PB30 Cable Pipe Burster

A compact cable-fed pipe burster with 30 tonnes of pull, for replacing pipe where a full-size rig will not fit

  • Bursts existing pipe from 50mm to 60mm
  • 30 tonnes of pulling force
  • One metre square footprint
  • Runs off a power pack or a compact excavator
  • Splits into four pieces and fits in a van
  • Bursts pitch fibre, cast iron, PE and PVC

The PB30 is a compact cable-fed pipe burster for replacing existing pipe from 50mm to 60mm along its own line. It pulls with 30 tonnes of force from a footprint of about one metre square, allowing it to work in places a full-size bursting rig cannot reach.

The PB30 bursts all the common pipe materials used today: pitch fibre, cast iron, pig iron, PE and PVC.

Use Cases

  • Replacing a failing drain, sewer or service pipe in a back garden or yard
  • Pipe renewal on sites where a full-size bursting rig cannot be positioned
  • Lateral renewal run from a house, a basement or a clean-out
  • Utility renewal where the working area is small
  • Renewal under drives, patios and landscaping
  • Replacing pitch fibre drains, a common failure in post-war housing
  • Jobs where the kit has to be carried in rather than towed or craned

How Cable Bursting Works

A full-size static burster pushes a string of rigid rods through the old pipe. The PB30 uses a 19mm swaged steel cable instead, which is why a machine like this is also called a rope burster. The crew feed the cable through the old line from the launch pit, couple a bursting head and the new HDPE pipe onto it at the far end, and the unit hauls the whole assembly back through. The head splits the old pipe and pushes the fragments out into the surrounding ground, and the new pipe follows into the space behind it.

The cable is what makes the machine small: there is no rod string to transport, store or lay out on site. The bursting heads negotiate bends of up to 45 degrees, and the new pipe can be the same size as the old one or larger.

When to Use a PB30

Access is what decides it. A Grundoburst needs room for the rig, the rod string and a trailer to bring it all in. The PB30 breaks down into four pieces, travels in a van and works from a pit around a metre square, so it reaches back gardens, basements and yards a full-size rig cannot get near. Machine digging is not always needed to open the pits.

The trade-off is capacity. For mains renewal in open ground the larger rig is the better tool. For laterals and connections on tight sites, the PB30 is often the only tool that will do the job at all.

Benefits of the PB30 Cable Pipe Burster

  • Renews pipe on sites where no other bursting rig will fit
  • Pulls at 30 tonnes and up to 3 metres per minute
  • Runs off a power pack, a compact excavator or any hydraulic supply giving 3,000 psi and 13 gpm
  • Assembles and strips down by hand, without lifting plant
  • Built for rough site conditions
  • Biodegradable hydraulic fluids throughout

What Comes With PB30 Hire

We supply the bursting unit, the resistance plate and the cable, with the bursting head matched to the diameter and material of the pipe you are replacing. Tell us what is in the ground and what is going back in, and we will specify the tooling.

You will need a hydraulic supply. A compact excavator or backhoe will run it if it delivers 3,000 psi at 13 gpm, and we can supply a dedicated power pack if not. We also hire towing heads for connecting the new pipe, and trench boxes and shoring equipment if your pits need support.

Common Questions

What size pipes can a PB30 replace?
The PB30 is supplied with tooling for replacing 50mm to 60mm pipes, covering small-diameter service pipes and laterals. For pipes larger than 60mm (from 50mm up to 400mm), use the Grundoburst 400G or 800G.
What pipe materials can a PB30 burst?
A PB30 bursts pitch fibre, cast iron, pig iron, PE and PVC. Pitch fibre drains are a common job, because they were laid widely in post-war housing and deform as they age. Tell us the material and we will match the bursting head to it.
How much space does a PB30 need?
The PB30 works from a launch pit of roughly one metre square, and the unit itself measures 560mm by 600mm by 1,000mm. Pit depth is set by the depth of the pipe you are replacing. That footprint is what lets it work in back gardens, basements and yards.
Can a PB30 run off a mini excavator?
A compact excavator or backhoe will run a PB30 provided it delivers 3,000 psi (207 bar) at a flow of at least 13 gallons per minute. If your machine cannot supply that, we can supply a dedicated hydraulic power pack instead.
What is the difference between cable bursting and rod bursting?
Cable bursting pulls on a steel cable fed through the old pipe; rod bursting pushes a string of rigid rods through it first, then pulls them back. The cable system needs far less room and no rod handling, which is why the PB30 is so much smaller than a rod-fed rig.
Should I use a PB30 or a Grundoburst?
Choose the PB30 for 50mm to 60mm pipes when access is restricted, as it works from a pit about a metre square and arrives in a van. Choose a Grundoburst for pipe diameters larger than 60mm and higher pulling capacity.
What is the maximum pull distance for a PB30?
Pull distance is set by the length of cable on the unit, and cable lengths run up to around 45m. Tell us the length of the run when you enquire and we will match the machine to it.
Can SEL look at the site before pipe bursting?
We can visit your site before the work starts, to look at access, the pit positions and the condition of the existing pipe. On restricted sites this is worth doing, because access is what decides whether the PB30 or a larger rig is the right machine.
