standard pipe coupling they are designed to pull (e.g. the outside diameter of the 2" pipe expander is 3"). We stock expanders for 2", 3", 4", 5", 6", 8", 10", and 12" pipe, as well as for double 2", 3", 4", and 5" pipes. Couplings for pulling threaded and unthreaded pipe are stocked in most sizes. Other sizes, or expanders for pulling multiple pipes of different sizes, or couplers for welded steel pipe can be furnished to order.

The p/n 303 M-F Adapter coupling is required to attach the expanders to the solid push rods.

In normal soil, the Model 9000 will pull up to 8" pipe. 12" and larger pipes have been installed in suitable soils.

We can supply systems for keeping glued and/or rubber joints from coming apart during pullback.

Our catalog has photos and descriptions of all the tools referred to above, as well as other accessory items designed to help make your work more productive. We strive to keep every item in stock so that we can fill your order as quickly as possible.

POWERAM can furnish Radiodetection electronic locating equipment to trace the progress of a push and/or to help guide the push for greater accuracy. Several models are available, including systems for locating existing utilities and for directional pushing. Contact us for more information.

POWERAM hydraulic rod pusher/puller machines are being used to replace existing gas, water, and sewer lines by splitting and/or bursting the old pipe and pulling in a new one. Check with us for details.

We make other models that could fit the work you do and make it easier and more profitable.
