At Givens Engineering, we’re redefining what a crane can do. Our patent-pending design allows a crane to seamlessly roll over a gap in the rail, enabling a commercial dock door to close through it.
This means that trucks do not have to enter your building; Our innovative crane efficiently receives the material outside, lifts it, and then smoothly returns inside. This ensures that elements like snow and dirt stay exactly where they belong – outside, with the truck.
This novel type of crane has been in use at Givens Engineering for several years, with good success.
Heavy loads are continuously lifted from trucks outside and hauled inside on a daily basis at Givens Engineering in London, Ontario.
Trucks pull up outside the building and are unloaded by the crane outdoors. With the roll-up door (a standard roll-up door) open, the crane drives back inside bearing the load.
No modifications to your dock or roll-up door are necessary!
The key to the success of the Indoor Outdoor Crane is a specially-designed, very long end truck, built to roll over a gap in the rail.
Each bridge (the moving rail) is driven by 2 tractor drives, as shown, which propel the bridge over the gap. When one tractor is passing over the gap, the other will be driving the load forward. The tractors can be either air or electric and are controlled from the same pendant as the hoist.
Ordinarily, very expensive indoor space is wasted by devoting a portion of the building to a truck entrance; with the indoor outdoor crane, trucks can remain on the outside.
The Indoor-Outdoor Crane can be seen in action in this Youtube video:
