Genie S-125 Boom lifts tech specs

Overview

The Genie S-125 is built for jobs where ordinary boom lifts have already admitted defeat. This is a true high-access machine for steel, shutdown maintenance, facade work, and major construction where the main question is not whether it reaches high enough, but whether the site is ready for a machine this serious.

Performance & Efficiency

With a 40.17 m working height and 24.38 m horizontal reach, the S-125 is clearly aimed at ultra-high access work. It shines on structural steel, industrial shutdowns, facade installation, and other jobs where vertical reach is the main reason the machine is on site. The 227.02 kg unrestricted platform capacity is enough for operator-plus-tools work, but this is more of a reach-first machine than a heavy basket-load machine.

Maintenance & Ownership

The Deutz TD2011 L04i diesel is a known industrial engine, and the S-125 is built like a true project or fleet asset rather than a casual occasional-use machine. With 151.02 L of fuel and 208.18 L of hydraulic capacity, it is clearly meant for demanding work cycles and crews who regularly use large booms properly.

In Cabin & Interior

There is no cab, but the platform is properly sized for real access work. Platform dimensions of 244.09 cm by 91.19 cm give workable space, and the 160° platform rotation helps operators line up on awkward points with less repositioning and less wasted time.

Safety Features

Safety comes from stable machine mass, controlled boom geometry, and a design built for serious height work. The main advantage is dependable high-access positioning; the main caution is obvious, this is a very large boom lift that demands proper ground conditions, planning, and space.

In Comparison

Genie S-120
A close in-family comparison with slightly less height but stronger unrestricted platform capacity.

Genie S-85
A smaller, easier-to-place option that gives up a lot of reach in return for better site flexibility.

Genie S-125
The height-first choice for buyers who need real ultra-high access and are willing to live with the larger footprint.

Verdict

Rated 5 stars, the Genie S-125 is an excellent boom lift for contractors who need extreme working height and strong long-reach access for industrial, structural, and major construction work. It makes the most sense when height is the whole buying argument and anything smaller would just be pretending.
