EZ Hauler 55MLP


With the EZ Hauler 55 MLP you can lift 5500 pounds, but still fit the entire unit through a 36" opening. Try taking a line truck through a 36" opening!

A Utility Company's Ace-In-The-Hole

The EZ Hauler 55MLP is designed to do what a line-truck can do, but is able to work in confined spaces and hard to navigate areas. The EZ Hauler is designed to do what a line-truck can do, but is able to work in confined spaces and hard to navigate areas. The EZ Hauler is able to carry multiple utility poles and transformers to the job site for you.

EZ Hauler
The "Original" Mini-Digger Derrick




During normal navigation the tracks are wider to provide stability during transport. But with our one-of-a-kind EZ-RTS the tracks will retract under the unit which allows for passage through narrow (36″) areas. Other models have a sliding track, but in order to use them the unit must be deployed on the outriggers, but not the EZ Hauler. The EZ-RTS system works even with a load! This gives you the best of both worlds. One is a strong and powerful tracking system with the ability to carry up to 5000 pounds. Two is the self-narrowing system that enables you to go where no other equipment can..

The front outriggers fold and retract/extend via our on-board hydraulic pump and hose system.  This feature enables the EZ hauler to maintain a safe, low center of gravity (even on very tricky hills and slopes).  As a double feature, we also add an elaborate hose and quick connect system for many hydraulic attachments.

Our 360 degree work zone allows for maximum versatility and efficiency.

Defined And Refined

Yes.  We invented the mini-digger derrick.  That doesn’t stop us from continuing to improve and lead the industry.  Not because we want recognition or accolades, but because we want you to have the best possible equipment to help you with your dangerous job.
