  1. Potain HDT80 Self-Erecting Tower Crane Site Preparation 1. Determine if FAA notice to airmen is required and if flag or light is required per FAA guidlines. 2. Determine underground utilities or other obstacles impacting grounding of crane and/or generator. 3. Ensure adequate ingress/egress for crane, ballasting and erection envelope of crane (see specification sheet for erection envelop). 4. Provide space for generator or power pedestal if contractor is providing power. 5. Ensure adequate egress/ingress to fuel generator if applicable 6. Prepare Flat, level, compacted and well- drained crane surface that can support the maximum corner force of the crane. (See attached crane reaction data) Supplier will provide crane pads. 7. Ensure that erected crane has adequate clearance and separation from any existing or anticipated power lines or obstructions 8. Construct adequate barrier to keep unauthorized persons from entering the crane area. We Invest in Your Success!

When the capacity is different, modify the bearing surface accordingly, observing the height of the support ( 9? ). R = 10?9? R = 12?1? F 1?11?
