Built For The Ditch

The Pit Bull is the workhorse of the McElroy machine line with a marked level of endurance. The carriage alone provides all the muscle you need to fuse small- and medium- diameter pipe when wheeled- and track-mounted vehicles are not necessary. The carriage, heater, insulated heater stand and Hydraulic Power Unit (HPU) are separate components that can be situated in various arrangements to allow flexibility in confined environments.


Rugged & Reliable

Ready for the toughest jobs

The Pit Bulls are capable of fusing pipe all day long with consistent, high-quality results. They offer the same power of any same-sized rolling or tracked fusion machine, and most will conveniently fit on any of McElroy's wheeled or tracked vehicles. All of the McElroy Pit Bulls feature serrated jaws and inserts to keep the pipe from slipping during fusion. When jobs are down and dirty, the Pit Bull is your go-to machine.

Small Footprint

Designed for Tight Spaces

Compact and portable, the Pit Bull carriage is built specifically for pipe fusion in the trenches. On tight installations, the medium-diameter machines can be converted from a four-jaw to a three-jaw carriage for an even more compact fusion unit in the ditch. The smaller-diameter models are made primarily of surface-hardened aluminum which makes it durable yet light weight so that it can be physically carried from joint to joint.

Small Footprint
Patented Centerline Guidance System

Consistent Joint Quality

Patented Centerline Guidance Provides Equal Distribution of Force

Centerline Guidance is a balanced force system that is unique to all McElroy machines. It places the centerline of the pipe clamping jaws on the same plane as the pipe's centerline. The force applied during the fusion passes through the center of the pipe, producing an equal distribution of force around the diameter of the pipe which results in an even, continuous bead formation and quality joint.

DataLogger® Compatible*

Record & Analyze Fusion Joint Data

The medium-diameter Pit Bull machines are compatible with the McElroy DataLogger, a handheld computer that records and documents the key parameters of the fusion process. These joint records are used to verify that proper fusion procedures have been followed prior to installation, which is a growing jobsite requirement. Joint records from the DataLogger can be stored and analyzed in the Vault™, a secure server on the internet. This allows quick and easy sorting, tagging and sharing of joint records by machine, joint, operator, device or job.
