Overhead Cranes

Move up to the next level in overhead cranes…
Engineered for the lowest rail weight, the highest strength and the greatest versatility.


Our bridge cranes are engineered for the lowest rail weight, the highest strength and the greatest versatility.

Advantage: Extremely Lightweight Bridge


G-Rail™ overhead crane profiles combine with Slant-Truss bolt-on reinforcements to create one of the lightest lifting systems in the world.When you have to move a load quickly, the importance of a lightweight bridge becomes obvious!

The Slant Truss (patented) is an all-aluminum bolt-on system that instantly increases the stiffness of the G-Rail™ overhead bridge Crane by several times. When spans approach 25’, 30’ or even 35’, the weight of the bridge increases exponentially, making many traditional cranes ergonomically impossible –there is simply too much weight to pull back and forth quickly. The extremely lightweight G-Rail™, reinforced with the Slant Truss, makes long spans much more feasible.

Advantage: Low-Running Friction


The key to smooth, friction-free running is in the end trucks.

G-Rail™ end trucks are rigid, as opposed to articulating, that is, bridge cannot skew with respect to the runways. This means that the whole bridge moves along evenly, with less “pendulum effect”.

Our end trucks are machined from aluminum, not welded, making them very accurate and square-fitting, which eliminates the possibility of binding. Notice the size of the guide wheels at either end, which reduces friction further.

Advantage: Completely Free-Standing Support Frame


The support frame for the G-Rail™ crane is one of the strongest on the market.

Competitors state that unless movement of the support frame can be tolerated, attachment to part of the building structure may be necessary.

G-Rail™ cranes can be completely self-supporting, due to some of the largest columns in the industry. For example, C250 cranes have 5” x 5” columns, where competitors can be 3” x 3” and 4” x 4”.

Also, G-Rail™ cranes are stiffened by recruiting the runway itself to rigidize the top of the frame. In effect, the runways become part of the frame! In particular, the saddle clamp, unique in the industry, connects the header absolutely rigidly to the runway.

Notice that the headers are made of tube — not I-beam or channel– adding to the stiffness in the direction of the runways.

Overhead G-Rail™ Cranes Are Versatile


We understand that a perfectly rectangular crane is not always possible, that there are often obstacles to be avoided.

If you have an unusual requirement, give us a call… we can probably create a solution.

The Slant Truss


The Slant Truss can be added to the G-rail™ or not, as the loading requires. G-Rail™ does not need to be reinforced if the span is 4m (13’) or less.

If the loading is less than the maximum rail capacity, longer spans than 4m can be used without a truss.

Disengageable Tractor Drive


Our AT tractor drive disengages from the rail when not in use, allowing the load to ‘free-wheel”. The operator can choose to pull the load manually or engage the tractor at any time.

For heavy, continuous use, the air motor should be supplied with a small amount of oil; for intermittent use, the tractor can be run oil-free.
