The AMPJACK®
Tower Raising System
The AMPJACK® tower raising system is essentially a “crane in a box” — deployed by a small crew, virtually anywhere in the world. It is fully modular and is engineered to lift just about any tower design — from simple, single circuit towers to complicated, multiple circuit towers.
How It Works
A simple idea to solve complex problems
Basically, we use an easy-to-install and easy-to-operate custom hydraulic system. The AMPJACK® mounts inside the body of the transmission line tower, which is a safe working zone for the crew where limits of approach are a concern.
Once installed on the tower, the AMPJACK® takes the entire load of the tower section and conductor which the tower supports and then raises it to the utilities specified amount.
Once the tower is lifted, new tower framing is bolted in place and the Ampjack is removed from the tower.
This means the tower can be raised without de-energizing the existing line, saving costly outages during the raising of the tower.
Raise Towers While Energized
No outages, no downtime. The AMPJACK® tower raising system provides high-voltage transmission without powering down the lines! Effectively optimizing power line resources, maximizing capacity and satisfying the growing demand for power around the world.
With the ability to safely lift the towers while the lines are energized, our utility clients save costly outages, outage planning, contingency planning and scheduling while maintaining system reliability.
Now that’s a bright idea.
Eco Friendly
The AMPJACK® system is compact, efficient, and designed to go where traditional tower-raising equipment can’t. A small, specialized crew of just 8–10 and a few standard trucks are all it takes to execute a precision lift.
Packed into just 8–12 custom-engineered job boxes, the entire AMPJACK® system travels light — easily towed by a flat-deck trailer or airlifted to remote sites. No cranes. No convoys.
AMPJACK® thrives where others stall — navigating tight trails, narrow right-of-ways, and terrain unreachable by heavy machinery. When road access ends, heli-lift deployment takes over.
Modular and efficient by design, AMPJACK® minimizes environmental disruption and often reduces or eliminates the need for extensive permitting. That means faster planning, fewer approvals, and lower ROW access costs.
