EZ Hauler 3400 LP


The EZ Hauler 3400 LP can lift 3400 pounds. It has 2X travel stability, and when collapsed is under 7 foot in height. The EZ Hauler 3400 LP is Tier IV Compliant.

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

The EZ Hauler 3400 LP is the predecessor of the EZ Hauler 55MLP. It 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 3400 LP can lift 3,400 pounds, and can extend to more than 32 feet. The overall height (when collapsed) is 7 feet and the length is 15 feet (including crane – when collapsed). Don’t let its small size fool you. The EZ Hauler 3400 LP packs a big punch, and can go just about anywhere.
