When glaziers are called upon to install large glass or a curtain wall, it’s sometimes efficient and prudent to use a crane to complete the work.

But, even when you effectively recognize an appropriate scenario for crane usage, what factors need to be considered?

When using a crane with a glazing robot or manipulator, there are several considerations that need to be determined to identify the best equipment solution.

Let’s take a look.

Size, Weight and Dimensions

To properly accomplish a unique job, it is important that a correctly sized below-the-hook vacuum manipulator be outfitted with an appropriately sized array and cup capacity.

Instead of adopting a “one-size-fits-all” approach, you can work with professionals at a manufacturer like Ergo Robotic Solutions. They will work with you to correctly assess your individual situation and determine the safest configuration(s) and cup/array size(s) to fit your specific needs.

Cantilever Reach

Often, there is a soffit or outcropping on the building that needs to be navigated in order to install glass correctly and safely underneath it. Things aren’t getting simpler – architects are designing more and more complex buildings to exceed modern commercial and residential expectations.

Instead of folding in the face of these challenges, you can find a solution that adapts to your scenario. At Ergo Robotic Solutions, we have crafted units with excess of 17-foot reach from the crane hook to the glass, and we’re always open to custom requests.

Ergo Robotic Solutions has even made machines to install glass on air-traffic control towers. The believe that no application is too large or complex.

Manipulator or Lifter?

Often, basic units provide one function – vacuum suction. Beyond that, everything is handled manually, increasing the time spent, money wasted, a lack of safety, and headaches incurred.

With a unit that includes hydraulic power and wireless control, glass can be rotated or lifted from either an “on-edge” or “flat” position and manipulated to any position in between.

Ergo Robotic Solutions provides powered manipulators like the SkyHook WPI Window Placement Instrument and Plumb-Line 2200, negating the manual, rope-based struggle against physics to get glass to stand vertically.

The applications are wide-ranging, including bringing glass perfectly vertical for installation or laying it perfectly flat for installations like large skylights and more. 


Safety should always be the No. 1 priority on any jobsite, and simple manipulators that only provide vacuum suction don’t support that purpose.

Lifting and manipulating heavy glass by hand is dangerous, and having a hydraulically powered machine on hand to do that work keeps everyone safer throughout the project.

Ergo Robotic Solutions equipment also provides multiple feedback lights and alarms that further boost safety and preparedness.

Glass Overhang Limits

A key consideration when determining the best array setup is the distance from the cup to the edge of the glass. If incorrect, this can cause bending and breakage, and this consideration is even more critical for skylight applications.

At Ergo, we have the experience to safely prepare an appropriate cup array to lift skylights up to 10,000 pounds.
