Crane Base Ground Anchors

Crane Bases and Ground Anchor Cones.

Occasionally your civil engineer will decide your factory needs to have bases fitted prior to our arrival. This is usually for 1 main reason; your concrete floor is too shallow to take an overhead crane of the required lifting capacity, and the overturning moments imposed by the cranes force.

If this is the case do not worry. We can provide crane drawings and crane weights and overturning moments. If you are having foundation bases dug into your factory floor we can supply anchor cones in template form. Below you can see a before and after photograph of the anchor cones. The after pictures shows a string line down the centre.

Often clients having floor pads but in for cranes will dig the hole a little deeper, say 150mm. We can then sink the crane column into the hole and after we have finished it can be concreted over. This eliminates a trip hazard on the base. On the down side, its a bit awkward if you decide to move factory 5 years later….

AG Cranes are not civil engineers and are not qualified to to say your floor is suitable for the crane in question. We can however recommend civil and structural engineers if you think you may need one.

If you receive a crane quotation for anything over 5 tonnes SWL and the supplier of the crane says “your floor will be OK”, be wary. If you need advise on cranes, steelwork, or bases please call us today, on 01527 894825, 9.00am to 5.00pm.
