Bridge Cranes

Move Up to the Next Level in Cranes

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

G-Rail Bridge Crane Manufactured by Givens Engineering

Advantage: Lightweight Bridge Cranes

 
The crane profile of the G-Rail™ bridge crane, combined with Slant-Truss bolt-on reinforcements, create one of the lightest lifting systems in the world. The importance of a lightweight bridge crane becomes increasingly important when you need to move a load quickly and securely.
 
The patented Slant Truss is an all-aluminum bolt-on system that significantly increases the stiffness of the G-Rail™ Bridge Crane making it one of the sturdiest bridge cranes available. When spans approach 25’, 30’ or even 35’, the weight of traditional bridge cranes increases exponentially, making them ergonomically impossible. There is simply too much weight to pull back and forth quickly. The extremely lightweight overhead crane is reinforced with the Slant Truss, makes long spans much more feasible.

Advantage: Low-Friction End Trucks

The key to smooth, friction-free running lies in the end trucks. G-Rail™ end trucks are rigid, as opposed to articulating, that is, the bridge crane cannot skew with respect to the runways. This means that the whole bridge moves along evenly, with a decreased “pendulum effect”. 

At Givens Engineering, our end trucks are machined from aluminium, not welded. This allows for an accurate and square-fit, eliminating the possibility of binding. We ensure that the guide wheels at either end of the overhead crane are properly fitted to reduce friction. 


Advantage: Bridge Crane with a Completely Free-Standing Support Frame

The support frame for bridge cranes from Givens Engineering 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 instance, C250 cranes have 5” x 5” columns, where competitor’s cranes can sometimes only be 3” x 3” and 4” x 4”.

Also, our bridge cranes are stiffened by recruiting the runway itself to rigidize the top of the frame. In effect, the runways of the overhead crane become part of the frame itself. The saddle clamp, which is unique in the industry, connects the header absolutely rigidly to the runway.  

The crane headers are made of tube - not traditional I-beam or channel, adding to the stiffness in the direction of the runways.

G-Rail™ Bridge Cranes Are Versatile

We understand that a perfectly rectangular crane is not always possible, that there are often obstacles that may need to be avoided.  If you have an unusual requirement and specification for your crane build, give us a call and we can discuss an alternative or solution to best suit your needs.  

The Slant Truss

The Slant Truss is an optional component that can be added to the bridge crane or not, depending on the needs of the load. G-Rail™ overhead cranes do 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

We create our AT tractor drives to allow it to disengage from the crane rail when not in use, allowing the load to ‘free-wheel”, giving the crane operator the choice between pulling the load manually or engaging the tractor at any time. For these tractor drives, we recommend the air motor be supplied with a small amount of oil if using frequently and continuously. However, for limited and intermittent use, the tractor can be run oil-free. 
The team at Givens Engineering can help find a solution that best suits your specific needs. Give us a call at 519-453-9008.
